New Virtual Device CreatedEmulator RunningDepending on your Mac’s performance, it might take a little while for the emulator to start up. Pixel 7 Emulator LaunchedConclusionWith your emulator set up, you can now test your applications in a virtual environment. The next step involves installing APK apps on your emulator for testing purposes. Proceed to Installing an APK app on an Android Emulator to continue your journey. Installing an APK app on an Android Emulator After setting up your Android emulator, the next step is to install and test APK applications on it. This guide will walk you through the process of installing an APK on your emulator.Installing App via Project ViewWith your emulator up and running, it’s time to fire up your app! Go back to Android Studio and click on the green play button in the toolbar or from the menu bar, select Run . Android Studio will build your app and install it on the emulator. Installing App On EmulatorOnce the installation process is complete, your app will automatically launch on the emulator. App Installed SuccessfullyInstalling Your App via APKAnother method to installing an app on your emulator would be through an apk file. To add an apk to your device simply navigate to location of your apk or download an apk file from a trusted source online. For this example I will be using the same apk generated after building the app from the project. Since I’m using Flutter project to build this app, the location of the apk is here App Project build app outputsflutter-apkapp-debug.apk Build Location of the APK FileOnce you locate your apk, simply drag and drop the apk onto the emulator for it to install. Installing APK By Dragging & Dropping On EmulatorConclusionVoila! Your app is now running on the emulator. Take some time to explore its features and functionalities. Click around, interact with different elements, and get a feel for how it behaves. Next, we’ll explore how to use ADB with Android emulators to perform various debugging tasks. Head over to Using ADB with Android Emulators for more insights. Using ADB with Android Emulators Previously, we covered installing APK apps on your emulator. Now, let’s delve into using ADB (Android Debug Bridge) with Android emulators. ADB is a powerful command-line tool that enables communication with your emulator or device.

Use this command.bashadb install /Users/{UserName}/Desktop/test-apps/app-debug.apk Installing An APK Using ADB CommandGet Android Package Name: Get the name of the Android app’s package name in order to use the uninstall command later. With the test app lauched on the emulator, open a new terminal and enter this command below:bashadb shell dumpsys window | grep 'mCurrentFocus' Name of App Package & Main ActivityUninstall an APK: Remove an application from the emulator.bashadb uninstall com.example.yourapp Uninstalling APK Using ADB CommandConclusionThe ADB is an essential tool for Android development and debugging. Mastering its commands will enhance your ability to manage and debug your applications effectively. Up next, we’ll cover automating UI tests on Android emulators, a crucial step for ensuring your app’s usability. Continue to Automating UI Tests on Android Emulators for detailed instructions. Automating UI Tests on Android Emulators Building on our knowledge of ADB, this guide focuses on automating UI tests on Android emulators. Automated UI tests ensure that your application’s user interface behaves as expected across different scenarios and devices.Why Automate UI Tests?Automated UI tests save time and resources by running tests that simulate user interactions. They help identify bugs and inconsistencies in the UI, providing a reliable way to maintain high-quality applications.Setting Up Espresso for UI TestingAdd DependenciesYou need to add Espresso and other related dependencies in your build.gradle file of your Android app module (app/build.gradle).android/app/build.gradle defaultConfig { testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner" }Create a Test Class In src/androidTest/java and call it MainActivityTest.This test will ensure that the app is launched and ready for interaction. The test method will simulate a user clicking the plus button and verifies the resulting UI state.MainActivityTest.class@RunWith(AndroidJUnit4.class) @LargeTest public class MainActivityTest {@RunWith(AndroidJUnit4.class): This annotation tells JUnit to run the test class using the AndroidJUnit4 test runner. This runner provides compatibility with Android components and manages the test lifecycle.@LargeTest: This annotation classifies the test as a “large” test. Large tests typically involve integration testing, where multiple components of the application are tested together.MainActivity.class@Rule public ActivityScenarioRule<MainActivity> activityRule = new ActivityScenarioRule<>(MainActivity.class); @Rule public DisableAnimationsRule disableAnimationsRule = new DisableAnimationsRule();@Rule: Rules in JUnit are used to add or extend the behavior of each test method in a test class. They provide additional functionality before and after each test is run.ActivityScenarioRule<MainActivity> activityRule: This rule launches the specified activity (MainActivity in this case) before each test and closes it after each test. It provides a simplified way to test activities. The ActivityScenarioRule starts and stops the activity and also ensures that the activity is running before the test begins.DisableAnimationsRule disableAnimationsRule: This custom rule is used to disable system animations during the test run. Animations can interfere with Espresso tests by causing unexpected delays or timing issues, so disabling them ensures more consistent test results.MainActivity.class@Test public void testClickPlusButton() throws InterruptedException { // Click the plus button to open the AddEditTaskActivity onView(withId(R.id.fab)).perform(click()); // Verify that the AddEditTaskActivity is displayed by checking for the presence of the title EditText onView(withId(R.id.titleEditText)).check(matches(withText(""))); }@Test: This annotation indicates that the following method is a test method. JUnit will execute this method as a test case.public void testClickPlusButton(): This is the test method. The method name typically describes what is being tested. In this case, it tests the behavior of clicking the plus button.onView(withId(R.id.fab)).perform(click());: This line uses Espresso to interact with the UI. It finds a view with the ID fab which is the floating action button in this app and performs a click action on it. Espresso’s onView method is used to find views in the current activity’s layout, and perform is used to execute actions on those views.onView(withId(R.id.titleEditText)).check(matches(withText("")));: This line verifies that a view with the ID titleEditText is displayed and that its text is empty. This check is used to confirm that the AddEditTaskActivity is displayed by looking for the presence of an empty title EditText. The check method is used to perform assertions on views, and matches verifies that the view’s state matches the specified condition. Since this is a ToDo app, let’s enhance the test suite by adding two more critical scenarios: one for adding a task and another for deleting a task. These scenarios will ensure that the core functionalities of creating and removing tasks are working as expected.MainActivity.class@Test public void testAddTask() throws InterruptedException { // Click the plus button to open the AddEditTaskActivity onView(withId(R.id.fab)).perform(click()); // Enter text into the title and description fields and close the keyboard onView(withId(R.id.titleEditText)) .perform(typeText("New Task Title"), closeSoftKeyboard()); onView(withId(R.id.descriptionEditText)) .perform(typeText("New Task Description"), closeSoftKeyboard()); // Click the save button onView(withId(R.id.saveButton)).perform(click()); // Verify that the new task is displayed onView(withText(endsWith("New Task Title"))) .check(matches(isDisplayed())); } @Test public void testDeleteTask() throws InterruptedException { // Delete the task onView(withId(R.id.doneButton)).perform(click()); Thread.sleep(2000); // Verify that the task is deleted by checking that the item is not in the list onView(withText(endsWith("Task to Delete"))).check(doesNotExist()); Thread.sleep(2000); }Running UI TestsClick on the green play icon next to the class definition to run all tests in the class. Alternatively, click on the green play icon next to individual test methods to run specific tests. Running Android UI TestViewing Test Results Once the tests start running, the Run window will display the progress and results. The Run window shows which tests passed or failed, along with detailed logs and stack traces for any failures.Analyze Test Results Green checkmarks indicate passed tests. Red X marks indicate failed tests, with details about the failure. Yellow warning signs indicate ignored or skipped tests. Reviewing Expresso Test ResultsConclusionAutomating UI tests with Espresso provides a robust way to ensure your app’s user interface functions correctly. Next, we’ll explore performance testing on Android emulators, which is vital for optimizing your app’s performance. Proceed to Performance Testing on Android Emulators for more information. Performance Testing on Android Emulators Having covered UI testing, we now turn to performance testing on Android emulators.

Organizing Multiple Test Scenarios in Appium Using TestNG In the dynamic world of mobile application testing, managing and organizing multiple test scenarios efficiently is crucial for ensuring robust and reliable testing. Appium, combined with TestNG, provides a powerful framework to achieve this. This guide will walk you through the process of organizing multiple test scenarios in Appium using TestNG, leveraging the power of Java. Whether you’re a beginner or an advanced user, this comprehensive guide will help you streamline your test automation process and enhance your testing capabilities. We will be using the project we setup previously. Setting Up Maven ProjectLet’s navigate to the pom.xml file so we can add the TestNG dependency. We’ll be using TestNG version 7.1.0 for our project. Adding TestNG Dependency To pom.xmlTestNG Dependency (pom.xml)<dependency> <groupId>org.testng</groupId> <artifactId>testng</artifactId> <version>7.1.0</version> <scope>compile</scope> </dependency>By adding the TestNG dependency to your Maven project, you now have the necessary annotations to write and execute TestNG tests within the Appium project.Creating TestNG Class Let’s head back to our directory /src/test/java/com/test/ where we’ll create a copy of the existing FirstAppiumTest class. We’ll then rename this copy to FirstAppiumTestNG to begin restructuring the test to support TestNG. This new class will serve as our foundation for integrating TestNG functionalities. Copying FirstAppiumTest Class Pasting FirstAppiumTest Class Rename Copied File to FirstAppiumTestNGImporting TestNG AnnotationsIn the newly created FirstAppiumTestNG class, begin by importing the necessary TestNG annotations. These will include @BeforeClass, @AfterClass, and @Test.FirstAppiumTestNG.classimport org.testng.annotations.AfterClass; import org.testng.annotations.BeforeClass; import org.testng.annotations.Test; The @BeforeClass annotation will be used to set up the Appium driver before any tests are run, ensuring that the environment is correctly initialized. Similarly, the @AfterClass annotation will handle the teardown process, cleaning up resources once all tests have been executed. The @Test annotation will be applied to individual test methods, marking them as TestNG test cases.Modifying Class To Support TestNGSo what we’re going to do is remove the main() function call and close the curly bracket from our initial setup. Next, we will create a new public static AndroidDriver variable called driver. BeforeClassIn the @BeforeClass method, we will move the Desired Capabilities setup into the setup() function. This approach ensures that our Appium driver is properly configured before any tests are execute. Moving Desired Capabilities To BeforeClass MethodTest MethodIn the @Test method, we will add our simple test case from the previous guide, which is to click the Add Task button. This test will validate that our application responds correctly when adding a new task. By organizing our tests this way, we maintain a clear separation of concerns, making our test cases easier to manage and understand. Moving Scenario To Test MethodAfterClass MethodFinally, we’ll move the driver.quit() function into the @AfterClass teardown method. This adjustment ensures that the Appium driver is properly closed after all tests have been executed, cleaning up any resources used during the test run. Moving The Closing of the Driver in AfterClass MethodFirstAppiumTestNG.class (w/ Before & After Methods)package com.test; import io.appium.java_client.android.AndroidDriver; import org.openqa.selenium.By; import org.openqa.selenium.WebElement; import org.openqa.selenium.remote.DesiredCapabilities; import java.io.File; import java.net.MalformedURLException; import java.net.URL; import org.testng.annotations.AfterClass; import org.testng.annotations.BeforeClass; import org.testng.annotations.Test; public class FirstAppiumTestNG { public static AndroidDriver driver; @BeforeClass public void setUp() throws MalformedURLException { File app = new File("src/test/resources/app/app-debug.apk"); // Set the desired capabilities for your test DesiredCapabilities caps = new DesiredCapabilities(); caps.setCapability("deviceName", "emulator-5554"); caps.setCapability("platformName", "android"); caps.setCapability("app",app.getAbsolutePath()); // Initialize the Appium driver driver = new AndroidDriver (new URL("http://127.0.0.1:4273/wd/hub"), caps); } @Test public void clickingAddTaskButton() throws InterruptedException { // Add test case scenario here WebElement addTaskButton = driver.findElement(By.id("com.example.todoapp:id/fab")); addTaskButton.click(); // quick debug wait for 1 seconds Thread.sleep(1000); System.out.println("TEST PASSED!"); } @AfterClass public void tearDown() { if (driver != null) { // Close the driver session driver.quit(); } } }Adding More Test & AssertionsWhy stop here? Next, we’ll add some assertions and create two more test scenarios to highlight the beauty of TestNG running multiple scenarios and validating our expectations. We will create new tests called addingTaskToDoTheList() and deletingTaskFromTheList(), similar to the test we created using Espresso in our Android guides. We will add these methods to our file, and then we should be ready to run our tests.In our first new test scenario, we focus on adding a task to our to-do list. This test begins by clicking the “Add Task” button to navigate to the task addition screen. We verify that the user is on the correct screen by checking the presence of the title input field. Here’s how the implementation looks:Test: clickingAddTaskButton()@Test public void clickingAddTaskButton() throws InterruptedException { // Add test case scenario here WebElement addTaskButton = driver.findElement(By.id("com.example.todoapp:id/fab")); addTaskButton.click(); // quick debug wait for 2 seconds Thread.sleep(2000); WebElement addTaskTitle = driver.findElement(By.id("com.example.todoapp:id/titleEditText")); Assert.assertTrue(addTaskTitle.isDisplayed(), "User is on the Add Task Details Screen"); driver.navigate().back(); Thread.sleep(1000); }addingTaskToDoTheList() TestNext, we have the addingTaskToDoTheList() method, which adds a task to the to-do list. This method clicks the “Add Task” button, enters a title and description for the new task, and then saves it. After saving, it verifies that the new task appears in the task list.Test: addingTaskToDoTheList()@Test public void addingTaskToDoTheList() throws InterruptedException { WebElement addTaskButton, saveButton; WebElement addTaskTitleField, addTaskDescField; // click the Add Task button addTaskButton = driver.findElement(By.id("com.example.todoapp:id/fab")); addTaskButton.click(); // quick debug wait for 2 seconds Thread.sleep(2000); // add title to the task addTaskTitleField = driver.findElement(By.id("com.example.todoapp:id/titleEditText")); addTaskTitleField.click(); addTaskTitleField.sendKeys("Buy Milk"); // add description to the task addTaskDescField = driver.findElement(By.id("com.example.todoapp:id/descriptionEditText")); addTaskDescField.click(); addTaskDescField.sendKeys("Grab 2 Gallons of Milk"); // click the Save button saveButton = driver.findElement(By.id("com.example.todoapp:id/saveButton")); saveButton.click(); // quick debug wait for 2 seconds Thread.sleep(2000); WebElement newTaskAdded = driver.findElement(By.id("com.example.todoapp:id/textView")); Assert.assertEquals(newTaskAdded.getText().toString(), "Buy Milk", "New Task Found"); }deletingTaskFromTheList() TestFinally, we have the deletingTaskFromTheList() method, which tests the deletion of a task from the list. This method locates the delete button and clicks it, then verifies that the task is removed from the task list.Test: deletingTaskFromTheList()@Test public void deletingTaskFromTheList() throws InterruptedException { WebElement deleteButton; // click the Delete button deleteButton = driver.findElement(By.id("com.example.todoapp:id/doneButton")); deleteButton.click(); // quick debug wait for 2 seconds Thread.sleep(2000); Assert.assertTrue(true, "Task is deleted & is removed from the Task List Screen"); }Full ImplementationHere’s the full implementation of the FirstAppiumTestNG file. FirstAppiumTestNG - Full ImplementationFirstAppiumTestNG.classpackage com.test; import io.appium.java_client.android.AndroidDriver; import org.openqa.selenium.By; import org.openqa.selenium.WebElement; import org.openqa.selenium.remote.DesiredCapabilities; import java.io.File; import java.net.MalformedURLException; import java.net.URL; import org.testng.Assert; import org.testng.annotations.AfterClass; import org.testng.annotations.BeforeClass; import org.testng.annotations.Test; public class FirstAppiumTestNG { public static AndroidDriver driver; @BeforeClass public void setUp() throws MalformedURLException { File app = new File("src/test/resources/app/app-debug.apk"); // Set the desired capabilities for your test DesiredCapabilities caps = new DesiredCapabilities(); caps.setCapability("deviceName", "emulator-5554"); caps.setCapability("platformName", "android"); caps.setCapability("app",app.getAbsolutePath()); // Initialize the Appium driver driver = new AndroidDriver (new URL("http://127.0.0.1:4273/wd/hub"), caps); } @Test public void clickingAddTaskButton() throws InterruptedException { // Add test case scenario here WebElement addTaskButton = driver.findElement(By.id("com.example.todoapp:id/fab")); addTaskButton.click(); // quick debug wait for 2 seconds Thread.sleep(2000); WebElement addTaskTitle = driver.findElement(By.id("com.example.todoapp:id/titleEditText")); Assert.assertTrue(addTaskTitle.isDisplayed(), "User is on the Add Task Details Screen"); driver.navigate().back(); Thread.sleep(1000); } @Test public void addingTaskToDoTheList() throws InterruptedException { WebElement addTaskButton,saveButton; WebElement addTaskTitleField,addTaskDescField; // click the Add Task button addTaskButton = driver.findElement(By.id("com.example.todoapp:id/fab")); addTaskButton.click(); // quick debug wait for 2 seconds Thread.sleep(2000); // add title to the task addTaskTitleField = driver.findElement(By.id("com.example.todoapp:id/titleEditText")); addTaskTitleField.click(); addTaskTitleField.sendKeys("Buy Milk"); // add description to the task addTaskDescField = driver.findElement(By.id("com.example.todoapp:id/descriptionEditText")); addTaskDescField.click(); addTaskDescField.sendKeys("Grab 2 Gallons of Milk"); // click the Save button saveButton = driver.findElement(By.id("com.example.todoapp:id/saveButton")); saveButton.click(); // quick debug wait for 2 seconds Thread.sleep(2000); WebElement newTaskAdded = driver.findElement(By.id("com.example.todoapp:id/textView")); Assert.assertEquals(newTaskAdded.getText().toString(), "Buy Milk", "New Task Found"); } @Test public void deletingTaskFromTheList() throws InterruptedException { WebElement deleteButton; // click the Delete button deleteButton = driver.findElement(By.id("com.example.todoapp:id/doneButton")); deleteButton.click(); // quick debug wait for 2 seconds Thread.sleep(2000); Assert.assertTrue(true, "Task is deleted & is removed from the Task List Screen"); } @AfterClass public void tearDown() { if (driver != null) { // Close the driver session driver.quit(); } } }Running Test: TestNG XML File SetupNow that we’re ready to run our test, let’s create a new testng.xml file in the root of our project. In this new file, we’ll add the XML code below to enable running our FirstAppiumTestNG class.TestNG Suite Config (testng.xml)<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd"> <suite name="My First Appium TestNG Test"> <test name="TODO App Automation Testing"> <classes> <class name="com.test.FirstAppiumTestNG"/> </classes> </test> <!-- Test --> </suite> <!-- Suite --> Create A New TestNG File Naming The File testng.xml Pasting The XML Script In The New Testng.xml FileTo properly run our TestNG XML file, we need to configure the pom.xml file accordingly. Start by opening your pom.xml file and locating the Maven Surefire Plugin section. Within this section, you’ll need to add the TestNG configuration. Specifically, scroll down to where you see the <version> tag within the Maven Surefire Plugin and insert the following configuration just below it:TestNG Suite Setup (pom.xml)<configuration> <suiteXmlFiles> <suiteXmlFile>testng.xml</suiteXmlFile> </suiteXmlFiles> <testFailureIgnore>false</testFailureIgnore> </configuration> Pasting TestNG XML ConfigurationThis snippet tells Maven to use the testng.xml file to determine which tests to run. The <testFailureIgnore> tag is set to false, ensuring that the build will fail if any test fails, which is often the desired behavior in a continuous integration environment.Once you’ve added this configuration, make sure to save your pom.xml file. With these changes in place, your project is now ready to run with the specified TestNG configuration. Let's open the Terminal in Eclipse so we can execute the Maven command. Type or copy the command mvn test -DsuiteXmlFile=testng.xml into the Terminal. Press Enter to execute. The script should begin running the three scenarios we created earlier. As the tests execute, you should see passing logs appear in the console, indicating successful execution. Pasting Maven Command To Run TestNG Successful Test Results After Running CommandRunning Test: TestNG PluginAlternatively, if you have the TestNG plugin installed on your IDE, you can simply right-click on the test file and choose Run As TestNG. This method provides a quick and easy way to execute your tests without the need to manually configure the XML file. class. Running Test File Using 'Run As TestNG'Running FirstAppiumTestNG ScriptAlright, let’s sit back and enjoy watching the results. In the video below, you’ll see the script in action as it runs via the mvn command. The test executes all three scenarios and they pass successfully! It’s always a great feeling when everything works perfectly, isn’t it? Yay! GIF: Script Is Running TestNG Results Pane TestNG HTML Web ResultsConclusionOrganizing multiple test scenarios in Appium using TestNG is a critical step in building a robust test automation strategy. With TestNG, we can group our test cases logically, execute them in a specific order, and generate detailed reports. This structured approach not only saves time but also minimizes errors, making our testing process more reliable and efficient. Stay tuned for our next topic, where we will delve into Understanding Appium UI Locators. Understanding Appium UI Locator Strategies In this guide, we will delve into Appium UI Locator Strategies. Understanding how to efficiently locate elements is crucial for creating robust and maintainable automated tests. This guide is designed to be comprehensive and accessible for both beginners and advanced users. By the end of this guide, you’ll be proficient in various locator strategies in Appium, using Java as our code language.Introduction to LocatorsLocators are used to find UI elements on the mobile application. Appium supports various locator strategies: ID - is a unique identifier for elements. It is one of the most reliable and fastest ways to locate elements. Name - is another attribute that can be used, although it's less common and sometimes deprecated. Class Name - locates elements by their class attribute. It can return multiple elements, so it's often used with other strategies. XPath - is a powerful and flexible locator strategy but can be slower and more brittle. It's often used when other locators are not available. iOS Predicate String (iOS) - iOS Predicate String is used for complex queries on iOS. iOS Class Chain (iOS) - iOS Class Chain is another iOS-specific strategy that allows chaining class names and attributes.Using ID Using an id is one of the most efficient ways to identify and capture elements in Appium, provided that this option is available in our inspector. The id attribute serves as a unique identifier for elements within the DOM, allowing for precise and reliable element selection. This method is particularly advantageous because IDs are designed to be unique within a given page, thereby reducing the risk of selecting the wrong element.By.idWebElement taskButton = driver.findElement(By.id("add-task-button"));Using Name By using the name attribute, you ensure your code remains clear and intuitive. This method not only enhances readability but also reduces the risk of errors that can occur with more complex locators. It’s a straightforward way to improve your Appium testing strategy, making it easier to manage and scale your automated tests. Adopting this practice can lead to more robust and reliable test scripts, ultimately contributing to a more efficient development cycle.By.nameWebElement taskButton = driver.findElement(By.name("add-task-button"));Using XPath When using xpath to identify an element in Appium, you can target specific attributes or hierarchical relationships within the UI structure. For example, you might want to locate a button based on its ID, class, or even its position relative to other elements. This flexibility is one of the key advantages of using xpath over other locating strategies.By.xpathWebElement taskButton = driver.findElement(By.xpath("//android.widget.Button[@content-desc='SIGN IN']"));Using Class Name You can capture and interact with an element by specifying its className. This method is particularly useful when elements share common characteristics or belong to the same class.By.classNameWebElement taskButton = driver.findElement(By.className("android.widget.Button"));[IOS] iOS Predicate StringThis technique offers a precise way to locate elements based on specific attributes. The iOS Predicate String is a powerful tool that leverages the NSPredicate class from Apple’s iOS development environment, allowing developers to create complex queries for UI elements.[IOS] iOS Class Chain This approach leverages the class chain strategy, providing a powerful alternative to traditional locator strategies. By utilizing iOSClassChain, developers can efficiently target elements based on their hierarchical structure, enhancing the precision of their UI automation tests.By.iOSClassChainWebElement taskButton = driver.findElement(By.iOSClassChain("**/XCUIElementTypeButton[`label == 'Task'`]"));ConclusionIn this guide, we explored various Appium UI locator strategies using Java. By mastering these locators, you can write efficient and reliable automated tests for your mobile applications. Remember to prioritize IDs and Accessibility IDs for their reliability and speed, and use XPath judiciously. Stay tuned for our next topic, where we will dive into Advanced Automating Gestures in Appium. Automating Gesture Actions in Appium In the previous guide, we learned about Appium UI Locator Strategies. Now, let’s take it a step further by automating gesture actions. Gestures such as swipes, scrolls, and taps are essential for comprehensive mobile app testing.Common Gesture ActionsAlright, let’s dive into Gesture Actions in Appium. These actions are essential for simulating complex interactions with your mobile app, mimicking how a real user would engage with it. Whether you need to swipe, pinch, zoom, or perform a drag-and-drop action, Appium’s gesture commands have you covered. These gestures are critical for testing user interfaces that rely heavily on touch interactions, ensuring your app behaves as expected in the hands of actual users.Create Gestures Util ClassLet’s dive right in and enhance our Appium project by adding a new class to handle gesture methods efficiently. To begin, we’ll create a new class called GesturesUtil which will serve as a repository for various gesture methods. This step is essential to keep our code organized and maintainable. First, navigate to your project directory and create a new package namedcom.helpers. This package will be the home for our GesturesUtilclass. Organizing your code into packages not only improves readability but also aligns with best practices in software development, making your project more modular and easier to manage.Import DependenciesIn the com.helpers package, create the GesturesUtil class. This class will encapsulate all the gesture methods you need for your Appium tests, such as swipe, tap, and scroll. To get started, the first step is importing the necessary dependencies. In your project, add the following imports:GesturesUtil.classimport io.appium.java_client.AppiumDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.interactions.PointerInput; import org.openqa.selenium.interactions.Sequence; import java.time.Duration; import java.util.Arrays; import java.util.Collections;With these imports in place, you can now proceed to define your gesture methods without encountering any compilation issues. This setup ensures that your code is well-structured and ready to handle a variety of automated testing scenarios, making your Appium testing framework robust and efficient.Simulating Tap or Long Press A tap is simply a quick touch on the screen, often used for selecting items, while a long press involves holding down on an element for a longer duration. This is typically used for actions like bringing up a context menu or initiating a special function. Appium’s capabilities allow you to simulate both, ensuring that these interactions are tested thoroughly.Gesture: tapElementpublic void tapElement(WebElement element) { PointerInput finger = new PointerInput(PointerInput.Kind.TOUCH, "finger"); Sequence tap = new Sequence(finger, 1) .addAction(finger.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), element.getLocation().x + element.getSize().width / 2, element.getLocation().y + element.getSize().height / 2)) .addAction(finger.createPointerDown(PointerInput.MouseButton.LEFT.asArg())) .addAction(finger.createPointerUp(PointerInput.MouseButton.LEFT.asArg())); driver.perform(Collections.singletonList(tap)); }TapThe tapElement method simulates a tap on a web element by: Creating a touch input named finger. Creating a sequence of actions that: - Moves the touch pointer to the center of the specified element. - Presses down on the element. - Releases the press. Perform the sequence of actions using the driver.Gesture: Long Presspublic void longPressElement(WebElement element, Duration duration) { PointerInput finger = new PointerInput(PointerInput.Kind.TOUCH, "finger"); Sequence longPress = new Sequence(finger, 1) .addAction(finger.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), element.getLocation().x + element.getSize().width / 2, element.getLocation().y + element.getSize().height / 2)) .addAction(finger.createPointerDown(PointerInput.MouseButton.LEFT.asArg())) .addAction(finger.createPointerMove(duration, PointerInput.Origin.viewport(), element.getLocation().x,element.getLocation().y)) .addAction(finger.createPointerUp(PointerInput.MouseButton.LEFT.asArg())); driver.perform(Collections.singletonList(longPress)); }Long PressThe longPressElement method simulates a long press on a mobile or web element by: Moving the virtual finger to the center of the element. Pressing down on the element. Holding the press for a specified duration. Releasing the press.Simulating Swipe GesturesIn Appium, swiping is straightforward but powerful, allowing you to simulate the user’s finger moving across the screen.To implement a swipe, you define the start and end coordinates, which tells Appium where the swipe should begin and end. By fine-tuning these coordinates, you can create swipes that mimic natural user behavior, ensuring your test cases are as realistic as possible.Gesture: Swipepublic void swipe(int startX, int startY, int endX, int endY, Duration duration) { PointerInput finger = new PointerInput(PointerInput.Kind.TOUCH, "finger"); Sequence swipe = new Sequence(finger, 1) .addAction(finger.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), startX, startY)) .addAction(finger.createPointerDown(PointerInput.MouseButton.LEFT.asArg())) .addAction(finger.createPointerMove(duration, PointerInput.Origin.viewport(), endX, endY)) .addAction(finger.createPointerUp(PointerInput.MouseButton.LEFT.asArg())); driver.perform(Collections.singletonList(swipe)); }SwipeThe swipe function simulates a swipe gesture on a touch screen. First, it moves the touch pointer from a starting point (startX, startY) Next it moves to the ending point (endX, endY) over a given duration. The process involves moving the pointer to the start position, touching down, moving to the end position, and then lifting up All of these actions are coordinated through a sequence of actions performed by the driver.Simulating a Zoom InNext we have pinch and zoom gestures, which are indispensable for applications that involve maps, images, or any form of visual content that users might need to zoom in and out of.Gesture: Zoom Inpublic void zoomIn(WebElement element) { int centerX = element.getLocation().getX() + element.getSize().getWidth() / 2; int centerY = element.getLocation().getY() + element.getSize().getHeight() / 2; int endX1 = centerX - 100; int endY1 = centerY - 100; int endX2 = centerX + 100; int endY2 = centerY + 100; PointerInput finger1 = new PointerInput(PointerInput.Kind.TOUCH, "finger1"); Sequence pinch1 = new Sequence(finger1, 1) .addAction(finger1.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), centerX, centerY)) .addAction(finger1.createPointerDown(PointerInput.MouseButton.LEFT.asArg())) .addAction(finger1.createPointerMove(Duration.ofMillis(600), PointerInput.Origin.viewport(), endX1, endY1)) .addAction(finger1.createPointerUp(PointerInput.MouseButton.LEFT.asArg())); PointerInput finger2 = new PointerInput(PointerInput.Kind.TOUCH, "finger2"); Sequence pinch2 = new Sequence(finger2, 1) .addAction(finger2.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), centerX, centerY)) .addAction(finger2.createPointerDown(PointerInput.MouseButton.LEFT.asArg())) .addAction(finger2.createPointerMove(Duration.ofMillis(600), PointerInput.Origin.viewport(), endX2, endY2)) .addAction(finger2.createPointerUp(PointerInput.MouseButton.LEFT.asArg())); driver.perform(Arrays.asList(pinch1, pinch2)); }PinchingPinching involves bringing two fingers together on the screen, while zooming involves spreading them apart. Appium handles these multi-touch gestures by specifying the touch points and their movements, giving you precise control over the interactions. Calculate the center coordinates (centerX, centerY)of the element. Define end coordinates for the pinch gesture (endX1, endY1, endX2, endY2). Create the first finger input sequence pinch1to: - Move to the center of the element. - Press down. - Move to the end coordinates over 600 ms. - Lift up the finger. Create the seond finger input sequence pinch2 to: - Move to the center of the element. - Press down. - Move to the end coordinates over 600 ms. - Lift up the finger. Execute both sequences simultaneously to perform the pinch gesture.Simulating a Zoom OutPerform a zoom out gesture by reversing the pinch gesture:Gesture: Zoom Outpublic void zoomOut(WebElement element) { int centerX = element.getLocation().getX() + element.getSize().getWidth() / 2; int centerY = element.getLocation().getY() + element.getSize().getHeight() / 2; int startX1 = centerX - 100; int startY1 = centerY - 100; int startX2 = centerX + 100; int startY2 = centerY + 100; PointerInput finger1 = new PointerInput(PointerInput.Kind.TOUCH, "finger1"); Sequence pinchIn1 = new Sequence(finger1, 1) .addAction(finger1.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), startX1, startY1)) .addAction(finger1.createPointerDown(PointerInput.MouseButton.LEFT.asArg())) .addAction(finger1.createPointerMove(Duration.ofMillis(600), PointerInput.Origin.viewport(), centerX, centerY)) .addAction(finger1.createPointerUp(PointerInput.MouseButton.LEFT.asArg())); PointerInput finger2 = new PointerInput(PointerInput.Kind.TOUCH, "finger2"); Sequence pinchIn2 = new Sequence(finger2, 1) .addAction(finger2.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), startX2, startY2)) .addAction(finger2.createPointerDown(PointerInput.MouseButton.LEFT.asArg())) .addAction(finger2.createPointerMove(Duration.ofMillis(600), PointerInput.Origin.viewport(), centerX, centerY)) .addAction(finger2.createPointerUp(PointerInput.MouseButton.LEFT.asArg())); driver.perform(Arrays.asList(pinchIn1, pinchIn2)); }ZoomingPinching involves bringing two fingers together on the screen, while zooming involves spreading them apart. Appium handles these multi-touch gestures by specifying the touch points and their movements, giving you precise control over the interactions. Calculate the center coordinates of the element. Define starting points for two touch actions, positioned diagonally around the center. Create a touch action sequence for the first finger, moving from the starting point to the center. Create a touch action sequence for the second finger, moving from the starting point to the center. Execute both sequences simultaneously to perform the pinch-in gesture.ConclusionIncorporating gesture actions into your Appium tests enhances functionality and verifies a seamless user experience. By simulating real user gestures, you can uncover issues that traditional testing may miss, leading to a more robust and user-friendly app.Whether you’re testing a simple or complex app, mastering these gestures will improve your testing outcomes. In the next guide, you’ll learn about Capturing Screenshots and Logs in Appium. Capturing Screenshots and Logs In Appium Capturing screenshots and logs during your tests is crucial for diagnosing issues, verifying UI elements, and ensuring your app behaves as expected. Screenshots provide visual evidence, while logs offer detailed information about the app’s behavior, network requests, errors, and more.Create New Utils ClassLet’s begin by creating a new Utils class, which will be instrumental in managing your screenshot captures and logging methods. To start, navigate to your project and create a new class within the com.helpers package, or alternatively, any directory that suits your organizational preferences. Creating A New Utils ClassUtils.classpackage com.helpers; import org.openqa.selenium.OutputType; import org.openqa.selenium.TakesScreenshot; import org.openqa.selenium.WebDriver; import org.openqa.selenium.logging.LogEntry; import org.openqa.selenium.io.FileHandler; import org.openqa.selenium.logging.LogEntries; import org.openqa.selenium.logging.LogType;Capturing ScreenshotsTo capture screenshots in Appium using Java, you can use the getScreenshotAs method. Utils.classpublic class Utils { public static void captureScreenshot(WebDriver driver, String fileName) { File srcFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE); try { FileHandler.copy(srcFile, new File("./target/screenshots/" + fileName + ".png")); } catch (IOException e) { e.printStackTrace(); } } It’s important to organize your project structure effectively. To achieve this, we’ll create a dedicated /screenshots directory within the target folder of your project. This organization ensures that all screenshots are stored in a centralized location, making them easy to locate and manage. Creating A New Screenshots Directory For instance, when you capture a screenshot during the automation process, you can save it in this newly created directory. To maintain clarity and avoid confusion, it's essential to give each screenshot file a descriptive name. In this particular example, we will name the screenshot file add_new_task_screen.In this particular example, we will name the screenshot file add_new_task_screen. This naming convention not only helps in identifying the context of the screenshot quickly but also enhances the overall readability and maintainability of your test reports.Call this method in your test script where you want to capture the screenshot: Test: clickingAddTaskButton()@Test public void clickingAddTaskButton() throws InterruptedException { // Add test case scenario here WebElement addTaskButton = driver.findElement(By.id("com.example.todoapp:id/fab")); addTaskButton.click(); // quick debug wait for 2 seconds Thread.sleep(2000); WebElement addTaskTitle = driver.findElement(By.id("com.example.todoapp:id/titleEditText")); Assert.assertTrue(addTaskTitle.isDisplayed(), "User is on the Add Task Details Screen"); Utils.captureScreenshot(driver, "add_new_task_screen"); driver.navigate().back(); Thread.sleep(1000); }When executing your script in Appium, the captured screenshot is stored in the /target/screenshot/ directory. To view the newly captured screenshot, you will need to refresh your project. Once refreshed, the file named add_new_task_screen will appear in the screenshots directory. This step is crucial for verifying that your automation scripts are correctly capturing the visual output you expect. GIF: Reviewing Screenshot Image After Executing TestCapturing LogsTo capture logs in Appium using Java, you can use the getLog method. Here’s how:Test: captureLogs()public static void captureLogs(WebDriver driver) { LogEntries logEntries = driver.manage().logs().get(LogType.BROWSER); for (LogEntry entry : logEntries) { System.out.println(entry.getMessage()); } }Call this method in your test script to capture and print the logs: JavaUtils.captureLogs(driver);Troubleshooting Permission Issues: Ensure your script has write permissions to the directory where screenshots and logs are saved. Driver Compatibility: Make sure the Appium driver versions are compatible with your testing framework and mobile OS. Error Handling: Implement error handling in your scripts to manage exceptions during screenshot or log capture.Best Practices Organize Screenshots: Save screenshots with meaningful names and organize them in folders based on test cases or test runs. Log Levels: Use different log levels (e.g. INFO, DEBUG, ERROR) to filter logs effectively. Automate Log Analysis: Consider automating log analysis to highlight errors or warnings. Periodic Captures: Capture screenshots and logs periodically during long test runs to monitor app behavior over time.ConclusionBy now, you should know how to capture screenshots and logs during your Appium test executions. This knowledge will significantly enhance your ability to debug and report on your tests. Continue honing your skills and exploring more advanced topics in Appium and QA testing. Happy testing!

It’s designed to be simple, easy to understand, and accessible to non-developers. Gherkin acts as the bridge between plain text descriptions of software behaviors and the automation code that validates those behaviors.Feature FilesFeature files are where Gherkin shines. These text files have a .feature extension and contain high-level descriptions of software features or functionalities. They serve as documentation and test scripts simultaneously.ScenariosScenarios are individual test cases written in Gherkin. They describe a specific behavior or test case, typically following a Given-When-Then structure. For example:Scenario: home-screen.featureFeature: Home Screen - Verify Web App Navigation Menu Links Scenario: Click the Login Icon Given the user is on the home screen When the user clicks the "login" icon Then the "Login" screen is displayed 1 Given 2 When 3 Then This keyword sets the stage for the scenario by describing the initial context or preconditions. It establishes the state of the system before the action occurs.This keyword defines the action or event that triggers the scenario. It represents the user's interaction with the system or the event that takes place.This keyword outlines the expected outcome or result after the action is performed. It specifies what should happen as a result of the interaction, allowing for validation of the scenario. Step DefinitionsStep definitions are the automation code that executes the steps in Gherkin scenarios.Step Defintionspublic class HomeStepDefs { public WebDriver driver = Hooks.driver; @Given("the user is on the home screen") public void the_user_is_on_the_home_screen() throws InterruptedException { // logic goes here } @When("the user clicks the {string} icon") public void the_user_clicks_the_icon(String iconName) { // logic goes here } @Then("the {string} screen is displayed") public void the_screen_is_displayed(String screenName) { // logic goes here } @When("the user clicks the {string} link") public void the_user_clicks_the_link(String linkName) { // logic goes here } }Benefits of Cucumber and Gherkin Improved Collaboration: Cucumber and Gherkin facilitate effective communication between technical and non-technical team members, leading to better software understanding. Reusable Steps: Gherkin steps can be reused across multiple scenarios, reducing redundancy and maintenance efforts. Living Documentation: Feature files serve as living documentation that stays up-to-date with your application's behavior. Automation: Cucumber allows you to automate tests based on Gherkin scenarios, making it easier to validate software functionality.ConclusionNow that you have a basic understanding of Cucumber and Gherkin, it’s time to Set Up Cucumber in Your Project. Setting Up Cucumber in Your Project In this guide, we’ll walk you through the essential steps to set up Cucumber in a Java project. Proper setup is crucial for ensuring a smooth workflow for your Behavior-Driven Development (BDD) testing. By following this guide, you’ll be well on your way!Prerequisites Java Development Kit (JDK) installed. Integrated Development Environment (IDE) Eclipse. Maven for dependency management.Create a New Maven ProjectTo embark on your journey with a Cucumber Gherkin project, the first step is to create a new Maven project. If you’re unfamiliar with setting up a Maven project, don’t worry. Our guide here on How To Create A New Maven Project in Eclipse, will walk you through the process step by step.Once your Maven project is successfully set up, the next crucial task is to add the core Maven dependencies required for your Cucumber Gherkin project. Head over to your pom.xml file and these between your dependencies tag. Adding Dependencies To pom.xmlpom.xml<!-- Selenium Java --> <dependency> <groupId>org.seleniumhq.selenium</groupId> <artifactId>selenium-java</artifactId> <version>4.20.0</version> </dependency> <!-- Cucumber Java --> <dependency> <groupId>io.cucumber</groupId> <artifactId>cucumber-java</artifactId> <version>7.11.0</version> </dependency> <!-- Cucumber JUnit --> <dependency> <groupId>io.cucumber</groupId> <artifactId>cucumber-junit</artifactId> <version>7.11.0</version> </dependency> <!-- JUnit 4 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> <!-- Extent Reports Cucumber Adapter --> <dependency> <groupId>tech.grasshopper</groupId> <artifactId>extentreports-cucumber7-adapter</artifactId> <version>1.14.0</version> </dependency> <!-- Extent Reports --> <dependency> <groupId>com.aventstack</groupId> <artifactId>extentreports</artifactId> <version>5.1.1</version> </dependency> <!-- Commons IO --> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.11.0</version> </dependency>Organizing Your Project Structure Now that we have our project created, let’s set up our base folders and directories. To get started, we’ll need to create a few specific folders. In this guide we’ll be incorporating the com.kicksapp package in our project to keep our files organize. Organizing Cucumber Project com/kicksapp/runners - This folder is where our test runner files will be stored. These files are essential for executing our test suites. com/kicksapp/stepdefs - Here, we'll keep our test step definitions. This organization helps in managing the steps involved in our tests, making them easy to locate and modify. src/test/resources/driver - This is the designated folder for our driver files. For this project, we'll be using Chromedriver. Ensuring the driver is in the right place helps in seamless test execution. src/test/resources/features - Most importantly, this folder will store our feature files. Feature files are the cornerstone of our behavior-driven development (BDD) approach, outlining the scenarios and behaviors our application should exhibit. Tip: Naming Your Package DirectoryYou can choose to keep you package as simple as src/test/java/runners or src/test/java/stepdefs. However in this guide We’ll be using the com/kicksapp/… package.Downloading the Cucumber Plugin for EclipseOnce we have these packages and folders set up, the next step is to download the Cucumber plugin for Eclipse. This plugin is essential for integrating Cucumber with Eclipse, providing a robust environment for running and managing our BDD tests.Navigate to the top menu and click on Help . From the dropdown menu, select Eclipse Marketplace… Installing Cucumber Plugin From The Eclipse Marketplace Search for Cucumber: In the Eclipse Marketplace window, use the search bar to type in [direction]"Cucumber"[/direction]. Press Enter to view the search results. Install the Cucumber Plugin: Locate the Cucumber plugin from the list of results. Click the [direction]Install[/direction] button next to the Cucumber plugin entry. Follow the prompts to complete the installation process. Restart Eclipse: Once the installation is finished, you will be prompted to restart Eclipse. Click [direction]Restart Now[/direction] to apply the changes.ConclusionOrganizing your project with these folders ensures a streamlined process where each component of your testing framework is easily accessible. This setup not only enhances productivity but also aligns with best practices in test automation, making it easier to scale and maintain your tests.Now you’re ready to Write Your First Gherkin Feature File. Continue to the next guide to dive into writing Gherkin scenarios. Writing Your First Gherkin Feature File Now that you have Cucumber set up in your project, it’s time to write your first Gherkin feature file. This guide will help you create a feature file and define scenarios using Gherkin syntax.Gherkin feature files are written with the .feature extension and contain a structured language with keywords like Feature, Scenario, Given, When, Then, And, and But. Let’s write a simple feature file for a checking the navigation on the Kicks Web App functionality. Kicks App | Flutter WebCreating a Feature FileFirst, navigate to your project’sfeaturesdirectory. This is where all your feature files will reside. To get started with our scenarios, we need to create a new file. Create a file named home-screen.feature inside the features directory. Creating The Home Screen Feature FilePath: home-screen.featuresrc/test/resources/features/home-screen.featureBy creating the home-screen.feature file, we establish a dedicated space for our home screen scenarios. This approach not only helps in organizing our tests but also makes it easier to locate and update them as needed.Write a Feature Scenario Ensuring a seamless user experience starts with verifying that all navigation links on the home screen function as expected. Below we are going test a few test cases related to the navigation menu.home-screen.feature# Author: J Richard | Mastering QA Feature: Home Screen - Verify Web App Navigation Menu Links Scenario: Click the Login Icon Given the user is on the home screen When the user clicks the "login" icon Then the "Login" screen is displayed Scenario: Click the Products link Given the user is on the home screen When the user clicks the "Products" link Then the "Products" screen is displayed Home Screen Feature File ScenariosUnderstanding Gherkin Syntax Feature: Provides a detailed overview of the feature being tested, outlining its purpose and functionality. Scenario: Specifies a particular test case for the feature, illustrating a unique situation to validate its performance. Given: Establishes the initial conditions and context necessary for the test to proceed, ensuring a proper setup. When: Captures the specific actions taken by the user during the test, detailing the interactions that trigger the functionality. Then: Articulates the expected results of the test, defining the criteria for success and the desired behavior of the feature. Given the user is on the home screenThis step sets the initial context. It assumes the user has already landed on the home screen of the web application. When the user clicks the "login" icon This action step simulates the user clicking on the login icon, which is expected to take them to the login screen. Then the "Login" screen is displayedThe final step verifies the outcome, ensuring that clicking the login icon indeed navigates the user to the login screen. Click the Products Link TestThe second scenario is pretty much similar but in this case we will be clicking the products link and verifying that we landed there successfully.ConclusionYou’ve written your first Gherkin feature file. Next, you’ll learn how about Scenario Outlines and Examples. Continue to the next guide to explore step definitions. Scenario Outlines and Examples In this guide, you’ll learn how to use scenario outlines and examples to write more dynamic and data-driven tests. This allows you to test multiple cases with different inputs and expected outcomes efficiently.What is a Scenario Outline? A Scenario Outline is a template for a scenario that can be run multiple times with different sets of data. It is useful when you want to test the same scenario with different inputs and expected outcomes. This helps in reducing redundancy and improving the readability and maintainability of your test suite.Syntax of Scenario OutlineThe syntax of a Scenario Outline in Gherkin is as follows:GherkinScenario Outline: Title of the scenario Given some precondition When some action is performed Then some expected outcome should happen Examples: | parameter1 | parameter2 | | value1 | value2 | | value3 | value4 | Scenario Outline: This keyword establishes a scenario template that allows for the reuse of the same test steps with varying data inputs, streamlining the testing process. Examples: This section specifies the various sets of data that will be used to fill in the placeholders defined in the Scenario Outline, enabling comprehensive testing of multiple scenarios efficiently.Using Examples in Scenario Outline The Examples section contains a table where each row represents a different set of values to be used in the scenario. The values from the table are substituted into the scenario outline, and the scenario is run once for each row. Cucumber Scenario Outline ExampleConsider a scenario where we want to test the products filter functionality of the Kicks website with different filters and verifying the item counts. This involves simulating user actions on the website to ensure that the filters for products work as expected.GherkinFeature: Products Page Filters & Stock Count Scenario Outline: User clicks product filter, choose a gender option and verify item count Given the user is on the products screen When the user clicks "<filter>" filter option And the user clicks the "<gender>" gender option And the user clicks a "<size>" shoe Then the first sneaker option is "<first_sneaker>" And the result is now "<item_count>" Examples: | filter | gender | size | first_sneaker | item_count | | Most popular | Male | 10.5 | Adidas Converse | 7 items | | Lowest price | Female | 6 | New Balance Streetwear | 13 items | | Highest price | Male | 9.5 | Jordan Orginal | 9 items | | Newest | Female | 7 | Nike Air Max 360 | 14 items |This feature focuses on verifying that the product filters on the Kicks website are working correctly. It includes tests for various filters such as Most popular, Lowest price, Highest price, and Newest to ensure they return the correct item count. Given the user is on the products screenThis step sets the initial condition that the user is on the products page of the website. When the user clicks "<filter>" filter optionThis action simulates the user clicking on a specific filter option, such as Most popular or Lowest price. And the user clicks the "<gender>" gender optionThis action simulates the user selecting a gender filter, such as Male or Female. And the user clicks a "<size>" shoeThis action simulates the user selecting a shoe size, such as 10.5 or 6. Then the first sneaker option is "<first_sneaker>"This step verifies that the first sneaker displayed matches the expected sneaker for the given filter. And the result is now "<item_count>"This step verifies that the total number of items displayed matches the expected item count.ConclusionGherkin Scenario Outlines are essential for enhancing clarity and efficiency in your behavior-driven development (BDD) process. They allow for reusable scenarios with varying inputs, simplifying test case creation and promoting collaboration among team members. In the next guide, you’ll learn about Implementing Step Definitions, where we’ll connect your Gherkin scenarios to executable code. Implementing Step Definitions Now is the time to create and implement our Step Definition Class in Cucumber. This critical step will ensure our test automation framework is robust and efficient. In this guide, we will walk you through the process of setting up your Step Definition Class, specifically focusing on creating a file to store your HomeStepDefs file within your project.Setting Up Your Step Definition ClassTo begin, navigate to the appropriate location in your project directory where you want to store your Step Definition files. It’s essential to keep your project well-organized, making it easier to maintain and scale as needed. In this case we’ll be storing our files in this location – src/test/java/com/kicksapp/stepDefs Cucumber Step Definitions Directory IDE: Launch Eclipse and open your project to get started on your Gherkin test definitions. Directory: Navigate to the src/test/java/com/kicksapp/stepDefs/ directory, where your step definitions will be organized. Create a New File: In the stepDefs directory, right-click and choose [direction]New File[/direction] to create a new file named HomeStepDefs.java, which will house your Gherkin step definitions for the Home feature.HomeStepDefssrc/test/java/kicksapp/stepDefs/HomeStepDefs.javaConvert Project to A Cucumber ProjectRight-click on your project and select Configure Convert to Cucumber Project . This set is necessary so we can generate our gherkin snippets. Converting Project To A Cucumber ProjectGenerate Gherkin Method SnippetsTo generate the necessary Gherkin method snippets, run the home-screen.feature file: Run Feature File: Right-click on the home-screen.feature file and select [direction] Run As > Cucumber Feature[/direction]. Review Snippets: Eclipse will execute the feature file, and if any step definitions are missing, it will generate method snippets for you. Copy these snippets into your HomeStepDefs.java class. Gherkin Generated Sample SnippetsGherkin Method Snippets@Given("the user is on the home screen") public void the_user_is_on_the_home_screen() { // Write code here that turns the phrase above into concrete actions throw new io.cucumber.java.PendingException(); } @When("the user clicks the {string} icon") public void the_user_clicks_the_icon(String string) { // Write code here that turns the phrase above into concrete actions throw new io.cucumber.java.PendingException(); } @Then("the {string} screen is displayed") public void the_screen_is_displayed(String string) { // Write code here that turns the phrase above into concrete actions throw new io.cucumber.java.PendingException(); } @When("the user clicks the {string} link") public void the_user_clicks_the_link(String string) { // Write code here that turns the phrase above into concrete actions throw new io.cucumber.java.PendingException(); }Now that we have our snippets, it’s time to add the necessary logic to each method to complete our HomeStepDefs class. This step is crucial as it bridges the gap between our feature files written in Gherkin and the actual automation code that interacts with our web application.In the HomeStepDefs class, we initialize a WebDriver instance through the Hooks class, ensuring a consistent browser session. The testUrl variable holds the URL of our web application, setting the stage for user interaction scenarios.HomeStepDefs – WebDriverpublic class HomeStepDefs { public WebDriver driver = Hooks.driver; private final String testUrl = "https://jahmalrichard.github.io/kicks-flutter-web-app/";Navigating to the Home ScreenThe first step is to navigate the user to the home screen. Using the @Given annotation, we define the method the_user_is_on_the_home_screen. This method directs the browser to the specified URL and pauses for 2 seconds to ensure the page is fully loaded. Kicks App | Home Screen@Given@Given("the user is on the home screen") public void the_user_is_on_the_home_screen() throws InterruptedException { driver.get(testUrl); Utils.wait(2); }Interacting with IconsNext, we manage user interactions with icons on the home screen. The @When annotation is used to define the method the_user_clicks_the_icon. This method receives an icon name as a parameter, locates the corresponding icon using a CSS selector, and performs a click action. Find & Click The Login Icon@When@When("the user clicks the {string} icon") public void the_user_clicks_the_icon(String iconName) { try { switch(iconName.toLowerCase()) { case "login": { WebElement loginIcon = driver.findElement( By.cssSelector("flt-semantics[aria-label=\"login-icon\"]")); loginIcon.click(); Utils.wait(2); break; } default: System.err.println("The icon called '" + iconName + "' was not found. Try again."); } } catch (Exception e) { e.printStackTrace(); } }Verifying Screen DisplaysAfter interacting with icons, it’s essential to verify that the correct screen is displayed. The @Then annotation defines the method the_screen_is_displayed, which checks for the presence of the Sign In button on the login screen to confirm successful navigation. Verify That The Sign In Button Exist Verifying That The Product Page Is Displayed@Then@Then("the {string} screen is displayed") public void the_screen_is_displayed(String screenName) { try { switch(screenName.toLowerCase()) { case "login": { WebElement loginSignInButton = driver.findElement(By.cssSelector("flt-semantics[aria-label=\"Sign In\"]")); assert loginSignInButton.isDisplayed(); Utils.wait(2); break; } case "products": { WebElement filterMostPopular = driver.findElement(By.cssSelector("flt-semantics[aria-label=\"Most popular\"]")); assert filterMostPopular.isDisplayed(); Utils.wait(2); break; } default: System.err.println("The screen named '" + screenName + "' was not found. Try again."); } } catch (Exception e) { e.printStackTrace(); } }Navigating via LinksLastly, we enable users to click on various links within the application. The @When annotation is used again to define the method the_user_clicks_the_link, which handles click actions for specified links. Tip: Navigating LinksThis method is related to the second scenario, where we click on the Products link and verify that we’re on he Products screen. User Clicks The Products Link@When@When("the user clicks the {string} link") public void the_user_clicks_the_link(String linkName) { try { switch(linkName.toLowerCase()) { case "products": { WebElement productsNavLink = driver.findElement( By.cssSelector("flt-semantics[aria-label=\"Products\"]")); productsNavLink.click(); Utils.wait(2); break; } default: System.err.println("The link named '" + linkName + "' was not found. Try again."); } } catch (Exception e) { e.printStackTrace(); } } } Tip: HomeStepDefsBy integrating these methods into our HomeStepDefs class, each method is crafted to handle specific interactions and verifications, making our tests both comprehensive and easy to understand.ConclusionNow that we have a solid grasp of creating and managing step definitions, it’s time to elevate our Cucumber skills further. In next guide, we’ll delve into Understanding Cucumber Tags, a powerful feature that can enhance the flexibility and efficiency of your testing framework. Understanding Cucumber Tags In this guide, you’ll learn how to use Cucumber tags and hooks to organize and manage your tests efficiently. Tags allow you to categorize your scenarios, and hooks provide a way to run code before or after scenarios.Tags in CucumberTags are a way to organize and control the execution of your tests. They allow you to group scenarios, features, or even specific steps, making it easier to manage large test suites. Tags are prefixed with @ and placed above the relevant Gherkin keyword. Single TagA single tag, such as @smoketest or @ignore, is used to label a specific test scenario. For instance, @smoketest indicates a basic test run to check the essential functionality, while @ignore is used to exclude certain tests from execution.Single Tag: @smoketest | @ignore@smoketest Scenario: Click the Login Icon Given the user is on the home screen When the user clicks the "login" icon Then the "Login" screen is displayed @ignore Scenario: Click the Products link Given the user is on the home screen When the user clicks the "Products" link Then the "Products" screen is displayedMultiple TagsMultiple tags, like @smoketest @critical, combine multiple categories, providing a more granular control over which tests to run. This combination might be used to run tests that are both part of the smoke test suite and critical for the application, ensuring that key functionalities are validated promptly.Multiple Tags: @smoketest @critical@smoketest @critical Scenario: Click the Login Icon Given the user is on the home screen When the user clicks the "login" icon Then the "Login" screen is displayedCreating a Test RunnerCreate a test runner class in the src/test/java/com/kicksapp/runners directory. We’re going to name this class HomeScreenRunner. Creating Home Screen Runner FileRunning Tests with TagsTo run tests with specific tags, use the @RunWithand @CucumberOptions annotations in your test runner class.The @CucumberOptions annotation is where you configure various aspects of your Cucumber tests. Here’s a breakdown of the options used in the snippet: Cucumber Runner File With OptionsHomeScreenRunner.classimport org.junit.runner.RunWith; import io.cucumber.junit.Cucumber; import io.cucumber.junit.CucumberOptions; @RunWith(Cucumber.class) @CucumberOptions( features = "src/test/resources/features/home-screen.feature", glue = "com.kicksapp.stepdefs", tags = "@smoketest", plugin = {"pretty", "html:target/cucumber-reports.html"}, monochrome = true ) public class HomeScreenRunner { }features = "src/test/resources/features/home-screen.feature": This specifies the path to the feature files. Feature files contain scenarios written in Gherkin language, which Cucumber executes.glue = "com.kicksapp.stepdefs": This option specifies the package where step definition methods are located. Step definitions are the actual code implementations of the steps described in the feature files.tags = "@smoketest": Tags are used to filter which tests to run. In this case, only the scenarios tagged with @smoketest will be executed.plugin = {"pretty", "html:target/cucumber-reports.html"}: This specifies the reporting plugins to use. The html plugin generates a simple html test report.monochrome = true: This option makes the console output more readable by removing unnecessary characters and colors.Tag ExpressionsCucumber supports tag expressions to combine multiple tags using logical operators: AND The AND operator in Cucumber tag expressions is used to run scenarios that are tagged with multiple tags simultaneously. For instance, consider the tags @login and @critical. By using the expression @login and @critical, Cucumber will execute only those scenarios that are tagged with both @login and @critical. This is particularly useful when you need to focus on tests that are both essential and pertain to specific functionalities.Tags: AND@CucumberOptions( features = "src/test/resources/features/home-screen.feature", glue = "com.kicksapp.stepdefs", tags = "@login and @critical", plugin = {"pretty", "html:target/cucumber-reports.html"}, monochrome = true ) OR The OR operator broadens the scope by running scenarios that match any of the specified tags. For example, using @moketest or @critical will run all scenarios tagged with either @smoketest or @critical. This approach is beneficial when you want to cover a broader range of tests without being too restrictive, ensuring that all relevant functionalities are tested.Tags: OR@CucumberOptions( features = "src/test/resources/features/home-screen.feature", glue = "com.kicksapp.stepdefs", tags = "@smoketest or @critcal", plugin = {"pretty", "html:target/cucumber-reports.html"}, monochrome = true ) NOT The NOT operator is employed to exclude specific tags from the test run. For example, the expression not @ignore will execute all scenarios except those tagged with @ignore. This is especially useful for excluding tests that are either known to fail, are under development, or are not currently relevant to the test cycle.Tags: NOT@CucumberOptions( features = "src/test/resources/features/home-screen.feature", glue = "com.kicksapp.stepdefs", tags = "@smoketest and not @ignore", plugin = {"pretty", "html:target/cucumber-reports.html"}, monochrome = true )ConclusionYou’ve mastered the art of using tags. Tags allow you to categorize your scenarios, making it easier to run specific tests based on your needs. Whether you’re focusing on a particular feature or running regression tests, tags streamline the process, saving you valuable time.Now that you are comfortable with tags, it’s time to start Understanding Cucumber Hooks. Understanding Cucumber Hooks In this guide, you’ll learn how to use Cucumber hooks to streamline your testing process and make your scenarios more efficient. Cucumber hooks are blocks of code that run at various points in the Cucumber test cycle, allowing you to set up and tear down the test environment, manipulate data, and configure test settings dynamically. By mastering hooks, you can enhance your test suite’s maintainability and readability, ensuring that your tests run smoothly and reliably.Hooks in CucumberHooks are special blocks of code that run at specific points in the test execution lifecycle. They allow you to set up preconditions and postconditions for your tests. In Cucumber, hooks are defined using the @Before and @After annotations.Types of HooksBefore HookThe @Before hook, as the name suggests, runs before each scenario. This means that any code you include in a @Before hook will execute before your test case starts. This is essential for preparing the test environment, ensuring that each test runs in a clean and consistent state. For instance, you might want to launch a browser, navigate to a specific URL, or initialize test data.@Before Hookpublic class Hooks { public static WebDriver driver; @Before public void setup() { System.setProperty("webdriver.chrome.driver", "src/test/resources/driver/chromedriver"); driver = new ChromeDriver(); driver.manage().timeouts().implicitlyWait(Duration.ofSeconds(10)); driver.manage().window().maximize(); }After HookAmong the different types of hooks, the @After hook plays a crucial role in ensuring your test scenarios are executed smoothly and efficiently. Specifically, the @After hook runs after each scenario, providing a perfect opportunity to perform cleanup tasks, release resources, or log information that helps in debugging and analysis.@After Hook@After public void tearDown() { if (driver != null) { driver.quit(); driver = null; }BeforeStepThe @BeforeStep hook, as its name suggests, runs before each individual step in your test scenarios. This hook can be particularly useful for setting up preconditions or performing repetitive tasks that need to be executed before every step.@BeforeStep Hook@BeforeStep public void beforeStep(Scenario scenario) { System.out.println("About to execute step: " + scenario.getName()); }AfterStepThe @AfterStep hook in Cucumber is designed to run a block of code after every single step of your test scenario. This capability is essential for tasks such as taking screenshots after each step to help with debugging or logging detailed information about the execution of each step. Implementing the @AfterStep hook can significantly enhance the visibility and traceability of your tests, making it easier to identify where an issue occurred if a test fails.@AfterStep Hook@AfterStep public void afterStep(Scenario scenario) { Utils.wait(3); final byte[] screenshot = ((TakesScreenshot) driver).getScreenshotAs(OutputType.BYTES); scenario.attach(screenshot, "image/png", "image"); }Conditional Hooks To further refine and control the execution of hooks, Cucumber provides the feature of conditional hooks with tags. Tags in Cucumber are metadata assigned to scenarios or feature files, and they can be used to conditionally apply hooks. For instance, if you have specific setup or teardown procedures that should only run for certain tests, you can tag those tests accordingly and define hooks that only trigger for those tags.Conditional Tagsimport io.cucumber.java.Before; import io.cucumber.java.After; public class Hooks { @Before("@login") public void beforeLogin() { // Code to run before scenarios tagged with @login } @After("@logout") public void afterLogout() { // Code to run after scenarios tagged with @logout } }ConclusionIncorporating hooks into your Cucumber tests is a powerful way to maintain a stable test environment, enhancing the overall reliability of your test suite. With hooks, you gain precise control over your test execution process, ensuring each scenario begins and ends in a consistent state. This mastery can lead to more trustworthy and efficient testing, ultimately contributing to higher quality software. Now that you are comfortable with tags and hooks, it’s time to start Running Your Cucumber Tests & Generating Reports. Running Cucumber Tests & Generating Reports Setting up Hooks and Tags in Cucumber is just the beginning of efficient test automation. Once your environment is configured, the next step is to explore the various methods available for executing your Cucumber scripts.Each method has its unique advantages and use cases. In this guide, we will delve into three primary ways to run your Cucumber tests: The Feature File - This method is ideal for quickly running specific features during development. JUnit Test - This method is suitable for developers looking to perform rapid testing of their scripts with minimal setup. Maven using Terminal - This method is perfect for integrating into continuous integration/continuous deployment.Running as a Cucumber FeatureThe first method to execute your Cucumber script is directly from the feature file. This method is straightforward and does not consider tags. Running As A Cucumber FeatureHow to Execute: Right-click on the feature file and select Run As > Cucumber Feature.Best Use Case: This method is ideal for quickly running specific features during development, allowing you to verify functionality without the need for additional configurations. Running as a Cucumber FeatureThis method does not allow for the use of tags, which can be limiting if you need to run specific subsets of tests.Running as a JUnit TestThe second method involves running your Cucumber scripts using JUnit, which is great for quick testing. Running As A JUnit TestHow to Execute: Open the Runner File and select Run As > JUnit Test.Best Use Case: This method is suitable for testers looking to perform rapid testing of their scripts with minimal setup. Running as a JUnit TestPrimarily used within a local development setup and may not be suitable for larger, continuous integration environments.Configuring Cucumber OptionsOne of the standout features of Cucumber is its ability to integrate with various plugins, which allows users to generate a variety of reports.Common Plugin Options html: This plugin generates a comprehensive HTML report, providing a clear and visually appealing overview of your test results. json: The JSON plugin creates a structured JSON report, offering detailed insights that can be easily integrated into other tools or systems for further analysis. junit: The JUnit plugin produces a standard JUnit XML report, ensuring compatibility with various testing frameworks and continuous integration tools. extents adapter: This plugin generates a visually stunning HTML report with rich formatting and detailed analytics, making it easy to share and present your test outcomes.CucumberOptions@CucumberOptions( features = "src/test/resources/features", glue = "com.masteringqa.stepdefinitions", tags = "@smoketest", plugin = {}, monochrome = true, )Generating ReportsCucumber can generate various types of reports. The most commonly used are HTML and JSON reports.HTML ReportHTML reports are user-friendly and provide a detailed overview of test scenarios, steps, and their outcomes.HTML Report@CucumberOptions( features = "src/test/resources/features", glue = "com.masteringqa.stepdefinitions", tags = "@smoketest", plugin = {"pretty","html:target/cucumber-reports.html"}, monochrome = true, ) Example: HTML ReportJSON ReportJSON reports are useful for integrating Cucumber test results with other tools, such as CI/CD pipelines or dashboards. These reports provide a structured format that can be easily parsed and processed.JSON Reports@CucumberOptions( features = "src/test/resources/features", glue = "com.masteringqa.stepdefinitions", tags = "@smoketest", plugin = {"pretty","json:target/cucumber-reports.json"} monochrome = true, ) Example: JSON ReportExtent HTML ReportThe ExtentCucumberAdapter plugin is a highly versatile and essential tool for modern test reporting, seamlessly integrating with your testing pipeline to deliver a cutting-edge HTML reporting design. Its interactive, visually appealing format transforms test results into clear and actionable insights, making it indispensable for enhancing the efficiency and transparency of your testing processes.Extent HTML Report@CucumberOptions( features = "src/test/resources/features", glue = "com.masteringqa.stepdefinitions", tags = "@smoketest", plugin = {"com.aventstack.extentreports.cucumber.adapter.ExtentCucumberAdapter:"}, monochrome = true, ) Example: Extent HTML Report Ensure you add the plugin to your runner before proceeding!Once the plugin is added, execute the mvn test command to run your tests. After the tests complete, you can view the detailed report generated by the ExtentsCucumberAdapter. This will also work for Running as a JUnit Test method.Running from Terminal using MavenThe third method is running your scripts from the terminal using the mvn test command with the Surefire plugin, ideal for pipeline integration. In this scenario we’ll use the extents report. Running The Test Using Maven Command in TerminalTerminal: mvn test<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <version>3.0.0-M5</version> <configuration> <includes> <include>**/HomeScreenRunner.java</include> </includes> </configuration> </plugin> How to Execute: Open your terminal and navigate to your project directory. Use the command: mvn test. Best Use Case: This method is perfect for integrating into continuous integration/continuous deployment (CI/CD) pipelines, ensuring that tests are automatically run as part of the build process.

An Introduction to Cypress Cypress is a powerful, next-generation front-end testing tool built for the modern web. It is designed to make testing fast, easy, and reliable for developers and QA engineers. Cypress tests anything that runs in a browser, making it an essential tool for web application testing.What is Cypress?Cypress is an open-source testing framework that allows developers to write end-to-end tests, integration tests, and unit tests. Unlike other testing tools, Cypress is built on a new architecture and runs in the same run-loop as the application. This unique approach provides better, more reliable, and faster tests.Key Features of Cypress Time Travel: Cypress takes snapshots as your tests run. You can hover over each command in the Test Runner to see exactly what happened at each step. Debugging: Cypress provides readable error messages and stack traces. It also has the ability to debug directly from Chrome DevTools. Real-time Reloads: Cypress automatically reloads whenever you make changes to your tests. Automatic Waiting: Cypress waits for commands and assertions before moving on. There is no need to add explicit waits or sleeps. Spies, Stubs, and Clocks: Like any good testing framework, Cypress comes with built-in spies, stubs, and clocks.Time TravelCypress is a powerful tool for end-to-end testing, and one of its standout features is Time Travel. This feature allows testers to visually travel back in time through their tests, inspecting every single step, action, and response. By leveraging Cypress Time Travel, testers can debug applications more effectively, quickly identifying where and why tests fail. Cypress Time Travel From TestThe interactive nature of Time Travel means you can hover over commands in the Command Log and instantly see what happened at each point in time, making debugging a breeze. This visual timeline is invaluable for understanding the exact state of your application at any given moment during the test.Debugging with CypressDebugging in Cypress is straightforward and user-friendly. Unlike traditional testing frameworks, Cypress provides real-time feedback and detailed error messages directly in the browser. This means you don’t have to waste time switching between different tools or digging through complex logs. Cypress Debugging Error MessageWith Cypress, you can debug directly within the browser using powerful developer tools. Moreover, Cypress automatically captures screenshots and videos of failed tests, making it easier than ever to pinpoint issues. By using Cypress’s robust debugging capabilities, you can save time and effort, ensuring your tests are both reliable and maintainable.Real-time ReloadsOne of the most impressive features of Cypress is its real-time reloads. Whenever you make a change to your tests or application code, Cypress automatically reloads and reruns the tests. This continuous feedback loop means you can see the effects of your changes immediately, without the need to manually restart the test runner. Cypress Reload On ChangeReal-time reloads significantly speed up the development process, as they allow for instant validation of code changes. This feature is particularly useful for teams practicing Test-Driven Development (TDD) or Continuous Integration (CI), as it ensures that all code modifications are immediately tested and validated.Automatic WaitingCypress takes the headache out of dealing with timing issues in your tests with its Automatic Waiting feature. Traditional test frameworks often require you to add manual waits or timeouts to ensure elements are ready for interaction. However, Cypress automatically waits for elements to appear, animations to complete, and AJAX requests to finish before moving on to the next command. Cypress Automatic Waiting - Super Fast!This intelligent waiting behavior ensures your tests are more reliable and less flaky. With Cypress Automatic Waiting, you no longer need to worry about intermittent test failures caused by elements not being ready. This feature helps create robust tests that are more reflective of real user interactions.Spies, Stubs, and ClocksCypress provides powerful utilities for spying, stubbing, and controlling time, which are essential for comprehensive testing. With spies, you can monitor function calls and ensure your application behaves as expected. Stubs allow you to replace real functions with mock implementations, making it possible to test your application in isolation.This is particularly useful for simulating different responses and scenarios without relying on a live backend. Additionally, Cypress’s clocks feature lets you control and manipulate the passage of time in your tests, allowing you to test time-dependent code more effectively. These tools give you full control over your test environment, enabling you to simulate complex scenarios and ensure your application is rock-solid under any condition.ConclusionCypress is a game-changer for front-end testing. Its ease of use, powerful features, and reliable testing environment make it an indispensable tool for developers and QA engineers. In the next guide, we will dive into the Installation and Setting Up Cypress , getting you ready to write your first test. Installing and Setting Up Cypress Now that you understand what Cypress is and its key features, it’s time to set up your environment. This guide will walk you through installing Cypress and configuring it for your project.PrerequisitesBefore installing Cypress, ensure you have the following prerequisites: Node.js: Cypress is built on Node.js, so you need to have Node.js installed on your system. You can download it from Node.js official website. Package Manager: You can use either npm (comes with Node.js) or yarn to install Cypress. Text Editor or IDE: Any text editor or IDE will work, but using one with good JavaScript support like Visual Studio Code is recommended. Viewing The Cypress WebsiteInstalling CypressGetting started with Cypress is a breeze, especially when it comes to the installation process.Initialize Your ProjectFirst, if you haven’t already set up a project, you’ll need to initialize one. This begins with creating a new directory that will house your project files. Once your directory is ready, the next step is to initialize a new Node.js project. This can be done effortlessly by navigating to your directory and running the appropriate command to initiate the Node.js setup, see below.Initialize Cypress Projectmkdir my-first-cypress-project cd my-first-cypress-project npm init -y Initializing A New NPM ProjectInstall Cypress via NPMWith your project initialized, the focus shifts to installing Cypress. Cypress can be easily added to your project via NPM, ensuring it’s saved as a development dependency. This is crucial as it helps maintain a clean and organized project environment. To install Cypress, simply run the command that adds it to your project dependencies, and NPM will take care of the rest.NPM: Installing Cypressnpm install cypress --save-dev Installing Cypress via NPMVerify InstallationAfter the installation process is complete, it’s important to verify that Cypress has been installed correctly. This can be done by opening Cypress through a command in your terminal. If everything has been set up properly, Cypress will launch, indicating that your installation was successful.NPM: Open Cypressnpx cypress open Cypress Installed SuccessfullyCypress StructureWhen you first open Cypress, it automatically generates a structured directory designed to streamline your testing workflow. This directory, simply named cypress, is home to several key folders that play a pivotal role in organizing your test suite.Cypress Project Structurecypress/ ├── fixtures/ ├── e2e/ ├── plugins/ └── support/ fixtures: This is where you store any static data that your tests might need. Whether it's sample JSON files or other data formats, this folder is your go-to place for predefined data sets that help simulate various test scenarios. e2e: This is where the actual test scripts reside, ready to be executed. By keeping your test scripts organized in this manner, Cypress ensures that you can easily manage and locate them as your testing suite grows. plugins:Cypress allows you to extend its functionality through various plugins, and this is the folder where those plugins live. By utilizing plugins, you can customize and enhance Cypress to better fit your project's specific needs. support: This folder is where you'll store custom commands and configurations. This is the backbone of your test suite’s functionality, allowing you to define reusable commands and tailor Cypress's behavior to match your testing requirements.Configure CypressCypress is configured using a file named cypress.json. This configuration file is crucial as it allows you to set various options to control Cypress’s behavior. For instance, you can specify the baseUrl for your tests, like so: cypress.json{ "baseUrl": "http://localhost:3000" }ConclusionWith Cypress installed and your directory structure in place, you’re now ready to dive deeper. The next step is Writing Your First Test In Cypress, which we will explore in the following guide. This will provide you with hands-on experience with Cypress, allowing you to harness its powerful features effectively and efficiently. This foundational understanding is crucial for anyone serious about mastering end-to-end testing with Cypress. Writing Your First Test in Cypress With Cypress installed and set up, it’s time to write your first test. This guide will walk you through creating a basic test to validate that Cypress is correctly configured and running. Writing tests in Cypress is intuitive and straightforward. Here’s an example of a basic test:Writing a Cypress TestHere’s an example test that checks if the login page loads correctly when the icon is clicked from the Home screen.Create a New Test FileCreate a new file in the cypress/e2e/home directory. In this example we’re going to create a new test file called home.cy.js. This file is going to house all of our scenarios related the Home page. home.cy.jsdescribe('Home Screen', () => { it('should navigate to the login page when the login icon is clicked', () => { const kicksAppsUrl = 'https://jahmalrichard.github.io/kicks-flutter-web-app/'; cy.viewport(1920, 1080); // Set the viewport to a standard desktop size cy.visit(kicksAppsUrl); // Load the web application cy.get('flt-semantics[aria-label="login-icon"]') .should('be.visible').click(); // Locate and click the login icon cy.get('flt-semantics[aria-label="Sign In"]') .should('exist'); // Verify navigation to the login page }); });In this example, the describe block is used to group tests related to the Home Screen. Inside the it block, we have a single test case that checks whether the application correctly navigates to the login page when the login icon is clicked. Test Setup: The first step in the test is setting up the viewport size to 1920x1080 pixels. This ensures the test runs in a simulated screen size that closely mirrors a typical desktop display. This is optional. Visiting the Application URL: The next step involves visiting the specific URL of the web application. This is done using cy.visit(kicksAppsUrl);, where kicksAppsUrl is a variable holding our application's URL. Interacting the Login Icon: Once the page is loaded, the test uses cy.get to locate the login icon on the page. This element is identified using a semantic label aria-label="login-icon" within the flt-semantics tag. The should('be.visible') command ensures that the icon is visible before attempting to click it. This step is critical as it validates that the icon is correctly displayed on the page before any action is performed. Asserting the URL Path: The test asserts that the URL now contains the /sign-in path using cy.url().should('include', '/sign-in'). This check ensures that the application navigates to the correct page after the icon is clicked. Verifying Navigation to the Login Page: After clicking the login icon, the test checks whether the application has navigated to the login page by looking for an element with the aria-label="Sign In". The should('exist') command is used here to confirm that this element is present in the DOM, which indicates successful navigation. Run Your TestOpen Cypress Test Runner if it’s not already openRun Testnpx cypress open Browsers Available To Run Test OnSelect your test file home.cy.js from the Test Runner to execute it. You should see your test running in the browser, with all assertions passing. Cypress Runner with Home Spec Cypress Run Home Test - PassedConclusionYou’ve written and executed your first Cypress test. This basic test demonstrates how to visit a page, interact with elements, and make assertions. In the next guide, we will delve into Setting Up A Reliable & Scalable Tests to better understand how to organize and manage your test suite effectively. Setting Up a Reliable and Scalable Test Suite In Cypress In this guide I’ll walk you through some essential Cypress features, such as setting the baseUrl, using the beforeEach hook, organizing tests with nested describe blocks, and creating custom commands. Let’s dive in!Using the baseUrl to Store Your Test URLOne of the first steps in setting up a Cypress project is configuring your test environment. Instead of hardcoding URLs throughout your tests, you can streamline your code by using the baseUrl configuration in Cypress. This not only makes your tests more maintainable but also easier to read and manage. Setting the baseUrl: To set up your baseUrl, navigate to your cypress.json file (located in the root of your Cypress project) and add the following configuration:cypress.config.jsconst { defineConfig } = require("cypress"); module.exports = defineConfig({ e2e: { defaultCommandTimeout: 10000, // 10 seconds pageLoadTimeout: 60000, // 60 seconds for page load baseUrl: 'https://jahmalrichard.github.io/kicks-flutter-web-app/', setupNodeEvents(on, config) { }, }, }); With this configuration, you can now visit your URL automatically during test.cy.visitcy.visit('/');Cypress automatically prepends the baseUrl to any relative URL you provide, making your tests more readable and easier to maintain. If you ever change your testing environment (e.g., from localhost to a staging server), you only need to update the baseUrl in one place.Using the beforeEach Hook in CypressThe beforeEach hook is a powerful feature in Cypress that allows you to run a specific piece of code before each test within a describe block. This is particularly useful for setting up a consistent test environment, ensuring that each test starts with the same conditions. Implementing beforeEach: In our sample script, we see the beforeEach hook used to set the viewport size and visit the homepage before each test. cy.viewport(1500, 780): Sets the browser window size to 1500x780 pixels, ensuring consistency across all tests. cy.visit('/'): Navigates to the homepage, using the relative path since baseUrl is set. cy.wait(5000):Pauses the test for 5 seconds to ensure that all elements on the page are loaded and ready for interaction.beforeEachdescribe('Home Screen', () => { beforeEach(() => { // This will run before each test, ensuring the website is always launched with custom viewport cy.viewport(1500, 780); cy.visit('/'); cy.wait(5000); // Ensures the page has fully loaded before running the test }); // Test cases will follow here... });This setup ensures that every test in the Home Screen block starts with the same conditions, leading to more reliable and predictable test outcomes.Using Nested describe BlocksAs your test suite grows, organizing your tests becomes crucial. Cypress allows you to structure your tests using nested describe blocks, which is particularly useful for grouping related tests and making your test suite easier to navigate.Implementing Nested describe Blocks:In the provided script, we see a nested describe structure used to organize tests related to the Home Screen and its Navigation Menu: Outer describe block (Home Screen): Groups all tests related to the home screen of your application. Nested describe block (Navigation Menu): Further organizes tests that specifically deal with the navigation menu.Nested describe()describe('Home Screen', () => { beforeEach(() => { cy.viewport(1500, 780); cy.visit('/'); cy.wait(5000); }); describe('Navigation Menu', () => { it('should navigate to the About Us page when the about link is clicked', () => { cy.get('flt-semantics[aria-label="About us"]') .should('be.visible') .focus() .click({ force: true }); cy.url().should('include', '/about-us'); const aboutUsPageHTitle = createMultilineSelector('About us'); cy.get(aboutUsPageHTitle).should('be.visible'); }); // Additional test cases for other navigation links... }); });This structure not only makes your tests easier to manage but also provides clear reporting when tests are run. You can easily identify which part of your application a failing test belongs to based on the describe block hierarchy.Using Custom Commands in CypressCypress allows you to extend its functionality by creating custom commands, which can simplify repetitive tasks and make your tests more expressive. Custom commands are particularly useful for abstracting complex interactions or frequently used selectors.Creating and Using a Custom Command:In the provided script, the createMultilineSelector command is imported and used to generate a selector for elements with multiline text. createMultilineSelector: This custom command likely returns a selector that matches elements based on their aria-label attribute, specifically targeting multiline text. By using this command, we avoid duplicating complex selectors throughout our tests. Usage in Tests:Instead of writing out the full selector each time, you simply call createMultilineSelector('About us'), making the test more readable and easier to maintain.Using createMultilineSelectorimport { createMultilineSelector } from '../../support/e2e.js'; describe('Home Screen', () => { beforeEach(() => { cy.viewport(1500, 780); cy.visit('/'); cy.wait(5000); }); describe('Navigation Menu', () => { it('should navigate to the About Us page when the about link is clicked', () => { cy.get('flt-semantics[aria-label="About us"]') .should('be.visible') .focus() .click({ force: true }); cy.url().should('include', '/about-us'); const aboutUsPageHTitle = createMultilineSelector('About us'); cy.get(aboutUsPageHTitle).should('be.visible'); }); // Additional test cases... }); });Creating Custom CommandsYou can define custom commands in the cypress/support/e2e.js file. Here’s how you might define the createMultilineSelector command:Custom function – createMultilineSelector()import './commands' export function createMultilineSelector(text) { let selector = 'flt-semantics[aria-label="'; for (let i = 0; i < text.length; i++) { selector += text[i]; if (i < text.length - 1) { selector += '\n'; // Add a newline after each character, except the last one } } selector += '"]'; return selector; }This function dynamically creates a selector that matches any element whose aria-label contains the specified text, making it versatile for various testing scenarios. ConclusionNow that we have our Cypress script set up in a scalable state, we’re ready to take the next step Running Test Scenarios in Cypress to ensure our application behaves as expected across different user interactions. This is where the true power of Cypress shines. By crafting various test scenarios, we can simulate real-world usage patterns, validating that all parts of our web application function correctly under different conditions. Running Test Scenarios in Cypress Before diving into the methods of running tests, let’s first expand our test suite with a few additional scenarios. These new tests will help us better understand the different ways Cypress can be utilized.Enhancing the Home Screen ScenariosIn this guide we’ll be going through the application, checking the links in the header menu like Products, Login, Cart. These are essential user flows, and ensuring they work correctly is vital for a seamless user experience. For instance, when the user clicks on the Products link, the application should navigate to the Products page, where the title Performance Sneakers should be visible. Similarly, clicking the login icon should direct the user to the sign-in page, with the Sign In button present and ready for interaction. The same applies to the Cart icon, leading the user to a Shopping Cart page, confirming the presence of the Shopping Cart title.Below is the enhanced version of the previous home screen test file, which includes test the new use cases mentioned above.Enhanced Home Screen Scenariosit('should navigate to the Products page when the products link is clicked', () => { cy.get('flt-semantics[aria-label="Products"]') .should('be.visible') .focus() .click({ force: true }); cy.url().should('include', '/products'); cy.wait(3000); const productsPageTitle = createMultilineSelector('Performance Sneakers'); cy.get(productsPageTitle).should('be.visible'); }); it('should navigate to the Login page when the login icon is clicked', () => { cy.get('flt-semantics[aria-label="login-icon"]') .should('be.visible') .focus() .click({ force: true }); cy.url().should('include', '/sign-in'); cy.get('flt-semantics[aria-label="Sign In"]').should('exist'); }); it('should navigate to the Cart page when the cart icon is clicked', () => { cy.get('flt-semantics[aria-label="cart-icon"]') .should('be.visible') .focus() .click({ force: true }); cy.url().should('include', '/cart'); const shoppingCartTitle = createMultilineSelector('Shopping Cart'); cy.get(shoppingCartTitle).should('be.visible'); });Running Test Using: Cypress RunNow that we’ve expanded our test suite, we can explore different ways to run these tests in Cypress. One approach is using the Cypress run command. This command allows you to run your tests in headless mode, meaning the tests execute without opening a browser window. This method is particularly useful for integrating tests into CI/CD pipelines where you need the tests to run automatically without manual intervention.cypress runnpx cypress run --spec cypress/e2e/home/home-advance.cy.js Cypress Testing Running In Headless ModeRunning Test Using: Cypress OpenAlternatively, you can use the npx cypress open command. This command opens the Cypress Test Runner in a graphical interface, allowing you to manually select and run tests. It’s an excellent way to visually interact with your tests and see them run in real-time, which can be particularly useful during the development phase when debugging issues.cypress opennpx cypress open Choosing E2E Testing To Start Cypress Test Browsers Available To Run Test On List of Cypress Tests To Choose From Cypress Test Runner With A Passed TestRunning Test Using: package.jsonFor convenience, you might want to add commands directly into your package.json file. This allows you to run specific test scripts or open the Cypress Test Runner with a single command.package.json"scripts": { "test": "echo \"Error: no test specified\" && exit 1", "all-e2e-gui": "npx cypress open --e2e", "home-test-headless": "npx cypress run --spec \"cypress/e2e/home/home-advance.cy.js\"" }, Viewing the package.json file. To view the Run Script | Debug Script options, hover your mouse over the script name and it will display. all-e2e-gui : npx cypress open --e2e - This gives you the ability to launch the Test Runner directly from the terminal. home-test-headless: npx cypress run --spec \"cypress/e2e/home/home-advance.cy.js\ - This is to run your home screen tests in headless mode, ensuring that you can quickly execute these tests without needing to manually input commands each time.ConclusionRunning test scenarios in Cypress is a seamless experience, thanks to its versatility in execution methods. By enhancing your test scenarios and leveraging different ways to execute them, you can ensure that your testing process is both efficient and effective. In the next guide you learn about Connecting Your Cypress Project To Cypress Cloud! Connecting Cypress Project to Cypress Cloud Connecting your Cypress project to Cypress Cloud is an essential step to enhance your testing workflow. Cypress Cloud offers robust features such as test recording, parallelization, and integration with CI/CD pipelines, which can significantly improve the efficiency and visibility of your test results. In this guide, we’ll walk through the steps to set up and connect your Cypress project to Cypress Cloud, ensuring a seamless integration.

This compression level strikes a balance between video quality and storage. screenshotOnRunFailure - This feature automatically captures a screenshot whenever a test fails, providing a visual snapshot of the problem at the exact moment it occurs. screenshotsFolder - By setting the screenshotsFolder to 'cypress/screenshots', you ensure that all screenshots are organized in a dedicated folder within your project.Cypress Passed Test With Video PlayBack Cypress Passed Test With Video PlaybackCypress Failed Test With Screenshot Cypress Failed Test With ScreenshotConclusionNow that your Cypress project is connected to Cypress Cloud, you’ll immediately experience the powerful features Cypress Cloud offers. These features include parallel testing, seamless CI/CD integration, and automatic screenshots and videos.In the upcoming guide, we’ll dive deeper into Using Advance Assertions In Cypress. Using Advanced Cypress Assertions In this advanced assertion guide, we delve into various Cypress commands and their functionalities, focusing on enhancing your testing strategy and ensuring your web application is robust and reliable. These commands, including .next(), .eq(), .include(), .within(), .and(), .then(), and others, provide nuanced control over test scenarios, making them indispensable for comprehensive testing.Understanding Cypress AssertionsThe .next() command in Cypress is used to select the next sibling DOM element within a parent element. This command is particularly useful when you need to perform assertions on elements that are dynamically generated or are sequentially placed in the DOM. For example, if you want to test the navigation menu items in a sequence, you can use .next() to move from one item to the next..next()cy.get('.menu-item') .first() .next() .should('have.text', 'About Us'); This snippet selects the first menu item and asserts that the next sibling has the text About Us, helping ensure the navigation menu is correctly ordered.The .eq() command is another powerful tool in Cypress, used to select an element at a specific index. This is extremely useful for assertions where elements are identical in structure but differ in content or position. For instance, if you’re testing a list of products, you can use .eq() to assert specific properties of each product. .eq()cy.get('.product-item') .eq(2).should('contain', 'Laptop'); In this assertion, Cypress selects the third product item (index:2) and checks if it contains the text Laptop which helps verify the correct rendering of products.The .include() assertion checks if a given string or element contains a specific substring or child element. This is essential for validating partial matches in text or the presence of specific elements within a container. For example, you might want to ensure that a promotional banner includes the keyword Discount. .include()cy.get('.banner') .should('include.text', 'Discount'); This code ensures that the banner element has the word Discount, confirming the presence of expected promotional content.Enhancing Test Coverage with .within() and .and()The .within() command allows you to scope your assertions to a specific portion of the DOM. This is particularly valuable when you have a complex structure with repeated classes or IDs, as it enables precise targeting of elements within a specified container. For example, if you want to validate form fields within a login form, .within() helps isolate the form and perform checks without interference from other elements..within()cy.get('.login-form').within(() => { cy.get('input[name="username"]').type('testuser'); cy.get('input[name="password"]').type('password123'); });In this example, Cypress limits the scope to the .login-form container, ensuring that only the form fields inside it are interacted with, enhancing test reliability.The .and() command chains multiple assertions together, allowing for concise and readable test scripts. When you want to verify multiple properties of an element, .and() provides a clean way to do so in a single command..and()cy.get('.notification') .should('be.visible') .and('contain', 'Success'); This snippet checks that a notification is visible and contains the word Success effectively combining two assertions in a streamlined manner.Leveraging .then() for Synchronous TestingCypress’s .then() command is crucial for handling asynchronous operations and chaining commands in a synchronous manner. This is especially useful when you need to perform complex operations that depend on the results of previous commands. For instance, if you want to fetch data from an API and then validate the response within the test, .then() allows you to manage this flow seamlessly..then()cy.request('GET', '/api/products').then((response) => { expect(response.status).to.eq(200); expect(response.body).to.have.length.greaterThan(0); }); In this example, Cypress sends a GET request to the /api/products endpoint and then uses .then() to assert that the response status is 200 and that the response body contains more than zero products, ensuring the API’s correctness.Building Reliable Tests with CypressCombining these advanced Cypress commands allows developers to create robust and reliable tests that cover a wide range of scenarios, from simple UI checks to complex user flows. Utilizing .next(), .eq(), .include(), .within(), .and(), and .then() helps ensure your application behaves as expected under various conditions, enhancing test coverage and confidence in the application’s stability.ConclusionMastering these commands enables testers to write thorough, maintainable, and efficient Cypress tests for various applications, from single-page to e-commerce platforms. These assertions offer the flexibility to simulate real-world user interactions, ensuring higher-quality web applications and an improved user experience. In the next guide, we will explore Writing API Tests in Cypress. Writing API Tests in Cypress API testing is a critical component of modern software development, ensuring that your application’s back-end services are robust, reliable, and performant. Cypress, a popular end-to-end testing framework, is not only capable of testing the UI but also excels at API testing. In this guide, we’ll explore how to write API tests in Cypress, dive into some practical examples, and discuss the differences between cy.request and cy.api, two powerful commands for API testing in Cypress.cy.requestCypress provides a seamless way to perform API testing by leveraging its cy.request command. This command is ideal for making HTTP requests to your application’s backend or any third-party services it interacts with. Using cy.request, you can validate the response status, headers, body, and even the timing of API calls, making it an essential tool for API testing in Cypress. For instance, if you’re testing a REST API, you can easily send GET, POST, PUT, or DELETE requests and assert that the server’s responses are as expected.Let’s consider an example where we want to test a simple GET request to retrieve a list of users from an API endpoint. Using cy.request, the test might look something like this:cy.request()describe('API Testing with Cypress', () => { it('should fetch a list of users', () => { cy.request('GET', 'https://jsonplaceholder.typicode.com/users').then((response) => { expect(response.status).to.eq(200); expect(response.body).to.have.length(10); expect(response.body[0]).to.have.property('name'); }); }); });In this example, cy.request sends a GET request to the specified URL. The .then() method is used to handle the response, allowing us to assert that the status code is 200 and that the response body contains an array of users with the expected length and structure. This simple yet powerful approach highlights how Cypress makes API testing straightforward and accessible.cy.apiWhile cy.request is a fantastic tool for making HTTP requests, Cypress also offers the cy.api command through its official plugin, @cypress/plugin-api. This plugin provides a more feature-rich alternative to cy.request and is particularly useful for more complex API testing scenarios. One of the key differences between cy.request and cy.api is that cy.api automatically records requests and responses in the Cypress command log, making debugging and test reviews more intuitive.Consider a scenario where you need to perform a POST request to create a new user and validate the response. Using cy.api, you can write the following test:cy.api()describe('Advanced API Testing with Cypress', () => { it('should create a new user', () => { cy.api({ method: 'POST', url: 'https://jsonplaceholder.typicode.com/users', body: { name: 'John Doe', email: 'john.doe@example.com', phone: '1-770-736-8031 x56442', }, }).then((response) => { expect(response.status).to.eq(201); expect(response.body).to.have.property('name', 'John Doe'); }); }); });In this example, cy.api is used to send a POST request with a JSON payload to create a new user. The test then checks that the server returns a status code of 201 (indicating successful creation) and that the response body contains the correct data. The enhanced logging capabilities of cy.api provide valuable insights into the request and response, making it easier to diagnose any issues that arise during testing.ConclusionCypress is a versatile framework that not only excels at end-to-end testing but also provides robust tools for API testing. Whether you choose to use cy.request for its simplicity and flexibility or cy.api for its enhanced logging and feature set, Cypress makes it easy to implement and maintain high-quality API tests. By incorporating API testing into your Cypress test suite, you can ensure that both your front-end and back-end components work harmoniously together, leading to a more reliable and resilient application.

By using Eclipse IDE, a comprehensive platform for Java development, you can leverage tools and shortcuts to enhance the refactoring process. Eclipse’s built-in support for automated refactoring, code organization, and error-checking makes it an excellent choice for handling large test suites. Proper refactoring ensures tests are reliable, efficient, and sustainable as your project scales.Identify Problematic Test CodeStart by reviewing your test code for issues that may hinder maintainability or clarity. Tests that are difficult to understand, redundant, or prone to failure often signal the need for refactoring. Use Eclipse’s Code Smells feature to identify areas for improvement, such as duplicated code, overly complex methods, or excessive dependencies. Prioritizing areas that impact test readability or lead to frequent failures will yield the most benefit from refactoring.Keep Tests Small and FocusedOne of the primary goals in refactoring is to ensure each test has a single responsibility. Tests that cover multiple scenarios or actions are not only harder to debug but can also mask issues that may only occur in specific conditions. Refactoring large tests into smaller, focused tests improves readability and maintainability. In Eclipse, you can easily extract methods or classes, allowing for the separation of test responsibilities and making each test easier to manage.Use Descriptive Naming ConventionsDescriptive and consistent naming conventions make your test code self-explanatory, reducing the need for excessive comments or documentation. Rename variables, methods, and classes to reflect their purpose accurately, ensuring that anyone reading the test code understands its functionality without additional context. In Eclipse, the Rename (Shift+Alt+R) refactoring tool allows you to rename elements safely across your codebase, updating references automatically.Best Practices for Refactoring Test Code in EclipseUtilize Parameterized TestsRepeating the same logic across multiple tests with slight variations can lead to redundant code and maintenance issues. Parameterized tests allow you to pass different sets of data to a single test method, reducing code duplication. This approach is particularly effective in unit testing frameworks like JUnit, integrated into Eclipse. Use the JUnit Parameterized class or JUnit 5’s @ParameterizedTest to refactor repetitive tests, creating a cleaner and more maintainable suite.Organize Tests by FunctionalityOrganizing your test cases by functionality, such as creating folders or packages for specific modules, components, or screens, provides a clear structure to your tests. This structure enhances readability and makes it easier to locate specific tests. In Eclipse, you can create custom packages and use annotations to categorize tests, making it easier to navigate large test suites.Refactor Assertions for ClarityAssertions are critical in determining if tests pass or fail, so it’s essential to keep them simple and descriptive. Avoid complex assertion logic that can obscure the intent of the test. Using custom assertion methods can add clarity, especially in complex test scenarios. Eclipse supports a range of assertion libraries, such as AssertJ and Hamcrest, which provide fluent assertion syntax and enhance readability.Leverage Code Coverage ToolsCode coverage tools, like EclEmma for Eclipse, help you identify untested code sections, offering insights into areas that may require additional tests. High coverage does not guarantee perfect tests but helps ensure that your code is well-tested and reliable. Use coverage reports to guide your refactoring efforts and ensure critical paths are tested comprehensively.ConclusionRefactoring test code is a vital practice for maintaining high-quality, reliable test suites. By following these best practices in Eclipse, quality testers can improve code readability, reduce redundancy, and enhance test efficiency. From using parameterized tests and helper methods to adopting mocking and organizing tests by functionality, Eclipse offers numerous tools to simplify and streamline the refactoring process. Embrace these strategies to keep your test code clean, maintainable, and adaptable to future project requirements. Remember, consistent refactoring is the key to sustainable test automation that scales effectively with your application.

Flutter’s hot reload, powerful widgets, and single codebase allow developers and testers to work together more efficiently, ensuring faster releases and higher-quality products. To take your Flutter expertise to the next level, explore our guide on Setting Up a Testing Environment in Flutter and learn how to create a solid foundation for your testing workflows. Setting Up a Testing Environment in Flutter Setting up a testing environment in Flutter is a critical step for ensuring that your applications are bug-free, maintainable, and efficient. Flutter, with its growing popularity as a framework for cross-platform mobile development, makes testing relatively straightforward but requires a well-configured environment for comprehensive testing. This guide will walk you through the process of setting up a testing environment in Flutter, catering specifically to the needs of QA testers and developers. Setting Up FlutterSetting Up Your Flutter Development EnvironmentBefore diving into testing, ensure that your Flutter development environment is correctly configured. Install Flutter SDK by following the instructions on the official Flutter website. This installation will include essential tools such as flutter doctor, which helps diagnose configuration issues. Install Dependencies Run Flutter Doctor Install Dependencies: Make sure you have Dart SDK, an integrated development environment like VS Code and mobile simulators/emulators set up for testing on different devices.Run flutter doctor: Execute flutter doctor in your terminal to verify that your setup is complete, and to ensure you have all the required dependencies installed.Understanding Different Types of Flutter TestsTo effectively set up a testing environment in Flutter, you need to understand the three types of testing in Flutter: Unit Tests: Unit tests verify individual units of code, like functions or methods. They are useful for testing business logic in isolation. Widget Tests: Widget tests validate the behavior of a single widget. They run faster than integration tests and help in ensuring that individual parts of the UI work as expected. Integration Tests: Integration tests evaluate how different widgets work together in an application. These tests help simulate real user interactions to identify any issues.Flutter provides built-in testing libraries such as flutter_test, which offers tools for all three types of tests.Configuring the Testing Environment in FlutterAdding Testing DependenciesThe first step in configuring the testing environment in Flutter is to add the necessary dependencies to your project. Open the pubspec.yaml file and add the following dependencies:pubsepec.yml dev_dependencies: flutter_test: sdk: flutter mockito: ^5.0.0 integration_test: sdk: flutter Flutter Pubspec Setup flutter_test: This is the primary library for unit and widget testing in Flutter. integration_test: This package facilitates integration testing by allowing you to automate user flows.Setting Up Test Files In your project structure, create a folder named test/ to store your test files. Keep your test files organized based on the features or functionalities being tested. For instance: test/unit/ for unit tests. test/widget/ for widget tests. integration_test/ for integration tests.This folder structure will make it easier to maintain and navigate your tests as the application scales.Writing a Simple Unit TestUnit testing in Flutter starts by creating a new .dart file under test/unit/. Here is an example of a simple unit test:Sample Unit Testimport 'package:flutter_test/flutter_test.dart'; import 'package:your_app/math_utils.dart'; void main() { test('Adding two numbers should return correct sum', () { final result = addNumbers(2, 3); expect(result, 5); }); }In this example, addNumbers() is a method from math_utils.dart that you want to test. The test() function helps define the test scenario, and the expect() function is used to validate the result.Running TestsTo run your tests, use the following command in the terminal:bashflutter testThis command will run all the unit and widget tests in your test/ directory.ConclusionSetting up a testing environment in Flutter is an essential task for both QA testers and developers aiming for high-quality, reliable applications. A well-configured environment includes proper setup of the Flutter SDK, addition of essential testing dependencies, organized test files, and the ability to run unit, widget, and integration tests.To dive deeper into Flutter testing, explore the next guide, Writing and Running Unit Tests in Flutter, where you’ll learn how to write effective unit tests and execute them seamlessly. Writing and Running Unit Tests in Flutter Writing and running unit tests in Flutter is a crucial part of the development process that ensures the stability and reliability of your codebase. In this guide, we’ll cover the essentials of writing and running unit tests in Flutter, enabling you to improve code coverage and boost application stability.Introduction to Unit Testing in FlutterUnit testing is a software testing technique where individual units or components of an application are tested in isolation. In Flutter, a unit test validates a specific part of your logic, typically a function, method, or class, to ensure that it performs as expected. By writing and running unit tests in Flutter, you can catch bugs early, improve the overall reliability of your app, and ensure that each unit behaves predictably even as the code evolves. Flutter provides a simple yet powerful testing environment that includes tools like flutter_test and integration with popular third-party packages. Before diving into writing and running unit tests in Flutter, it’s important to understand the fundamental principles and tools used to create effective unit tests.Setting Up Unit Tests in FlutterTo get started with unit testing in Flutter, you need to set up the appropriate dependencies in your project. Flutter includes a package called flutter_test by default, which provides various functions and utilities that make writing tests easier. You can find it in your pubspec.yaml file:pubspec.yaml dev_dependencies: flutter_test: sdk: flutterWriting Unit Tests in FlutterWhen writing unit tests in Flutter, it is essential to focus on testing individual units of logic in isolation. Unit tests should be short, simple, and easy to maintain. Follow these steps to write a unit test in Flutter:Create a Test FileTest files should be placed in the test/ directory, which Flutter automatically generates when you create a new project. To create a test file, add a new .dart file under the test/unit directory. In this example we will call the file sign_in_screen_unit_test.dart. Flutter Unit TestInspect the Sign Up Screen ControllersWe will focus on examining the functionality of the sign-in screen in our project by exploring the sign_in_screen controller. This controller plays a pivotal role in handling user interactions with the sign-in screen. Specifically, it is responsible for capturing and processing the input data entered in the username and password fields. SigninScreen ControllerThe SignInController controller serves as the bridge between the UI and the business logic, ensuring that the text entered by the user is properly validated and prepared for authentication.Write Your Test CasesWhen writing test cases for the sign-in screen controller, focus on covering all key functionalities and edge cases. Test for valid and invalid inputs, such as correct and incorrect username-password combinations, empty fields, and valid formats.Here’s the code for the SignInController tests:Unit Test Exampleimport 'package:flutter_test/flutter_test.dart'; import 'package:get/get.dart'; import 'package:richapp/controller/sign_in_controller.dart'; void main() { group('SignInController Tests', () { late SignInController controller; setUp(() { controller = Get.put(SignInController()); }); tearDown(() { Get.delete<SignInController>(); }); test('should initialize with empty text controllers', () { expect(controller.emailOrUserNameController.text, isEmpty); expect(controller.passwordController.text, isEmpty); expect(controller.emailController.text, isEmpty); }); test('should update emailOrUserNameController text correctly', () { controller.emailOrUserNameController.text = 'testuser'; expect(controller.emailOrUserNameController.text, 'testuser'); }); }); } Understanding the Tests Test Initialization (setUp and tearDown) Each test is set up with a fresh instance of SignInController using Get.put, ensuring no shared state between tests. After each test, tearDown ensures the controller is removed using Get.delete. Testing Default Values The first test checks whether the emailOrUserNameController, passwordController, and emailController are initialized with empty text. This ensures the controller starts in a clean state. Testing Text Update The second test verifies that the text in emailOrUserNameController updates as expected when modified. This is a simple check for setter functionality.Running Unit Tests in FlutterOnce you have written your unit tests, it’s time to run them to ensure your code works as expected. You can run unit tests in Flutter using the following command:Run Flutter Unit Test# Runs all the tests flutter test # Run tests on in the unit directory flutter test/unit/ This command runs all the test files located in the test/ directory, including any subdirectories such as test/unit/, and displays the results in the terminal. If you wish to target a specific directory or test file, you can do so by providing the relative file path as an argument: Run Flutter Test vis Pathflutter test test/unit/sign_in_screen_widget_test.dartFlutter will execute the test cases and report the results, including any errors or failed tests. It is good practice to frequently run tests during development to catch issues early. Flutter Unit Test ResultsBest Practices for Writing and Running Unit Tests in FlutterTo ensure that your unit tests are effective and easy to maintain, consider the following best practices: Keep Tests Simple and Focused: Each test should focus on one specific behavior. This makes it easier to identify the root cause of any failure. Use Meaningful Test Names: Clearly describe what the test is validating so that anyone reading the test results understands the purpose of the test. Run Tests Frequently: The sooner you catch a bug, the easier it is to fix. Run tests frequently to catch issues as soon as possible. Ensure Code Coverage: Aim for high test coverage, but remember that quality is more important than quantity. Cover critical logic and edge cases, but avoid writing redundant tests.ConclusionWriting and running unit tests in Flutter is a fundamental practice for ensuring the reliability and stability of your application. This unit test demonstrates how to ensure your SignInController behaves as expected in terms of initialization, state updates, and resource management. Writing clear, focused tests like these can help catch bugs early and maintain a robust codebase.To explore the next step in Flutter testing, check out our guide on Widget Testing in Flutter, where you’ll learn how to test individual widgets effectively to enhance your application’s quality. Widget Testing in Flutter Widget Testing in Flutter is an essential part of the development and QA process, ensuring that individual components of a Flutter app function as expected. Unlike unit tests that focus on the smallest pieces of logic or integration tests that test larger portions of the app, widget testing focuses specifically on validating the behavior of UI components. By effectively employing widget tests, you can validate that widgets render correctly, handle user interactions as expected, and ensure UI changes propagate correctly. This guide aims to provide QA testers and developers with a clear understanding of widget testing in Flutter and practical steps to implement it effectively.What Is Flutter Widget Testing?Widget testing is all about ensuring that individual widgets in your Flutter application behave as expected. Unlike unit tests that focus on logic and computations, widget tests verify the UI and its interactions. For our Sign-In screen, we’ll simulate user actions and validate the UI’s response to these interactions. Running All Widget Tests in VSCodeSetting Up the Test EnvironmentBefore writing widget tests, you need to set up a robust test environment. In this project, I’ve used flutter_test for writing tests, along with ScreenUtil for responsive layouts and GetX for state management and navigation. Here’s how we prepare the environment to ensure smooth testing workflows.To get started with widget testing, follow these steps: Creating Widget Test File Create a New Test File: Navigate to the test/unit directory in your Flutter project and create a new Dart file. Since we're testing the sign in screen, let's name itsign_in_widget_test.dart. Add a Main Function: Inside the newly created file, add the main function to act as the entry point for your test. It should look like this: void main {}. Set Up the Test Environment: Add any dependencies or utilities you need for testing within the main function. For example, if you are testing a widget with routes or dependencies, ensure those are set up properly. Add a Teardown Function: After each test, it’s essential to reset the state to avoid conflicts between tests. Use the tearDown function for this purpose tearDown(() { Get.reset(); }); Below is a snippet I used to handle building the widget page and managing routes using GetX.Function: buildTestWidgetWidget buildTestWidget(Widget widget) { return ScreenUtilInit( designSize: const Size(430, 932), builder: (_, __) => GetMaterialApp( home: widget, initialRoute: '/', getPages: [ GetPage(name: '/', page: () => SignInScreen()), GetPage(name: '/signUpScreen', page: () => SignUpScreen()), GetPage(name: '/bottomNavigationScreen', page: () => HomeScreen()), ], ), ); }Writing Tests for the Sign-In ScreenVerifying Text Fields and ButtonsThe first step is to ensure that all key widgets are present on the screen. These include the email and password fields, as well as the Sign-In button. Verify email, password, and sign-in button keysWidget Test: Verify email, password, and sign-in button keystestWidgets('Verify email, password, and sign-in button keys', (WidgetTester tester) async { await tester.pumpWidget(createTestScreenWidget(SignInScreen())); await tester.pumpAndSettle(); // Verify widgets by key expect(find.byKey(Key('email_username')), findsOneWidget); expect(find.byKey(Key('password')), findsOneWidget); expect(find.byKey(Key('sign_in_btn')), findsOneWidget); });This test validates that the text fields and button are part of the widget tree, using their unique keys for identification.Testing Button Clicks and NavigationButtons are the core of user interactions. Let’s ensure the Sign-In button is clickable and navigates to the correct screen. Tapping Sign In Button Sign In Button Routing On the Home ScreenWidget Test: Sign In button is clickabletestWidgets('Sign In button is clickable', (WidgetTester tester) async { await tester.pumpWidget(createTestScreenWidget(SignInScreen())); await tester.pumpAndSettle(); // Find the button and tap it final primaryButtonFinder = find.byKey(Key('sign_in_btn')); await tester.tap(primaryButtonFinder); await tester.pumpAndSettle(); // Verify navigation expect(find.byType(HomeScreen), findsOneWidget); });This test not only verifies the button’s presence but also confirms successful navigation to the Home screen.Testing LinksLinks like Forgot Password or Sign Up are equally important. Here’s how to test that the Forgot Password link opens the appropriate modal: Widget Testing LinksWidget Test: Forgot Password link is clickabletestWidgets('Forgot Password link is clickable', (WidgetTester tester) async { await tester.pumpWidget(createTestScreenWidget(SignInScreen())); await tester.pumpAndSettle(); final forgotPasswordFinder = find.byKey(Key('forgot_password_link')); await tester.tap(forgotPasswordFinder); await tester.pumpAndSettle(); // Verify modal content expect(find.text('Forgot Password'), findsOneWidget); }); Similarly, you can test the navigation triggered by the Sign Up link:Widget Test: Tap on Sign Up and navigates to the Sign Up screentestWidgets('Tap on Sign Up and navigates to the Sign Up screen', (WidgetTester tester) async { await tester.pumpWidget(createTestScreenWidget(SignInScreen())); final signUpTextFinder = find.text(Strings.signUp); await tester.tap(signUpTextFinder); await tester.pumpAndSettle(); // Verify navigation expect(find.byType(SignUpScreen), findsOneWidget); });These tests ensure your app’s routes are functioning correctly.Debugging Common IssuesDuring widget testing, you might encounter common errors like RenderFlex overflow or issues with animations. Suppressing these in tests, as shown below, can help: Flutter Error HandlingFlutter Error HandlingFlutterError.onError = (FlutterErrorDetails details) { if (details.exceptionAsString().contains('A RenderFlex overflowed')) { return; // Suppress the error } FlutterError.presentError(details); }; Best Practices for Widget Testing in Flutter Test Small Units: Widget tests should be granular, focusing on small components. This ensures that errors can be easily traced to individual widgets. Mock External Dependencies: When widget testing in Flutter, try to isolate the widget from any external dependencies such as APIs or services. This is achieved using mock data or mock functions. Use Golden Tests: Golden tests can be helpful to ensure your widget matches an expected visual appearance. Golden testing captures the rendered widget as an image and compares it to a reference image to catch unintended UI changes. Run Tests Regularly: Widget tests should be run frequently as part of your CI/CD pipeline to catch bugs early and maintain UI stability.Advantages of Widget Testing in Flutter Faster Execution Reliable Feedback Cost-Efficient Debugging Widget tests run much faster compared to integration tests, as they do not require the full app context to be loaded.Since widget tests run in isolation, they provide highly reliable feedback on individual component behavior without interference from other parts of the application.Early detection of UI bugs prevents costly reworks down the line, especially as your Flutter application scales in complexity.ConclusionWidget testing in Flutter is an indispensable tool for ensuring the reliability and correctness of user interface components. By incorporating widget testing into your development and quality assurance workflows, you can confidently validate the behavior of your app’s building blocks, ultimately delivering a better experience to your users. From understanding the basics to writing comprehensive tests and following best practices, this guide serves as a roadmap for mastering widget testing in Flutter.To take your testing knowledge further, explore our next guide on Integration Testing in Flutter, where we dive deeper into testing complete workflows and interactions within your app. Integration Testing in Flutter Flutter integration testing is a crucial step in ensuring that your app works seamlessly as a whole. It allows us to verify user flows, interactions between widgets, and the final output as seen by the user. In this guide, I’ll walk you through the process of creating an integration test for a Flutter app using a complete flow from a WelcomeScreen to a HomeScreen. By focusing on the text fields, buttons, and navigation routes, we’ll simulate real-world user interactions. If you’re looking to strengthen your Flutter testing toolkit, this is a great place to start.What is Integration Testing in Flutter?Integration testing in Flutter bridges the gap between unit tests and end-to-end tests. While unit tests validate individual methods or widgets, integration tests validate entire user flows across screens. This ensures the components work together harmoniously.Let’s take a practical example: a Sign In flow. We’ll verify that all interactive elements, such as text fields and buttons, function correctly. Additionally, we’ll ensure the navigation routes transition the user seamlessly between screens. Our integration test will involve three screens: WelcomeScreen , SignInScreen , and HomeScreen . Flutter Integration Test Running On iPhoneSetting Up Flutter Integration TestingWe begin with the following Flutter widget code. It sets up three key screens: WelcomeScreen: The starting screen offering options to [direction]Sign In[/direction] or [direction]Sign Up[/direction]. SignInScreen: The screen where users input their credentials. HomeScreen: The destination screen once a user signs in successfully.Writing Your First Integration TestTo start, create a new file in the integration_test directory, such as sign_in_screen_e2e_test.dart. This file will define tests to interact with the sign screen, simulating user flows like signing in. Flutter Integration Test File NameBegin by importing the necessary packages, including flutter_test for testing, integration_test for simulating interactions, and main.dart from your app. Use an alias like app for main.dart to avoid naming conflicts and make it clear you’re referencing your app’s entry point.Initialize the integration test environment by calling IntegrationTestWidgetsFlutterBinding.ensureInitialized(). This setup allows you to simulate real-world app usage.Integration Test – main.dart as appimport 'package:flutter/material.dart'; import 'package:flutter_test/flutter_test.dart'; import 'package:integration_test/integration_test.dart'; import 'package:get/get.dart'; import 'package:richapp/routes/routes.dart'; import 'package:richapp/main.dart' as app; void main() { IntegrationTestWidgetsFlutterBinding.ensureInitialized(); //...Testing the WelcomeScreenThe first step in our test is verifying the WelcomeScreen UI elements and functionality. The test checks if SIGN IN and SIGN UP buttons are displayed and functional. Inside the testWidgets function, call app.main() to launch your app. Flutter App Welcome ScreenWelcome Screen ElementstestWidgets('Complete flow from WelcomeScreen to HomeScreen', (WidgetTester tester) async { // Builds and loads the test app app.main(); // Wait for the WelcomeScreen to load await tester.pumpAndSettle(); // Verify WelcomeScreen is displayed expect(find.text('SIGN IN'), findsOneWidget); expect(find.text('SIGN UP'), findsOneWidget); // Tap the Sign In button on the WelcomeScreen await tester.tap(find.text('SIGN IN')); //await tester.pumpAndSettle(); await tester.pump(Duration(milliseconds: 1000)); //... The expect assertions confirm the presence of buttons, and tap simulates the user’s action of tapping SIGN IN .Testing the Sign In ScreenAfter navigating to the SignInScreen, the test verifies the presence of input fields for email and password, as well as the SIGN IN button. iPhone: Sign In ScreenSignIn Screen Elements// Verify SignInScreen is displayed expect(find.byKey(Key('email_username')), findsOneWidget); expect(find.byKey(Key('password')), findsOneWidget); expect(find.byKey(Key('sign_in_btn')), findsOneWidget); // Enter email and password await tester.enterText(find.byKey(Key('email_username')), 'test@example.com'); await tester.enterText(find.byKey(Key('password')), 'password123'); await tester.pump(Duration(milliseconds: 1000)); // Tap the Sign In button await tester.tap(find.byKey(Key('sign_in_btn'))); await tester.pump(Duration(milliseconds: 1000)); //...The enterText method mimics typing credentials into the fields.Testing the HomeScreen Finally, the test validates navigation to the HomeScreen and confirms key UI elements like the AppBar, Dashboard text, and menu icon are present. iPhone: Home ScreenHome Screen Elements// Simulate navigation to HomeScreen Get.toNamed(Routes.bottomNavigationScreen); await tester.pump(Duration(milliseconds: 1000)); // Verify HomeScreen is displayed expect(find.byType(AppBar), findsOneWidget); expect(find.text('Dashboard'), findsOneWidget); expect(find.byKey(Key('menu-icon')), findsOneWidget); //...By checking for these elements, we confirm that the user has successfully reached the HomeScreen.Run Testflutter test integration_test/app_test.dartBest Practices for Integration Testing in Flutter Use Realistic Data When performing integration testing in Flutter, it is best to use realistic test data that mimics real-world scenarios. This helps in identifying issues that could occur in actual usage, such as invalid user input or poor network conditions. Test Complete User Journeys Integration tests should cover complete user journeys rather than isolated actions. For instance, testing a purchase flow should cover product selection, adding to the cart, and completing the checkout. This ensures that all interactions and dependencies between components are working correctly. Optimize Test Execution Time Integration tests can take longer to run compared to unit tests. Make sure to optimize your tests by avoiding unnecessary waits and focusing on critical user flows. This reduces the time required for continuous integration and helps maintain productivity. Device Compatibility Flutter integration tests should be run on both Android and iOS to ensure compatibility across platforms. Consider using cloud-based testing services, such as Firebase Test Lab, to automate the execution of integration tests on a variety of devices.Common Challenges in Integration TestingWhile integration testing in Flutter is immensely valuable, it comes with its challenges. Managing Dependencies Maintenance Managing dependencies such as network responses can be cumbersome. To solve this, consider mocking or stubbing API calls to ensure tests are deterministic and can run without external dependencies. As the Flutter app undergoes changes, your integration tests may need frequent updates to align with new layouts or interactions. To mitigate this, ensure your tests are modular and maintainable.ConclusionIntegration testing in Flutter is a key component of building robust, high-quality mobile applications. By ensuring that all parts of the app work seamlessly together, you reduce the risk of unexpected issues arising in production. Setting up integration tests using the integration_test package allows QA testers and developers to verify entire user flows, enhancing app stability and improving user experience.Keep exploring and integrating Flutter integration testing into your development process.

Writing Your First Patrol Test Case Patrol is an excellent tool for automating Flutter app tests, ensuring that essential app functionalities work as expected across various devices. In this guide, we will walk through writing your first Patrol test, specifically focusing on a common user journey: signing into an app.Setting Up Your Patrol TestBefore diving into the test, ensure that you have Patrol properly installed in your project. With everything in place, let’s begin by writing a test that checks the functionality of a basic sign-in screen. Welcome Screen Sign In ScreenThe sign-in screen typically includes email and password input fields, followed by a sign-in button. Our goal in this Patrol test is to automate the process of entering the email and password, tapping the sign-in button, and verifying the navigation to the dashboard screen.The test begins with a basic import of necessary packages, such as flutter_test for testing utilities and patrol for test automation:Dartimport 'package:flutter/material.dart'; import 'package:flutter_test/flutter_test.dart'; import 'package:patrol/patrol.dart'; import 'package:richpay_app/main.dart' as app;By importing these packages, you set up a testing environment that allows you to interact with the app’s widgets during test execution.Structuring the Patrol TestNext, we define our Patrol test. In this example, we are testing the sign-in process by creating a test that verifies the email input, password input, and sign-in button functionality:Dartvoid main() { patrolTest( 'Sign In Screen - Verifies email input, password input, and sign-in button', ($) async { // Start the app app.main(); await $.pumpAndTrySettle();The patrolTest function defines a specific test case, and inside the function, we start the app using app.main(). This ensures that your app runs in the testing environment, ready to simulate user interactions.Interacting with WidgetsAfter starting the app, we simulate a tap on the sign-in button that appears on the welcome screen. We use the find.byKey method to locate the button using its unique Key:Dartfinal welcomeSignInButton = $(find.byKey(const Key('sign_in_btn'))); await $(welcomeSignInButton).tap(); await $.pumpAndSettle();The $(find.byKey()) function finds the button, and tap() simulates the user pressing it. The pumpAndSettle() method ensures that the app has finished rendering and settles before the next step. Widget Inspector Sign In ButtonEntering Text into Input FieldsNow, let’s verify and interact with the email and password input fields. We first locate the input fields using their respective keys and then simulate entering text:Dartfinal emailTextBox = $(find.byKey(const Key('email_username'))); await $(emailTextBox).enterText('test@gmail.com'); final passwordTextBox = $(find.byKey(const Key('password'))); await $(passwordTextBox).enterText('test123');The enterText() function is essential in automating user input for testing login forms, ensuring that valid text is entered into the relevant fields during the test. Widget Inspector Email & PasswordFinalizing the Test by Tapping the Sign-In ButtonAfter entering the login credentials, we locate and tap the sign-in button to submit the form:Dartfinal signInSignInButton = $(find.byKey(const Key('sign_in_btn'))); await $(signInSignInButton).tap(); // Wait for the navigation to complete after sign-in await $.pumpAndSettle(); Just like before, we use find.byKey to locate the sign-in button and simulate the tap. The app is given time to navigate by calling pumpAndSettle() to ensure all animations and transitions are complete before continuing. Widget Inspector Sign In ButtonVerifying the DashboardFinally, after the sign-in process completes, we want to verify that the user has successfully navigated to the dashboard. We can do this by checking if a specific widget or text related to the dashboard is visible: Widget Inspector Verify Dashboard TextDartexpect(find.text('Dashboard'),findsOneWidget); In this case, we check if the text Dashboard is displayed, confirming that the sign-in was successful and the user has reached the dashboard screen.ConclusionIn the next guide, we’ll dive deeper into Organizing Test Suites in Patrol, helping you structure your tests efficiently for larger applications. Stay tuned for more best practices and techniques to optimize your mobile testing process with Patrol! Organizing Test Suites in Patrol Organizing your test suites efficiently is crucial for maintaining a clean, scalable, and maintainable test architecture, especially when using Patrol, a robust mobile testing framework. One effective strategy is to group tests by screen name, allowing you to organize tests into directories that correspond to the screens in your app. This practice not only improves clarity but also makes it easier for your QA team to locate and maintain specific test cases as your project evolves. Get Access to the Test App & FrameworkPro Members unlock hands-on access to our expertly crafted frameworks. PRO MEMBER Organizing Tests by Screen NameWhen testing a mobile application, screens often represent a core aspect of the user flow. Each screen might have different behaviors, elements, and functionalities that require unique test cases. By organizing tests by screen name, you ensure that: Tests are easily navigable: Team members can quickly find tests related to specific app screens. Reusability and maintenance are enhanced: Updates to screens or features can be isolated to relevant directories without impacting the entire test suite. Collaboration is smoother: Teams can focus on specific screens without having to comb through large, unrelated test files.Create Screen-Specific DirectoriesIn Patrol, you can organize your tests into directories that correspond to specific screens in your app. The following structure is an example:screen directoriesintegration_test/ └── e2e/ ├── dashboard/ │ └── dashboard_test.dart ├── menu/ │ └── menu_test.dart ├── notifications/ │ └── notifications_test.dart ├── profile/ │ └── profile_test.dart ├── sign_in/ │ └── sign_in_test.dart └── sign_up/ └── sign_up_test.dart Organizing Tests by Screen NameEach directory contains the relevant test files for that particular screen. This keeps the tests clean and organized. Here’s how each folder corresponds to the app: dashboard/: Tests focused on ensuring the functionality of the user dashboard. menu/: Tests for menu navigation, clicking and validating the menu items. notifications/: Tests to verify the functionality of the notification screen. profile/: Tests centered on user profile management, and updating personal details. sign_in/: Tests for the sign-in screen, focusing on logging in and error handling. sign_up/: Tests for the sign-up screen, ensuring registration is working as expected.Writing Tests for Each ScreenLet’s dive deeper into crafting a sample test for the dashboard screen. This test suite will encompass various tests to ensure that essential elements are displayed correctly, including the Dashboard title, key transfer functions such as Deposit, Withdraw, Send, and Request, as well as the transaction history components.dashboard_test.dartimport 'package:flutter/material.dart'; import 'package:flutter_test/flutter_test.dart'; import 'package:patrol/patrol.dart'; import 'package:richpay_app/main.dart' as app; void main() { patrolTest( 'Dashboard Screen - Verify the elements on the dashbaord', ($) async { // Start the app app.main(); await $.pumpAndTrySettle(); final welcomeSignInButton = $(find.byKey(const Key('sign_in_btn'))); await $(welcomeSignInButton).tap(); await $.pumpAndSettle(); // // Verify the presence of email/username input field and enter text final emailTextBox = $(find.byKey(const Key('email_username'))); await $(emailTextBox).enterText('test@gmail.com'); final passwordTextBox = $(find.byKey(const Key('password'))); await $(passwordTextBox).enterText('test123'); final signInSignInButton = $(find.byKey(const Key('sign_in_btn'))); await $(signInSignInButton).tap(); // Wait for the navigation to complete after sign-in await $.pumpAndSettle(); // Add further assertions if needed expect(find.text('Dashboard'), findsOneWidget); expect(find.text('Deposit'), findsAtLeast(1)); expect(find.text('Withdraw'), findsOneWidget); expect(find.text('Send'), findsOneWidget); expect(find.text('Request'), findsOneWidget); expect(find.text('Transactions History'), findsOneWidget); }, ); } Naming Conventions and Test FlowUsing consistent naming conventions is essential. Screen directories and test files should be named based on the screens they test. This eliminates confusion, especially as your test suite grows. For example: Patrol Test Based On Screen dashboard_test.dart: Tests related to the dashboard screen. profile_test.dart: Tests related to the profile screen.When writing these tests, ensure that: 1 Self Contained 2 Descriptive Test Names Each test is self-contained: A test should not rely on another test. This enhances the modularity of your test suite.Each test function should clearly describe the functionality being tested, such as verify_profile_update or test_sign_up_with_invalid_credentials. Running Tests by DirectoryPatrol allows you to run tests for a specific directory if you want to focus on tests for a particular screen. Here’s how to run tests for the sign_in screen using the CLI:Run all test in ‘sign_in’ directorypatrol test -t integration_test/e2e/sign_in/ Running Patrol Test Sign In Screen Directory Tip: Running On IOS?If you’re running your Patrol test on an iOS device, make sure to pass the -d flag followed by the device’s UDID. This ensures that the correct device is targeted and avoids any running issues that could occur if it’s omitted. For example:Using the Device Flag For iOSpatrol test -d D76D6C18-03AE-46E0-A732-C46608EBF212 -t integration_test/e2e/sign_inIn this command, D76D6C18-03AE-46E0-A732-C46608EBF212 is the UDID of your iOS device, and the -t flag is used to specify the test file, such as integration_test/e2e/sign_in.This command will execute all tests within the sign_in directory, making it easy to target specific areas of the app without running the entire test suite.ConclusionOrganizing test suites by screen name in Patrol helps maintain clean, efficient, and scalable test cases. By creating screen-specific directories, you enhance collaboration and streamline the testing process. This structure becomes especially helpful as your app grows and new features are added. Following this organization strategy ensures that your tests are well-structured, easy to manage, and scalable for future updates.In the next lesson, we’ll dive deeper into Organizing Test Suites by Screen Name in Patrol, where you’ll learn how to effectively categorize your tests and maintain a robust testing workflow. Advanced and Native Interactions in Patrol In the realm of mobile testing, achieving seamless user interactions is paramount to ensuring a smooth user experience. Patrol Testing provides an effective framework for automating and validating these interactions, including both advanced and native functionalities. This guide explores the intricacies of advanced and native interactions in Patrol, offering insights into best practices, techniques, and methodologies to elevate your testing strategies.Advanced InteractionsAdvanced interactions in Patrol Testing encompass a variety of user actions that simulate complex user behaviors. These interactions are crucial for ensuring that applications function as intended in real-world scenarios. Here are some key types of advanced interactions:GesturesGestures such as swipes, pinches, and rotations play a crucial role in navigating and interacting with mobile applications. These gestures simulate the natural user interactions within an app, and automating them ensures your tests closely mimic real-world usage scenarios. Patrol makes it easy to automate gestures with its intuitive syntax, allowing testers to seamlessly simulate complex interactions such as swipes.Swipe Left// Verify the first card is visible initially expect(find.byType(CardWidget), findsWidgets); // Swipe left to scroll right through the cards await $.tester.drag(find.byType(CarouselSlider), const Offset(-300, 0)); await $.pumpAndSettle();A left swipe action mimics the user’s gesture of dragging the screen to the left, often used to reveal the next set of items in a carousel or slider. Swiping Left in Patrol Card Verification: The test first checks if the CardWidget is visible. Swipe Action: The swipe is performed by dragging the CarouselSlider with an offset of -300 on the X-axis, which simulates a leftward swipe. Settling: After the swipe, we call await $.pumpAndSettle(); to allow the animations or transitions to complete.Swipe Right// Verify the first card is visible initially expect(find.byType(CardWidget), findsWidgets); // Swipe right to scroll right through the cards await $.tester.drag(find.byType(CarouselSlider), const Offset(300, 0)); await $.pumpAndSettle();Similarly, a right swipe mimics the user’s gesture of dragging the screen to the right, often to scroll back to the previous items in the carousel. Swiping Right in Patrol Card Verification: The test first checks if the CardWidget is visible. Swipe Action: The swipe is performed by dragging the CarouselSlider with an offset of 300 on the X-axis, which simulates a rightward swipe. Settling: After the swipe, we call await $.pumpAndSettle(); to allow the animations or transitions to complete.Double TapCertain functionalities depend on double tap actions. Patrol currently doesn’t have built-in method for doubleTapping on an element. In this scenario we will use the tap feature twice. Tip: Double Tap in Patrol TestingPatrol doesn’t have a built-in doubleTap method for interacting with Flutter widgets in the app. However, Patrol provides a $.native.doubleTap feature, which is specifically used for WebViews and elements that are native to the device itself, rather than elements within the Flutter app. To simulate a double-tap in a Flutter app, you can manually call tap twice with a small delay in between.Double Tapawait $.tap(find.text('Double Tap for App Info')); await $.tap(find.text('Double Tap for App Info')); expect(find.text('Rich Pay v2.0.0 | Patrol Version 3.2.0'), findsOneWidget);This command allow you to validate double taps and the expectation ensuring comprehensive coverage of user actions. Mimicking DoubleTap FeatureNative InteractionsNative interactions refer to the ability to interact with platform-specific features and components, significantly enhancing the overall user experience by testing your application in real-world scenarios. Patrol provides robust support for accessing and interacting with native functionalities on both Android and iOS devices. This feature allows testers to simulate device-level interactions, ensuring that applications behave correctly under various system conditions.Accessing Device FeaturesPatrol allows you to interact with several native device features, such as WiFi, GPS, dark mode, and system dialogs. These interactions are invaluable for testing how your app reacts to changes in device settings or permissions. For instance, when testing a weather app that relies on location services, you can simulate turning GPS on and off, or granting and denying location permissions.Below is a sample code that demonstrates how you can access and manipulate some of these native features:Native FeaturespatrolTest('demo', (PatrolIntegrationTester $) async { await $.pumpWidgetAndSettle(AwesomeApp()); // prepare network conditions await $.native.enableCellular(); await $.native.disableWifi(); // toggle system theme await $.native.enableDarkMode(); // handle native location permission request dialog await $.native.selectFineLocation(); await $.native.grantPermissionWhenInUse(); // tap on the first notification await $.native.openNotifications(); await $.native.tapOnNotificationByIndex(0); });Interacting with Native Alerts and DialogsMany applications utilize native alerts and dialogs for user notifications or confirmations. Patrol can handle these interactions effectively:System Dialog > Grant Permissionif (await $.native.isPermissionDialogVisible()) { await $.native.grantPermissionWhenInUse(); } Patrol Grant Access To System PromptThis sequence ensures that your tests can manage alerts, providing a seamless user experience.ScrollingTesting native scrolling is crucial for applications with long lists or multiple screens. Patrol facilitates these actions with simple commands:scrollToawait $(find.byKey(Key('request-tab'))).tap(); await $.pumpAndSettle(); await $(find.text('CONTINUE')).scrollTo(); await $(find.text('CONTINUE')).tap(); Patrol ScrollTo FeatureInteracting with WebViewsWebViews are a common element in mobile applications, allowing developers to display web content within a native app. Testing WebViews can be challenging due to the mixed nature of web elements inside a native container, but Patrol provides efficient ways to interact with them. This guide will walk you through testing WebView elements using Patrol, ensuring your app’s web interactions work seamlessly.WebViews// Tap on the button that opens the WebView page await $(find.text('Open Web Page')).tap(); // Allow the WebView to load by waiting and trying to settle for 15 seconds await $.pumpAndTrySettle(timeout: Duration(seconds: 15)); // Enter name into the first text input field (index 0) await $.native.enterTextByIndex( 'John Smith', index: 0, // Adjust index based on your specific form structure keyboardBehavior: KeyboardBehavior.alternative, ); // Enter email into the second text input field (index 1) await $.native.enterTextByIndex( 'student@masteringqa.com', index: 1, // Adjust index based on your specific form structure keyboardBehavior: KeyboardBehavior.alternative, ); // Enter password into the third text input field (index 2) await $.native.enterTextByIndex( 'test1234', index: 2, // Adjust index based on your specific form structure keyboardBehavior: KeyboardBehavior.alternative, ); Patrol Interacting With WebViewsPatrol uses the enterTextByIndex function to simulate typing text into specific input fields in the WebView. The index parameter specifies the position of the field within the WebView. The KeyboardBehavior.alternative parameter allows you to manage how the keyboard behaves during interactions, this is very crucial when working with IOS devices.Best Practices for Advanced and Native Interactions Use Assertions Wisely: Always validate expected outcomes after performing interactions. For instance, after a swipe action, assert that the correct screen is displayed or that the expected element is visible. Maintain Readable Code: Write clear and maintainable test scripts. Using descriptive names for actions and elements helps other team members understand your tests. Leverage Wait Commands: Utilize wait commands effectively to ensure that your tests are resilient to timing issues. Implementing proper waits between actions minimizes false negatives. Combine Interactions: Test complex user scenarios by combining multiple interactions. For example, you might simulate a user logging in, then navigating to a profile page and updating details.ConclusionMastering advanced and native interactions in Patrol Testing is essential for delivering high-quality mobile applications. By utilizing Patrol’s capabilities to simulate user behaviors and engage with native features, you can ensure a seamless user experience. Adopting the best practices in this guide will help you create effective and maintainable tests for comprehensive application validation.

Pixel 7 Emulator LaunchedConclusionWith your emulator set up, you can now test your applications in a virtual environment. The next step involves installing APK apps on your emulator for testing purposes. Proceed to Installing an APK app on an Android Emulator to continue your journey. Installing an APK app on an Android Emulator After setting up your Android emulator, the next step is to install and test APK applications on it. This guide will walk you through the process of installing an APK on your emulator.Installing App via Project ViewWith your emulator up and running, it’s time to fire up your app! Go back to Android Studio and click on the green play button in the toolbar or from the menu bar, select Run . Android Studio will build your app and install it on the emulator. Installing App On EmulatorOnce the installation process is complete, your app will automatically launch on the emulator. App Installed SuccessfullyInstalling Your App via APKAnother method to installing an app on your emulator would be through an apk file. To add an apk to your device simply navigate to location of your apk or download an apk file from a trusted source online. For this example I will be using the same apk generated after building the app from the project. Since I’m using Flutter project to build this app, the location of the apk is here App Project build app outputsflutter-apkapp-debug.apk Build Location of the APK FileOnce you locate your apk, simply drag and drop the apk onto the emulator for it to install. Installing APK By Dragging & Dropping On EmulatorConclusionVoila! Your app is now running on the emulator. Take some time to explore its features and functionalities. Click around, interact with different elements, and get a feel for how it behaves. Next, we’ll explore how to use ADB with Android emulators to perform various debugging tasks. Head over to Using ADB with Android Emulators for more insights. Using ADB with Android Emulators Previously, we covered installing APK apps on your emulator. Now, let’s delve into using ADB (Android Debug Bridge) with Android emulators. ADB is a powerful command-line tool that enables communication with your emulator or device.

Use this command.bashadb install /Users/{UserName}/Desktop/test-apps/app-debug.apk Installing An APK Using ADB CommandGet Android Package Name: Get the name of the Android app’s package name in order to use the uninstall command later. With the test app lauched on the emulator, open a new terminal and enter this command below:bashadb shell dumpsys window | grep 'mCurrentFocus' Name of App Package & Main ActivityUninstall an APK: Remove an application from the emulator.bashadb uninstall com.example.yourapp Uninstalling APK Using ADB CommandConclusionThe ADB is an essential tool for Android development and debugging. Mastering its commands will enhance your ability to manage and debug your applications effectively. Up next, we’ll cover automating UI tests on Android emulators, a crucial step for ensuring your app’s usability. Continue to Automating UI Tests on Android Emulators for detailed instructions. Automating UI Tests on Android Emulators Building on our knowledge of ADB, this guide focuses on automating UI tests on Android emulators. Automated UI tests ensure that your application’s user interface behaves as expected across different scenarios and devices.Why Automate UI Tests?Automated UI tests save time and resources by running tests that simulate user interactions. They help identify bugs and inconsistencies in the UI, providing a reliable way to maintain high-quality applications.Setting Up Espresso for UI TestingAdd DependenciesYou need to add Espresso and other related dependencies in your build.gradle file of your Android app module (app/build.gradle).android/app/build.gradle defaultConfig { testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner" }Create a Test Class In src/androidTest/java and call it MainActivityTest.This test will ensure that the app is launched and ready for interaction. The test method will simulate a user clicking the plus button and verifies the resulting UI state.MainActivityTest.class@RunWith(AndroidJUnit4.class) @LargeTest public class MainActivityTest {@RunWith(AndroidJUnit4.class): This annotation tells JUnit to run the test class using the AndroidJUnit4 test runner. This runner provides compatibility with Android components and manages the test lifecycle.@LargeTest: This annotation classifies the test as a “large” test. Large tests typically involve integration testing, where multiple components of the application are tested together.MainActivity.class@Rule public ActivityScenarioRule<MainActivity> activityRule = new ActivityScenarioRule<>(MainActivity.class); @Rule public DisableAnimationsRule disableAnimationsRule = new DisableAnimationsRule();@Rule: Rules in JUnit are used to add or extend the behavior of each test method in a test class. They provide additional functionality before and after each test is run.ActivityScenarioRule<MainActivity> activityRule: This rule launches the specified activity (MainActivity in this case) before each test and closes it after each test. It provides a simplified way to test activities. The ActivityScenarioRule starts and stops the activity and also ensures that the activity is running before the test begins.DisableAnimationsRule disableAnimationsRule: This custom rule is used to disable system animations during the test run. Animations can interfere with Espresso tests by causing unexpected delays or timing issues, so disabling them ensures more consistent test results.MainActivity.class@Test public void testClickPlusButton() throws InterruptedException { // Click the plus button to open the AddEditTaskActivity onView(withId(R.id.fab)).perform(click()); // Verify that the AddEditTaskActivity is displayed by checking for the presence of the title EditText onView(withId(R.id.titleEditText)).check(matches(withText(""))); }@Test: This annotation indicates that the following method is a test method. JUnit will execute this method as a test case.public void testClickPlusButton(): This is the test method. The method name typically describes what is being tested. In this case, it tests the behavior of clicking the plus button.onView(withId(R.id.fab)).perform(click());: This line uses Espresso to interact with the UI. It finds a view with the ID fab which is the floating action button in this app and performs a click action on it. Espresso’s onView method is used to find views in the current activity’s layout, and perform is used to execute actions on those views.onView(withId(R.id.titleEditText)).check(matches(withText("")));: This line verifies that a view with the ID titleEditText is displayed and that its text is empty. This check is used to confirm that the AddEditTaskActivity is displayed by looking for the presence of an empty title EditText. The check method is used to perform assertions on views, and matches verifies that the view’s state matches the specified condition. Since this is a ToDo app, let’s enhance the test suite by adding two more critical scenarios: one for adding a task and another for deleting a task. These scenarios will ensure that the core functionalities of creating and removing tasks are working as expected.MainActivity.class@Test public void testAddTask() throws InterruptedException { // Click the plus button to open the AddEditTaskActivity onView(withId(R.id.fab)).perform(click()); // Enter text into the title and description fields and close the keyboard onView(withId(R.id.titleEditText)) .perform(typeText("New Task Title"), closeSoftKeyboard()); onView(withId(R.id.descriptionEditText)) .perform(typeText("New Task Description"), closeSoftKeyboard()); // Click the save button onView(withId(R.id.saveButton)).perform(click()); // Verify that the new task is displayed onView(withText(endsWith("New Task Title"))) .check(matches(isDisplayed())); } @Test public void testDeleteTask() throws InterruptedException { // Delete the task onView(withId(R.id.doneButton)).perform(click()); Thread.sleep(2000); // Verify that the task is deleted by checking that the item is not in the list onView(withText(endsWith("Task to Delete"))).check(doesNotExist()); Thread.sleep(2000); }Running UI TestsClick on the green play icon next to the class definition to run all tests in the class. Alternatively, click on the green play icon next to individual test methods to run specific tests. Running Android UI TestViewing Test Results Once the tests start running, the Run window will display the progress and results. The Run window shows which tests passed or failed, along with detailed logs and stack traces for any failures.Analyze Test Results Green checkmarks indicate passed tests. Red X marks indicate failed tests, with details about the failure. Yellow warning signs indicate ignored or skipped tests. Reviewing Expresso Test ResultsConclusionAutomating UI tests with Espresso provides a robust way to ensure your app’s user interface functions correctly. Next, we’ll explore performance testing on Android emulators, which is vital for optimizing your app’s performance. Proceed to Performance Testing on Android Emulators for more information. Performance Testing on Android Emulators Having covered UI testing, we now turn to performance testing on Android emulators. Performance testing helps identify bottlenecks and ensures your application runs smoothly under various conditions.Performance TestingPerformance testing is crucial for delivering a responsive and efficient app. It helps detect issues related to memory usage, CPU load, and network performance, ensuring a seamless user experience.Using Android Profiler Open Android Profiler - In Android Studio, navigate to: View > Tool Windows > Profiler or you can click the Profiler icon in the bottom toolbar. Android Studio Profiler Select an Emulator: Choose the emulator or device to profile. If your device is already running, it will automatically use that device.

To locate the id element or other useful selectors, ensure that the emulator or device is booted up. First, launch the Appium Server and Inspector. Open the Appium Desktop Server and click the startServer button. Next, launch the Appium Inspector, making sure that the server port matches the Appium server’s port.

In the preview window, locate and click on the element for which you want to retrieve attributes. For the purposes of this guide, we will click on the Add Task button. By doing so, the attributes related to this specific element will be displayed, allowing you to inspect and utilize them as needed. Appium Inspector Viewing The Element's Properties The accessibility id: value is to Add Task The id: value is to com.example.todoapp:id/fab The xpath: value is to //android.widget.ImageButton[@content-desc="Add Task"]You have the flexibility to use any available selector, but for this guide, we will select the second option, which represents the id attribute with the value com.example.todapp:id/fab. This value will be used in our code. Close the Appium Inspector Session to free up the Appium Server 4273 port.Copy this id value and navigate to the FirstAppiumTest class in your project. Find the element designated for adding a task and paste the copied id value into the addTaskButton element. This ensures that our test script can correctly interact with the element.

Yay! In the FirstAppiumTest class, right-click to open the context menu. Navigate to Run As and select Java Application. Now, sit back and watch as your script takes off for the first time! If everything goes well, you will see TEST PASSED in the console. Appium Run As Java ApplicationAnalyze the Test ResultsAfter the test execution is complete, review the results to ensure your test case ran successfully. Later in this series, we will learn how to implement TestNG to organize tests based on industry standards. Test Results - Passed Running Appium Test ScriptConclusionYou have now learned how to perform basic UI testing with Appium. This includes finding elements and performing actions. In the next guide, we’ll take a closer look at Organizing Multiple Test Scenarios In Appium with TestNG. Organizing Multiple Test Scenarios in Appium Using TestNG In the dynamic world of mobile application testing, managing and organizing multiple test scenarios efficiently is crucial for ensuring robust and reliable testing. Appium, combined with TestNG, provides a powerful framework to achieve this. This guide will walk you through the process of organizing multiple test scenarios in Appium using TestNG, leveraging the power of Java. Whether you’re a beginner or an advanced user, this comprehensive guide will help you streamline your test automation process and enhance your testing capabilities. We will be using the project we setup previously. Setting Up Maven ProjectLet’s navigate to the pom.xml file so we can add the TestNG dependency. We’ll be using TestNG version 7.1.0 for our project. Adding TestNG Dependency To pom.xmlTestNG Dependency (pom.xml)<dependency> <groupId>org.testng</groupId> <artifactId>testng</artifactId> <version>7.1.0</version> <scope>compile</scope> </dependency>By adding the TestNG dependency to your Maven project, you now have the necessary annotations to write and execute TestNG tests within the Appium project.Creating TestNG Class Let’s head back to our directory /src/test/java/com/test/ where we’ll create a copy of the existing FirstAppiumTest class. We’ll then rename this copy to FirstAppiumTestNG to begin restructuring the test to support TestNG. This new class will serve as our foundation for integrating TestNG functionalities. Copying FirstAppiumTest Class Pasting FirstAppiumTest Class Rename Copied File to FirstAppiumTestNGImporting TestNG AnnotationsIn the newly created FirstAppiumTestNG class, begin by importing the necessary TestNG annotations. These will include @BeforeClass, @AfterClass, and @Test.FirstAppiumTestNG.classimport org.testng.annotations.AfterClass; import org.testng.annotations.BeforeClass; import org.testng.annotations.Test; The @BeforeClass annotation will be used to set up the Appium driver before any tests are run, ensuring that the environment is correctly initialized. Similarly, the @AfterClass annotation will handle the teardown process, cleaning up resources once all tests have been executed. The @Test annotation will be applied to individual test methods, marking them as TestNG test cases.Modifying Class To Support TestNGSo what we’re going to do is remove the main() function call and close the curly bracket from our initial setup. Next, we will create a new public static AndroidDriver variable called driver. BeforeClassIn the @BeforeClass method, we will move the Desired Capabilities setup into the setup() function. This approach ensures that our Appium driver is properly configured before any tests are execute. Moving Desired Capabilities To BeforeClass MethodTest MethodIn the @Test method, we will add our simple test case from the previous guide, which is to click the Add Task button. This test will validate that our application responds correctly when adding a new task. By organizing our tests this way, we maintain a clear separation of concerns, making our test cases easier to manage and understand. Moving Scenario To Test MethodAfterClass MethodFinally, we’ll move the driver.quit() function into the @AfterClass teardown method. This adjustment ensures that the Appium driver is properly closed after all tests have been executed, cleaning up any resources used during the test run. Moving The Closing of the Driver in AfterClass MethodFirstAppiumTestNG.class (w/ Before & After Methods)package com.test; import io.appium.java_client.android.AndroidDriver; import org.openqa.selenium.By; import org.openqa.selenium.WebElement; import org.openqa.selenium.remote.DesiredCapabilities; import java.io.File; import java.net.MalformedURLException; import java.net.URL; import org.testng.annotations.AfterClass; import org.testng.annotations.BeforeClass; import org.testng.annotations.Test; public class FirstAppiumTestNG { public static AndroidDriver driver; @BeforeClass public void setUp() throws MalformedURLException { File app = new File("src/test/resources/app/app-debug.apk"); // Set the desired capabilities for your test DesiredCapabilities caps = new DesiredCapabilities(); caps.setCapability("deviceName", "emulator-5554"); caps.setCapability("platformName", "android"); caps.setCapability("app",app.getAbsolutePath()); // Initialize the Appium driver driver = new AndroidDriver (new URL("http://127.0.0.1:4273/wd/hub"), caps); } @Test public void clickingAddTaskButton() throws InterruptedException { // Add test case scenario here WebElement addTaskButton = driver.findElement(By.id("com.example.todoapp:id/fab")); addTaskButton.click(); // quick debug wait for 1 seconds Thread.sleep(1000); System.out.println("TEST PASSED!"); } @AfterClass public void tearDown() { if (driver != null) { // Close the driver session driver.quit(); } } }Adding More Test & AssertionsWhy stop here? Next, we’ll add some assertions and create two more test scenarios to highlight the beauty of TestNG running multiple scenarios and validating our expectations. We will create new tests called addingTaskToDoTheList() and deletingTaskFromTheList(), similar to the test we created using Espresso in our Android guides. We will add these methods to our file, and then we should be ready to run our tests.In our first new test scenario, we focus on adding a task to our to-do list. This test begins by clicking the “Add Task” button to navigate to the task addition screen. We verify that the user is on the correct screen by checking the presence of the title input field. Here’s how the implementation looks:Test: clickingAddTaskButton()@Test public void clickingAddTaskButton() throws InterruptedException { // Add test case scenario here WebElement addTaskButton = driver.findElement(By.id("com.example.todoapp:id/fab")); addTaskButton.click(); // quick debug wait for 2 seconds Thread.sleep(2000); WebElement addTaskTitle = driver.findElement(By.id("com.example.todoapp:id/titleEditText")); Assert.assertTrue(addTaskTitle.isDisplayed(), "User is on the Add Task Details Screen"); driver.navigate().back(); Thread.sleep(1000); }addingTaskToDoTheList() TestNext, we have the addingTaskToDoTheList() method, which adds a task to the to-do list. This method clicks the “Add Task” button, enters a title and description for the new task, and then saves it. After saving, it verifies that the new task appears in the task list.Test: addingTaskToDoTheList()@Test public void addingTaskToDoTheList() throws InterruptedException { WebElement addTaskButton, saveButton; WebElement addTaskTitleField, addTaskDescField; // click the Add Task button addTaskButton = driver.findElement(By.id("com.example.todoapp:id/fab")); addTaskButton.click(); // quick debug wait for 2 seconds Thread.sleep(2000); // add title to the task addTaskTitleField = driver.findElement(By.id("com.example.todoapp:id/titleEditText")); addTaskTitleField.click(); addTaskTitleField.sendKeys("Buy Milk"); // add description to the task addTaskDescField = driver.findElement(By.id("com.example.todoapp:id/descriptionEditText")); addTaskDescField.click(); addTaskDescField.sendKeys("Grab 2 Gallons of Milk"); // click the Save button saveButton = driver.findElement(By.id("com.example.todoapp:id/saveButton")); saveButton.click(); // quick debug wait for 2 seconds Thread.sleep(2000); WebElement newTaskAdded = driver.findElement(By.id("com.example.todoapp:id/textView")); Assert.assertEquals(newTaskAdded.getText().toString(), "Buy Milk", "New Task Found"); }deletingTaskFromTheList() TestFinally, we have the deletingTaskFromTheList() method, which tests the deletion of a task from the list. This method locates the delete button and clicks it, then verifies that the task is removed from the task list.Test: deletingTaskFromTheList()@Test public void deletingTaskFromTheList() throws InterruptedException { WebElement deleteButton; // click the Delete button deleteButton = driver.findElement(By.id("com.example.todoapp:id/doneButton")); deleteButton.click(); // quick debug wait for 2 seconds Thread.sleep(2000); Assert.assertTrue(true, "Task is deleted & is removed from the Task List Screen"); }Full ImplementationHere’s the full implementation of the FirstAppiumTestNG file.

In this new file, we’ll add the XML code below to enable running our FirstAppiumTestNG class.TestNG Suite Config (testng.xml)<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd"> <suite name="My First Appium TestNG Test"> <test name="TODO App Automation Testing"> <classes> <class name="com.test.FirstAppiumTestNG"/> </classes> </test> <!-- Test --> </suite> <!-- Suite --> Create A New TestNG File Naming The File testng.xml Pasting The XML Script In The New Testng.xml FileTo properly run our TestNG XML file, we need to configure the pom.xml file accordingly. Start by opening your pom.xml file and locating the Maven Surefire Plugin section. Within this section, you’ll need to add the TestNG configuration. Specifically, scroll down to where you see the <version> tag within the Maven Surefire Plugin and insert the following configuration just below it:TestNG Suite Setup (pom.xml)<configuration> <suiteXmlFiles> <suiteXmlFile>testng.xml</suiteXmlFile> </suiteXmlFiles> <testFailureIgnore>false</testFailureIgnore> </configuration> Pasting TestNG XML ConfigurationThis snippet tells Maven to use the testng.xml file to determine which tests to run. The <testFailureIgnore> tag is set to false, ensuring that the build will fail if any test fails, which is often the desired behavior in a continuous integration environment.Once you’ve added this configuration, make sure to save your pom.xml file. With these changes in place, your project is now ready to run with the specified TestNG configuration. Let's open the Terminal in Eclipse so we can execute the Maven command. Type or copy the command mvn test -DsuiteXmlFile=testng.xml into the Terminal. Press Enter to execute. The script should begin running the three scenarios we created earlier. As the tests execute, you should see passing logs appear in the console, indicating successful execution. Pasting Maven Command To Run TestNG Successful Test Results After Running CommandRunning Test: TestNG PluginAlternatively, if you have the TestNG plugin installed on your IDE, you can simply right-click on the test file and choose Run As TestNG. This method provides a quick and easy way to execute your tests without the need to manually configure the XML file. class. Running Test File Using 'Run As TestNG'Running FirstAppiumTestNG ScriptAlright, let’s sit back and enjoy watching the results. In the video below, you’ll see the script in action as it runs via the mvn command. The test executes all three scenarios and they pass successfully! It’s always a great feeling when everything works perfectly, isn’t it? Yay! GIF: Script Is Running TestNG Results Pane TestNG HTML Web ResultsConclusionOrganizing multiple test scenarios in Appium using TestNG is a critical step in building a robust test automation strategy. With TestNG, we can group our test cases logically, execute them in a specific order, and generate detailed reports. This structured approach not only saves time but also minimizes errors, making our testing process more reliable and efficient. Stay tuned for our next topic, where we will delve into Understanding Appium UI Locators. Understanding Appium UI Locator Strategies In this guide, we will delve into Appium UI Locator Strategies. Understanding how to efficiently locate elements is crucial for creating robust and maintainable automated tests. This guide is designed to be comprehensive and accessible for both beginners and advanced users. By the end of this guide, you’ll be proficient in various locator strategies in Appium, using Java as our code language.Introduction to LocatorsLocators are used to find UI elements on the mobile application. Appium supports various locator strategies: ID - is a unique identifier for elements. It is one of the most reliable and fastest ways to locate elements. Name - is another attribute that can be used, although it's less common and sometimes deprecated. Class Name - locates elements by their class attribute. It can return multiple elements, so it's often used with other strategies. XPath - is a powerful and flexible locator strategy but can be slower and more brittle. It's often used when other locators are not available. iOS Predicate String (iOS) - iOS Predicate String is used for complex queries on iOS. iOS Class Chain (iOS) - iOS Class Chain is another iOS-specific strategy that allows chaining class names and attributes.Using ID Using an id is one of the most efficient ways to identify and capture elements in Appium, provided that this option is available in our inspector. The id attribute serves as a unique identifier for elements within the DOM, allowing for precise and reliable element selection. This method is particularly advantageous because IDs are designed to be unique within a given page, thereby reducing the risk of selecting the wrong element.By.idWebElement taskButton = driver.findElement(By.id("add-task-button"));Using Name By using the name attribute, you ensure your code remains clear and intuitive. This method not only enhances readability but also reduces the risk of errors that can occur with more complex locators. It’s a straightforward way to improve your Appium testing strategy, making it easier to manage and scale your automated tests. Adopting this practice can lead to more robust and reliable test scripts, ultimately contributing to a more efficient development cycle.By.nameWebElement taskButton = driver.findElement(By.name("add-task-button"));Using XPath When using xpath to identify an element in Appium, you can target specific attributes or hierarchical relationships within the UI structure. For example, you might want to locate a button based on its ID, class, or even its position relative to other elements. This flexibility is one of the key advantages of using xpath over other locating strategies.By.xpathWebElement taskButton = driver.findElement(By.xpath("//android.widget.Button[@content-desc='SIGN IN']"));Using Class Name You can capture and interact with an element by specifying its className. This method is particularly useful when elements share common characteristics or belong to the same class.By.classNameWebElement taskButton = driver.findElement(By.className("android.widget.Button"));[IOS] iOS Predicate StringThis technique offers a precise way to locate elements based on specific attributes. The iOS Predicate String is a powerful tool that leverages the NSPredicate class from Apple’s iOS development environment, allowing developers to create complex queries for UI elements.[IOS] iOS Class Chain This approach leverages the class chain strategy, providing a powerful alternative to traditional locator strategies. By utilizing iOSClassChain, developers can efficiently target elements based on their hierarchical structure, enhancing the precision of their UI automation tests.By.iOSClassChainWebElement taskButton = driver.findElement(By.iOSClassChain("**/XCUIElementTypeButton[`label == 'Task'`]"));ConclusionIn this guide, we explored various Appium UI locator strategies using Java. By mastering these locators, you can write efficient and reliable automated tests for your mobile applications. Remember to prioritize IDs and Accessibility IDs for their reliability and speed, and use XPath judiciously. Stay tuned for our next topic, where we will dive into Advanced Automating Gestures in Appium. Automating Gesture Actions in Appium In the previous guide, we learned about Appium UI Locator Strategies. Now, let’s take it a step further by automating gesture actions. Gestures such as swipes, scrolls, and taps are essential for comprehensive mobile app testing.Common Gesture ActionsAlright, let’s dive into Gesture Actions in Appium. These actions are essential for simulating complex interactions with your mobile app, mimicking how a real user would engage with it. Whether you need to swipe, pinch, zoom, or perform a drag-and-drop action, Appium’s gesture commands have you covered. These gestures are critical for testing user interfaces that rely heavily on touch interactions, ensuring your app behaves as expected in the hands of actual users.Create Gestures Util ClassLet’s dive right in and enhance our Appium project by adding a new class to handle gesture methods efficiently. To begin, we’ll create a new class called GesturesUtil which will serve as a repository for various gesture methods. This step is essential to keep our code organized and maintainable. First, navigate to your project directory and create a new package namedcom.helpers. This package will be the home for our GesturesUtilclass. Organizing your code into packages not only improves readability but also aligns with best practices in software development, making your project more modular and easier to manage.Import DependenciesIn the com.helpers package, create the GesturesUtil class. This class will encapsulate all the gesture methods you need for your Appium tests, such as swipe, tap, and scroll. To get started, the first step is importing the necessary dependencies. In your project, add the following imports:GesturesUtil.classimport io.appium.java_client.AppiumDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.interactions.PointerInput; import org.openqa.selenium.interactions.Sequence; import java.time.Duration; import java.util.Arrays; import java.util.Collections;With these imports in place, you can now proceed to define your gesture methods without encountering any compilation issues. This setup ensures that your code is well-structured and ready to handle a variety of automated testing scenarios, making your Appium testing framework robust and efficient.Simulating Tap or Long Press A tap is simply a quick touch on the screen, often used for selecting items, while a long press involves holding down on an element for a longer duration. This is typically used for actions like bringing up a context menu or initiating a special function. Appium’s capabilities allow you to simulate both, ensuring that these interactions are tested thoroughly.Gesture: tapElementpublic void tapElement(WebElement element) { PointerInput finger = new PointerInput(PointerInput.Kind.TOUCH, "finger"); Sequence tap = new Sequence(finger, 1) .addAction(finger.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), element.getLocation().x + element.getSize().width / 2, element.getLocation().y + element.getSize().height / 2)) .addAction(finger.createPointerDown(PointerInput.MouseButton.LEFT.asArg())) .addAction(finger.createPointerUp(PointerInput.MouseButton.LEFT.asArg())); driver.perform(Collections.singletonList(tap)); }TapThe tapElement method simulates a tap on a web element by: Creating a touch input named finger. Creating a sequence of actions that: - Moves the touch pointer to the center of the specified element. - Presses down on the element. - Releases the press. Perform the sequence of actions using the driver.Gesture: Long Presspublic void longPressElement(WebElement element, Duration duration) { PointerInput finger = new PointerInput(PointerInput.Kind.TOUCH, "finger"); Sequence longPress = new Sequence(finger, 1) .addAction(finger.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), element.getLocation().x + element.getSize().width / 2, element.getLocation().y + element.getSize().height / 2)) .addAction(finger.createPointerDown(PointerInput.MouseButton.LEFT.asArg())) .addAction(finger.createPointerMove(duration, PointerInput.Origin.viewport(), element.getLocation().x,element.getLocation().y)) .addAction(finger.createPointerUp(PointerInput.MouseButton.LEFT.asArg())); driver.perform(Collections.singletonList(longPress)); }Long PressThe longPressElement method simulates a long press on a mobile or web element by: Moving the virtual finger to the center of the element. Pressing down on the element. Holding the press for a specified duration. Releasing the press.Simulating Swipe GesturesIn Appium, swiping is straightforward but powerful, allowing you to simulate the user’s finger moving across the screen.To implement a swipe, you define the start and end coordinates, which tells Appium where the swipe should begin and end. By fine-tuning these coordinates, you can create swipes that mimic natural user behavior, ensuring your test cases are as realistic as possible.Gesture: Swipepublic void swipe(int startX, int startY, int endX, int endY, Duration duration) { PointerInput finger = new PointerInput(PointerInput.Kind.TOUCH, "finger"); Sequence swipe = new Sequence(finger, 1) .addAction(finger.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), startX, startY)) .addAction(finger.createPointerDown(PointerInput.MouseButton.LEFT.asArg())) .addAction(finger.createPointerMove(duration, PointerInput.Origin.viewport(), endX, endY)) .addAction(finger.createPointerUp(PointerInput.MouseButton.LEFT.asArg())); driver.perform(Collections.singletonList(swipe)); }SwipeThe swipe function simulates a swipe gesture on a touch screen. First, it moves the touch pointer from a starting point (startX, startY) Next it moves to the ending point (endX, endY) over a given duration. The process involves moving the pointer to the start position, touching down, moving to the end position, and then lifting up All of these actions are coordinated through a sequence of actions performed by the driver.Simulating a Zoom InNext we have pinch and zoom gestures, which are indispensable for applications that involve maps, images, or any form of visual content that users might need to zoom in and out of.Gesture: Zoom Inpublic void zoomIn(WebElement element) { int centerX = element.getLocation().getX() + element.getSize().getWidth() / 2; int centerY = element.getLocation().getY() + element.getSize().getHeight() / 2; int endX1 = centerX - 100; int endY1 = centerY - 100; int endX2 = centerX + 100; int endY2 = centerY + 100; PointerInput finger1 = new PointerInput(PointerInput.Kind.TOUCH, "finger1"); Sequence pinch1 = new Sequence(finger1, 1) .addAction(finger1.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), centerX, centerY)) .addAction(finger1.createPointerDown(PointerInput.MouseButton.LEFT.asArg())) .addAction(finger1.createPointerMove(Duration.ofMillis(600), PointerInput.Origin.viewport(), endX1, endY1)) .addAction(finger1.createPointerUp(PointerInput.MouseButton.LEFT.asArg())); PointerInput finger2 = new PointerInput(PointerInput.Kind.TOUCH, "finger2"); Sequence pinch2 = new Sequence(finger2, 1) .addAction(finger2.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), centerX, centerY)) .addAction(finger2.createPointerDown(PointerInput.MouseButton.LEFT.asArg())) .addAction(finger2.createPointerMove(Duration.ofMillis(600), PointerInput.Origin.viewport(), endX2, endY2)) .addAction(finger2.createPointerUp(PointerInput.MouseButton.LEFT.asArg())); driver.perform(Arrays.asList(pinch1, pinch2)); }PinchingPinching involves bringing two fingers together on the screen, while zooming involves spreading them apart. Appium handles these multi-touch gestures by specifying the touch points and their movements, giving you precise control over the interactions. Calculate the center coordinates (centerX, centerY)of the element. Define end coordinates for the pinch gesture (endX1, endY1, endX2, endY2). Create the first finger input sequence pinch1to: - Move to the center of the element. - Press down. - Move to the end coordinates over 600 ms. - Lift up the finger. Create the seond finger input sequence pinch2 to: - Move to the center of the element. - Press down. - Move to the end coordinates over 600 ms. - Lift up the finger. Execute both sequences simultaneously to perform the pinch gesture.Simulating a Zoom OutPerform a zoom out gesture by reversing the pinch gesture:Gesture: Zoom Outpublic void zoomOut(WebElement element) { int centerX = element.getLocation().getX() + element.getSize().getWidth() / 2; int centerY = element.getLocation().getY() + element.getSize().getHeight() / 2; int startX1 = centerX - 100; int startY1 = centerY - 100; int startX2 = centerX + 100; int startY2 = centerY + 100; PointerInput finger1 = new PointerInput(PointerInput.Kind.TOUCH, "finger1"); Sequence pinchIn1 = new Sequence(finger1, 1) .addAction(finger1.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), startX1, startY1)) .addAction(finger1.createPointerDown(PointerInput.MouseButton.LEFT.asArg())) .addAction(finger1.createPointerMove(Duration.ofMillis(600), PointerInput.Origin.viewport(), centerX, centerY)) .addAction(finger1.createPointerUp(PointerInput.MouseButton.LEFT.asArg())); PointerInput finger2 = new PointerInput(PointerInput.Kind.TOUCH, "finger2"); Sequence pinchIn2 = new Sequence(finger2, 1) .addAction(finger2.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), startX2, startY2)) .addAction(finger2.createPointerDown(PointerInput.MouseButton.LEFT.asArg())) .addAction(finger2.createPointerMove(Duration.ofMillis(600), PointerInput.Origin.viewport(), centerX, centerY)) .addAction(finger2.createPointerUp(PointerInput.MouseButton.LEFT.asArg())); driver.perform(Arrays.asList(pinchIn1, pinchIn2)); }ZoomingPinching involves bringing two fingers together on the screen, while zooming involves spreading them apart. Appium handles these multi-touch gestures by specifying the touch points and their movements, giving you precise control over the interactions. Calculate the center coordinates of the element. Define starting points for two touch actions, positioned diagonally around the center. Create a touch action sequence for the first finger, moving from the starting point to the center. Create a touch action sequence for the second finger, moving from the starting point to the center. Execute both sequences simultaneously to perform the pinch-in gesture.ConclusionIncorporating gesture actions into your Appium tests enhances functionality and verifies a seamless user experience. By simulating real user gestures, you can uncover issues that traditional testing may miss, leading to a more robust and user-friendly app.Whether you’re testing a simple or complex app, mastering these gestures will improve your testing outcomes. In the next guide, you’ll learn about Capturing Screenshots and Logs in Appium. Capturing Screenshots and Logs In Appium Capturing screenshots and logs during your tests is crucial for diagnosing issues, verifying UI elements, and ensuring your app behaves as expected. Screenshots provide visual evidence, while logs offer detailed information about the app’s behavior, network requests, errors, and more.Create New Utils ClassLet’s begin by creating a new Utils class, which will be instrumental in managing your screenshot captures and logging methods. To start, navigate to your project and create a new class within the com.helpers package, or alternatively, any directory that suits your organizational preferences. Creating A New Utils ClassUtils.classpackage com.helpers; import org.openqa.selenium.OutputType; import org.openqa.selenium.TakesScreenshot; import org.openqa.selenium.WebDriver; import org.openqa.selenium.logging.LogEntry; import org.openqa.selenium.io.FileHandler; import org.openqa.selenium.logging.LogEntries; import org.openqa.selenium.logging.LogType;Capturing ScreenshotsTo capture screenshots in Appium using Java, you can use the getScreenshotAs method. Utils.classpublic class Utils { public static void captureScreenshot(WebDriver driver, String fileName) { File srcFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE); try { FileHandler.copy(srcFile, new File("./target/screenshots/" + fileName + ".png")); } catch (IOException e) { e.printStackTrace(); } } It’s important to organize your project structure effectively. To achieve this, we’ll create a dedicated /screenshots directory within the target folder of your project. This organization ensures that all screenshots are stored in a centralized location, making them easy to locate and manage. Creating A New Screenshots Directory For instance, when you capture a screenshot during the automation process, you can save it in this newly created directory. To maintain clarity and avoid confusion, it's essential to give each screenshot file a descriptive name. In this particular example, we will name the screenshot file add_new_task_screen.In this particular example, we will name the screenshot file add_new_task_screen. This naming convention not only helps in identifying the context of the screenshot quickly but also enhances the overall readability and maintainability of your test reports.Call this method in your test script where you want to capture the screenshot: Test: clickingAddTaskButton()@Test public void clickingAddTaskButton() throws InterruptedException { // Add test case scenario here WebElement addTaskButton = driver.findElement(By.id("com.example.todoapp:id/fab")); addTaskButton.click(); // quick debug wait for 2 seconds Thread.sleep(2000); WebElement addTaskTitle = driver.findElement(By.id("com.example.todoapp:id/titleEditText")); Assert.assertTrue(addTaskTitle.isDisplayed(), "User is on the Add Task Details Screen"); Utils.captureScreenshot(driver, "add_new_task_screen"); driver.navigate().back(); Thread.sleep(1000); }When executing your script in Appium, the captured screenshot is stored in the /target/screenshot/ directory. To view the newly captured screenshot, you will need to refresh your project. Once refreshed, the file named add_new_task_screen will appear in the screenshots directory. This step is crucial for verifying that your automation scripts are correctly capturing the visual output you expect. GIF: Reviewing Screenshot Image After Executing TestCapturing LogsTo capture logs in Appium using Java, you can use the getLog method. Here’s how:Test: captureLogs()public static void captureLogs(WebDriver driver) { LogEntries logEntries = driver.manage().logs().get(LogType.BROWSER); for (LogEntry entry : logEntries) { System.out.println(entry.getMessage()); } }Call this method in your test script to capture and print the logs: JavaUtils.captureLogs(driver);Troubleshooting Permission Issues: Ensure your script has write permissions to the directory where screenshots and logs are saved. Driver Compatibility: Make sure the Appium driver versions are compatible with your testing framework and mobile OS. Error Handling: Implement error handling in your scripts to manage exceptions during screenshot or log capture.Best Practices Organize Screenshots: Save screenshots with meaningful names and organize them in folders based on test cases or test runs. Log Levels: Use different log levels (e.g. INFO, DEBUG, ERROR) to filter logs effectively. Automate Log Analysis: Consider automating log analysis to highlight errors or warnings. Periodic Captures: Capture screenshots and logs periodically during long test runs to monitor app behavior over time.ConclusionBy now, you should know how to capture screenshots and logs during your Appium test executions. This knowledge will significantly enhance your ability to debug and report on your tests. Continue honing your skills and exploring more advanced topics in Appium and QA testing. Happy testing!

Articles Introduction to Cucumber and Gherkin Setting Up Cucumber in Your Project Writing Your First Gherkin Feature File Scenario Outlines and Examples Implementing Step Definitions Understanding Cucumber Tags Understanding Cucumber Hooks Running Cucumber Tests & Generating Reports Introduction to Cucumber and Gherkin Welcome to Mastering QA! In this guide, we’ll introduce you to Cucumber and Gherkin, two powerful tools that revolutionize Behavior-Driven Development (BDD). Understanding these tools will provide a strong foundation for writing and automating your tests effectively.What is Cucumber?Cucumber is an open-source BDD framework that simplifies the process of defining and executing tests. It encourages collaboration between technical and non-technical team members, fostering better communication and understanding of software requirements.What is Gherkin?Gherkin is a human-readable language used to write Cucumber scenarios. It’s designed to be simple, easy to understand, and accessible to non-developers. Gherkin acts as the bridge between plain text descriptions of software behaviors and the automation code that validates those behaviors.Feature FilesFeature files are where Gherkin shines. These text files have a .feature extension and contain high-level descriptions of software features or functionalities. They serve as documentation and test scripts simultaneously.ScenariosScenarios are individual test cases written in Gherkin. They describe a specific behavior or test case, typically following a Given-When-Then structure. For example:Scenario: home-screen.featureFeature: Home Screen - Verify Web App Navigation Menu Links Scenario: Click the Login Icon Given the user is on the home screen When the user clicks the "login" icon Then the "Login" screen is displayed 1 Given 2 When 3 Then This keyword sets the stage for the scenario by describing the initial context or preconditions. It establishes the state of the system before the action occurs.This keyword defines the action or event that triggers the scenario. It represents the user's interaction with the system or the event that takes place.This keyword outlines the expected outcome or result after the action is performed. It specifies what should happen as a result of the interaction, allowing for validation of the scenario. Step DefinitionsStep definitions are the automation code that executes the steps in Gherkin scenarios.Step Defintionspublic class HomeStepDefs { public WebDriver driver = Hooks.driver; @Given("the user is on the home screen") public void the_user_is_on_the_home_screen() throws InterruptedException { // logic goes here } @When("the user clicks the {string} icon") public void the_user_clicks_the_icon(String iconName) { // logic goes here } @Then("the {string} screen is displayed") public void the_screen_is_displayed(String screenName) { // logic goes here } @When("the user clicks the {string} link") public void the_user_clicks_the_link(String linkName) { // logic goes here } }Benefits of Cucumber and Gherkin Improved Collaboration: Cucumber and Gherkin facilitate effective communication between technical and non-technical team members, leading to better software understanding. Reusable Steps: Gherkin steps can be reused across multiple scenarios, reducing redundancy and maintenance efforts. Living Documentation: Feature files serve as living documentation that stays up-to-date with your application's behavior. Automation: Cucumber allows you to automate tests based on Gherkin scenarios, making it easier to validate software functionality.ConclusionNow that you have a basic understanding of Cucumber and Gherkin, it’s time to Set Up Cucumber in Your Project. Setting Up Cucumber in Your Project In this guide, we’ll walk you through the essential steps to set up Cucumber in a Java project. Proper setup is crucial for ensuring a smooth workflow for your Behavior-Driven Development (BDD) testing. By following this guide, you’ll be well on your way!Prerequisites Java Development Kit (JDK) installed. Integrated Development Environment (IDE) Eclipse. Maven for dependency management.Create a New Maven ProjectTo embark on your journey with a Cucumber Gherkin project, the first step is to create a new Maven project. If you’re unfamiliar with setting up a Maven project, don’t worry. Our guide here on How To Create A New Maven Project in Eclipse, will walk you through the process step by step.Once your Maven project is successfully set up, the next crucial task is to add the core Maven dependencies required for your Cucumber Gherkin project. Head over to your pom.xml file and these between your dependencies tag. Adding Dependencies To pom.xmlpom.xml<!-- Selenium Java --> <dependency> <groupId>org.seleniumhq.selenium</groupId> <artifactId>selenium-java</artifactId> <version>4.20.0</version> </dependency> <!-- Cucumber Java --> <dependency> <groupId>io.cucumber</groupId> <artifactId>cucumber-java</artifactId> <version>7.11.0</version> </dependency> <!-- Cucumber JUnit --> <dependency> <groupId>io.cucumber</groupId> <artifactId>cucumber-junit</artifactId> <version>7.11.0</version> </dependency> <!-- JUnit 4 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> <!-- Extent Reports Cucumber Adapter --> <dependency> <groupId>tech.grasshopper</groupId> <artifactId>extentreports-cucumber7-adapter</artifactId> <version>1.14.0</version> </dependency> <!-- Extent Reports --> <dependency> <groupId>com.aventstack</groupId> <artifactId>extentreports</artifactId> <version>5.1.1</version> </dependency> <!-- Commons IO --> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.11.0</version> </dependency>Organizing Your Project Structure Now that we have our project created, let’s set up our base folders and directories. To get started, we’ll need to create a few specific folders. In this guide we’ll be incorporating the com.kicksapp package in our project to keep our files organize. Organizing Cucumber Project com/kicksapp/runners - This folder is where our test runner files will be stored. These files are essential for executing our test suites. com/kicksapp/stepdefs - Here, we'll keep our test step definitions. This organization helps in managing the steps involved in our tests, making them easy to locate and modify. src/test/resources/driver - This is the designated folder for our driver files. For this project, we'll be using Chromedriver. Ensuring the driver is in the right place helps in seamless test execution. src/test/resources/features - Most importantly, this folder will store our feature files. Feature files are the cornerstone of our behavior-driven development (BDD) approach, outlining the scenarios and behaviors our application should exhibit. Tip: Naming Your Package DirectoryYou can choose to keep you package as simple as src/test/java/runners or src/test/java/stepdefs. However in this guide We’ll be using the com/kicksapp/… package.Downloading the Cucumber Plugin for EclipseOnce we have these packages and folders set up, the next step is to download the Cucumber plugin for Eclipse. This plugin is essential for integrating Cucumber with Eclipse, providing a robust environment for running and managing our BDD tests.Navigate to the top menu and click on Help . From the dropdown menu, select Eclipse Marketplace… Installing Cucumber Plugin From The Eclipse Marketplace Search for Cucumber: In the Eclipse Marketplace window, use the search bar to type in [direction]"Cucumber"[/direction]. Press Enter to view the search results. Install the Cucumber Plugin: Locate the Cucumber plugin from the list of results. Click the [direction]Install[/direction] button next to the Cucumber plugin entry. Follow the prompts to complete the installation process. Restart Eclipse: Once the installation is finished, you will be prompted to restart Eclipse. Click [direction]Restart Now[/direction] to apply the changes.ConclusionOrganizing your project with these folders ensures a streamlined process where each component of your testing framework is easily accessible. This setup not only enhances productivity but also aligns with best practices in test automation, making it easier to scale and maintain your tests.Now you’re ready to Write Your First Gherkin Feature File. Continue to the next guide to dive into writing Gherkin scenarios. Writing Your First Gherkin Feature File Now that you have Cucumber set up in your project, it’s time to write your first Gherkin feature file. This guide will help you create a feature file and define scenarios using Gherkin syntax.Gherkin feature files are written with the .feature extension and contain a structured language with keywords like Feature, Scenario, Given, When, Then, And, and But. Let’s write a simple feature file for a checking the navigation on the Kicks Web App functionality. Kicks App | Flutter WebCreating a Feature FileFirst, navigate to your project’sfeaturesdirectory. This is where all your feature files will reside. To get started with our scenarios, we need to create a new file. Create a file named home-screen.feature inside the features directory. Creating The Home Screen Feature FilePath: home-screen.featuresrc/test/resources/features/home-screen.featureBy creating the home-screen.feature file, we establish a dedicated space for our home screen scenarios. This approach not only helps in organizing our tests but also makes it easier to locate and update them as needed.Write a Feature Scenario Ensuring a seamless user experience starts with verifying that all navigation links on the home screen function as expected. Below we are going test a few test cases related to the navigation menu.home-screen.feature# Author: J Richard | Mastering QA Feature: Home Screen - Verify Web App Navigation Menu Links Scenario: Click the Login Icon Given the user is on the home screen When the user clicks the "login" icon Then the "Login" screen is displayed Scenario: Click the Products link Given the user is on the home screen When the user clicks the "Products" link Then the "Products" screen is displayed Home Screen Feature File ScenariosUnderstanding Gherkin Syntax Feature: Provides a detailed overview of the feature being tested, outlining its purpose and functionality. Scenario: Specifies a particular test case for the feature, illustrating a unique situation to validate its performance. Given: Establishes the initial conditions and context necessary for the test to proceed, ensuring a proper setup. When: Captures the specific actions taken by the user during the test, detailing the interactions that trigger the functionality. Then: Articulates the expected results of the test, defining the criteria for success and the desired behavior of the feature. Given the user is on the home screenThis step sets the initial context. It assumes the user has already landed on the home screen of the web application. When the user clicks the "login" icon This action step simulates the user clicking on the login icon, which is expected to take them to the login screen. Then the "Login" screen is displayedThe final step verifies the outcome, ensuring that clicking the login icon indeed navigates the user to the login screen. Click the Products Link TestThe second scenario is pretty much similar but in this case we will be clicking the products link and verifying that we landed there successfully.ConclusionYou’ve written your first Gherkin feature file. Next, you’ll learn how about Scenario Outlines and Examples. Continue to the next guide to explore step definitions. Scenario Outlines and Examples In this guide, you’ll learn how to use scenario outlines and examples to write more dynamic and data-driven tests. This allows you to test multiple cases with different inputs and expected outcomes efficiently.What is a Scenario Outline? A Scenario Outline is a template for a scenario that can be run multiple times with different sets of data. It is useful when you want to test the same scenario with different inputs and expected outcomes. This helps in reducing redundancy and improving the readability and maintainability of your test suite.Syntax of Scenario OutlineThe syntax of a Scenario Outline in Gherkin is as follows:GherkinScenario Outline: Title of the scenario Given some precondition When some action is performed Then some expected outcome should happen Examples: | parameter1 | parameter2 | | value1 | value2 | | value3 | value4 | Scenario Outline: This keyword establishes a scenario template that allows for the reuse of the same test steps with varying data inputs, streamlining the testing process. Examples: This section specifies the various sets of data that will be used to fill in the placeholders defined in the Scenario Outline, enabling comprehensive testing of multiple scenarios efficiently.Using Examples in Scenario Outline The Examples section contains a table where each row represents a different set of values to be used in the scenario. The values from the table are substituted into the scenario outline, and the scenario is run once for each row. Cucumber Scenario Outline ExampleConsider a scenario where we want to test the products filter functionality of the Kicks website with different filters and verifying the item counts. This involves simulating user actions on the website to ensure that the filters for products work as expected.GherkinFeature: Products Page Filters & Stock Count Scenario Outline: User clicks product filter, choose a gender option and verify item count Given the user is on the products screen When the user clicks "<filter>" filter option And the user clicks the "<gender>" gender option And the user clicks a "<size>" shoe Then the first sneaker option is "<first_sneaker>" And the result is now "<item_count>" Examples: | filter | gender | size | first_sneaker | item_count | | Most popular | Male | 10.5 | Adidas Converse | 7 items | | Lowest price | Female | 6 | New Balance Streetwear | 13 items | | Highest price | Male | 9.5 | Jordan Orginal | 9 items | | Newest | Female | 7 | Nike Air Max 360 | 14 items |This feature focuses on verifying that the product filters on the Kicks website are working correctly. It includes tests for various filters such as Most popular, Lowest price, Highest price, and Newest to ensure they return the correct item count. Given the user is on the products screenThis step sets the initial condition that the user is on the products page of the website. When the user clicks "<filter>" filter optionThis action simulates the user clicking on a specific filter option, such as Most popular or Lowest price. And the user clicks the "<gender>" gender optionThis action simulates the user selecting a gender filter, such as Male or Female. And the user clicks a "<size>" shoeThis action simulates the user selecting a shoe size, such as 10.5 or 6. Then the first sneaker option is "<first_sneaker>"This step verifies that the first sneaker displayed matches the expected sneaker for the given filter. And the result is now "<item_count>"This step verifies that the total number of items displayed matches the expected item count.ConclusionGherkin Scenario Outlines are essential for enhancing clarity and efficiency in your behavior-driven development (BDD) process. They allow for reusable scenarios with varying inputs, simplifying test case creation and promoting collaboration among team members. In the next guide, you’ll learn about Implementing Step Definitions, where we’ll connect your Gherkin scenarios to executable code. Implementing Step Definitions Now is the time to create and implement our Step Definition Class in Cucumber. This critical step will ensure our test automation framework is robust and efficient. In this guide, we will walk you through the process of setting up your Step Definition Class, specifically focusing on creating a file to store your HomeStepDefs file within your project.Setting Up Your Step Definition ClassTo begin, navigate to the appropriate location in your project directory where you want to store your Step Definition files. It’s essential to keep your project well-organized, making it easier to maintain and scale as needed. In this case we’ll be storing our files in this location – src/test/java/com/kicksapp/stepDefs Cucumber Step Definitions Directory IDE: Launch Eclipse and open your project to get started on your Gherkin test definitions. Directory: Navigate to the src/test/java/com/kicksapp/stepDefs/ directory, where your step definitions will be organized. Create a New File: In the stepDefs directory, right-click and choose [direction]New File[/direction] to create a new file named HomeStepDefs.java, which will house your Gherkin step definitions for the Home feature.HomeStepDefssrc/test/java/kicksapp/stepDefs/HomeStepDefs.javaConvert Project to A Cucumber ProjectRight-click on your project and select Configure Convert to Cucumber Project . This set is necessary so we can generate our gherkin snippets. Converting Project To A Cucumber ProjectGenerate Gherkin Method SnippetsTo generate the necessary Gherkin method snippets, run the home-screen.feature file: Run Feature File: Right-click on the home-screen.feature file and select [direction] Run As > Cucumber Feature[/direction]. Review Snippets: Eclipse will execute the feature file, and if any step definitions are missing, it will generate method snippets for you. Copy these snippets into your HomeStepDefs.java class. Gherkin Generated Sample SnippetsGherkin Method Snippets@Given("the user is on the home screen") public void the_user_is_on_the_home_screen() { // Write code here that turns the phrase above into concrete actions throw new io.cucumber.java.PendingException(); } @When("the user clicks the {string} icon") public void the_user_clicks_the_icon(String string) { // Write code here that turns the phrase above into concrete actions throw new io.cucumber.java.PendingException(); } @Then("the {string} screen is displayed") public void the_screen_is_displayed(String string) { // Write code here that turns the phrase above into concrete actions throw new io.cucumber.java.PendingException(); } @When("the user clicks the {string} link") public void the_user_clicks_the_link(String string) { // Write code here that turns the phrase above into concrete actions throw new io.cucumber.java.PendingException(); }Now that we have our snippets, it’s time to add the necessary logic to each method to complete our HomeStepDefs class. This step is crucial as it bridges the gap between our feature files written in Gherkin and the actual automation code that interacts with our web application.In the HomeStepDefs class, we initialize a WebDriver instance through the Hooks class, ensuring a consistent browser session. The testUrl variable holds the URL of our web application, setting the stage for user interaction scenarios.HomeStepDefs – WebDriverpublic class HomeStepDefs { public WebDriver driver = Hooks.driver; private final String testUrl = "https://jahmalrichard.github.io/kicks-flutter-web-app/";Navigating to the Home ScreenThe first step is to navigate the user to the home screen. Using the @Given annotation, we define the method the_user_is_on_the_home_screen. This method directs the browser to the specified URL and pauses for 2 seconds to ensure the page is fully loaded. Kicks App | Home Screen@Given@Given("the user is on the home screen") public void the_user_is_on_the_home_screen() throws InterruptedException { driver.get(testUrl); Utils.wait(2); }Interacting with IconsNext, we manage user interactions with icons on the home screen. The @When annotation is used to define the method the_user_clicks_the_icon. This method receives an icon name as a parameter, locates the corresponding icon using a CSS selector, and performs a click action. Find & Click The Login Icon@When@When("the user clicks the {string} icon") public void the_user_clicks_the_icon(String iconName) { try { switch(iconName.toLowerCase()) { case "login": { WebElement loginIcon = driver.findElement( By.cssSelector("flt-semantics[aria-label=\"login-icon\"]")); loginIcon.click(); Utils.wait(2); break; } default: System.err.println("The icon called '" + iconName + "' was not found. Try again."); } } catch (Exception e) { e.printStackTrace(); } }Verifying Screen DisplaysAfter interacting with icons, it’s essential to verify that the correct screen is displayed. The @Then annotation defines the method the_screen_is_displayed, which checks for the presence of the Sign In button on the login screen to confirm successful navigation. Verify That The Sign In Button Exist Verifying That The Product Page Is Displayed@Then@Then("the {string} screen is displayed") public void the_screen_is_displayed(String screenName) { try { switch(screenName.toLowerCase()) { case "login": { WebElement loginSignInButton = driver.findElement(By.cssSelector("flt-semantics[aria-label=\"Sign In\"]")); assert loginSignInButton.isDisplayed(); Utils.wait(2); break; } case "products": { WebElement filterMostPopular = driver.findElement(By.cssSelector("flt-semantics[aria-label=\"Most popular\"]")); assert filterMostPopular.isDisplayed(); Utils.wait(2); break; } default: System.err.println("The screen named '" + screenName + "' was not found. Try again."); } } catch (Exception e) { e.printStackTrace(); } }Navigating via LinksLastly, we enable users to click on various links within the application. The @When annotation is used again to define the method the_user_clicks_the_link, which handles click actions for specified links. Tip: Navigating LinksThis method is related to the second scenario, where we click on the Products link and verify that we’re on he Products screen. User Clicks The Products Link@When@When("the user clicks the {string} link") public void the_user_clicks_the_link(String linkName) { try { switch(linkName.toLowerCase()) { case "products": { WebElement productsNavLink = driver.findElement( By.cssSelector("flt-semantics[aria-label=\"Products\"]")); productsNavLink.click(); Utils.wait(2); break; } default: System.err.println("The link named '" + linkName + "' was not found. Try again."); } } catch (Exception e) { e.printStackTrace(); } } } Tip: HomeStepDefsBy integrating these methods into our HomeStepDefs class, each method is crafted to handle specific interactions and verifications, making our tests both comprehensive and easy to understand.ConclusionNow that we have a solid grasp of creating and managing step definitions, it’s time to elevate our Cucumber skills further. In next guide, we’ll delve into Understanding Cucumber Tags, a powerful feature that can enhance the flexibility and efficiency of your testing framework. Understanding Cucumber Tags In this guide, you’ll learn how to use Cucumber tags and hooks to organize and manage your tests efficiently. Tags allow you to categorize your scenarios, and hooks provide a way to run code before or after scenarios.Tags in CucumberTags are a way to organize and control the execution of your tests. They allow you to group scenarios, features, or even specific steps, making it easier to manage large test suites. Tags are prefixed with @ and placed above the relevant Gherkin keyword. Single TagA single tag, such as @smoketest or @ignore, is used to label a specific test scenario. For instance, @smoketest indicates a basic test run to check the essential functionality, while @ignore is used to exclude certain tests from execution.Single Tag: @smoketest | @ignore@smoketest Scenario: Click the Login Icon Given the user is on the home screen When the user clicks the "login" icon Then the "Login" screen is displayed @ignore Scenario: Click the Products link Given the user is on the home screen When the user clicks the "Products" link Then the "Products" screen is displayedMultiple TagsMultiple tags, like @smoketest @critical, combine multiple categories, providing a more granular control over which tests to run. This combination might be used to run tests that are both part of the smoke test suite and critical for the application, ensuring that key functionalities are validated promptly.Multiple Tags: @smoketest @critical@smoketest @critical Scenario: Click the Login Icon Given the user is on the home screen When the user clicks the "login" icon Then the "Login" screen is displayedCreating a Test RunnerCreate a test runner class in the src/test/java/com/kicksapp/runners directory. We’re going to name this class HomeScreenRunner. Creating Home Screen Runner FileRunning Tests with TagsTo run tests with specific tags, use the @RunWithand @CucumberOptions annotations in your test runner class.The @CucumberOptions annotation is where you configure various aspects of your Cucumber tests. Here’s a breakdown of the options used in the snippet: Cucumber Runner File With OptionsHomeScreenRunner.classimport org.junit.runner.RunWith; import io.cucumber.junit.Cucumber; import io.cucumber.junit.CucumberOptions; @RunWith(Cucumber.class) @CucumberOptions( features = "src/test/resources/features/home-screen.feature", glue = "com.kicksapp.stepdefs", tags = "@smoketest", plugin = {"pretty", "html:target/cucumber-reports.html"}, monochrome = true ) public class HomeScreenRunner { }features = "src/test/resources/features/home-screen.feature": This specifies the path to the feature files. Feature files contain scenarios written in Gherkin language, which Cucumber executes.glue = "com.kicksapp.stepdefs": This option specifies the package where step definition methods are located. Step definitions are the actual code implementations of the steps described in the feature files.tags = "@smoketest": Tags are used to filter which tests to run. In this case, only the scenarios tagged with @smoketest will be executed.plugin = {"pretty", "html:target/cucumber-reports.html"}: This specifies the reporting plugins to use. The html plugin generates a simple html test report.monochrome = true: This option makes the console output more readable by removing unnecessary characters and colors.Tag ExpressionsCucumber supports tag expressions to combine multiple tags using logical operators: AND The AND operator in Cucumber tag expressions is used to run scenarios that are tagged with multiple tags simultaneously. For instance, consider the tags @login and @critical. By using the expression @login and @critical, Cucumber will execute only those scenarios that are tagged with both @login and @critical. This is particularly useful when you need to focus on tests that are both essential and pertain to specific functionalities.Tags: AND@CucumberOptions( features = "src/test/resources/features/home-screen.feature", glue = "com.kicksapp.stepdefs", tags = "@login and @critical", plugin = {"pretty", "html:target/cucumber-reports.html"}, monochrome = true ) OR The OR operator broadens the scope by running scenarios that match any of the specified tags. For example, using @moketest or @critical will run all scenarios tagged with either @smoketest or @critical. This approach is beneficial when you want to cover a broader range of tests without being too restrictive, ensuring that all relevant functionalities are tested.Tags: OR@CucumberOptions( features = "src/test/resources/features/home-screen.feature", glue = "com.kicksapp.stepdefs", tags = "@smoketest or @critcal", plugin = {"pretty", "html:target/cucumber-reports.html"}, monochrome = true ) NOT The NOT operator is employed to exclude specific tags from the test run. For example, the expression not @ignore will execute all scenarios except those tagged with @ignore. This is especially useful for excluding tests that are either known to fail, are under development, or are not currently relevant to the test cycle.Tags: NOT@CucumberOptions( features = "src/test/resources/features/home-screen.feature", glue = "com.kicksapp.stepdefs", tags = "@smoketest and not @ignore", plugin = {"pretty", "html:target/cucumber-reports.html"}, monochrome = true )ConclusionYou’ve mastered the art of using tags. Tags allow you to categorize your scenarios, making it easier to run specific tests based on your needs. Whether you’re focusing on a particular feature or running regression tests, tags streamline the process, saving you valuable time.Now that you are comfortable with tags, it’s time to start Understanding Cucumber Hooks. Understanding Cucumber Hooks In this guide, you’ll learn how to use Cucumber hooks to streamline your testing process and make your scenarios more efficient. Cucumber hooks are blocks of code that run at various points in the Cucumber test cycle, allowing you to set up and tear down the test environment, manipulate data, and configure test settings dynamically. By mastering hooks, you can enhance your test suite’s maintainability and readability, ensuring that your tests run smoothly and reliably.Hooks in CucumberHooks are special blocks of code that run at specific points in the test execution lifecycle. They allow you to set up preconditions and postconditions for your tests. In Cucumber, hooks are defined using the @Before and @After annotations.Types of HooksBefore HookThe @Before hook, as the name suggests, runs before each scenario. This means that any code you include in a @Before hook will execute before your test case starts. This is essential for preparing the test environment, ensuring that each test runs in a clean and consistent state. For instance, you might want to launch a browser, navigate to a specific URL, or initialize test data.@Before Hookpublic class Hooks { public static WebDriver driver; @Before public void setup() { System.setProperty("webdriver.chrome.driver", "src/test/resources/driver/chromedriver"); driver = new ChromeDriver(); driver.manage().timeouts().implicitlyWait(Duration.ofSeconds(10)); driver.manage().window().maximize(); }After HookAmong the different types of hooks, the @After hook plays a crucial role in ensuring your test scenarios are executed smoothly and efficiently. Specifically, the @After hook runs after each scenario, providing a perfect opportunity to perform cleanup tasks, release resources, or log information that helps in debugging and analysis.@After Hook@After public void tearDown() { if (driver != null) { driver.quit(); driver = null; }BeforeStepThe @BeforeStep hook, as its name suggests, runs before each individual step in your test scenarios. This hook can be particularly useful for setting up preconditions or performing repetitive tasks that need to be executed before every step.@BeforeStep Hook@BeforeStep public void beforeStep(Scenario scenario) { System.out.println("About to execute step: " + scenario.getName()); }AfterStepThe @AfterStep hook in Cucumber is designed to run a block of code after every single step of your test scenario. This capability is essential for tasks such as taking screenshots after each step to help with debugging or logging detailed information about the execution of each step. Implementing the @AfterStep hook can significantly enhance the visibility and traceability of your tests, making it easier to identify where an issue occurred if a test fails.@AfterStep Hook@AfterStep public void afterStep(Scenario scenario) { Utils.wait(3); final byte[] screenshot = ((TakesScreenshot) driver).getScreenshotAs(OutputType.BYTES); scenario.attach(screenshot, "image/png", "image"); }Conditional Hooks To further refine and control the execution of hooks, Cucumber provides the feature of conditional hooks with tags. Tags in Cucumber are metadata assigned to scenarios or feature files, and they can be used to conditionally apply hooks. For instance, if you have specific setup or teardown procedures that should only run for certain tests, you can tag those tests accordingly and define hooks that only trigger for those tags.Conditional Tagsimport io.cucumber.java.Before; import io.cucumber.java.After; public class Hooks { @Before("@login") public void beforeLogin() { // Code to run before scenarios tagged with @login } @After("@logout") public void afterLogout() { // Code to run after scenarios tagged with @logout } }ConclusionIncorporating hooks into your Cucumber tests is a powerful way to maintain a stable test environment, enhancing the overall reliability of your test suite. With hooks, you gain precise control over your test execution process, ensuring each scenario begins and ends in a consistent state. This mastery can lead to more trustworthy and efficient testing, ultimately contributing to higher quality software. Now that you are comfortable with tags and hooks, it’s time to start Running Your Cucumber Tests & Generating Reports. Running Cucumber Tests & Generating Reports Setting up Hooks and Tags in Cucumber is just the beginning of efficient test automation. Once your environment is configured, the next step is to explore the various methods available for executing your Cucumber scripts.Each method has its unique advantages and use cases. In this guide, we will delve into three primary ways to run your Cucumber tests: The Feature File - This method is ideal for quickly running specific features during development. JUnit Test - This method is suitable for developers looking to perform rapid testing of their scripts with minimal setup.

It is designed to make testing fast, easy, and reliable for developers and QA engineers. Cypress tests anything that runs in a browser, making it an essential tool for web application testing.What is Cypress?Cypress is an open-source testing framework that allows developers to write end-to-end tests, integration tests, and unit tests. Unlike other testing tools, Cypress is built on a new architecture and runs in the same run-loop as the application. This unique approach provides better, more reliable, and faster tests.Key Features of Cypress Time Travel: Cypress takes snapshots as your tests run. You can hover over each command in the Test Runner to see exactly what happened at each step. Debugging: Cypress provides readable error messages and stack traces. It also has the ability to debug directly from Chrome DevTools. Real-time Reloads: Cypress automatically reloads whenever you make changes to your tests. Automatic Waiting: Cypress waits for commands and assertions before moving on. There is no need to add explicit waits or sleeps. Spies, Stubs, and Clocks: Like any good testing framework, Cypress comes with built-in spies, stubs, and clocks.Time TravelCypress is a powerful tool for end-to-end testing, and one of its standout features is Time Travel. This feature allows testers to visually travel back in time through their tests, inspecting every single step, action, and response. By leveraging Cypress Time Travel, testers can debug applications more effectively, quickly identifying where and why tests fail. Cypress Time Travel From TestThe interactive nature of Time Travel means you can hover over commands in the Command Log and instantly see what happened at each point in time, making debugging a breeze. This visual timeline is invaluable for understanding the exact state of your application at any given moment during the test.Debugging with CypressDebugging in Cypress is straightforward and user-friendly. Unlike traditional testing frameworks, Cypress provides real-time feedback and detailed error messages directly in the browser. This means you don’t have to waste time switching between different tools or digging through complex logs. Cypress Debugging Error MessageWith Cypress, you can debug directly within the browser using powerful developer tools. Moreover, Cypress automatically captures screenshots and videos of failed tests, making it easier than ever to pinpoint issues. By using Cypress’s robust debugging capabilities, you can save time and effort, ensuring your tests are both reliable and maintainable.Real-time ReloadsOne of the most impressive features of Cypress is its real-time reloads. Whenever you make a change to your tests or application code, Cypress automatically reloads and reruns the tests. This continuous feedback loop means you can see the effects of your changes immediately, without the need to manually restart the test runner. Cypress Reload On ChangeReal-time reloads significantly speed up the development process, as they allow for instant validation of code changes. This feature is particularly useful for teams practicing Test-Driven Development (TDD) or Continuous Integration (CI), as it ensures that all code modifications are immediately tested and validated.Automatic WaitingCypress takes the headache out of dealing with timing issues in your tests with its Automatic Waiting feature. Traditional test frameworks often require you to add manual waits or timeouts to ensure elements are ready for interaction. However, Cypress automatically waits for elements to appear, animations to complete, and AJAX requests to finish before moving on to the next command. Cypress Automatic Waiting - Super Fast!This intelligent waiting behavior ensures your tests are more reliable and less flaky. With Cypress Automatic Waiting, you no longer need to worry about intermittent test failures caused by elements not being ready. This feature helps create robust tests that are more reflective of real user interactions.Spies, Stubs, and ClocksCypress provides powerful utilities for spying, stubbing, and controlling time, which are essential for comprehensive testing. With spies, you can monitor function calls and ensure your application behaves as expected. Stubs allow you to replace real functions with mock implementations, making it possible to test your application in isolation.This is particularly useful for simulating different responses and scenarios without relying on a live backend. Additionally, Cypress’s clocks feature lets you control and manipulate the passage of time in your tests, allowing you to test time-dependent code more effectively. These tools give you full control over your test environment, enabling you to simulate complex scenarios and ensure your application is rock-solid under any condition.ConclusionCypress is a game-changer for front-end testing.

Writing Your First Test in Cypress With Cypress installed and set up, it’s time to write your first test. This guide will walk you through creating a basic test to validate that Cypress is correctly configured and running. Writing tests in Cypress is intuitive and straightforward. Here’s an example of a basic test:Writing a Cypress TestHere’s an example test that checks if the login page loads correctly when the icon is clicked from the Home screen.Create a New Test FileCreate a new file in the cypress/e2e/home directory. In this example we’re going to create a new test file called home.cy.js. This file is going to house all of our scenarios related the Home page. home.cy.jsdescribe('Home Screen', () => { it('should navigate to the login page when the login icon is clicked', () => { const kicksAppsUrl = 'https://jahmalrichard.github.io/kicks-flutter-web-app/'; cy.viewport(1920, 1080); // Set the viewport to a standard desktop size cy.visit(kicksAppsUrl); // Load the web application cy.get('flt-semantics[aria-label="login-icon"]') .should('be.visible').click(); // Locate and click the login icon cy.get('flt-semantics[aria-label="Sign In"]') .should('exist'); // Verify navigation to the login page }); });In this example, the describe block is used to group tests related to the Home Screen. Inside the it block, we have a single test case that checks whether the application correctly navigates to the login page when the login icon is clicked. Test Setup: The first step in the test is setting up the viewport size to 1920x1080 pixels. This ensures the test runs in a simulated screen size that closely mirrors a typical desktop display. This is optional. Visiting the Application URL: The next step involves visiting the specific URL of the web application. This is done using cy.visit(kicksAppsUrl);, where kicksAppsUrl is a variable holding our application's URL. Interacting the Login Icon: Once the page is loaded, the test uses cy.get to locate the login icon on the page. This element is identified using a semantic label aria-label="login-icon" within the flt-semantics tag. The should('be.visible') command ensures that the icon is visible before attempting to click it. This step is critical as it validates that the icon is correctly displayed on the page before any action is performed. Asserting the URL Path: The test asserts that the URL now contains the /sign-in path using cy.url().should('include', '/sign-in'). This check ensures that the application navigates to the correct page after the icon is clicked. Verifying Navigation to the Login Page: After clicking the login icon, the test checks whether the application has navigated to the login page by looking for an element with the aria-label="Sign In". The should('exist') command is used here to confirm that this element is present in the DOM, which indicates successful navigation. Run Your TestOpen Cypress Test Runner if it’s not already openRun Testnpx cypress open Browsers Available To Run Test OnSelect your test file home.cy.js from the Test Runner to execute it. You should see your test running in the browser, with all assertions passing. Cypress Runner with Home Spec Cypress Run Home Test - PassedConclusionYou’ve written and executed your first Cypress test. This basic test demonstrates how to visit a page, interact with elements, and make assertions. In the next guide, we will delve into Setting Up A Reliable & Scalable Tests to better understand how to organize and manage your test suite effectively. Setting Up a Reliable and Scalable Test Suite In Cypress In this guide I’ll walk you through some essential Cypress features, such as setting the baseUrl, using the beforeEach hook, organizing tests with nested describe blocks, and creating custom commands. Let’s dive in!Using the baseUrl to Store Your Test URLOne of the first steps in setting up a Cypress project is configuring your test environment. Instead of hardcoding URLs throughout your tests, you can streamline your code by using the baseUrl configuration in Cypress. This not only makes your tests more maintainable but also easier to read and manage. Setting the baseUrl: To set up your baseUrl, navigate to your cypress.json file (located in the root of your Cypress project) and add the following configuration:cypress.config.jsconst { defineConfig } = require("cypress"); module.exports = defineConfig({ e2e: { defaultCommandTimeout: 10000, // 10 seconds pageLoadTimeout: 60000, // 60 seconds for page load baseUrl: 'https://jahmalrichard.github.io/kicks-flutter-web-app/', setupNodeEvents(on, config) { }, }, }); With this configuration, you can now visit your URL automatically during test.cy.visitcy.visit('/');Cypress automatically prepends the baseUrl to any relative URL you provide, making your tests more readable and easier to maintain. If you ever change your testing environment (e.g., from localhost to a staging server), you only need to update the baseUrl in one place.Using the beforeEach Hook in CypressThe beforeEach hook is a powerful feature in Cypress that allows you to run a specific piece of code before each test within a describe block. This is particularly useful for setting up a consistent test environment, ensuring that each test starts with the same conditions. Implementing beforeEach: In our sample script, we see the beforeEach hook used to set the viewport size and visit the homepage before each test. cy.viewport(1500, 780): Sets the browser window size to 1500x780 pixels, ensuring consistency across all tests. cy.visit('/'): Navigates to the homepage, using the relative path since baseUrl is set. cy.wait(5000):Pauses the test for 5 seconds to ensure that all elements on the page are loaded and ready for interaction.beforeEachdescribe('Home Screen', () => { beforeEach(() => { // This will run before each test, ensuring the website is always launched with custom viewport cy.viewport(1500, 780); cy.visit('/'); cy.wait(5000); // Ensures the page has fully loaded before running the test }); // Test cases will follow here... });This setup ensures that every test in the Home Screen block starts with the same conditions, leading to more reliable and predictable test outcomes.Using Nested describe BlocksAs your test suite grows, organizing your tests becomes crucial. Cypress allows you to structure your tests using nested describe blocks, which is particularly useful for grouping related tests and making your test suite easier to navigate.Implementing Nested describe Blocks:In the provided script, we see a nested describe structure used to organize tests related to the Home Screen and its Navigation Menu: Outer describe block (Home Screen): Groups all tests related to the home screen of your application. Nested describe block (Navigation Menu): Further organizes tests that specifically deal with the navigation menu.Nested describe()describe('Home Screen', () => { beforeEach(() => { cy.viewport(1500, 780); cy.visit('/'); cy.wait(5000); }); describe('Navigation Menu', () => { it('should navigate to the About Us page when the about link is clicked', () => { cy.get('flt-semantics[aria-label="About us"]') .should('be.visible') .focus() .click({ force: true }); cy.url().should('include', '/about-us'); const aboutUsPageHTitle = createMultilineSelector('About us'); cy.get(aboutUsPageHTitle).should('be.visible'); }); // Additional test cases for other navigation links... }); });This structure not only makes your tests easier to manage but also provides clear reporting when tests are run. You can easily identify which part of your application a failing test belongs to based on the describe block hierarchy.Using Custom Commands in CypressCypress allows you to extend its functionality by creating custom commands, which can simplify repetitive tasks and make your tests more expressive. Custom commands are particularly useful for abstracting complex interactions or frequently used selectors.Creating and Using a Custom Command:In the provided script, the createMultilineSelector command is imported and used to generate a selector for elements with multiline text. createMultilineSelector: This custom command likely returns a selector that matches elements based on their aria-label attribute, specifically targeting multiline text. By using this command, we avoid duplicating complex selectors throughout our tests. Usage in Tests:Instead of writing out the full selector each time, you simply call createMultilineSelector('About us'), making the test more readable and easier to maintain.Using createMultilineSelectorimport { createMultilineSelector } from '../../support/e2e.js'; describe('Home Screen', () => { beforeEach(() => { cy.viewport(1500, 780); cy.visit('/'); cy.wait(5000); }); describe('Navigation Menu', () => { it('should navigate to the About Us page when the about link is clicked', () => { cy.get('flt-semantics[aria-label="About us"]') .should('be.visible') .focus() .click({ force: true }); cy.url().should('include', '/about-us'); const aboutUsPageHTitle = createMultilineSelector('About us'); cy.get(aboutUsPageHTitle).should('be.visible'); }); // Additional test cases... }); });Creating Custom CommandsYou can define custom commands in the cypress/support/e2e.js file. Here’s how you might define the createMultilineSelector command:Custom function – createMultilineSelector()import './commands' export function createMultilineSelector(text) { let selector = 'flt-semantics[aria-label="'; for (let i = 0; i < text.length; i++) { selector += text[i]; if (i < text.length - 1) { selector += '\n'; // Add a newline after each character, except the last one } } selector += '"]'; return selector; }This function dynamically creates a selector that matches any element whose aria-label contains the specified text, making it versatile for various testing scenarios. ConclusionNow that we have our Cypress script set up in a scalable state, we’re ready to take the next step Running Test Scenarios in Cypress to ensure our application behaves as expected across different user interactions. This is where the true power of Cypress shines. By crafting various test scenarios, we can simulate real-world usage patterns, validating that all parts of our web application function correctly under different conditions. Running Test Scenarios in Cypress Before diving into the methods of running tests, let’s first expand our test suite with a few additional scenarios. These new tests will help us better understand the different ways Cypress can be utilized.Enhancing the Home Screen ScenariosIn this guide we’ll be going through the application, checking the links in the header menu like Products, Login, Cart. These are essential user flows, and ensuring they work correctly is vital for a seamless user experience. For instance, when the user clicks on the Products link, the application should navigate to the Products page, where the title Performance Sneakers should be visible. Similarly, clicking the login icon should direct the user to the sign-in page, with the Sign In button present and ready for interaction. The same applies to the Cart icon, leading the user to a Shopping Cart page, confirming the presence of the Shopping Cart title.Below is the enhanced version of the previous home screen test file, which includes test the new use cases mentioned above.Enhanced Home Screen Scenariosit('should navigate to the Products page when the products link is clicked', () => { cy.get('flt-semantics[aria-label="Products"]') .should('be.visible') .focus() .click({ force: true }); cy.url().should('include', '/products'); cy.wait(3000); const productsPageTitle = createMultilineSelector('Performance Sneakers'); cy.get(productsPageTitle).should('be.visible'); }); it('should navigate to the Login page when the login icon is clicked', () => { cy.get('flt-semantics[aria-label="login-icon"]') .should('be.visible') .focus() .click({ force: true }); cy.url().should('include', '/sign-in'); cy.get('flt-semantics[aria-label="Sign In"]').should('exist'); }); it('should navigate to the Cart page when the cart icon is clicked', () => { cy.get('flt-semantics[aria-label="cart-icon"]') .should('be.visible') .focus() .click({ force: true }); cy.url().should('include', '/cart'); const shoppingCartTitle = createMultilineSelector('Shopping Cart'); cy.get(shoppingCartTitle).should('be.visible'); });Running Test Using: Cypress RunNow that we’ve expanded our test suite, we can explore different ways to run these tests in Cypress. One approach is using the Cypress run command. This command allows you to run your tests in headless mode, meaning the tests execute without opening a browser window. This method is particularly useful for integrating tests into CI/CD pipelines where you need the tests to run automatically without manual intervention.cypress runnpx cypress run --spec cypress/e2e/home/home-advance.cy.js Cypress Testing Running In Headless ModeRunning Test Using: Cypress OpenAlternatively, you can use the npx cypress open command. This command opens the Cypress Test Runner in a graphical interface, allowing you to manually select and run tests. It’s an excellent way to visually interact with your tests and see them run in real-time, which can be particularly useful during the development phase when debugging issues.cypress opennpx cypress open Choosing E2E Testing To Start Cypress Test Browsers Available To Run Test On List of Cypress Tests To Choose From Cypress Test Runner With A Passed TestRunning Test Using: package.jsonFor convenience, you might want to add commands directly into your package.json file. This allows you to run specific test scripts or open the Cypress Test Runner with a single command.package.json"scripts": { "test": "echo \"Error: no test specified\" && exit 1", "all-e2e-gui": "npx cypress open --e2e", "home-test-headless": "npx cypress run --spec \"cypress/e2e/home/home-advance.cy.js\"" }, Viewing the package.json file. To view the Run Script | Debug Script options, hover your mouse over the script name and it will display. all-e2e-gui : npx cypress open --e2e - This gives you the ability to launch the Test Runner directly from the terminal. home-test-headless: npx cypress run --spec \"cypress/e2e/home/home-advance.cy.js\ - This is to run your home screen tests in headless mode, ensuring that you can quickly execute these tests without needing to manually input commands each time.ConclusionRunning test scenarios in Cypress is a seamless experience, thanks to its versatility in execution methods. By enhancing your test scenarios and leveraging different ways to execute them, you can ensure that your testing process is both efficient and effective. In the next guide you learn about Connecting Your Cypress Project To Cypress Cloud! Connecting Cypress Project to Cypress Cloud Connecting your Cypress project to Cypress Cloud is an essential step to enhance your testing workflow. Cypress Cloud offers robust features such as test recording, parallelization, and integration with CI/CD pipelines, which can significantly improve the efficiency and visibility of your test results. In this guide, we’ll walk through the steps to set up and connect your Cypress project to Cypress Cloud, ensuring a seamless integration. Cypress Cloud Login PageSetup Cypress Cloud AccountFirst, sign up for a Cypress Cloud account at Cypress Cloud. Once registered, create a new project in the Cypress Cloud dashboard. This project will be linked to your local Cypress project. Creating A New Project In Cypress CloudAdd Cypress Project ID To Your Local ProjectIn your local project, let’s add project id to the cypress.config.js file. You can find this file in the root of the project. Reviewing The Cypress Project Configcypress.config.jsconst { defineConfig } = require('cypress'); module.exports = defineConfig({ projectId: 'your-project-id', // other configurations }); Adding Project ID To Local ProjectChoose Your CI Provider – GitHub To start recording test runs in a pipeline we have to configure our CL Provider in this case, we’ll be configure the the GitHub Actions.

Running Cypress Run Record For Home Advance Test Setting the CYPRESS_RECORD_KEY In GitHubCreate Cypress.yml FileTo set up your Cypress project for seamless integration with CI/CD pipelines, the first step is to create a directory and a new cypress.yml file. This file will house all your pipeline configurations, ensuring your testing processes are streamlined and efficient. Navigate to your project directory, and within the Cypress local project, add a new directory at the following location: .github workflows . Creating Directory To Store The Cypress.yml FileIn the Cypress Cloud Setup Guide, you’ll start by copying the generated cypress.yml file that’s been tailored for your project. To better align this configuration with the specific needs of your project, I’ve made several adjustments to the file. Tweaked Cypress YML File In Staging Cypress YML File - New file created. Focus On Main Branch Only - Refined the on push step to trigger exclusively when changes are pushed to the main branch. Self Hosted - Using local workstation as the runner in GitHub. Single Container - Optimized resource usage by reducing the number of containers from two to one. Added Build & Start Scripts - Added two essential scripts: 'build' and 'start'. These scripts are designed to efficiently prepare and initialize the project environment. Environment Variable - Mod the environment variable naming convention by updating GH_TOKEN to replace the restricted GITHUB_TOKEN named variable. Configure Your Runner & Personal Access TokenBefore you commit your yaml file ensure that your that you have your Runner and PAT token are configured. Failure to do so will result in the test not running in the pipeline. GitHub Runner Is Idling Added GH TOKEN in GitHub in ActionView Cypress Record Results In The Cloud. Before finalizing the YAML file for our project, let’s take a moment to revisit your Cypress Cloud Account. Here, you should be able to see the previous test run that we initiated through the Terminal. This step is crucial as it ensures that the command we executed earlier has been correctly captured by Cypress Cloud. Viewing Cypress Run Record ResultsCommit Your Cypress YML File To effectively manage your YAML file execution within the pipeline and seamlessly integrate it with Cypress Cloud, you’ll first need to commit your changes. In my project, I utilize GitLens, a powerful tool for handling Git Pull and Push requests. Committing Cypress YML ChangesBegin by crafting a clear and concise commit message that reflects the changes made. Once your commit message is ready, push your changes directly to your branch. This process will trigger the pipeline, allowing you to observe the YAML file execution in real time. Cypress YML Starting The Pipeline JobMonitoring Cyress Cloud RunAfter setting up and ensuring that everything is functioning smoothly, it’s time to verify whether Cypress Cloud is actively monitoring and recording your tests. You the commit message and as well as a blue spinning icon that shows that the test is in action!

Cypress Test Results In GitHubWhen you click the View in Cypress Cloud link, you’ll be seamlessly redirected to the Cypress Cloud results, offering a comprehensive overview of your test outcomes. It’s a smooth transition that enhances your testing workflow. Based on the configuration in my package.json file, this script executed all the tests within the e2e folder, specifically targeting the home-basic.cy.js and home-advance.cy.js tests. This setup ensures that your end-to-end testing is thorough and that the results are conveniently accessible through Cypress Cloud, optimizing your testing process and improving overall efficiency. Run Test Results In Cypress CloudEnabling Video Recording & Screenshots To enable video capture in your Cypress test runs, you need to configure the appropriate settings in your cypress.config.js file. cypress.config.js (Enabling Video & Screenshots)const { defineConfig } = require("cypress"); module.exports = defineConfig({ projectId: "[your-id-here]", // Add your projectId here e2e: { defaultCommandTimeout: 10000, // 10 seconds pageLoadTimeout: 60000, // 60 seconds for page load baseUrl: 'https://jahmalrichard.github.io/kicks-flutter-web-app/', video: true, // This ensures video recording is enabled videoCompression: 32, // This compresses the video to save space screenshotOnRunFailure: true, // Automatically takes a screenshot when a test fails screenshotsFolder: 'cypress/screenshots', // Specifies where screenshots are saved in the project setupNodeEvents(on, config) { // Add any node event listeners here }, }, }); video - Begin by setting the video property to true, which activates video recording for all your test executions. videoCompression - To manage the size of the recorded videos, adjust the videoCompression setting to 32. This compression level strikes a balance between video quality and storage. screenshotOnRunFailure - This feature automatically captures a screenshot whenever a test fails, providing a visual snapshot of the problem at the exact moment it occurs. screenshotsFolder - By setting the screenshotsFolder to 'cypress/screenshots', you ensure that all screenshots are organized in a dedicated folder within your project.Cypress Passed Test With Video PlayBack Cypress Passed Test With Video PlaybackCypress Failed Test With Screenshot Cypress Failed Test With ScreenshotConclusionNow that your Cypress project is connected to Cypress Cloud, you’ll immediately experience the powerful features Cypress Cloud offers. These features include parallel testing, seamless CI/CD integration, and automatic screenshots and videos.In the upcoming guide, we’ll dive deeper into Using Advance Assertions In Cypress. Using Advanced Cypress Assertions In this advanced assertion guide, we delve into various Cypress commands and their functionalities, focusing on enhancing your testing strategy and ensuring your web application is robust and reliable. These commands, including .next(), .eq(), .include(), .within(), .and(), .then(), and others, provide nuanced control over test scenarios, making them indispensable for comprehensive testing.Understanding Cypress AssertionsThe .next() command in Cypress is used to select the next sibling DOM element within a parent element. This command is particularly useful when you need to perform assertions on elements that are dynamically generated or are sequentially placed in the DOM. For example, if you want to test the navigation menu items in a sequence, you can use .next() to move from one item to the next..next()cy.get('.menu-item') .first() .next() .should('have.text', 'About Us'); This snippet selects the first menu item and asserts that the next sibling has the text About Us, helping ensure the navigation menu is correctly ordered.The .eq() command is another powerful tool in Cypress, used to select an element at a specific index. This is extremely useful for assertions where elements are identical in structure but differ in content or position. For instance, if you’re testing a list of products, you can use .eq() to assert specific properties of each product. .eq()cy.get('.product-item') .eq(2).should('contain', 'Laptop'); In this assertion, Cypress selects the third product item (index:2) and checks if it contains the text Laptop which helps verify the correct rendering of products.The .include() assertion checks if a given string or element contains a specific substring or child element. This is essential for validating partial matches in text or the presence of specific elements within a container. For example, you might want to ensure that a promotional banner includes the keyword Discount. .include()cy.get('.banner') .should('include.text', 'Discount'); This code ensures that the banner element has the word Discount, confirming the presence of expected promotional content.Enhancing Test Coverage with .within() and .and()The .within() command allows you to scope your assertions to a specific portion of the DOM. This is particularly valuable when you have a complex structure with repeated classes or IDs, as it enables precise targeting of elements within a specified container. For example, if you want to validate form fields within a login form, .within() helps isolate the form and perform checks without interference from other elements..within()cy.get('.login-form').within(() => { cy.get('input[name="username"]').type('testuser'); cy.get('input[name="password"]').type('password123'); });In this example, Cypress limits the scope to the .login-form container, ensuring that only the form fields inside it are interacted with, enhancing test reliability.The .and() command chains multiple assertions together, allowing for concise and readable test scripts. When you want to verify multiple properties of an element, .and() provides a clean way to do so in a single command..and()cy.get('.notification') .should('be.visible') .and('contain', 'Success'); This snippet checks that a notification is visible and contains the word Success effectively combining two assertions in a streamlined manner.Leveraging .then() for Synchronous TestingCypress’s .then() command is crucial for handling asynchronous operations and chaining commands in a synchronous manner. This is especially useful when you need to perform complex operations that depend on the results of previous commands. For instance, if you want to fetch data from an API and then validate the response within the test, .then() allows you to manage this flow seamlessly..then()cy.request('GET', '/api/products').then((response) => { expect(response.status).to.eq(200); expect(response.body).to.have.length.greaterThan(0); }); In this example, Cypress sends a GET request to the /api/products endpoint and then uses .then() to assert that the response status is 200 and that the response body contains more than zero products, ensuring the API’s correctness.Building Reliable Tests with CypressCombining these advanced Cypress commands allows developers to create robust and reliable tests that cover a wide range of scenarios, from simple UI checks to complex user flows. Utilizing .next(), .eq(), .include(), .within(), .and(), and .then() helps ensure your application behaves as expected under various conditions, enhancing test coverage and confidence in the application’s stability.ConclusionMastering these commands enables testers to write thorough, maintainable, and efficient Cypress tests for various applications, from single-page to e-commerce platforms. These assertions offer the flexibility to simulate real-world user interactions, ensuring higher-quality web applications and an improved user experience. In the next guide, we will explore Writing API Tests in Cypress. Writing API Tests in Cypress API testing is a critical component of modern software development, ensuring that your application’s back-end services are robust, reliable, and performant. Cypress, a popular end-to-end testing framework, is not only capable of testing the UI but also excels at API testing. In this guide, we’ll explore how to write API tests in Cypress, dive into some practical examples, and discuss the differences between cy.request and cy.api, two powerful commands for API testing in Cypress.cy.requestCypress provides a seamless way to perform API testing by leveraging its cy.request command. This command is ideal for making HTTP requests to your application’s backend or any third-party services it interacts with. Using cy.request, you can validate the response status, headers, body, and even the timing of API calls, making it an essential tool for API testing in Cypress. For instance, if you’re testing a REST API, you can easily send GET, POST, PUT, or DELETE requests and assert that the server’s responses are as expected.Let’s consider an example where we want to test a simple GET request to retrieve a list of users from an API endpoint. Using cy.request, the test might look something like this:cy.request()describe('API Testing with Cypress', () => { it('should fetch a list of users', () => { cy.request('GET', 'https://jsonplaceholder.typicode.com/users').then((response) => { expect(response.status).to.eq(200); expect(response.body).to.have.length(10); expect(response.body[0]).to.have.property('name'); }); }); });In this example, cy.request sends a GET request to the specified URL. The .then() method is used to handle the response, allowing us to assert that the status code is 200 and that the response body contains an array of users with the expected length and structure. This simple yet powerful approach highlights how Cypress makes API testing straightforward and accessible.cy.apiWhile cy.request is a fantastic tool for making HTTP requests, Cypress also offers the cy.api command through its official plugin, @cypress/plugin-api. This plugin provides a more feature-rich alternative to cy.request and is particularly useful for more complex API testing scenarios. One of the key differences between cy.request and cy.api is that cy.api automatically records requests and responses in the Cypress command log, making debugging and test reviews more intuitive.Consider a scenario where you need to perform a POST request to create a new user and validate the response. Using cy.api, you can write the following test:cy.api()describe('Advanced API Testing with Cypress', () => { it('should create a new user', () => { cy.api({ method: 'POST', url: 'https://jsonplaceholder.typicode.com/users', body: { name: 'John Doe', email: 'john.doe@example.com', phone: '1-770-736-8031 x56442', }, }).then((response) => { expect(response.status).to.eq(201); expect(response.body).to.have.property('name', 'John Doe'); }); }); });In this example, cy.api is used to send a POST request with a JSON payload to create a new user. The test then checks that the server returns a status code of 201 (indicating successful creation) and that the response body contains the correct data. The enhanced logging capabilities of cy.api provide valuable insights into the request and response, making it easier to diagnose any issues that arise during testing.ConclusionCypress is a versatile framework that not only excels at end-to-end testing but also provides robust tools for API testing. Whether you choose to use cy.request for its simplicity and flexibility or cy.api for its enhanced logging and feature set, Cypress makes it easy to implement and maintain high-quality API tests. By incorporating API testing into your Cypress test suite, you can ensure that both your front-end and back-end components work harmoniously together, leading to a more reliable and resilient application.
Automating UI Tests on Android Emulators Building on our knowledge of ADB, this guide focuses on automating UI tests on Android emulators. Automated UI tests ensure that your application’s user interface behaves as expected across different scenarios and devices.Why Automate UI Tests?Automated UI tests save time and resources by running tests that simulate user interactions. They help identify bugs and inconsistencies in the UI, providing a reliable way to maintain high-quality applications.Setting Up Espresso for UI TestingAdd DependenciesYou need to add Espresso and other related dependencies in your build.gradle file of your Android app module (app/build.gradle).android/app/build.gradle defaultConfig { testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner" }Create a Test Class In src/androidTest/java and call it MainActivityTest.This test will ensure that the app is launched and ready for interaction. The test method will simulate a user clicking the plus button and verifies the resulting UI state.MainActivityTest.class@RunWith(AndroidJUnit4.class) @LargeTest public class MainActivityTest {@RunWith(AndroidJUnit4.class): This annotation tells JUnit to run the test class using the AndroidJUnit4 test runner. This runner provides compatibility with Android components and manages the test lifecycle.@LargeTest: This annotation classifies the test as a “large” test. Large tests typically involve integration testing, where multiple components of the application are tested together.MainActivity.class@Rule public ActivityScenarioRule<MainActivity> activityRule = new ActivityScenarioRule<>(MainActivity.class); @Rule public DisableAnimationsRule disableAnimationsRule = new DisableAnimationsRule();@Rule: Rules in JUnit are used to add or extend the behavior of each test method in a test class. They provide additional functionality before and after each test is run.ActivityScenarioRule<MainActivity> activityRule: This rule launches the specified activity (MainActivity in this case) before each test and closes it after each test. It provides a simplified way to test activities. The ActivityScenarioRule starts and stops the activity and also ensures that the activity is running before the test begins.DisableAnimationsRule disableAnimationsRule: This custom rule is used to disable system animations during the test run. Animations can interfere with Espresso tests by causing unexpected delays or timing issues, so disabling them ensures more consistent test results.MainActivity.class@Test public void testClickPlusButton() throws InterruptedException { // Click the plus button to open the AddEditTaskActivity onView(withId(R.id.fab)).perform(click()); // Verify that the AddEditTaskActivity is displayed by checking for the presence of the title EditText onView(withId(R.id.titleEditText)).check(matches(withText(""))); }@Test: This annotation indicates that the following method is a test method. JUnit will execute this method as a test case.public void testClickPlusButton(): This is the test method. The method name typically describes what is being tested. In this case, it tests the behavior of clicking the plus button.onView(withId(R.id.fab)).perform(click());: This line uses Espresso to interact with the UI. It finds a view with the ID fab which is the floating action button in this app and performs a click action on it. Espresso’s onView method is used to find views in the current activity’s layout, and perform is used to execute actions on those views.onView(withId(R.id.titleEditText)).check(matches(withText("")));: This line verifies that a view with the ID titleEditText is displayed and that its text is empty. This check is used to confirm that the AddEditTaskActivity is displayed by looking for the presence of an empty title EditText. The check method is used to perform assertions on views, and matches verifies that the view’s state matches the specified condition. Since this is a ToDo app, let’s enhance the test suite by adding two more critical scenarios: one for adding a task and another for deleting a task.

For instance, to add JUnit for testing, include:pom.xml<dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.13.2</version> <scope>test</scope> </dependency>Dependency Management: Maven automates dependency updates, ensuring that all dependencies are compatible. Additionally, it manages transitive dependencies, automatically including libraries that your main dependencies rely on.ConclusionEfficiently managing external libraries and dependencies in Eclipse is essential for quality testers and developers. Whether you use the manual approach for static libraries or leverage tools like Maven and Gradle for dynamic dependencies, effective dependency management ensures seamless project workflows, improved testing accuracy, and minimized errors. In the next guide, you’ll learn about Best Practices for Refactoring Test Code, which will help you enhance the structure, readability, and maintainability of your test scripts, making them more resilient and easier to manage. Best Practices for Refactoring Test Code Best Practices for Refactoring Test Code are essential to maintaining test reliability and making automated testing more efficient and manageable. In the fast-paced world of quality assurance (QA), test code can quickly become complex and challenging to maintain, especially in extensive systems. Test refactoring is a systematic approach to improving the code’s structure without changing its behavior, enhancing readability, maintainability, and overall performance. This guide will walk you through effective techniques and best practices for refactoring test code in Eclipse IDE, a popular development environment used by quality testers.Why Refactor Test Code in Eclipse?Refactoring test code not only simplifies future updates but also reduces the chances of introducing bugs or inconsistencies in your automated tests. By using Eclipse IDE, a comprehensive platform for Java development, you can leverage tools and shortcuts to enhance the refactoring process. Eclipse’s built-in support for automated refactoring, code organization, and error-checking makes it an excellent choice for handling large test suites. Proper refactoring ensures tests are reliable, efficient, and sustainable as your project scales.Identify Problematic Test CodeStart by reviewing your test code for issues that may hinder maintainability or clarity. Tests that are difficult to understand, redundant, or prone to failure often signal the need for refactoring. Use Eclipse’s Code Smells feature to identify areas for improvement, such as duplicated code, overly complex methods, or excessive dependencies. Prioritizing areas that impact test readability or lead to frequent failures will yield the most benefit from refactoring.Keep Tests Small and FocusedOne of the primary goals in refactoring is to ensure each test has a single responsibility. Tests that cover multiple scenarios or actions are not only harder to debug but can also mask issues that may only occur in specific conditions. Refactoring large tests into smaller, focused tests improves readability and maintainability. In Eclipse, you can easily extract methods or classes, allowing for the separation of test responsibilities and making each test easier to manage.Use Descriptive Naming ConventionsDescriptive and consistent naming conventions make your test code self-explanatory, reducing the need for excessive comments or documentation. Rename variables, methods, and classes to reflect their purpose accurately, ensuring that anyone reading the test code understands its functionality without additional context. In Eclipse, the Rename (Shift+Alt+R) refactoring tool allows you to rename elements safely across your codebase, updating references automatically.Best Practices for Refactoring Test Code in EclipseUtilize Parameterized TestsRepeating the same logic across multiple tests with slight variations can lead to redundant code and maintenance issues. Parameterized tests allow you to pass different sets of data to a single test method, reducing code duplication. This approach is particularly effective in unit testing frameworks like JUnit, integrated into Eclipse. Use the JUnit Parameterized class or JUnit 5’s @ParameterizedTest to refactor repetitive tests, creating a cleaner and more maintainable suite.Organize Tests by FunctionalityOrganizing your test cases by functionality, such as creating folders or packages for specific modules, components, or screens, provides a clear structure to your tests. This structure enhances readability and makes it easier to locate specific tests. In Eclipse, you can create custom packages and use annotations to categorize tests, making it easier to navigate large test suites.Refactor Assertions for ClarityAssertions are critical in determining if tests pass or fail, so it’s essential to keep them simple and descriptive. Avoid complex assertion logic that can obscure the intent of the test. Using custom assertion methods can add clarity, especially in complex test scenarios. Eclipse supports a range of assertion libraries, such as AssertJ and Hamcrest, which provide fluent assertion syntax and enhance readability.Leverage Code Coverage ToolsCode coverage tools, like EclEmma for Eclipse, help you identify untested code sections, offering insights into areas that may require additional tests. High coverage does not guarantee perfect tests but helps ensure that your code is well-tested and reliable. Use coverage reports to guide your refactoring efforts and ensure critical paths are tested comprehensively.ConclusionRefactoring test code is a vital practice for maintaining high-quality, reliable test suites. By following these best practices in Eclipse, quality testers can improve code readability, reduce redundancy, and enhance test efficiency. From using parameterized tests and helper methods to adopting mocking and organizing tests by functionality, Eclipse offers numerous tools to simplify and streamline the refactoring process. Embrace these strategies to keep your test code clean, maintainable, and adaptable to future project requirements. Remember, consistent refactoring is the key to sustainable test automation that scales effectively with your application.

Flutter’s core features include a rich set of pre-designed widgets, a hot reload functionality for rapid development, and native performance, making it one of the most powerful frameworks for cross-platform development.Key Features of Flutter Widgets and Customizability One of the defining characteristics of Flutter is its reliance on widgets. Widgets are the building blocks of a Flutter application, and everything in Flutter—from buttons to text—is a widget. This approach allows for complete customizability of your application’s look and feel. Flutter provides a vast library of widgets that mimic the behavior of native components on both Android and iOS, allowing developers to create a consistent and platform-specific UI. Hot Reload for Rapid Development Flutter’s hot reload feature is a standout benefit for both developers and testers. Hot reload allows developers to see the results of code changes instantly, without needing to restart the entire application. This is a significant advantage during testing and debugging because it enables quicker iteration cycles, reducing the time spent on compiling and running changes. Single Codebase for Multiple Platforms With Flutter, developers can create applications for Android, iOS, web, and even desktop using a single codebase. This feature drastically reduces the development time and effort compared to writing separate codebases for different platforms. For QA testers, this means fewer discrepancies between platform versions, ensuring a more consistent user experience across devices.Types of Flutter TestFlutter offers a range of testing tools and frameworks that make life easier for testers. Whether you’re working on unit tests, widget tests, or integration tests, Flutter’s tools are designed to streamline the process and enhance your testing experience. Unit Testing: QA testers can write unit tests in Flutter to verify the functionality of individual components. This ensures that each piece of the application works as expected. Widget Testing: Widget testing is a powerful way to ensure that a particular UI component behaves correctly. QA testers can create widget tests to interact with and verify individual UI elements, such as buttons, forms, or animations. Integration Testing: Integration tests allow QA testers to verify the app’s performance as a whole by testing how various modules work together. In Flutter, integration tests are crucial for validating the entire flow of the application and ensuring that different features interact correctly.Benefits of Using Flutter for Mobile Development Cross-Platform Consistency Using Flutter ensures that the user experience remains consistent across all platforms. Since a single codebase is used, there are fewer variations between different versions of the app, making it easier for developers and testers to work in tandem and reduce discrepancies. Native Performance Flutter compiles directly to native ARM code, which ensures that the applications built with it offer excellent performance similar to native apps. Both developers and QA testers benefit from this, as testing on real devices reflects how the app will perform once released. Open-Source Community and Plugins Flutter has a growing open-source community, providing numerous plugins and third-party libraries to help speed up the development process. This resource pool is advantageous for QA testers, as there are many community-driven tools and integrations that facilitate testing automation, debugging, and more.ConclusionThis Introduction to Flutter highlights how Flutter is not only an effective tool for cross-platform development but also offers immense benefits for QA testers by streamlining the testing process. Flutter’s hot reload, powerful widgets, and single codebase allow developers and testers to work together more efficiently, ensuring faster releases and higher-quality products. To take your Flutter expertise to the next level, explore our guide on Setting Up a Testing Environment in Flutter and learn how to create a solid foundation for your testing workflows. Setting Up a Testing Environment in Flutter Setting up a testing environment in Flutter is a critical step for ensuring that your applications are bug-free, maintainable, and efficient. Flutter, with its growing popularity as a framework for cross-platform mobile development, makes testing relatively straightforward but requires a well-configured environment for comprehensive testing. This guide will walk you through the process of setting up a testing environment in Flutter, catering specifically to the needs of QA testers and developers. Setting Up FlutterSetting Up Your Flutter Development EnvironmentBefore diving into testing, ensure that your Flutter development environment is correctly configured. Install Flutter SDK by following the instructions on the official Flutter website. This installation will include essential tools such as flutter doctor, which helps diagnose configuration issues. Install Dependencies Run Flutter Doctor Install Dependencies: Make sure you have Dart SDK, an integrated development environment like VS Code and mobile simulators/emulators set up for testing on different devices.Run flutter doctor: Execute flutter doctor in your terminal to verify that your setup is complete, and to ensure you have all the required dependencies installed.Understanding Different Types of Flutter TestsTo effectively set up a testing environment in Flutter, you need to understand the three types of testing in Flutter: Unit Tests: Unit tests verify individual units of code, like functions or methods. They are useful for testing business logic in isolation. Widget Tests: Widget tests validate the behavior of a single widget. They run faster than integration tests and help in ensuring that individual parts of the UI work as expected. Integration Tests: Integration tests evaluate how different widgets work together in an application. These tests help simulate real user interactions to identify any issues.Flutter provides built-in testing libraries such as flutter_test, which offers tools for all three types of tests.Configuring the Testing Environment in FlutterAdding Testing DependenciesThe first step in configuring the testing environment in Flutter is to add the necessary dependencies to your project. Open the pubspec.yaml file and add the following dependencies:pubsepec.yml dev_dependencies: flutter_test: sdk: flutter mockito: ^5.0.0 integration_test: sdk: flutter Flutter Pubspec Setup flutter_test: This is the primary library for unit and widget testing in Flutter. integration_test: This package facilitates integration testing by allowing you to automate user flows.Setting Up Test Files In your project structure, create a folder named test/ to store your test files. Keep your test files organized based on the features or functionalities being tested. For instance: test/unit/ for unit tests. test/widget/ for widget tests. integration_test/ for integration tests.This folder structure will make it easier to maintain and navigate your tests as the application scales.Writing a Simple Unit TestUnit testing in Flutter starts by creating a new .dart file under test/unit/. Here is an example of a simple unit test:Sample Unit Testimport 'package:flutter_test/flutter_test.dart'; import 'package:your_app/math_utils.dart'; void main() { test('Adding two numbers should return correct sum', () { final result = addNumbers(2, 3); expect(result, 5); }); }In this example, addNumbers() is a method from math_utils.dart that you want to test. The test() function helps define the test scenario, and the expect() function is used to validate the result.Running TestsTo run your tests, use the following command in the terminal:bashflutter testThis command will run all the unit and widget tests in your test/ directory.ConclusionSetting up a testing environment in Flutter is an essential task for both QA testers and developers aiming for high-quality, reliable applications. A well-configured environment includes proper setup of the Flutter SDK, addition of essential testing dependencies, organized test files, and the ability to run unit, widget, and integration tests.To dive deeper into Flutter testing, explore the next guide, Writing and Running Unit Tests in Flutter, where you’ll learn how to write effective unit tests and execute them seamlessly. Writing and Running Unit Tests in Flutter Writing and running unit tests in Flutter is a crucial part of the development process that ensures the stability and reliability of your codebase. In this guide, we’ll cover the essentials of writing and running unit tests in Flutter, enabling you to improve code coverage and boost application stability.Introduction to Unit Testing in FlutterUnit testing is a software testing technique where individual units or components of an application are tested in isolation. In Flutter, a unit test validates a specific part of your logic, typically a function, method, or class, to ensure that it performs as expected. By writing and running unit tests in Flutter, you can catch bugs early, improve the overall reliability of your app, and ensure that each unit behaves predictably even as the code evolves. Flutter provides a simple yet powerful testing environment that includes tools like flutter_test and integration with popular third-party packages. Before diving into writing and running unit tests in Flutter, it’s important to understand the fundamental principles and tools used to create effective unit tests.Setting Up Unit Tests in FlutterTo get started with unit testing in Flutter, you need to set up the appropriate dependencies in your project. Flutter includes a package called flutter_test by default, which provides various functions and utilities that make writing tests easier. You can find it in your pubspec.yaml file:pubspec.yaml dev_dependencies: flutter_test: sdk: flutterWriting Unit Tests in FlutterWhen writing unit tests in Flutter, it is essential to focus on testing individual units of logic in isolation. Unit tests should be short, simple, and easy to maintain. Follow these steps to write a unit test in Flutter:Create a Test FileTest files should be placed in the test/ directory, which Flutter automatically generates when you create a new project. To create a test file, add a new .dart file under the test/unit directory. In this example we will call the file sign_in_screen_unit_test.dart. Flutter Unit TestInspect the Sign Up Screen ControllersWe will focus on examining the functionality of the sign-in screen in our project by exploring the sign_in_screen controller. This controller plays a pivotal role in handling user interactions with the sign-in screen. Specifically, it is responsible for capturing and processing the input data entered in the username and password fields. SigninScreen ControllerThe SignInController controller serves as the bridge between the UI and the business logic, ensuring that the text entered by the user is properly validated and prepared for authentication.Write Your Test CasesWhen writing test cases for the sign-in screen controller, focus on covering all key functionalities and edge cases. Test for valid and invalid inputs, such as correct and incorrect username-password combinations, empty fields, and valid formats.Here’s the code for the SignInController tests:Unit Test Exampleimport 'package:flutter_test/flutter_test.dart'; import 'package:get/get.dart'; import 'package:richapp/controller/sign_in_controller.dart'; void main() { group('SignInController Tests', () { late SignInController controller; setUp(() { controller = Get.put(SignInController()); }); tearDown(() { Get.delete<SignInController>(); }); test('should initialize with empty text controllers', () { expect(controller.emailOrUserNameController.text, isEmpty); expect(controller.passwordController.text, isEmpty); expect(controller.emailController.text, isEmpty); }); test('should update emailOrUserNameController text correctly', () { controller.emailOrUserNameController.text = 'testuser'; expect(controller.emailOrUserNameController.text, 'testuser'); }); }); } Understanding the Tests Test Initialization (setUp and tearDown) Each test is set up with a fresh instance of SignInController using Get.put, ensuring no shared state between tests. After each test, tearDown ensures the controller is removed using Get.delete. Testing Default Values The first test checks whether the emailOrUserNameController, passwordController, and emailController are initialized with empty text. This ensures the controller starts in a clean state. Testing Text Update The second test verifies that the text in emailOrUserNameController updates as expected when modified. This is a simple check for setter functionality.Running Unit Tests in FlutterOnce you have written your unit tests, it’s time to run them to ensure your code works as expected. You can run unit tests in Flutter using the following command:Run Flutter Unit Test# Runs all the tests flutter test # Run tests on in the unit directory flutter test/unit/ This command runs all the test files located in the test/ directory, including any subdirectories such as test/unit/, and displays the results in the terminal. If you wish to target a specific directory or test file, you can do so by providing the relative file path as an argument: Run Flutter Test vis Pathflutter test test/unit/sign_in_screen_widget_test.dartFlutter will execute the test cases and report the results, including any errors or failed tests. It is good practice to frequently run tests during development to catch issues early. Flutter Unit Test ResultsBest Practices for Writing and Running Unit Tests in FlutterTo ensure that your unit tests are effective and easy to maintain, consider the following best practices: Keep Tests Simple and Focused: Each test should focus on one specific behavior. This makes it easier to identify the root cause of any failure. Use Meaningful Test Names: Clearly describe what the test is validating so that anyone reading the test results understands the purpose of the test. Run Tests Frequently: The sooner you catch a bug, the easier it is to fix. Run tests frequently to catch issues as soon as possible. Ensure Code Coverage: Aim for high test coverage, but remember that quality is more important than quantity. Cover critical logic and edge cases, but avoid writing redundant tests.ConclusionWriting and running unit tests in Flutter is a fundamental practice for ensuring the reliability and stability of your application. This unit test demonstrates how to ensure your SignInController behaves as expected in terms of initialization, state updates, and resource management. Writing clear, focused tests like these can help catch bugs early and maintain a robust codebase.To explore the next step in Flutter testing, check out our guide on Widget Testing in Flutter, where you’ll learn how to test individual widgets effectively to enhance your application’s quality. Widget Testing in Flutter Widget Testing in Flutter is an essential part of the development and QA process, ensuring that individual components of a Flutter app function as expected. Unlike unit tests that focus on the smallest pieces of logic or integration tests that test larger portions of the app, widget testing focuses specifically on validating the behavior of UI components. By effectively employing widget tests, you can validate that widgets render correctly, handle user interactions as expected, and ensure UI changes propagate correctly. This guide aims to provide QA testers and developers with a clear understanding of widget testing in Flutter and practical steps to implement it effectively.What Is Flutter Widget Testing?Widget testing is all about ensuring that individual widgets in your Flutter application behave as expected. Unlike unit tests that focus on logic and computations, widget tests verify the UI and its interactions. For our Sign-In screen, we’ll simulate user actions and validate the UI’s response to these interactions. Running All Widget Tests in VSCodeSetting Up the Test EnvironmentBefore writing widget tests, you need to set up a robust test environment. In this project, I’ve used flutter_test for writing tests, along with ScreenUtil for responsive layouts and GetX for state management and navigation. Here’s how we prepare the environment to ensure smooth testing workflows.To get started with widget testing, follow these steps: Creating Widget Test File Create a New Test File: Navigate to the test/unit directory in your Flutter project and create a new Dart file. Since we're testing the sign in screen, let's name itsign_in_widget_test.dart. Add a Main Function: Inside the newly created file, add the main function to act as the entry point for your test. It should look like this: void main {}. Set Up the Test Environment: Add any dependencies or utilities you need for testing within the main function. For example, if you are testing a widget with routes or dependencies, ensure those are set up properly. Add a Teardown Function: After each test, it’s essential to reset the state to avoid conflicts between tests. Use the tearDown function for this purpose tearDown(() { Get.reset(); }); Below is a snippet I used to handle building the widget page and managing routes using GetX.Function: buildTestWidgetWidget buildTestWidget(Widget widget) { return ScreenUtilInit( designSize: const Size(430, 932), builder: (_, __) => GetMaterialApp( home: widget, initialRoute: '/', getPages: [ GetPage(name: '/', page: () => SignInScreen()), GetPage(name: '/signUpScreen', page: () => SignUpScreen()), GetPage(name: '/bottomNavigationScreen', page: () => HomeScreen()), ], ), ); }Writing Tests for the Sign-In ScreenVerifying Text Fields and ButtonsThe first step is to ensure that all key widgets are present on the screen. These include the email and password fields, as well as the Sign-In button. Verify email, password, and sign-in button keysWidget Test: Verify email, password, and sign-in button keystestWidgets('Verify email, password, and sign-in button keys', (WidgetTester tester) async { await tester.pumpWidget(createTestScreenWidget(SignInScreen())); await tester.pumpAndSettle(); // Verify widgets by key expect(find.byKey(Key('email_username')), findsOneWidget); expect(find.byKey(Key('password')), findsOneWidget); expect(find.byKey(Key('sign_in_btn')), findsOneWidget); });This test validates that the text fields and button are part of the widget tree, using their unique keys for identification.Testing Button Clicks and NavigationButtons are the core of user interactions. Let’s ensure the Sign-In button is clickable and navigates to the correct screen. Tapping Sign In Button Sign In Button Routing On the Home ScreenWidget Test: Sign In button is clickabletestWidgets('Sign In button is clickable', (WidgetTester tester) async { await tester.pumpWidget(createTestScreenWidget(SignInScreen())); await tester.pumpAndSettle(); // Find the button and tap it final primaryButtonFinder = find.byKey(Key('sign_in_btn')); await tester.tap(primaryButtonFinder); await tester.pumpAndSettle(); // Verify navigation expect(find.byType(HomeScreen), findsOneWidget); });This test not only verifies the button’s presence but also confirms successful navigation to the Home screen.Testing LinksLinks like Forgot Password or Sign Up are equally important. Here’s how to test that the Forgot Password link opens the appropriate modal: Widget Testing LinksWidget Test: Forgot Password link is clickabletestWidgets('Forgot Password link is clickable', (WidgetTester tester) async { await tester.pumpWidget(createTestScreenWidget(SignInScreen())); await tester.pumpAndSettle(); final forgotPasswordFinder = find.byKey(Key('forgot_password_link')); await tester.tap(forgotPasswordFinder); await tester.pumpAndSettle(); // Verify modal content expect(find.text('Forgot Password'), findsOneWidget); }); Similarly, you can test the navigation triggered by the Sign Up link:Widget Test: Tap on Sign Up and navigates to the Sign Up screentestWidgets('Tap on Sign Up and navigates to the Sign Up screen', (WidgetTester tester) async { await tester.pumpWidget(createTestScreenWidget(SignInScreen())); final signUpTextFinder = find.text(Strings.signUp); await tester.tap(signUpTextFinder); await tester.pumpAndSettle(); // Verify navigation expect(find.byType(SignUpScreen), findsOneWidget); });These tests ensure your app’s routes are functioning correctly.Debugging Common IssuesDuring widget testing, you might encounter common errors like RenderFlex overflow or issues with animations. Suppressing these in tests, as shown below, can help: Flutter Error HandlingFlutter Error HandlingFlutterError.onError = (FlutterErrorDetails details) { if (details.exceptionAsString().contains('A RenderFlex overflowed')) { return; // Suppress the error } FlutterError.presentError(details); }; Best Practices for Widget Testing in Flutter Test Small Units: Widget tests should be granular, focusing on small components. This ensures that errors can be easily traced to individual widgets. Mock External Dependencies: When widget testing in Flutter, try to isolate the widget from any external dependencies such as APIs or services. This is achieved using mock data or mock functions. Use Golden Tests: Golden tests can be helpful to ensure your widget matches an expected visual appearance. Golden testing captures the rendered widget as an image and compares it to a reference image to catch unintended UI changes. Run Tests Regularly: Widget tests should be run frequently as part of your CI/CD pipeline to catch bugs early and maintain UI stability.Advantages of Widget Testing in Flutter Faster Execution Reliable Feedback Cost-Efficient Debugging Widget tests run much faster compared to integration tests, as they do not require the full app context to be loaded.Since widget tests run in isolation, they provide highly reliable feedback on individual component behavior without interference from other parts of the application.Early detection of UI bugs prevents costly reworks down the line, especially as your Flutter application scales in complexity.ConclusionWidget testing in Flutter is an indispensable tool for ensuring the reliability and correctness of user interface components. By incorporating widget testing into your development and quality assurance workflows, you can confidently validate the behavior of your app’s building blocks, ultimately delivering a better experience to your users. From understanding the basics to writing comprehensive tests and following best practices, this guide serves as a roadmap for mastering widget testing in Flutter.To take your testing knowledge further, explore our next guide on Integration Testing in Flutter, where we dive deeper into testing complete workflows and interactions within your app. Integration Testing in Flutter Flutter integration testing is a crucial step in ensuring that your app works seamlessly as a whole. It allows us to verify user flows, interactions between widgets, and the final output as seen by the user. In this guide, I’ll walk you through the process of creating an integration test for a Flutter app using a complete flow from a WelcomeScreen to a HomeScreen. By focusing on the text fields, buttons, and navigation routes, we’ll simulate real-world user interactions. If you’re looking to strengthen your Flutter testing toolkit, this is a great place to start.What is Integration Testing in Flutter?Integration testing in Flutter bridges the gap between unit tests and end-to-end tests. While unit tests validate individual methods or widgets, integration tests validate entire user flows across screens. This ensures the components work together harmoniously.Let’s take a practical example: a Sign In flow. We’ll verify that all interactive elements, such as text fields and buttons, function correctly. Additionally, we’ll ensure the navigation routes transition the user seamlessly between screens. Our integration test will involve three screens: WelcomeScreen , SignInScreen , and HomeScreen . Flutter Integration Test Running On iPhoneSetting Up Flutter Integration TestingWe begin with the following Flutter widget code. It sets up three key screens: WelcomeScreen: The starting screen offering options to [direction]Sign In[/direction] or [direction]Sign Up[/direction]. SignInScreen: The screen where users input their credentials. HomeScreen: The destination screen once a user signs in successfully.Writing Your First Integration TestTo start, create a new file in the integration_test directory, such as sign_in_screen_e2e_test.dart. This file will define tests to interact with the sign screen, simulating user flows like signing in. Flutter Integration Test File NameBegin by importing the necessary packages, including flutter_test for testing, integration_test for simulating interactions, and main.dart from your app. Use an alias like app for main.dart to avoid naming conflicts and make it clear you’re referencing your app’s entry point.Initialize the integration test environment by calling IntegrationTestWidgetsFlutterBinding.ensureInitialized(). This setup allows you to simulate real-world app usage.Integration Test – main.dart as appimport 'package:flutter/material.dart'; import 'package:flutter_test/flutter_test.dart'; import 'package:integration_test/integration_test.dart'; import 'package:get/get.dart'; import 'package:richapp/routes/routes.dart'; import 'package:richapp/main.dart' as app; void main() { IntegrationTestWidgetsFlutterBinding.ensureInitialized(); //...Testing the WelcomeScreenThe first step in our test is verifying the WelcomeScreen UI elements and functionality. The test checks if SIGN IN and SIGN UP buttons are displayed and functional. Inside the testWidgets function, call app.main() to launch your app. Flutter App Welcome ScreenWelcome Screen ElementstestWidgets('Complete flow from WelcomeScreen to HomeScreen', (WidgetTester tester) async { // Builds and loads the test app app.main(); // Wait for the WelcomeScreen to load await tester.pumpAndSettle(); // Verify WelcomeScreen is displayed expect(find.text('SIGN IN'), findsOneWidget); expect(find.text('SIGN UP'), findsOneWidget); // Tap the Sign In button on the WelcomeScreen await tester.tap(find.text('SIGN IN')); //await tester.pumpAndSettle(); await tester.pump(Duration(milliseconds: 1000)); //... The expect assertions confirm the presence of buttons, and tap simulates the user’s action of tapping SIGN IN .Testing the Sign In ScreenAfter navigating to the SignInScreen, the test verifies the presence of input fields for email and password, as well as the SIGN IN button. iPhone: Sign In ScreenSignIn Screen Elements// Verify SignInScreen is displayed expect(find.byKey(Key('email_username')), findsOneWidget); expect(find.byKey(Key('password')), findsOneWidget); expect(find.byKey(Key('sign_in_btn')), findsOneWidget); // Enter email and password await tester.enterText(find.byKey(Key('email_username')), 'test@example.com'); await tester.enterText(find.byKey(Key('password')), 'password123'); await tester.pump(Duration(milliseconds: 1000)); // Tap the Sign In button await tester.tap(find.byKey(Key('sign_in_btn'))); await tester.pump(Duration(milliseconds: 1000)); //...The enterText method mimics typing credentials into the fields.Testing the HomeScreen Finally, the test validates navigation to the HomeScreen and confirms key UI elements like the AppBar, Dashboard text, and menu icon are present. iPhone: Home ScreenHome Screen Elements// Simulate navigation to HomeScreen Get.toNamed(Routes.bottomNavigationScreen); await tester.pump(Duration(milliseconds: 1000)); // Verify HomeScreen is displayed expect(find.byType(AppBar), findsOneWidget); expect(find.text('Dashboard'), findsOneWidget); expect(find.byKey(Key('menu-icon')), findsOneWidget); //...By checking for these elements, we confirm that the user has successfully reached the HomeScreen.Run Testflutter test integration_test/app_test.dartBest Practices for Integration Testing in Flutter Use Realistic Data When performing integration testing in Flutter, it is best to use realistic test data that mimics real-world scenarios. This helps in identifying issues that could occur in actual usage, such as invalid user input or poor network conditions. Test Complete User Journeys Integration tests should cover complete user journeys rather than isolated actions. For instance, testing a purchase flow should cover product selection, adding to the cart, and completing the checkout. This ensures that all interactions and dependencies between components are working correctly. Optimize Test Execution Time Integration tests can take longer to run compared to unit tests. Make sure to optimize your tests by avoiding unnecessary waits and focusing on critical user flows. This reduces the time required for continuous integration and helps maintain productivity. Device Compatibility Flutter integration tests should be run on both Android and iOS to ensure compatibility across platforms. Consider using cloud-based testing services, such as Firebase Test Lab, to automate the execution of integration tests on a variety of devices.Common Challenges in Integration TestingWhile integration testing in Flutter is immensely valuable, it comes with its challenges. Managing Dependencies Maintenance Managing dependencies such as network responses can be cumbersome. To solve this, consider mocking or stubbing API calls to ensure tests are deterministic and can run without external dependencies. As the Flutter app undergoes changes, your integration tests may need frequent updates to align with new layouts or interactions. To mitigate this, ensure your tests are modular and maintainable.ConclusionIntegration testing in Flutter is a key component of building robust, high-quality mobile applications. By ensuring that all parts of the app work seamlessly together, you reduce the risk of unexpected issues arising in production. Setting up integration tests using the integration_test package allows QA testers and developers to verify entire user flows, enhancing app stability and improving user experience.Keep exploring and integrating Flutter integration testing into your development process.

Writing Your First Test Case with JUnitWriting your first test case with JUnit is a significant milestone. This guide walks you through creating a simple test case, executing it, and understanding the results. We will use basic JUnit annotations and assertions.Creating a Simple Test CaseCreate a Java Class: Create a new Java class, Calculator.java, with a method to be tested: public class Calculator { public int add(int a, int b) { return a + b; } } 2. Create a Test Class: Create a test class, CalculatorTest.java: import org.junit.Test; import static org.junit.Assert.*; public class CalculatorTest { @Test public void testAdd() { Calculator calculator = new Calculator(); int result = calculator.add(2, 3); assertEquals(5, result); } } 3. Run the Test: Execute the test class using your IDE or build tool. The test should pass, indicating the add method works correctly.Understanding JUnit Annotations@Test: Marks a method as a test case.@Before: Runs before each test case.@After: Runs after each test case.@BeforeClass: Runs once before all test cases.@AfterClass: Runs once after all test cases.Understanding AssertionsAssertions validate the test results. Common assertions include:assertEquals(expected, actual): Checks if two values are equal.assertTrue(condition): Checks if a condition is true.assertFalse(condition): Checks if a condition is false.assertNotNull(object): Checks if an object is not null.ConclusionYou have successfully written and executed your first JUnit test case. Understanding basic annotations and assertions is crucial for effective testing. In the next guide, we will delve deeper into JUnit assertions and annotations, enhancing your testing skills. Understanding JUnit Assertions and AnnotationsAssertions and annotations are the building blocks of JUnit tests. This guide provides a comprehensive overview of commonly used assertions and annotations, helping you write more expressive and organized tests.Common JUnit AssertionsassertEquals(expected, actual): Verifies that two values are equal.assertNotEquals(unexpected, actual): Verifies that two values are not equal.assertTrue(condition): Verifies that a condition is true.assertFalse(condition): Verifies that a condition is false.assertNull(object): Verifies that an object is null.assertNotNull(object): Verifies that an object is not null.assertSame(expected, actual): Verifies that two objects refer to the same instance.assertNotSame(unexpected, actual): Verifies that two objects do not refer to the same instance.Advanced AssertionsassertArrayEquals(expectedArray, actualArray): Verifies that two arrays are equal.assertThrows(expectedType, executable): Verifies that a specific exception is thrown.JUnit Annotations@Test: Marks a method as a test case.@Before: Executes before each test case to set up the test environment.@After: Executes after each test case to clean up the test environment.@BeforeClass: Executes once before all test cases in a class.@AfterClass: Executes once after all test cases in a class.@Ignore: Ignores a test case.Practical Example import org.junit.Before; import org.junit.Test; import static org.junit.Assert.*; public class CalculatorTest { private Calculator calculator; @Before public void setUp() { calculator = new Calculator(); } @Test public void testAdd() { assertEquals(5, calculator.add(2, 3)); } @Test public void testSubtract() { assertEquals(1, calculator.subtract(3, 2)); } } ConclusionUnderstanding and using JUnit assertions and annotations effectively is essential for writing robust tests. The next guide will focus on testing exceptions in JUnit, a critical aspect of ensuring your code handles error conditions gracefully. Testing Exceptions in JUnitTesting exceptions in JUnit ensures your code handles error conditions correctly. This guide explains how to use JUnit to verify that your methods throw the expected exceptions under specific conditions.Using expected Parameter in @TestYou can specify the expected exception type using the expected parameter in the @Test annotation: @Test(expected = IllegalArgumentException.class) public void testException() { Calculator calculator = new Calculator(); calculator.divide(1, 0); } Using assertThrows MethodJUnit 5 introduces the assertThrows method, providing more flexibility: import static org.junit.jupiter.api.Assertions.*; @Test public void testException() { Calculator calculator = new Calculator(); assertThrows(IllegalArgumentException.class, () -> { calculator.divide(1, 0); }); } Practical Example public class Calculator { public int divide(int a, int b) { if (b == 0) { throw new IllegalArgumentException("Division by zero"); } return a / b; } } @Test(expected = IllegalArgumentException.class) public void testDivideByZero() { Calculator calculator = new Calculator(); calculator.divide(1, 0); } @Test public void testDivideByZeroWithAssertThrows() { Calculator calculator = new Calculator(); IllegalArgumentException thrown = assertThrows(IllegalArgumentException.class, () -> { calculator.divide(1, 0); }); assertEquals("Division by zero", thrown.getMessage()); } ConclusionTesting exceptions is vital for ensuring your code handles errors gracefully. The next guide will cover using JUnit test suites to organize tests, helping you manage and execute your tests efficiently. Using JUnit Test Suites to Organize TestsJUnit test suites allow you to group and organize related test cases for efficient execution. This guide explains how to create and use test suites in JUnit, enhancing your test management and execution strategy.Creating a Test Suite in JUnit 4Create a Test Suite Class: import org.junit.runner.RunWith; import org.junit.runners.Suite; @RunWith(Suite.class) @Suite.SuiteClasses({ CalculatorTest.class, AnotherTest.class }) public class AllTests { } 2. Run the Test Suite: Execute the AllTests class using your IDE or build tool. It will run all specified test classes.Creating a Test Suite in JUnit 5Create a Test Suite Class: import org.junit.platform.suite.api.IncludeClasses; import org.junit.platform.suite.api.Suite; @Suite @IncludeClasses({CalculatorTest.class, AnotherTest.class}) public class AllTests { } 2. Run the Test Suite: Execute the AllTests class using your IDE or build tool.Practical Example // CalculatorTest.java public class CalculatorTest { // Test methods } // AnotherTest.java public class AnotherTest { // Test methods } // AllTests.java @RunWith(Suite.class) @Suite.SuiteClasses({ CalculatorTest.class, AnotherTest.class }) public class AllTests { } Benefits of Using Test SuitesOrganized Testing: Groups related tests for better organization.Efficient Execution: Executes multiple test classes together.Simplified Management: Manages tests more efficiently, especially in large projects.ConclusionUsing JUnit test suites improves your test management and execution strategy. This guide completes your introduction to essential JUnit features. For more advanced topics, continue exploring JUnit’s extensive capabilities to enhance your testing practices.
Writing Your First Test Case with Appium Now that you have Appium set up on your local machine, it’s time to dive into writing your first test case. This guide will walk you through the process of creating a simple test case in Java.Create a New Maven ProjectUse your favorite IDE to create a new Maven project. We’re going to be using Eclipse in this setup. Eclipse IDE LaunchingCreating A New ProjectStart a new project by navigating to the top menu and selecting File then New and finally Other...

To proceed, click the checkbox labeled Create a simple project (skip archetype selection). Once you have checked this option, click the Next > button to move forward with the project setup. Check The Create A Simple Project BoxOn the next step of the wizard, you will need to create a group ID and an artifact ID for your project. For this guide, use com.test.app.todo as both the group ID and artifact ID. Enter these values in the respective fields provided. After filling in the details, click the Finish button to continue. Create a Group Id & Artifact Id nameCreate a New Test ClassWith our Maven project created, the next step is to create a new test class. Navigate to the directory src/test/java/. Inside this directory, create a new package by following this path: com.test. Create A New Package To Store Your Test Files Setting 'com.test' As A Package NameOnce the package is created, add a new class within it and name the class FirstAppiumTest. Creating A New Class Set The Class Name As FirstAppiumTest The FirstAppiumTest Class Is CreatedAdd Dependencies to pom.xmlNow, navigate to the pom.xml file in your project. This file is essential for managing your project’s dependencies and configurations. Open the pom.xml file, as we will be adding the necessary dependencies to run an Appium test script. Once the file is open, so we can add the xml dependencies below.pom.xml<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>test-todo-app</groupId> <artifactId>test-todo-app</artifactId> <version>0.0.1-SNAPSHOT</version> <properties> <maven.compiler.source>17</maven.compiler.source> <maven.compiler.target>17</maven.compiler.target> </properties> <dependencies> <dependency> <groupId>io.appium</groupId> <artifactId>java-client</artifactId> <version>8.3.0</version> </dependency> <dependency> <groupId>org.seleniumhq.selenium</groupId> <artifactId>selenium-java</artifactId> <version>4.7.0</version> </dependency> <dependency> <groupId>org.seleniumhq.selenium</groupId> <artifactId>selenium-remote-driver</artifactId> <version>4.7.0</version> </dependency> <dependency> <groupId>org.hamcrest</groupId> <artifactId>hamcrest</artifactId> <version>2.2</version> <scope>test</scope> </dependency> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.11.0</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <version>3.0.0-M5</version> </plugin> </plugins> </build> </project>Add Your APK To The ProjectTo add your test APK to your project, begin by creating a new directory within your project’s structure. Navigate to the src/test/resources/ directory. Within this directory, create a new folder named app. This is where you will store your APK file for testing purposes. Create A New Folder To Store The Test App Setting The Directory As 'App' Added The Test App In The 'App' FolderWrite Your First Test ScriptLet’s take a look at our test application and discuss the test scenario that we’ll be automating. The test application we’ll be using is a TODO app. If you need access to the APK file, please join our Patreon. Members get access to all the existing frameworks we’ve created and more. You can follow along with this guide or use your own test application and tweak the elements as needed. In this test, our goal is to simply click on the Add Task button to display the Add Task screen. Add A Task Button Viewing Add Task ScreenFirstAppiumTest.javapackage com.test; import io.appium.java_client.android.AndroidDriver; import org.openqa.selenium.By; import org.openqa.selenium.WebElement; import org.openqa.selenium.remote.DesiredCapabilities; import java.io.File; import java.net.MalformedURLException; import java.net.URL; public class FirstAppiumTest { public static void main(String[] args) throws MalformedURLException, InterruptedException { File app = new File("src/test/resources/app/app-debug.apk"); // Set the desired capabilities for your test DesiredCapabilities caps = new DesiredCapabilities(); caps.setCapability("deviceName", "emulator-5554"); caps.setCapability("platformName", "android"); caps.setCapability("app",app.getAbsolutePath()); // Initialize the Appium driver AndroidDriver driver = new AndroidDriver (new URL("http://127.0.0.1:4273/wd/hub"), caps); // Add test case scenario here WebElement addTaskButton = driver.findElement(By.id("ADD_YOUR_ID_HERE")); addTaskButton.click(); // quick debug wait for 1 seconds Thread.sleep(1000); // Close the driver session driver.quit(); } }Launch Appium Desktop & Appium InspectorNow, we need to find the id associated with the element that we want to click. To locate the id element or other useful selectors, ensure that the emulator or device is booted up. First, launch the Appium Server and Inspector. Open the Appium Desktop Server and click the startServer button. Next, launch the Appium Inspector, making sure that the server port matches the Appium server’s port. Appium Desktop with Emulator Appium Server Is Running Appium Inspector + Setting Up Desired Capabilities Ensure the Remote Port is set to 4273 Set the Remote Path to /wd/hub Click the pencil & Copy the Desired Capabilities from below and paste in the JSON Representation box Click the Save button Click the Start Session button Desired Capabilities JSON DesiredCapabilities.json{ "appium:platformName": "Android", "appium:platformVersion": "13.0", "appium:deviceName": "emulator-5554", "appium:automationName": "UiAutomator2", "appium:app": "/Users/{userName}/eclipse-workspace/test-todo-app/src/test/resources/app/app-debug.apk", "appium:appWaitForLaunch": true }Inspecting The App ElementsWith the Appium Inspector now launched, you should see a preview of your application. In the preview window, locate and click on the element for which you want to retrieve attributes. For the purposes of this guide, we will click on the Add Task button. By doing so, the attributes related to this specific element will be displayed, allowing you to inspect and utilize them as needed. Appium Inspector Viewing The Element's Properties The accessibility id: value is to Add Task The id: value is to com.example.todoapp:id/fab The xpath: value is to //android.widget.ImageButton[@content-desc="Add Task"]You have the flexibility to use any available selector, but for this guide, we will select the second option, which represents the id attribute with the value com.example.todapp:id/fab. This value will be used in our code. Close the Appium Inspector Session to free up the Appium Server 4273 port.Copy this id value and navigate to the FirstAppiumTest class in your project. Find the element designated for adding a task and paste the copied id value into the addTaskButton element. This ensures that our test script can correctly interact with the element. Finding Add Task Button Element By IDJavaWebElement addTaskButton = driver.findElement(By.id("com.example.todoapp:id/fab")); addTaskButton.click(); // quick debug wait for 1 seconds Thread.sleep(1000); System.out.println("TEST PASSED!"); // Close the driver session driver.quit();Run Your TestFinally, it’s time to run the script. Yay! In the FirstAppiumTest class, right-click to open the context menu. Navigate to Run As and select Java Application. Now, sit back and watch as your script takes off for the first time! If everything goes well, you will see TEST PASSED in the console. Appium Run As Java ApplicationAnalyze the Test ResultsAfter the test execution is complete, review the results to ensure your test case ran successfully. Later in this series, we will learn how to implement TestNG to organize tests based on industry standards. Test Results - Passed Running Appium Test ScriptConclusionYou have now learned how to perform basic UI testing with Appium. This includes finding elements and performing actions. In the next guide, we’ll take a closer look at Organizing Multiple Test Scenarios In Appium with TestNG.
Organizing Multiple Test Scenarios in Appium Using TestNG In the dynamic world of mobile application testing, managing and organizing multiple test scenarios efficiently is crucial for ensuring robust and reliable testing. Appium, combined with TestNG, provides a powerful framework to achieve this. This guide will walk you through the process of organizing multiple test scenarios in Appium using TestNG, leveraging the power of Java. Whether you’re a beginner or an advanced user, this comprehensive guide will help you streamline your test automation process and enhance your testing capabilities. We will be using the project we setup previously. Setting Up Maven ProjectLet’s navigate to the pom.xml file so we can add the TestNG dependency. We’ll be using TestNG version 7.1.0 for our project. Adding TestNG Dependency To pom.xmlTestNG Dependency (pom.xml)<dependency> <groupId>org.testng</groupId> <artifactId>testng</artifactId> <version>7.1.0</version> <scope>compile</scope> </dependency>By adding the TestNG dependency to your Maven project, you now have the necessary annotations to write and execute TestNG tests within the Appium project.Creating TestNG Class Let’s head back to our directory /src/test/java/com/test/ where we’ll create a copy of the existing FirstAppiumTest class. We’ll then rename this copy to FirstAppiumTestNG to begin restructuring the test to support TestNG. This new class will serve as our foundation for integrating TestNG functionalities. Copying FirstAppiumTest Class Pasting FirstAppiumTest Class Rename Copied File to FirstAppiumTestNGImporting TestNG AnnotationsIn the newly created FirstAppiumTestNG class, begin by importing the necessary TestNG annotations. These will include @BeforeClass, @AfterClass, and @Test.FirstAppiumTestNG.classimport org.testng.annotations.AfterClass; import org.testng.annotations.BeforeClass; import org.testng.annotations.Test; The @BeforeClass annotation will be used to set up the Appium driver before any tests are run, ensuring that the environment is correctly initialized. Similarly, the @AfterClass annotation will handle the teardown process, cleaning up resources once all tests have been executed. The @Test annotation will be applied to individual test methods, marking them as TestNG test cases.Modifying Class To Support TestNGSo what we’re going to do is remove the main() function call and close the curly bracket from our initial setup. Next, we will create a new public static AndroidDriver variable called driver. BeforeClassIn the @BeforeClass method, we will move the Desired Capabilities setup into the setup() function. This approach ensures that our Appium driver is properly configured before any tests are execute. Moving Desired Capabilities To BeforeClass MethodTest MethodIn the @Test method, we will add our simple test case from the previous guide, which is to click the Add Task button. This test will validate that our application responds correctly when adding a new task. By organizing our tests this way, we maintain a clear separation of concerns, making our test cases easier to manage and understand. Moving Scenario To Test MethodAfterClass MethodFinally, we’ll move the driver.quit() function into the @AfterClass teardown method. This adjustment ensures that the Appium driver is properly closed after all tests have been executed, cleaning up any resources used during the test run. Moving The Closing of the Driver in AfterClass MethodFirstAppiumTestNG.class (w/ Before & After Methods)package com.test; import io.appium.java_client.android.AndroidDriver; import org.openqa.selenium.By; import org.openqa.selenium.WebElement; import org.openqa.selenium.remote.DesiredCapabilities; import java.io.File; import java.net.MalformedURLException; import java.net.URL; import org.testng.annotations.AfterClass; import org.testng.annotations.BeforeClass; import org.testng.annotations.Test; public class FirstAppiumTestNG { public static AndroidDriver driver; @BeforeClass public void setUp() throws MalformedURLException { File app = new File("src/test/resources/app/app-debug.apk"); // Set the desired capabilities for your test DesiredCapabilities caps = new DesiredCapabilities(); caps.setCapability("deviceName", "emulator-5554"); caps.setCapability("platformName", "android"); caps.setCapability("app",app.getAbsolutePath()); // Initialize the Appium driver driver = new AndroidDriver (new URL("http://127.0.0.1:4273/wd/hub"), caps); } @Test public void clickingAddTaskButton() throws InterruptedException { // Add test case scenario here WebElement addTaskButton = driver.findElement(By.id("com.example.todoapp:id/fab")); addTaskButton.click(); // quick debug wait for 1 seconds Thread.sleep(1000); System.out.println("TEST PASSED!"); } @AfterClass public void tearDown() { if (driver != null) { // Close the driver session driver.quit(); } } }Adding More Test & AssertionsWhy stop here? Next, we’ll add some assertions and create two more test scenarios to highlight the beauty of TestNG running multiple scenarios and validating our expectations. We will create new tests called addingTaskToDoTheList() and deletingTaskFromTheList(), similar to the test we created using Espresso in our Android guides. We will add these methods to our file, and then we should be ready to run our tests.In our first new test scenario, we focus on adding a task to our to-do list. This test begins by clicking the “Add Task” button to navigate to the task addition screen. We verify that the user is on the correct screen by checking the presence of the title input field. Here’s how the implementation looks:Test: clickingAddTaskButton()@Test public void clickingAddTaskButton() throws InterruptedException { // Add test case scenario here WebElement addTaskButton = driver.findElement(By.id("com.example.todoapp:id/fab")); addTaskButton.click(); // quick debug wait for 2 seconds Thread.sleep(2000); WebElement addTaskTitle = driver.findElement(By.id("com.example.todoapp:id/titleEditText")); Assert.assertTrue(addTaskTitle.isDisplayed(), "User is on the Add Task Details Screen"); driver.navigate().back(); Thread.sleep(1000); }addingTaskToDoTheList() TestNext, we have the addingTaskToDoTheList() method, which adds a task to the to-do list. This method clicks the “Add Task” button, enters a title and description for the new task, and then saves it. After saving, it verifies that the new task appears in the task list.Test: addingTaskToDoTheList()@Test public void addingTaskToDoTheList() throws InterruptedException { WebElement addTaskButton, saveButton; WebElement addTaskTitleField, addTaskDescField; // click the Add Task button addTaskButton = driver.findElement(By.id("com.example.todoapp:id/fab")); addTaskButton.click(); // quick debug wait for 2 seconds Thread.sleep(2000); // add title to the task addTaskTitleField = driver.findElement(By.id("com.example.todoapp:id/titleEditText")); addTaskTitleField.click(); addTaskTitleField.sendKeys("Buy Milk"); // add description to the task addTaskDescField = driver.findElement(By.id("com.example.todoapp:id/descriptionEditText")); addTaskDescField.click(); addTaskDescField.sendKeys("Grab 2 Gallons of Milk"); // click the Save button saveButton = driver.findElement(By.id("com.example.todoapp:id/saveButton")); saveButton.click(); // quick debug wait for 2 seconds Thread.sleep(2000); WebElement newTaskAdded = driver.findElement(By.id("com.example.todoapp:id/textView")); Assert.assertEquals(newTaskAdded.getText().toString(), "Buy Milk", "New Task Found"); }deletingTaskFromTheList() TestFinally, we have the deletingTaskFromTheList() method, which tests the deletion of a task from the list. This method locates the delete button and clicks it, then verifies that the task is removed from the task list.Test: deletingTaskFromTheList()@Test public void deletingTaskFromTheList() throws InterruptedException { WebElement deleteButton; // click the Delete button deleteButton = driver.findElement(By.id("com.example.todoapp:id/doneButton")); deleteButton.click(); // quick debug wait for 2 seconds Thread.sleep(2000); Assert.assertTrue(true, "Task is deleted & is removed from the Task List Screen"); }Full ImplementationHere’s the full implementation of the FirstAppiumTestNG file.

In this new file, we’ll add the XML code below to enable running our FirstAppiumTestNG class.TestNG Suite Config (testng.xml)<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd"> <suite name="My First Appium TestNG Test"> <test name="TODO App Automation Testing"> <classes> <class name="com.test.FirstAppiumTestNG"/> </classes> </test> <!-- Test --> </suite> <!-- Suite --> Create A New TestNG File Naming The File testng.xml Pasting The XML Script In The New Testng.xml FileTo properly run our TestNG XML file, we need to configure the pom.xml file accordingly. Start by opening your pom.xml file and locating the Maven Surefire Plugin section. Within this section, you’ll need to add the TestNG configuration. Specifically, scroll down to where you see the <version> tag within the Maven Surefire Plugin and insert the following configuration just below it:TestNG Suite Setup (pom.xml)<configuration> <suiteXmlFiles> <suiteXmlFile>testng.xml</suiteXmlFile> </suiteXmlFiles> <testFailureIgnore>false</testFailureIgnore> </configuration> Pasting TestNG XML ConfigurationThis snippet tells Maven to use the testng.xml file to determine which tests to run. The <testFailureIgnore> tag is set to false, ensuring that the build will fail if any test fails, which is often the desired behavior in a continuous integration environment.Once you’ve added this configuration, make sure to save your pom.xml file. With these changes in place, your project is now ready to run with the specified TestNG configuration. Let's open the Terminal in Eclipse so we can execute the Maven command. Type or copy the command mvn test -DsuiteXmlFile=testng.xml into the Terminal. Press Enter to execute. The script should begin running the three scenarios we created earlier. As the tests execute, you should see passing logs appear in the console, indicating successful execution.

Understanding Appium UI Locator Strategies In this guide, we will delve into Appium UI Locator Strategies. Understanding how to efficiently locate elements is crucial for creating robust and maintainable automated tests. This guide is designed to be comprehensive and accessible for both beginners and advanced users. By the end of this guide, you’ll be proficient in various locator strategies in Appium, using Java as our code language.Introduction to LocatorsLocators are used to find UI elements on the mobile application. Appium supports various locator strategies: ID - is a unique identifier for elements. It is one of the most reliable and fastest ways to locate elements. Name - is another attribute that can be used, although it's less common and sometimes deprecated. Class Name - locates elements by their class attribute. It can return multiple elements, so it's often used with other strategies. XPath - is a powerful and flexible locator strategy but can be slower and more brittle. It's often used when other locators are not available. iOS Predicate String (iOS) - iOS Predicate String is used for complex queries on iOS. iOS Class Chain (iOS) - iOS Class Chain is another iOS-specific strategy that allows chaining class names and attributes.Using ID Using an id is one of the most efficient ways to identify and capture elements in Appium, provided that this option is available in our inspector. The id attribute serves as a unique identifier for elements within the DOM, allowing for precise and reliable element selection. This method is particularly advantageous because IDs are designed to be unique within a given page, thereby reducing the risk of selecting the wrong element.By.idWebElement taskButton = driver.findElement(By.id("add-task-button"));Using Name By using the name attribute, you ensure your code remains clear and intuitive. This method not only enhances readability but also reduces the risk of errors that can occur with more complex locators. It’s a straightforward way to improve your Appium testing strategy, making it easier to manage and scale your automated tests. Adopting this practice can lead to more robust and reliable test scripts, ultimately contributing to a more efficient development cycle.By.nameWebElement taskButton = driver.findElement(By.name("add-task-button"));Using XPath When using xpath to identify an element in Appium, you can target specific attributes or hierarchical relationships within the UI structure. For example, you might want to locate a button based on its ID, class, or even its position relative to other elements. This flexibility is one of the key advantages of using xpath over other locating strategies.By.xpathWebElement taskButton = driver.findElement(By.xpath("//android.widget.Button[@content-desc='SIGN IN']"));Using Class Name You can capture and interact with an element by specifying its className. This method is particularly useful when elements share common characteristics or belong to the same class.By.classNameWebElement taskButton = driver.findElement(By.className("android.widget.Button"));[IOS] iOS Predicate StringThis technique offers a precise way to locate elements based on specific attributes. The iOS Predicate String is a powerful tool that leverages the NSPredicate class from Apple’s iOS development environment, allowing developers to create complex queries for UI elements.[IOS] iOS Class Chain This approach leverages the class chain strategy, providing a powerful alternative to traditional locator strategies. By utilizing iOSClassChain, developers can efficiently target elements based on their hierarchical structure, enhancing the precision of their UI automation tests.By.iOSClassChainWebElement taskButton = driver.findElement(By.iOSClassChain("**/XCUIElementTypeButton[`label == 'Task'`]"));ConclusionIn this guide, we explored various Appium UI locator strategies using Java. By mastering these locators, you can write efficient and reliable automated tests for your mobile applications. Remember to prioritize IDs and Accessibility IDs for their reliability and speed, and use XPath judiciously.

Writing Your First Patrol Test Case Patrol is an excellent tool for automating Flutter app tests, ensuring that essential app functionalities work as expected across various devices. In this guide, we will walk through writing your first Patrol test, specifically focusing on a common user journey: signing into an app.Setting Up Your Patrol TestBefore diving into the test, ensure that you have Patrol properly installed in your project. With everything in place, let’s begin by writing a test that checks the functionality of a basic sign-in screen. Welcome Screen Sign In ScreenThe sign-in screen typically includes email and password input fields, followed by a sign-in button. Our goal in this Patrol test is to automate the process of entering the email and password, tapping the sign-in button, and verifying the navigation to the dashboard screen.The test begins with a basic import of necessary packages, such as flutter_test for testing utilities and patrol for test automation:Dartimport 'package:flutter/material.dart'; import 'package:flutter_test/flutter_test.dart'; import 'package:patrol/patrol.dart'; import 'package:richpay_app/main.dart' as app;By importing these packages, you set up a testing environment that allows you to interact with the app’s widgets during test execution.Structuring the Patrol TestNext, we define our Patrol test. In this example, we are testing the sign-in process by creating a test that verifies the email input, password input, and sign-in button functionality:Dartvoid main() { patrolTest( 'Sign In Screen - Verifies email input, password input, and sign-in button', ($) async { // Start the app app.main(); await $.pumpAndTrySettle();The patrolTest function defines a specific test case, and inside the function, we start the app using app.main(). This ensures that your app runs in the testing environment, ready to simulate user interactions.Interacting with WidgetsAfter starting the app, we simulate a tap on the sign-in button that appears on the welcome screen. We use the find.byKey method to locate the button using its unique Key:Dartfinal welcomeSignInButton = $(find.byKey(const Key('sign_in_btn'))); await $(welcomeSignInButton).tap(); await $.pumpAndSettle();The $(find.byKey()) function finds the button, and tap() simulates the user pressing it. The pumpAndSettle() method ensures that the app has finished rendering and settles before the next step. Widget Inspector Sign In ButtonEntering Text into Input FieldsNow, let’s verify and interact with the email and password input fields. We first locate the input fields using their respective keys and then simulate entering text:Dartfinal emailTextBox = $(find.byKey(const Key('email_username'))); await $(emailTextBox).enterText('test@gmail.com'); final passwordTextBox = $(find.byKey(const Key('password'))); await $(passwordTextBox).enterText('test123');The enterText() function is essential in automating user input for testing login forms, ensuring that valid text is entered into the relevant fields during the test. Widget Inspector Email & PasswordFinalizing the Test by Tapping the Sign-In ButtonAfter entering the login credentials, we locate and tap the sign-in button to submit the form:Dartfinal signInSignInButton = $(find.byKey(const Key('sign_in_btn'))); await $(signInSignInButton).tap(); // Wait for the navigation to complete after sign-in await $.pumpAndSettle(); Just like before, we use find.byKey to locate the sign-in button and simulate the tap. The app is given time to navigate by calling pumpAndSettle() to ensure all animations and transitions are complete before continuing. Widget Inspector Sign In ButtonVerifying the DashboardFinally, after the sign-in process completes, we want to verify that the user has successfully navigated to the dashboard. We can do this by checking if a specific widget or text related to the dashboard is visible: Widget Inspector Verify Dashboard TextDartexpect(find.text('Dashboard'),findsOneWidget); In this case, we check if the text Dashboard is displayed, confirming that the sign-in was successful and the user has reached the dashboard screen.ConclusionIn the next guide, we’ll dive deeper into Organizing Test Suites in Patrol, helping you structure your tests efficiently for larger applications. Stay tuned for more best practices and techniques to optimize your mobile testing process with Patrol! Organizing Test Suites in Patrol Organizing your test suites efficiently is crucial for maintaining a clean, scalable, and maintainable test architecture, especially when using Patrol, a robust mobile testing framework. One effective strategy is to group tests by screen name, allowing you to organize tests into directories that correspond to the screens in your app. This practice not only improves clarity but also makes it easier for your QA team to locate and maintain specific test cases as your project evolves. Get Access to the Test App & FrameworkPro Members unlock hands-on access to our expertly crafted frameworks. PRO MEMBER Organizing Tests by Screen NameWhen testing a mobile application, screens often represent a core aspect of the user flow. Each screen might have different behaviors, elements, and functionalities that require unique test cases. By organizing tests by screen name, you ensure that: Tests are easily navigable: Team members can quickly find tests related to specific app screens. Reusability and maintenance are enhanced: Updates to screens or features can be isolated to relevant directories without impacting the entire test suite. Collaboration is smoother: Teams can focus on specific screens without having to comb through large, unrelated test files.Create Screen-Specific DirectoriesIn Patrol, you can organize your tests into directories that correspond to specific screens in your app. The following structure is an example:screen directoriesintegration_test/ └── e2e/ ├── dashboard/ │ └── dashboard_test.dart ├── menu/ │ └── menu_test.dart ├── notifications/ │ └── notifications_test.dart ├── profile/ │ └── profile_test.dart ├── sign_in/ │ └── sign_in_test.dart └── sign_up/ └── sign_up_test.dart Organizing Tests by Screen NameEach directory contains the relevant test files for that particular screen. This keeps the tests clean and organized. Here’s how each folder corresponds to the app: dashboard/: Tests focused on ensuring the functionality of the user dashboard. menu/: Tests for menu navigation, clicking and validating the menu items. notifications/: Tests to verify the functionality of the notification screen. profile/: Tests centered on user profile management, and updating personal details. sign_in/: Tests for the sign-in screen, focusing on logging in and error handling. sign_up/: Tests for the sign-up screen, ensuring registration is working as expected.Writing Tests for Each ScreenLet’s dive deeper into crafting a sample test for the dashboard screen. This test suite will encompass various tests to ensure that essential elements are displayed correctly, including the Dashboard title, key transfer functions such as Deposit, Withdraw, Send, and Request, as well as the transaction history components.dashboard_test.dartimport 'package:flutter/material.dart'; import 'package:flutter_test/flutter_test.dart'; import 'package:patrol/patrol.dart'; import 'package:richpay_app/main.dart' as app; void main() { patrolTest( 'Dashboard Screen - Verify the elements on the dashbaord', ($) async { // Start the app app.main(); await $.pumpAndTrySettle(); final welcomeSignInButton = $(find.byKey(const Key('sign_in_btn'))); await $(welcomeSignInButton).tap(); await $.pumpAndSettle(); // // Verify the presence of email/username input field and enter text final emailTextBox = $(find.byKey(const Key('email_username'))); await $(emailTextBox).enterText('test@gmail.com'); final passwordTextBox = $(find.byKey(const Key('password'))); await $(passwordTextBox).enterText('test123'); final signInSignInButton = $(find.byKey(const Key('sign_in_btn'))); await $(signInSignInButton).tap(); // Wait for the navigation to complete after sign-in await $.pumpAndSettle(); // Add further assertions if needed expect(find.text('Dashboard'), findsOneWidget); expect(find.text('Deposit'), findsAtLeast(1)); expect(find.text('Withdraw'), findsOneWidget); expect(find.text('Send'), findsOneWidget); expect(find.text('Request'), findsOneWidget); expect(find.text('Transactions History'), findsOneWidget); }, ); } Naming Conventions and Test FlowUsing consistent naming conventions is essential. Screen directories and test files should be named based on the screens they test. This eliminates confusion, especially as your test suite grows. For example: Patrol Test Based On Screen dashboard_test.dart: Tests related to the dashboard screen. profile_test.dart: Tests related to the profile screen.When writing these tests, ensure that: 1 Self Contained 2 Descriptive Test Names Each test is self-contained: A test should not rely on another test. This enhances the modularity of your test suite.Each test function should clearly describe the functionality being tested, such as verify_profile_update or test_sign_up_with_invalid_credentials. Running Tests by DirectoryPatrol allows you to run tests for a specific directory if you want to focus on tests for a particular screen. Here’s how to run tests for the sign_in screen using the CLI:Run all test in ‘sign_in’ directorypatrol test -t integration_test/e2e/sign_in/ Running Patrol Test Sign In Screen Directory Tip: Running On IOS?If you’re running your Patrol test on an iOS device, make sure to pass the -d flag followed by the device’s UDID. This ensures that the correct device is targeted and avoids any running issues that could occur if it’s omitted. For example:Using the Device Flag For iOSpatrol test -d D76D6C18-03AE-46E0-A732-C46608EBF212 -t integration_test/e2e/sign_inIn this command, D76D6C18-03AE-46E0-A732-C46608EBF212 is the UDID of your iOS device, and the -t flag is used to specify the test file, such as integration_test/e2e/sign_in.This command will execute all tests within the sign_in directory, making it easy to target specific areas of the app without running the entire test suite.ConclusionOrganizing test suites by screen name in Patrol helps maintain clean, efficient, and scalable test cases. By creating screen-specific directories, you enhance collaboration and streamline the testing process. This structure becomes especially helpful as your app grows and new features are added. Following this organization strategy ensures that your tests are well-structured, easy to manage, and scalable for future updates.In the next lesson, we’ll dive deeper into Organizing Test Suites by Screen Name in Patrol, where you’ll learn how to effectively categorize your tests and maintain a robust testing workflow. Advanced and Native Interactions in Patrol In the realm of mobile testing, achieving seamless user interactions is paramount to ensuring a smooth user experience. Patrol Testing provides an effective framework for automating and validating these interactions, including both advanced and native functionalities. This guide explores the intricacies of advanced and native interactions in Patrol, offering insights into best practices, techniques, and methodologies to elevate your testing strategies.Advanced InteractionsAdvanced interactions in Patrol Testing encompass a variety of user actions that simulate complex user behaviors. These interactions are crucial for ensuring that applications function as intended in real-world scenarios. Here are some key types of advanced interactions:GesturesGestures such as swipes, pinches, and rotations play a crucial role in navigating and interacting with mobile applications. These gestures simulate the natural user interactions within an app, and automating them ensures your tests closely mimic real-world usage scenarios. Patrol makes it easy to automate gestures with its intuitive syntax, allowing testers to seamlessly simulate complex interactions such as swipes.Swipe Left// Verify the first card is visible initially expect(find.byType(CardWidget), findsWidgets); // Swipe left to scroll right through the cards await $.tester.drag(find.byType(CarouselSlider), const Offset(-300, 0)); await $.pumpAndSettle();A left swipe action mimics the user’s gesture of dragging the screen to the left, often used to reveal the next set of items in a carousel or slider. Swiping Left in Patrol Card Verification: The test first checks if the CardWidget is visible. Swipe Action: The swipe is performed by dragging the CarouselSlider with an offset of -300 on the X-axis, which simulates a leftward swipe. Settling: After the swipe, we call await $.pumpAndSettle(); to allow the animations or transitions to complete.Swipe Right// Verify the first card is visible initially expect(find.byType(CardWidget), findsWidgets); // Swipe right to scroll right through the cards await $.tester.drag(find.byType(CarouselSlider), const Offset(300, 0)); await $.pumpAndSettle();Similarly, a right swipe mimics the user’s gesture of dragging the screen to the right, often to scroll back to the previous items in the carousel. Swiping Right in Patrol Card Verification: The test first checks if the CardWidget is visible. Swipe Action: The swipe is performed by dragging the CarouselSlider with an offset of 300 on the X-axis, which simulates a rightward swipe. Settling: After the swipe, we call await $.pumpAndSettle(); to allow the animations or transitions to complete.Double TapCertain functionalities depend on double tap actions. Patrol currently doesn’t have built-in method for doubleTapping on an element. In this scenario we will use the tap feature twice. Tip: Double Tap in Patrol TestingPatrol doesn’t have a built-in doubleTap method for interacting with Flutter widgets in the app. However, Patrol provides a $.native.doubleTap feature, which is specifically used for WebViews and elements that are native to the device itself, rather than elements within the Flutter app. To simulate a double-tap in a Flutter app, you can manually call tap twice with a small delay in between.Double Tapawait $.tap(find.text('Double Tap for App Info')); await $.tap(find.text('Double Tap for App Info')); expect(find.text('Rich Pay v2.0.0 | Patrol Version 3.2.0'), findsOneWidget);This command allow you to validate double taps and the expectation ensuring comprehensive coverage of user actions. Mimicking DoubleTap FeatureNative InteractionsNative interactions refer to the ability to interact with platform-specific features and components, significantly enhancing the overall user experience by testing your application in real-world scenarios. Patrol provides robust support for accessing and interacting with native functionalities on both Android and iOS devices. This feature allows testers to simulate device-level interactions, ensuring that applications behave correctly under various system conditions.Accessing Device FeaturesPatrol allows you to interact with several native device features, such as WiFi, GPS, dark mode, and system dialogs. These interactions are invaluable for testing how your app reacts to changes in device settings or permissions. For instance, when testing a weather app that relies on location services, you can simulate turning GPS on and off, or granting and denying location permissions.Below is a sample code that demonstrates how you can access and manipulate some of these native features:Native FeaturespatrolTest('demo', (PatrolIntegrationTester $) async { await $.pumpWidgetAndSettle(AwesomeApp()); // prepare network conditions await $.native.enableCellular(); await $.native.disableWifi(); // toggle system theme await $.native.enableDarkMode(); // handle native location permission request dialog await $.native.selectFineLocation(); await $.native.grantPermissionWhenInUse(); // tap on the first notification await $.native.openNotifications(); await $.native.tapOnNotificationByIndex(0); });Interacting with Native Alerts and DialogsMany applications utilize native alerts and dialogs for user notifications or confirmations. Patrol can handle these interactions effectively:System Dialog > Grant Permissionif (await $.native.isPermissionDialogVisible()) { await $.native.grantPermissionWhenInUse(); } Patrol Grant Access To System PromptThis sequence ensures that your tests can manage alerts, providing a seamless user experience.ScrollingTesting native scrolling is crucial for applications with long lists or multiple screens. Patrol facilitates these actions with simple commands:scrollToawait $(find.byKey(Key('request-tab'))).tap(); await $.pumpAndSettle(); await $(find.text('CONTINUE')).scrollTo(); await $(find.text('CONTINUE')).tap(); Patrol ScrollTo FeatureInteracting with WebViewsWebViews are a common element in mobile applications, allowing developers to display web content within a native app. Testing WebViews can be challenging due to the mixed nature of web elements inside a native container, but Patrol provides efficient ways to interact with them. This guide will walk you through testing WebView elements using Patrol, ensuring your app’s web interactions work seamlessly.WebViews// Tap on the button that opens the WebView page await $(find.text('Open Web Page')).tap(); // Allow the WebView to load by waiting and trying to settle for 15 seconds await $.pumpAndTrySettle(timeout: Duration(seconds: 15)); // Enter name into the first text input field (index 0) await $.native.enterTextByIndex( 'John Smith', index: 0, // Adjust index based on your specific form structure keyboardBehavior: KeyboardBehavior.alternative, ); // Enter email into the second text input field (index 1) await $.native.enterTextByIndex( 'student@masteringqa.com', index: 1, // Adjust index based on your specific form structure keyboardBehavior: KeyboardBehavior.alternative, ); // Enter password into the third text input field (index 2) await $.native.enterTextByIndex( 'test1234', index: 2, // Adjust index based on your specific form structure keyboardBehavior: KeyboardBehavior.alternative, ); Patrol Interacting With WebViewsPatrol uses the enterTextByIndex function to simulate typing text into specific input fields in the WebView. The index parameter specifies the position of the field within the WebView. The KeyboardBehavior.alternative parameter allows you to manage how the keyboard behaves during interactions, this is very crucial when working with IOS devices.Best Practices for Advanced and Native Interactions Use Assertions Wisely: Always validate expected outcomes after performing interactions. For instance, after a swipe action, assert that the correct screen is displayed or that the expected element is visible. Maintain Readable Code: Write clear and maintainable test scripts. Using descriptive names for actions and elements helps other team members understand your tests. Leverage Wait Commands: Utilize wait commands effectively to ensure that your tests are resilient to timing issues. Implementing proper waits between actions minimizes false negatives. Combine Interactions: Test complex user scenarios by combining multiple interactions. For example, you might simulate a user logging in, then navigating to a profile page and updating details.ConclusionMastering advanced and native interactions in Patrol Testing is essential for delivering high-quality mobile applications. By utilizing Patrol’s capabilities to simulate user behaviors and engage with native features, you can ensure a seamless user experience. Adopting the best practices in this guide will help you create effective and maintainable tests for comprehensive application validation.

Automating Gesture Actions in Appium In the previous guide, we learned about Appium UI Locator Strategies. Now, let’s take it a step further by automating gesture actions. Gestures such as swipes, scrolls, and taps are essential for comprehensive mobile app testing.Common Gesture ActionsAlright, let’s dive into Gesture Actions in Appium. These actions are essential for simulating complex interactions with your mobile app, mimicking how a real user would engage with it. Whether you need to swipe, pinch, zoom, or perform a drag-and-drop action, Appium’s gesture commands have you covered. These gestures are critical for testing user interfaces that rely heavily on touch interactions, ensuring your app behaves as expected in the hands of actual users.Create Gestures Util ClassLet’s dive right in and enhance our Appium project by adding a new class to handle gesture methods efficiently. To begin, we’ll create a new class called GesturesUtil which will serve as a repository for various gesture methods. This step is essential to keep our code organized and maintainable. First, navigate to your project directory and create a new package namedcom.helpers. This package will be the home for our GesturesUtilclass. Organizing your code into packages not only improves readability but also aligns with best practices in software development, making your project more modular and easier to manage.Import DependenciesIn the com.helpers package, create the GesturesUtil class. This class will encapsulate all the gesture methods you need for your Appium tests, such as swipe, tap, and scroll. To get started, the first step is importing the necessary dependencies. In your project, add the following imports:GesturesUtil.classimport io.appium.java_client.AppiumDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.interactions.PointerInput; import org.openqa.selenium.interactions.Sequence; import java.time.Duration; import java.util.Arrays; import java.util.Collections;With these imports in place, you can now proceed to define your gesture methods without encountering any compilation issues. This setup ensures that your code is well-structured and ready to handle a variety of automated testing scenarios, making your Appium testing framework robust and efficient.Simulating Tap or Long Press A tap is simply a quick touch on the screen, often used for selecting items, while a long press involves holding down on an element for a longer duration. This is typically used for actions like bringing up a context menu or initiating a special function. Appium’s capabilities allow you to simulate both, ensuring that these interactions are tested thoroughly.Gesture: tapElementpublic void tapElement(WebElement element) { PointerInput finger = new PointerInput(PointerInput.Kind.TOUCH, "finger"); Sequence tap = new Sequence(finger, 1) .addAction(finger.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), element.getLocation().x + element.getSize().width / 2, element.getLocation().y + element.getSize().height / 2)) .addAction(finger.createPointerDown(PointerInput.MouseButton.LEFT.asArg())) .addAction(finger.createPointerUp(PointerInput.MouseButton.LEFT.asArg())); driver.perform(Collections.singletonList(tap)); }TapThe tapElement method simulates a tap on a web element by: Creating a touch input named finger. Creating a sequence of actions that: - Moves the touch pointer to the center of the specified element. - Presses down on the element. - Releases the press. Perform the sequence of actions using the driver.Gesture: Long Presspublic void longPressElement(WebElement element, Duration duration) { PointerInput finger = new PointerInput(PointerInput.Kind.TOUCH, "finger"); Sequence longPress = new Sequence(finger, 1) .addAction(finger.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), element.getLocation().x + element.getSize().width / 2, element.getLocation().y + element.getSize().height / 2)) .addAction(finger.createPointerDown(PointerInput.MouseButton.LEFT.asArg())) .addAction(finger.createPointerMove(duration, PointerInput.Origin.viewport(), element.getLocation().x,element.getLocation().y)) .addAction(finger.createPointerUp(PointerInput.MouseButton.LEFT.asArg())); driver.perform(Collections.singletonList(longPress)); }Long PressThe longPressElement method simulates a long press on a mobile or web element by: Moving the virtual finger to the center of the element. Pressing down on the element. Holding the press for a specified duration. Releasing the press.Simulating Swipe GesturesIn Appium, swiping is straightforward but powerful, allowing you to simulate the user’s finger moving across the screen.To implement a swipe, you define the start and end coordinates, which tells Appium where the swipe should begin and end. By fine-tuning these coordinates, you can create swipes that mimic natural user behavior, ensuring your test cases are as realistic as possible.Gesture: Swipepublic void swipe(int startX, int startY, int endX, int endY, Duration duration) { PointerInput finger = new PointerInput(PointerInput.Kind.TOUCH, "finger"); Sequence swipe = new Sequence(finger, 1) .addAction(finger.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), startX, startY)) .addAction(finger.createPointerDown(PointerInput.MouseButton.LEFT.asArg())) .addAction(finger.createPointerMove(duration, PointerInput.Origin.viewport(), endX, endY)) .addAction(finger.createPointerUp(PointerInput.MouseButton.LEFT.asArg())); driver.perform(Collections.singletonList(swipe)); }SwipeThe swipe function simulates a swipe gesture on a touch screen. First, it moves the touch pointer from a starting point (startX, startY) Next it moves to the ending point (endX, endY) over a given duration. The process involves moving the pointer to the start position, touching down, moving to the end position, and then lifting up All of these actions are coordinated through a sequence of actions performed by the driver.Simulating a Zoom InNext we have pinch and zoom gestures, which are indispensable for applications that involve maps, images, or any form of visual content that users might need to zoom in and out of.Gesture: Zoom Inpublic void zoomIn(WebElement element) { int centerX = element.getLocation().getX() + element.getSize().getWidth() / 2; int centerY = element.getLocation().getY() + element.getSize().getHeight() / 2; int endX1 = centerX - 100; int endY1 = centerY - 100; int endX2 = centerX + 100; int endY2 = centerY + 100; PointerInput finger1 = new PointerInput(PointerInput.Kind.TOUCH, "finger1"); Sequence pinch1 = new Sequence(finger1, 1) .addAction(finger1.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), centerX, centerY)) .addAction(finger1.createPointerDown(PointerInput.MouseButton.LEFT.asArg())) .addAction(finger1.createPointerMove(Duration.ofMillis(600), PointerInput.Origin.viewport(), endX1, endY1)) .addAction(finger1.createPointerUp(PointerInput.MouseButton.LEFT.asArg())); PointerInput finger2 = new PointerInput(PointerInput.Kind.TOUCH, "finger2"); Sequence pinch2 = new Sequence(finger2, 1) .addAction(finger2.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), centerX, centerY)) .addAction(finger2.createPointerDown(PointerInput.MouseButton.LEFT.asArg())) .addAction(finger2.createPointerMove(Duration.ofMillis(600), PointerInput.Origin.viewport(), endX2, endY2)) .addAction(finger2.createPointerUp(PointerInput.MouseButton.LEFT.asArg())); driver.perform(Arrays.asList(pinch1, pinch2)); }PinchingPinching involves bringing two fingers together on the screen, while zooming involves spreading them apart. Appium handles these multi-touch gestures by specifying the touch points and their movements, giving you precise control over the interactions. Calculate the center coordinates (centerX, centerY)of the element. Define end coordinates for the pinch gesture (endX1, endY1, endX2, endY2). Create the first finger input sequence pinch1to: - Move to the center of the element. - Press down. - Move to the end coordinates over 600 ms. - Lift up the finger. Create the seond finger input sequence pinch2 to: - Move to the center of the element. - Press down. - Move to the end coordinates over 600 ms. - Lift up the finger. Execute both sequences simultaneously to perform the pinch gesture.Simulating a Zoom OutPerform a zoom out gesture by reversing the pinch gesture:Gesture: Zoom Outpublic void zoomOut(WebElement element) { int centerX = element.getLocation().getX() + element.getSize().getWidth() / 2; int centerY = element.getLocation().getY() + element.getSize().getHeight() / 2; int startX1 = centerX - 100; int startY1 = centerY - 100; int startX2 = centerX + 100; int startY2 = centerY + 100; PointerInput finger1 = new PointerInput(PointerInput.Kind.TOUCH, "finger1"); Sequence pinchIn1 = new Sequence(finger1, 1) .addAction(finger1.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), startX1, startY1)) .addAction(finger1.createPointerDown(PointerInput.MouseButton.LEFT.asArg())) .addAction(finger1.createPointerMove(Duration.ofMillis(600), PointerInput.Origin.viewport(), centerX, centerY)) .addAction(finger1.createPointerUp(PointerInput.MouseButton.LEFT.asArg())); PointerInput finger2 = new PointerInput(PointerInput.Kind.TOUCH, "finger2"); Sequence pinchIn2 = new Sequence(finger2, 1) .addAction(finger2.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), startX2, startY2)) .addAction(finger2.createPointerDown(PointerInput.MouseButton.LEFT.asArg())) .addAction(finger2.createPointerMove(Duration.ofMillis(600), PointerInput.Origin.viewport(), centerX, centerY)) .addAction(finger2.createPointerUp(PointerInput.MouseButton.LEFT.asArg())); driver.perform(Arrays.asList(pinchIn1, pinchIn2)); }ZoomingPinching involves bringing two fingers together on the screen, while zooming involves spreading them apart. Appium handles these multi-touch gestures by specifying the touch points and their movements, giving you precise control over the interactions. Calculate the center coordinates of the element. Define starting points for two touch actions, positioned diagonally around the center. Create a touch action sequence for the first finger, moving from the starting point to the center. Create a touch action sequence for the second finger, moving from the starting point to the center. Execute both sequences simultaneously to perform the pinch-in gesture.ConclusionIncorporating gesture actions into your Appium tests enhances functionality and verifies a seamless user experience. By simulating real user gestures, you can uncover issues that traditional testing may miss, leading to a more robust and user-friendly app.Whether you’re testing a simple or complex app, mastering these gestures will improve your testing outcomes. In the next guide, you’ll learn about Capturing Screenshots and Logs in Appium.

Capturing Screenshots and Logs In Appium Capturing screenshots and logs during your tests is crucial for diagnosing issues, verifying UI elements, and ensuring your app behaves as expected. Screenshots provide visual evidence, while logs offer detailed information about the app’s behavior, network requests, errors, and more.Create New Utils ClassLet’s begin by creating a new Utils class, which will be instrumental in managing your screenshot captures and logging methods. To start, navigate to your project and create a new class within the com.helpers package, or alternatively, any directory that suits your organizational preferences. Creating A New Utils ClassUtils.classpackage com.helpers; import org.openqa.selenium.OutputType; import org.openqa.selenium.TakesScreenshot; import org.openqa.selenium.WebDriver; import org.openqa.selenium.logging.LogEntry; import org.openqa.selenium.io.FileHandler; import org.openqa.selenium.logging.LogEntries; import org.openqa.selenium.logging.LogType;Capturing ScreenshotsTo capture screenshots in Appium using Java, you can use the getScreenshotAs method. Utils.classpublic class Utils { public static void captureScreenshot(WebDriver driver, String fileName) { File srcFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE); try { FileHandler.copy(srcFile, new File("./target/screenshots/" + fileName + ".png")); } catch (IOException e) { e.printStackTrace(); } } It’s important to organize your project structure effectively. To achieve this, we’ll create a dedicated /screenshots directory within the target folder of your project. This organization ensures that all screenshots are stored in a centralized location, making them easy to locate and manage. Creating A New Screenshots Directory For instance, when you capture a screenshot during the automation process, you can save it in this newly created directory. To maintain clarity and avoid confusion, it's essential to give each screenshot file a descriptive name. In this particular example, we will name the screenshot file add_new_task_screen.In this particular example, we will name the screenshot file add_new_task_screen. This naming convention not only helps in identifying the context of the screenshot quickly but also enhances the overall readability and maintainability of your test reports.Call this method in your test script where you want to capture the screenshot: Test: clickingAddTaskButton()@Test public void clickingAddTaskButton() throws InterruptedException { // Add test case scenario here WebElement addTaskButton = driver.findElement(By.id("com.example.todoapp:id/fab")); addTaskButton.click(); // quick debug wait for 2 seconds Thread.sleep(2000); WebElement addTaskTitle = driver.findElement(By.id("com.example.todoapp:id/titleEditText")); Assert.assertTrue(addTaskTitle.isDisplayed(), "User is on the Add Task Details Screen"); Utils.captureScreenshot(driver, "add_new_task_screen"); driver.navigate().back(); Thread.sleep(1000); }When executing your script in Appium, the captured screenshot is stored in the /target/screenshot/ directory. To view the newly captured screenshot, you will need to refresh your project. Once refreshed, the file named add_new_task_screen will appear in the screenshots directory. This step is crucial for verifying that your automation scripts are correctly capturing the visual output you expect. GIF: Reviewing Screenshot Image After Executing TestCapturing LogsTo capture logs in Appium using Java, you can use the getLog method. Here’s how:Test: captureLogs()public static void captureLogs(WebDriver driver) { LogEntries logEntries = driver.manage().logs().get(LogType.BROWSER); for (LogEntry entry : logEntries) { System.out.println(entry.getMessage()); } }Call this method in your test script to capture and print the logs: JavaUtils.captureLogs(driver);Troubleshooting Permission Issues: Ensure your script has write permissions to the directory where screenshots and logs are saved. Driver Compatibility: Make sure the Appium driver versions are compatible with your testing framework and mobile OS. Error Handling: Implement error handling in your scripts to manage exceptions during screenshot or log capture.Best Practices Organize Screenshots: Save screenshots with meaningful names and organize them in folders based on test cases or test runs. Log Levels: Use different log levels (e.g. INFO, DEBUG, ERROR) to filter logs effectively. Automate Log Analysis: Consider automating log analysis to highlight errors or warnings. Periodic Captures: Capture screenshots and logs periodically during long test runs to monitor app behavior over time.ConclusionBy now, you should know how to capture screenshots and logs during your Appium test executions. This knowledge will significantly enhance your ability to debug and report on your tests. Continue honing your skills and exploring more advanced topics in Appium and QA testing. Happy testing!
Introduction to Cucumber and Gherkin Welcome to Mastering QA! In this guide, we’ll introduce you to Cucumber and Gherkin, two powerful tools that revolutionize Behavior-Driven Development (BDD). Understanding these tools will provide a strong foundation for writing and automating your tests effectively.What is Cucumber?Cucumber is an open-source BDD framework that simplifies the process of defining and executing tests. It encourages collaboration between technical and non-technical team members, fostering better communication and understanding of software requirements.What is Gherkin?Gherkin is a human-readable language used to write Cucumber scenarios. It’s designed to be simple, easy to understand, and accessible to non-developers. Gherkin acts as the bridge between plain text descriptions of software behaviors and the automation code that validates those behaviors.Feature FilesFeature files are where Gherkin shines. These text files have a .feature extension and contain high-level descriptions of software features or functionalities. They serve as documentation and test scripts simultaneously.ScenariosScenarios are individual test cases written in Gherkin. They describe a specific behavior or test case, typically following a Given-When-Then structure. For example:Scenario: home-screen.featureFeature: Home Screen - Verify Web App Navigation Menu Links Scenario: Click the Login Icon Given the user is on the home screen When the user clicks the "login" icon Then the "Login" screen is displayed 1 Given 2 When 3 Then This keyword sets the stage for the scenario by describing the initial context or preconditions. It establishes the state of the system before the action occurs.This keyword defines the action or event that triggers the scenario. It represents the user's interaction with the system or the event that takes place.This keyword outlines the expected outcome or result after the action is performed. It specifies what should happen as a result of the interaction, allowing for validation of the scenario. Step DefinitionsStep definitions are the automation code that executes the steps in Gherkin scenarios.Step Defintionspublic class HomeStepDefs { public WebDriver driver = Hooks.driver; @Given("the user is on the home screen") public void the_user_is_on_the_home_screen() throws InterruptedException { // logic goes here } @When("the user clicks the {string} icon") public void the_user_clicks_the_icon(String iconName) { // logic goes here } @Then("the {string} screen is displayed") public void the_screen_is_displayed(String screenName) { // logic goes here } @When("the user clicks the {string} link") public void the_user_clicks_the_link(String linkName) { // logic goes here } }Benefits of Cucumber and Gherkin Improved Collaboration: Cucumber and Gherkin facilitate effective communication between technical and non-technical team members, leading to better software understanding. Reusable Steps: Gherkin steps can be reused across multiple scenarios, reducing redundancy and maintenance efforts. Living Documentation: Feature files serve as living documentation that stays up-to-date with your application's behavior. Automation: Cucumber allows you to automate tests based on Gherkin scenarios, making it easier to validate software functionality.ConclusionNow that you have a basic understanding of Cucumber and Gherkin, it’s time to Set Up Cucumber in Your Project.

Running the Test: To run the test, you can use an IDE like IntelliJ or Eclipse that supports TestNG, or you can run it from the command line.Conclusion You have successfully written and run your first TestNG test case. Next, we will explore the various annotations provided by TestNG that help in organizing and managing your test cases effectively. Stay tuned to learn about TestNG annotations in the upcoming guide. Understanding TestNG AnnotationsPreviously, we learned how to write and execute a simple test case using TestNG. This guide will focus on understanding TestNG annotations, which are crucial for structuring and managing your tests.TestNG Annotations: TestNG provides a rich set of annotations to control the execution flow of your tests. Here are some of the most commonly used annotations:@Test: Marks a method as a test method.@BeforeSuite: The method annotated with this will run before all tests in the suite.@AfterSuite: The method annotated with this will run after all tests in the suite.@BeforeClass: The method annotated with this will run before the first test method in the current class is invoked.@AfterClass: The method annotated with this will run after all the test methods in the current class have been run.@BeforeMethod: The method annotated with this will run before each test method.@AfterMethod: The method annotated with this will run after each test method.Example: import org.testng.annotations.*; public class AnnotationTest { @BeforeClass public void setUp() { System.out.println("This runs before any test method in the class"); } @Test public void testMethod1() { System.out.println("This is test method 1"); } @Test public void testMethod2() { System.out.println("This is test method 2"); } @AfterClass public void tearDown() { System.out.println("This runs after all test methods in the class"); } } ConclusionUnderstanding and using TestNG annotations will help you manage your test cases efficiently. In the next guide, we will discuss how to group test cases in TestNG to further enhance test organization. Continue reading to learn about grouping test cases in TestNG. Grouping Test Cases in TestNGIn the last guide, we explored TestNG annotations. Now, let’s look at how to group test cases in TestNG, a feature that allows you to categorize your tests and run them selectively.Grouping Test Cases: Grouping is useful when you want to categorize your tests, such as grouping all login-related tests together. You can define groups using the groups attribute in the @Test annotation.Example: import org.testng.annotations.Test; public class GroupingTest { @Test(groups = {"smoke"}) public void test1() { System.out.println("This is a smoke test"); } @Test(groups = {"regression"}) public void test2() { System.out.println("This is a regression test"); } @Test(groups = {"smoke", "regression"}) public void test3() { System.out.println("This is both smoke and regression test"); } } Running Grouped Tests: You can specify which groups to run in the TestNG XML configuration file. ConclusionGrouping test cases makes it easier to manage and execute related tests. In the next guide, we will delve into data-driven testing with TestNG, a powerful feature for running tests with multiple sets of data. Keep reading to understand how to implement data-driven testing in TestNG. Implementing Data-Driven Testing with TestNGPreviously, we discussed how to group test cases in TestNG. This guide will focus on implementing data-driven testing in TestNG, which allows you to run tests with various data sets, enhancing test coverage and reliability.Data Providers in TestNG: TestNG provides the @DataProvider annotation to facilitate data-driven testing. A data provider method returns an array of objects and can be used to pass multiple data sets to a test method.Example: import org.testng.annotations.DataProvider; import org.testng.annotations.Test; public class DataDrivenTest { @DataProvider(name = "loginData") public Object[][] dataProviderMethod() { return new Object[][] { {"user1", "pass1"}, {"user2", "pass2"} }; } @Test(dataProvider = "loginData") public void loginTest(String username, String password) { System.out.println("Username: " + username + ", Password: " + password); // Add your test logic here } } Using External Data Sources:Data providers can also fetch data from external sources like Excel files, databases, etc., making your tests even more flexible and robust.ConclusionData-driven testing in TestNG is a powerful feature that allows you to test multiple scenarios efficiently. In the next guide, we will explore parallel test execution in TestNG to optimize your test execution time. Continue reading to learn about running tests in parallel with TestNG. Parallel Test Execution in TestNGIn the last guide, we covered data-driven testing in TestNG. Now, let’s focus on parallel test execution, a feature that significantly reduces test execution time by running multiple tests simultaneously.Enabling Parallel Execution: You can enable parallel execution in TestNG by configuring your test suite in the XML file. You can run tests in parallel at the suite, test, or method level.Example: Parallel Test Class Example: import org.testng.annotations.Test; public class ParallelTest { @Test public void testMethod1() { System.out.println("Test Method 1, Thread: " + Thread.currentThread().getId()); } @Test public void testMethod2() { System.out.println("Test Method 2, Thread: " + Thread.currentThread().getId()); } } AdvantagesTime Efficiency: Run multiple tests simultaneously to save time.Resource Utilization: Utilize CPU resources more efficiently.Conclusion Parallel test execution in TestNG helps optimize your testing process by reducing the overall execution time. In the next guide, we will discuss using assertions in TestNG to validate your test results effectively. Continue reading to learn about assertions in TestNG. Using Assertions in TestNG to Validate TestIn the previous guide, we discussed parallel test execution in TestNG. Now, let’s focus on using assertions in TestNG, which are essential for validating test results and ensuring your tests behave as expected.Assertions in TestNG: TestNG provides a set of assertion methods to validate test outcomes. Commonly used assertions include assertEquals, assertTrue, assertFalse, assertNotNull, etc.Example: import org.testng.annotations.Test; import static org.testng.Assert.*; public class AssertionTest { @Test public void testEquality() { String actual = "TestNG"; String expected = "TestNG"; assertEquals(actual, expected, "Values are not equal"); } @Test public void testCondition() { boolean condition = true; assertTrue(condition, "Condition is false"); } } Custom MessagesAssertions can include custom messages to provide more context when a test fails, making it easier to diagnose issues.Conclusion Using assertions in TestNG is crucial for verifying that your tests produce the expected results. This concludes our series on TestNG guides. By now, you should have a solid understanding of how to use TestNG for various testing scenarios. Continue exploring and mastering TestNG to enhance your testing capabilities.

To get started, we’ll need to create a few specific folders. In this guide we’ll be incorporating the com.kicksapp package in our project to keep our files organize. Organizing Cucumber Project com/kicksapp/runners - This folder is where our test runner files will be stored. These files are essential for executing our test suites. com/kicksapp/stepdefs - Here, we'll keep our test step definitions. This organization helps in managing the steps involved in our tests, making them easy to locate and modify. src/test/resources/driver - This is the designated folder for our driver files. For this project, we'll be using Chromedriver. Ensuring the driver is in the right place helps in seamless test execution. src/test/resources/features - Most importantly, this folder will store our feature files. Feature files are the cornerstone of our behavior-driven development (BDD) approach, outlining the scenarios and behaviors our application should exhibit. Tip: Naming Your Package DirectoryYou can choose to keep you package as simple as src/test/java/runners or src/test/java/stepdefs. However in this guide We’ll be using the com/kicksapp/… package.Downloading the Cucumber Plugin for EclipseOnce we have these packages and folders set up, the next step is to download the Cucumber plugin for Eclipse.

This setup not only enhances productivity but also aligns with best practices in test automation, making it easier to scale and maintain your tests.Now you’re ready to Write Your First Gherkin Feature File. Continue to the next guide to dive into writing Gherkin scenarios.
Writing Your First Gherkin Feature File Now that you have Cucumber set up in your project, it’s time to write your first Gherkin feature file. This guide will help you create a feature file and define scenarios using Gherkin syntax.Gherkin feature files are written with the .feature extension and contain a structured language with keywords like Feature, Scenario, Given, When, Then, And, and But. Let’s write a simple feature file for a checking the navigation on the Kicks Web App functionality. Kicks App | Flutter WebCreating a Feature FileFirst, navigate to your project’sfeaturesdirectory. This is where all your feature files will reside. To get started with our scenarios, we need to create a new file. Create a file named home-screen.feature inside the features directory. Creating The Home Screen Feature FilePath: home-screen.featuresrc/test/resources/features/home-screen.featureBy creating the home-screen.feature file, we establish a dedicated space for our home screen scenarios. This approach not only helps in organizing our tests but also makes it easier to locate and update them as needed.Write a Feature Scenario Ensuring a seamless user experience starts with verifying that all navigation links on the home screen function as expected. Below we are going test a few test cases related to the navigation menu.home-screen.feature# Author: J Richard | Mastering QA Feature: Home Screen - Verify Web App Navigation Menu Links Scenario: Click the Login Icon Given the user is on the home screen When the user clicks the "login" icon Then the "Login" screen is displayed Scenario: Click the Products link Given the user is on the home screen When the user clicks the "Products" link Then the "Products" screen is displayed Home Screen Feature File ScenariosUnderstanding Gherkin Syntax Feature: Provides a detailed overview of the feature being tested, outlining its purpose and functionality. Scenario: Specifies a particular test case for the feature, illustrating a unique situation to validate its performance. Given: Establishes the initial conditions and context necessary for the test to proceed, ensuring a proper setup. When: Captures the specific actions taken by the user during the test, detailing the interactions that trigger the functionality. Then: Articulates the expected results of the test, defining the criteria for success and the desired behavior of the feature. Given the user is on the home screenThis step sets the initial context. It assumes the user has already landed on the home screen of the web application. When the user clicks the "login" icon This action step simulates the user clicking on the login icon, which is expected to take them to the login screen. Then the "Login" screen is displayedThe final step verifies the outcome, ensuring that clicking the login icon indeed navigates the user to the login screen. Click the Products Link TestThe second scenario is pretty much similar but in this case we will be clicking the products link and verifying that we landed there successfully.ConclusionYou’ve written your first Gherkin feature file. Next, you’ll learn how about Scenario Outlines and Examples. Continue to the next guide to explore step definitions.

Scenario Outlines and Examples In this guide, you’ll learn how to use scenario outlines and examples to write more dynamic and data-driven tests. This allows you to test multiple cases with different inputs and expected outcomes efficiently.What is a Scenario Outline? A Scenario Outline is a template for a scenario that can be run multiple times with different sets of data. It is useful when you want to test the same scenario with different inputs and expected outcomes. This helps in reducing redundancy and improving the readability and maintainability of your test suite.Syntax of Scenario OutlineThe syntax of a Scenario Outline in Gherkin is as follows:GherkinScenario Outline: Title of the scenario Given some precondition When some action is performed Then some expected outcome should happen Examples: | parameter1 | parameter2 | | value1 | value2 | | value3 | value4 | Scenario Outline: This keyword establishes a scenario template that allows for the reuse of the same test steps with varying data inputs, streamlining the testing process. Examples: This section specifies the various sets of data that will be used to fill in the placeholders defined in the Scenario Outline, enabling comprehensive testing of multiple scenarios efficiently.Using Examples in Scenario Outline The Examples section contains a table where each row represents a different set of values to be used in the scenario. The values from the table are substituted into the scenario outline, and the scenario is run once for each row. Cucumber Scenario Outline ExampleConsider a scenario where we want to test the products filter functionality of the Kicks website with different filters and verifying the item counts. This involves simulating user actions on the website to ensure that the filters for products work as expected.GherkinFeature: Products Page Filters & Stock Count Scenario Outline: User clicks product filter, choose a gender option and verify item count Given the user is on the products screen When the user clicks "<filter>" filter option And the user clicks the "<gender>" gender option And the user clicks a "<size>" shoe Then the first sneaker option is "<first_sneaker>" And the result is now "<item_count>" Examples: | filter | gender | size | first_sneaker | item_count | | Most popular | Male | 10.5 | Adidas Converse | 7 items | | Lowest price | Female | 6 | New Balance Streetwear | 13 items | | Highest price | Male | 9.5 | Jordan Orginal | 9 items | | Newest | Female | 7 | Nike Air Max 360 | 14 items |This feature focuses on verifying that the product filters on the Kicks website are working correctly. It includes tests for various filters such as Most popular, Lowest price, Highest price, and Newest to ensure they return the correct item count. Given the user is on the products screenThis step sets the initial condition that the user is on the products page of the website. When the user clicks "<filter>" filter optionThis action simulates the user clicking on a specific filter option, such as Most popular or Lowest price. And the user clicks the "<gender>" gender optionThis action simulates the user selecting a gender filter, such as Male or Female. And the user clicks a "<size>" shoeThis action simulates the user selecting a shoe size, such as 10.5 or 6. Then the first sneaker option is "<first_sneaker>"This step verifies that the first sneaker displayed matches the expected sneaker for the given filter. And the result is now "<item_count>"This step verifies that the total number of items displayed matches the expected item count.ConclusionGherkin Scenario Outlines are essential for enhancing clarity and efficiency in your behavior-driven development (BDD) process. They allow for reusable scenarios with varying inputs, simplifying test case creation and promoting collaboration among team members. In the next guide, you’ll learn about Implementing Step Definitions, where we’ll connect your Gherkin scenarios to executable code.

Implementing Step Definitions Now is the time to create and implement our Step Definition Class in Cucumber. This critical step will ensure our test automation framework is robust and efficient. In this guide, we will walk you through the process of setting up your Step Definition Class, specifically focusing on creating a file to store your HomeStepDefs file within your project.Setting Up Your Step Definition ClassTo begin, navigate to the appropriate location in your project directory where you want to store your Step Definition files. It’s essential to keep your project well-organized, making it easier to maintain and scale as needed. In this case we’ll be storing our files in this location – src/test/java/com/kicksapp/stepDefs Cucumber Step Definitions Directory IDE: Launch Eclipse and open your project to get started on your Gherkin test definitions. Directory: Navigate to the src/test/java/com/kicksapp/stepDefs/ directory, where your step definitions will be organized. Create a New File: In the stepDefs directory, right-click and choose [direction]New File[/direction] to create a new file named HomeStepDefs.java, which will house your Gherkin step definitions for the Home feature.HomeStepDefssrc/test/java/kicksapp/stepDefs/HomeStepDefs.javaConvert Project to A Cucumber ProjectRight-click on your project and select Configure Convert to Cucumber Project . This set is necessary so we can generate our gherkin snippets. Converting Project To A Cucumber ProjectGenerate Gherkin Method SnippetsTo generate the necessary Gherkin method snippets, run the home-screen.feature file: Run Feature File: Right-click on the home-screen.feature file and select [direction] Run As > Cucumber Feature[/direction]. Review Snippets: Eclipse will execute the feature file, and if any step definitions are missing, it will generate method snippets for you. Copy these snippets into your HomeStepDefs.java class. Gherkin Generated Sample SnippetsGherkin Method Snippets@Given("the user is on the home screen") public void the_user_is_on_the_home_screen() { // Write code here that turns the phrase above into concrete actions throw new io.cucumber.java.PendingException(); } @When("the user clicks the {string} icon") public void the_user_clicks_the_icon(String string) { // Write code here that turns the phrase above into concrete actions throw new io.cucumber.java.PendingException(); } @Then("the {string} screen is displayed") public void the_screen_is_displayed(String string) { // Write code here that turns the phrase above into concrete actions throw new io.cucumber.java.PendingException(); } @When("the user clicks the {string} link") public void the_user_clicks_the_link(String string) { // Write code here that turns the phrase above into concrete actions throw new io.cucumber.java.PendingException(); }Now that we have our snippets, it’s time to add the necessary logic to each method to complete our HomeStepDefs class. This step is crucial as it bridges the gap between our feature files written in Gherkin and the actual automation code that interacts with our web application.In the HomeStepDefs class, we initialize a WebDriver instance through the Hooks class, ensuring a consistent browser session. The testUrl variable holds the URL of our web application, setting the stage for user interaction scenarios.HomeStepDefs – WebDriverpublic class HomeStepDefs { public WebDriver driver = Hooks.driver; private final String testUrl = "https://jahmalrichard.github.io/kicks-flutter-web-app/";Navigating to the Home ScreenThe first step is to navigate the user to the home screen. Using the @Given annotation, we define the method the_user_is_on_the_home_screen. This method directs the browser to the specified URL and pauses for 2 seconds to ensure the page is fully loaded. Kicks App | Home Screen@Given@Given("the user is on the home screen") public void the_user_is_on_the_home_screen() throws InterruptedException { driver.get(testUrl); Utils.wait(2); }Interacting with IconsNext, we manage user interactions with icons on the home screen. The @When annotation is used to define the method the_user_clicks_the_icon. This method receives an icon name as a parameter, locates the corresponding icon using a CSS selector, and performs a click action. Find & Click The Login Icon@When@When("the user clicks the {string} icon") public void the_user_clicks_the_icon(String iconName) { try { switch(iconName.toLowerCase()) { case "login": { WebElement loginIcon = driver.findElement( By.cssSelector("flt-semantics[aria-label=\"login-icon\"]")); loginIcon.click(); Utils.wait(2); break; } default: System.err.println("The icon called '" + iconName + "' was not found. Try again."); } } catch (Exception e) { e.printStackTrace(); } }Verifying Screen DisplaysAfter interacting with icons, it’s essential to verify that the correct screen is displayed. The @Then annotation defines the method the_screen_is_displayed, which checks for the presence of the Sign In button on the login screen to confirm successful navigation. Verify That The Sign In Button Exist Verifying That The Product Page Is Displayed@Then@Then("the {string} screen is displayed") public void the_screen_is_displayed(String screenName) { try { switch(screenName.toLowerCase()) { case "login": { WebElement loginSignInButton = driver.findElement(By.cssSelector("flt-semantics[aria-label=\"Sign In\"]")); assert loginSignInButton.isDisplayed(); Utils.wait(2); break; } case "products": { WebElement filterMostPopular = driver.findElement(By.cssSelector("flt-semantics[aria-label=\"Most popular\"]")); assert filterMostPopular.isDisplayed(); Utils.wait(2); break; } default: System.err.println("The screen named '" + screenName + "' was not found. Try again."); } } catch (Exception e) { e.printStackTrace(); } }Navigating via LinksLastly, we enable users to click on various links within the application. The @When annotation is used again to define the method the_user_clicks_the_link, which handles click actions for specified links. Tip: Navigating LinksThis method is related to the second scenario, where we click on the Products link and verify that we’re on he Products screen. User Clicks The Products Link@When@When("the user clicks the {string} link") public void the_user_clicks_the_link(String linkName) { try { switch(linkName.toLowerCase()) { case "products": { WebElement productsNavLink = driver.findElement( By.cssSelector("flt-semantics[aria-label=\"Products\"]")); productsNavLink.click(); Utils.wait(2); break; } default: System.err.println("The link named '" + linkName + "' was not found. Try again."); } } catch (Exception e) { e.printStackTrace(); } } } Tip: HomeStepDefsBy integrating these methods into our HomeStepDefs class, each method is crafted to handle specific interactions and verifications, making our tests both comprehensive and easy to understand.ConclusionNow that we have a solid grasp of creating and managing step definitions, it’s time to elevate our Cucumber skills further.

Understanding Cucumber Tags In this guide, you’ll learn how to use Cucumber tags and hooks to organize and manage your tests efficiently. Tags allow you to categorize your scenarios, and hooks provide a way to run code before or after scenarios.Tags in CucumberTags are a way to organize and control the execution of your tests. They allow you to group scenarios, features, or even specific steps, making it easier to manage large test suites. Tags are prefixed with @ and placed above the relevant Gherkin keyword. Single TagA single tag, such as @smoketest or @ignore, is used to label a specific test scenario. For instance, @smoketest indicates a basic test run to check the essential functionality, while @ignore is used to exclude certain tests from execution.Single Tag: @smoketest | @ignore@smoketest Scenario: Click the Login Icon Given the user is on the home screen When the user clicks the "login" icon Then the "Login" screen is displayed @ignore Scenario: Click the Products link Given the user is on the home screen When the user clicks the "Products" link Then the "Products" screen is displayedMultiple TagsMultiple tags, like @smoketest @critical, combine multiple categories, providing a more granular control over which tests to run. This combination might be used to run tests that are both part of the smoke test suite and critical for the application, ensuring that key functionalities are validated promptly.Multiple Tags: @smoketest @critical@smoketest @critical Scenario: Click the Login Icon Given the user is on the home screen When the user clicks the "login" icon Then the "Login" screen is displayedCreating a Test RunnerCreate a test runner class in the src/test/java/com/kicksapp/runners directory. We’re going to name this class HomeScreenRunner. Creating Home Screen Runner FileRunning Tests with TagsTo run tests with specific tags, use the @RunWithand @CucumberOptions annotations in your test runner class.The @CucumberOptions annotation is where you configure various aspects of your Cucumber tests. Here’s a breakdown of the options used in the snippet: Cucumber Runner File With OptionsHomeScreenRunner.classimport org.junit.runner.RunWith; import io.cucumber.junit.Cucumber; import io.cucumber.junit.CucumberOptions; @RunWith(Cucumber.class) @CucumberOptions( features = "src/test/resources/features/home-screen.feature", glue = "com.kicksapp.stepdefs", tags = "@smoketest", plugin = {"pretty", "html:target/cucumber-reports.html"}, monochrome = true ) public class HomeScreenRunner { }features = "src/test/resources/features/home-screen.feature": This specifies the path to the feature files. Feature files contain scenarios written in Gherkin language, which Cucumber executes.glue = "com.kicksapp.stepdefs": This option specifies the package where step definition methods are located. Step definitions are the actual code implementations of the steps described in the feature files.tags = "@smoketest": Tags are used to filter which tests to run. In this case, only the scenarios tagged with @smoketest will be executed.plugin = {"pretty", "html:target/cucumber-reports.html"}: This specifies the reporting plugins to use. The html plugin generates a simple html test report.monochrome = true: This option makes the console output more readable by removing unnecessary characters and colors.Tag ExpressionsCucumber supports tag expressions to combine multiple tags using logical operators: AND The AND operator in Cucumber tag expressions is used to run scenarios that are tagged with multiple tags simultaneously. For instance, consider the tags @login and @critical. By using the expression @login and @critical, Cucumber will execute only those scenarios that are tagged with both @login and @critical. This is particularly useful when you need to focus on tests that are both essential and pertain to specific functionalities.Tags: AND@CucumberOptions( features = "src/test/resources/features/home-screen.feature", glue = "com.kicksapp.stepdefs", tags = "@login and @critical", plugin = {"pretty", "html:target/cucumber-reports.html"}, monochrome = true ) OR The OR operator broadens the scope by running scenarios that match any of the specified tags. For example, using @moketest or @critical will run all scenarios tagged with either @smoketest or @critical. This approach is beneficial when you want to cover a broader range of tests without being too restrictive, ensuring that all relevant functionalities are tested.Tags: OR@CucumberOptions( features = "src/test/resources/features/home-screen.feature", glue = "com.kicksapp.stepdefs", tags = "@smoketest or @critcal", plugin = {"pretty", "html:target/cucumber-reports.html"}, monochrome = true ) NOT The NOT operator is employed to exclude specific tags from the test run. For example, the expression not @ignore will execute all scenarios except those tagged with @ignore. This is especially useful for excluding tests that are either known to fail, are under development, or are not currently relevant to the test cycle.Tags: NOT@CucumberOptions( features = "src/test/resources/features/home-screen.feature", glue = "com.kicksapp.stepdefs", tags = "@smoketest and not @ignore", plugin = {"pretty", "html:target/cucumber-reports.html"}, monochrome = true )ConclusionYou’ve mastered the art of using tags. Tags allow you to categorize your scenarios, making it easier to run specific tests based on your needs. Whether you’re focusing on a particular feature or running regression tests, tags streamline the process, saving you valuable time.Now that you are comfortable with tags, it’s time to start Understanding Cucumber Hooks.
Understanding Cucumber Hooks In this guide, you’ll learn how to use Cucumber hooks to streamline your testing process and make your scenarios more efficient. Cucumber hooks are blocks of code that run at various points in the Cucumber test cycle, allowing you to set up and tear down the test environment, manipulate data, and configure test settings dynamically. By mastering hooks, you can enhance your test suite’s maintainability and readability, ensuring that your tests run smoothly and reliably.Hooks in CucumberHooks are special blocks of code that run at specific points in the test execution lifecycle. They allow you to set up preconditions and postconditions for your tests. In Cucumber, hooks are defined using the @Before and @After annotations.Types of HooksBefore HookThe @Before hook, as the name suggests, runs before each scenario. This means that any code you include in a @Before hook will execute before your test case starts. This is essential for preparing the test environment, ensuring that each test runs in a clean and consistent state. For instance, you might want to launch a browser, navigate to a specific URL, or initialize test data.@Before Hookpublic class Hooks { public static WebDriver driver; @Before public void setup() { System.setProperty("webdriver.chrome.driver", "src/test/resources/driver/chromedriver"); driver = new ChromeDriver(); driver.manage().timeouts().implicitlyWait(Duration.ofSeconds(10)); driver.manage().window().maximize(); }After HookAmong the different types of hooks, the @After hook plays a crucial role in ensuring your test scenarios are executed smoothly and efficiently. Specifically, the @After hook runs after each scenario, providing a perfect opportunity to perform cleanup tasks, release resources, or log information that helps in debugging and analysis.@After Hook@After public void tearDown() { if (driver != null) { driver.quit(); driver = null; }BeforeStepThe @BeforeStep hook, as its name suggests, runs before each individual step in your test scenarios. This hook can be particularly useful for setting up preconditions or performing repetitive tasks that need to be executed before every step.@BeforeStep Hook@BeforeStep public void beforeStep(Scenario scenario) { System.out.println("About to execute step: " + scenario.getName()); }AfterStepThe @AfterStep hook in Cucumber is designed to run a block of code after every single step of your test scenario. This capability is essential for tasks such as taking screenshots after each step to help with debugging or logging detailed information about the execution of each step. Implementing the @AfterStep hook can significantly enhance the visibility and traceability of your tests, making it easier to identify where an issue occurred if a test fails.@AfterStep Hook@AfterStep public void afterStep(Scenario scenario) { Utils.wait(3); final byte[] screenshot = ((TakesScreenshot) driver).getScreenshotAs(OutputType.BYTES); scenario.attach(screenshot, "image/png", "image"); }Conditional Hooks To further refine and control the execution of hooks, Cucumber provides the feature of conditional hooks with tags. Tags in Cucumber are metadata assigned to scenarios or feature files, and they can be used to conditionally apply hooks. For instance, if you have specific setup or teardown procedures that should only run for certain tests, you can tag those tests accordingly and define hooks that only trigger for those tags.Conditional Tagsimport io.cucumber.java.Before; import io.cucumber.java.After; public class Hooks { @Before("@login") public void beforeLogin() { // Code to run before scenarios tagged with @login } @After("@logout") public void afterLogout() { // Code to run after scenarios tagged with @logout } }ConclusionIncorporating hooks into your Cucumber tests is a powerful way to maintain a stable test environment, enhancing the overall reliability of your test suite. With hooks, you gain precise control over your test execution process, ensuring each scenario begins and ends in a consistent state. This mastery can lead to more trustworthy and efficient testing, ultimately contributing to higher quality software. Now that you are comfortable with tags and hooks, it’s time to start Running Your Cucumber Tests & Generating Reports.

To install Cypress, simply run the command that adds it to your project dependencies, and NPM will take care of the rest.NPM: Installing Cypressnpm install cypress --save-dev Installing Cypress via NPMVerify InstallationAfter the installation process is complete, it’s important to verify that Cypress has been installed correctly. This can be done by opening Cypress through a command in your terminal. If everything has been set up properly, Cypress will launch, indicating that your installation was successful.NPM: Open Cypressnpx cypress open Cypress Installed SuccessfullyCypress StructureWhen you first open Cypress, it automatically generates a structured directory designed to streamline your testing workflow. This directory, simply named cypress, is home to several key folders that play a pivotal role in organizing your test suite.Cypress Project Structurecypress/ ├── fixtures/ ├── e2e/ ├── plugins/ └── support/ fixtures: This is where you store any static data that your tests might need. Whether it's sample JSON files or other data formats, this folder is your go-to place for predefined data sets that help simulate various test scenarios. e2e: This is where the actual test scripts reside, ready to be executed. By keeping your test scripts organized in this manner, Cypress ensures that you can easily manage and locate them as your testing suite grows. plugins:Cypress allows you to extend its functionality through various plugins, and this is the folder where those plugins live. By utilizing plugins, you can customize and enhance Cypress to better fit your project's specific needs. support: This folder is where you'll store custom commands and configurations. This is the backbone of your test suite’s functionality, allowing you to define reusable commands and tailor Cypress's behavior to match your testing requirements.Configure CypressCypress is configured using a file named cypress.json. This configuration file is crucial as it allows you to set various options to control Cypress’s behavior. For instance, you can specify the baseUrl for your tests, like so: cypress.json{ "baseUrl": "http://localhost:3000" }ConclusionWith Cypress installed and your directory structure in place, you’re now ready to dive deeper. The next step is Writing Your First Test In Cypress, which we will explore in the following guide. This will provide you with hands-on experience with Cypress, allowing you to harness its powerful features effectively and efficiently. This foundational understanding is crucial for anyone serious about mastering end-to-end testing with Cypress.
Writing Your First Test in Cypress With Cypress installed and set up, it’s time to write your first test. This guide will walk you through creating a basic test to validate that Cypress is correctly configured and running. Writing tests in Cypress is intuitive and straightforward. Here’s an example of a basic test:Writing a Cypress TestHere’s an example test that checks if the login page loads correctly when the icon is clicked from the Home screen.Create a New Test FileCreate a new file in the cypress/e2e/home directory. In this example we’re going to create a new test file called home.cy.js. This file is going to house all of our scenarios related the Home page. home.cy.jsdescribe('Home Screen', () => { it('should navigate to the login page when the login icon is clicked', () => { const kicksAppsUrl = 'https://jahmalrichard.github.io/kicks-flutter-web-app/'; cy.viewport(1920, 1080); // Set the viewport to a standard desktop size cy.visit(kicksAppsUrl); // Load the web application cy.get('flt-semantics[aria-label="login-icon"]') .should('be.visible').click(); // Locate and click the login icon cy.get('flt-semantics[aria-label="Sign In"]') .should('exist'); // Verify navigation to the login page }); });In this example, the describe block is used to group tests related to the Home Screen. Inside the it block, we have a single test case that checks whether the application correctly navigates to the login page when the login icon is clicked. Test Setup: The first step in the test is setting up the viewport size to 1920x1080 pixels. This ensures the test runs in a simulated screen size that closely mirrors a typical desktop display. This is optional. Visiting the Application URL: The next step involves visiting the specific URL of the web application. This is done using cy.visit(kicksAppsUrl);, where kicksAppsUrl is a variable holding our application's URL. Interacting the Login Icon: Once the page is loaded, the test uses cy.get to locate the login icon on the page. This element is identified using a semantic label aria-label="login-icon" within the flt-semantics tag. The should('be.visible') command ensures that the icon is visible before attempting to click it. This step is critical as it validates that the icon is correctly displayed on the page before any action is performed. Asserting the URL Path: The test asserts that the URL now contains the /sign-in path using cy.url().should('include', '/sign-in'). This check ensures that the application navigates to the correct page after the icon is clicked. Verifying Navigation to the Login Page: After clicking the login icon, the test checks whether the application has navigated to the login page by looking for an element with the aria-label="Sign In". The should('exist') command is used here to confirm that this element is present in the DOM, which indicates successful navigation. Run Your TestOpen Cypress Test Runner if it’s not already openRun Testnpx cypress open Browsers Available To Run Test OnSelect your test file home.cy.js from the Test Runner to execute it. You should see your test running in the browser, with all assertions passing. Cypress Runner with Home Spec Cypress Run Home Test - PassedConclusionYou’ve written and executed your first Cypress test. This basic test demonstrates how to visit a page, interact with elements, and make assertions. In the next guide, we will delve into Setting Up A Reliable & Scalable Tests to better understand how to organize and manage your test suite effectively.
Setting Up a Reliable and Scalable Test Suite In Cypress In this guide I’ll walk you through some essential Cypress features, such as setting the baseUrl, using the beforeEach hook, organizing tests with nested describe blocks, and creating custom commands. Let’s dive in!Using the baseUrl to Store Your Test URLOne of the first steps in setting up a Cypress project is configuring your test environment. Instead of hardcoding URLs throughout your tests, you can streamline your code by using the baseUrl configuration in Cypress. This not only makes your tests more maintainable but also easier to read and manage. Setting the baseUrl: To set up your baseUrl, navigate to your cypress.json file (located in the root of your Cypress project) and add the following configuration:cypress.config.jsconst { defineConfig } = require("cypress"); module.exports = defineConfig({ e2e: { defaultCommandTimeout: 10000, // 10 seconds pageLoadTimeout: 60000, // 60 seconds for page load baseUrl: 'https://jahmalrichard.github.io/kicks-flutter-web-app/', setupNodeEvents(on, config) { }, }, }); With this configuration, you can now visit your URL automatically during test.cy.visitcy.visit('/');Cypress automatically prepends the baseUrl to any relative URL you provide, making your tests more readable and easier to maintain. If you ever change your testing environment (e.g., from localhost to a staging server), you only need to update the baseUrl in one place.Using the beforeEach Hook in CypressThe beforeEach hook is a powerful feature in Cypress that allows you to run a specific piece of code before each test within a describe block. This is particularly useful for setting up a consistent test environment, ensuring that each test starts with the same conditions. Implementing beforeEach: In our sample script, we see the beforeEach hook used to set the viewport size and visit the homepage before each test. cy.viewport(1500, 780): Sets the browser window size to 1500x780 pixels, ensuring consistency across all tests. cy.visit('/'): Navigates to the homepage, using the relative path since baseUrl is set. cy.wait(5000):Pauses the test for 5 seconds to ensure that all elements on the page are loaded and ready for interaction.beforeEachdescribe('Home Screen', () => { beforeEach(() => { // This will run before each test, ensuring the website is always launched with custom viewport cy.viewport(1500, 780); cy.visit('/'); cy.wait(5000); // Ensures the page has fully loaded before running the test }); // Test cases will follow here... });This setup ensures that every test in the Home Screen block starts with the same conditions, leading to more reliable and predictable test outcomes.Using Nested describe BlocksAs your test suite grows, organizing your tests becomes crucial. Cypress allows you to structure your tests using nested describe blocks, which is particularly useful for grouping related tests and making your test suite easier to navigate.Implementing Nested describe Blocks:In the provided script, we see a nested describe structure used to organize tests related to the Home Screen and its Navigation Menu: Outer describe block (Home Screen): Groups all tests related to the home screen of your application. Nested describe block (Navigation Menu): Further organizes tests that specifically deal with the navigation menu.Nested describe()describe('Home Screen', () => { beforeEach(() => { cy.viewport(1500, 780); cy.visit('/'); cy.wait(5000); }); describe('Navigation Menu', () => { it('should navigate to the About Us page when the about link is clicked', () => { cy.get('flt-semantics[aria-label="About us"]') .should('be.visible') .focus() .click({ force: true }); cy.url().should('include', '/about-us'); const aboutUsPageHTitle = createMultilineSelector('About us'); cy.get(aboutUsPageHTitle).should('be.visible'); }); // Additional test cases for other navigation links... }); });This structure not only makes your tests easier to manage but also provides clear reporting when tests are run. You can easily identify which part of your application a failing test belongs to based on the describe block hierarchy.Using Custom Commands in CypressCypress allows you to extend its functionality by creating custom commands, which can simplify repetitive tasks and make your tests more expressive. Custom commands are particularly useful for abstracting complex interactions or frequently used selectors.Creating and Using a Custom Command:In the provided script, the createMultilineSelector command is imported and used to generate a selector for elements with multiline text. createMultilineSelector: This custom command likely returns a selector that matches elements based on their aria-label attribute, specifically targeting multiline text. By using this command, we avoid duplicating complex selectors throughout our tests. Usage in Tests:Instead of writing out the full selector each time, you simply call createMultilineSelector('About us'), making the test more readable and easier to maintain.Using createMultilineSelectorimport { createMultilineSelector } from '../../support/e2e.js'; describe('Home Screen', () => { beforeEach(() => { cy.viewport(1500, 780); cy.visit('/'); cy.wait(5000); }); describe('Navigation Menu', () => { it('should navigate to the About Us page when the about link is clicked', () => { cy.get('flt-semantics[aria-label="About us"]') .should('be.visible') .focus() .click({ force: true }); cy.url().should('include', '/about-us'); const aboutUsPageHTitle = createMultilineSelector('About us'); cy.get(aboutUsPageHTitle).should('be.visible'); }); // Additional test cases... }); });Creating Custom CommandsYou can define custom commands in the cypress/support/e2e.js file. Here’s how you might define the createMultilineSelector command:Custom function – createMultilineSelector()import './commands' export function createMultilineSelector(text) { let selector = 'flt-semantics[aria-label="'; for (let i = 0; i < text.length; i++) { selector += text[i]; if (i < text.length - 1) { selector += '\n'; // Add a newline after each character, except the last one } } selector += '"]'; return selector; }This function dynamically creates a selector that matches any element whose aria-label contains the specified text, making it versatile for various testing scenarios. ConclusionNow that we have our Cypress script set up in a scalable state, we’re ready to take the next step Running Test Scenarios in Cypress to ensure our application behaves as expected across different user interactions. This is where the true power of Cypress shines. By crafting various test scenarios, we can simulate real-world usage patterns, validating that all parts of our web application function correctly under different conditions.
Running Test Scenarios in Cypress Before diving into the methods of running tests, let’s first expand our test suite with a few additional scenarios. These new tests will help us better understand the different ways Cypress can be utilized.Enhancing the Home Screen ScenariosIn this guide we’ll be going through the application, checking the links in the header menu like Products, Login, Cart. These are essential user flows, and ensuring they work correctly is vital for a seamless user experience. For instance, when the user clicks on the Products link, the application should navigate to the Products page, where the title Performance Sneakers should be visible. Similarly, clicking the login icon should direct the user to the sign-in page, with the Sign In button present and ready for interaction. The same applies to the Cart icon, leading the user to a Shopping Cart page, confirming the presence of the Shopping Cart title.Below is the enhanced version of the previous home screen test file, which includes test the new use cases mentioned above.Enhanced Home Screen Scenariosit('should navigate to the Products page when the products link is clicked', () => { cy.get('flt-semantics[aria-label="Products"]') .should('be.visible') .focus() .click({ force: true }); cy.url().should('include', '/products'); cy.wait(3000); const productsPageTitle = createMultilineSelector('Performance Sneakers'); cy.get(productsPageTitle).should('be.visible'); }); it('should navigate to the Login page when the login icon is clicked', () => { cy.get('flt-semantics[aria-label="login-icon"]') .should('be.visible') .focus() .click({ force: true }); cy.url().should('include', '/sign-in'); cy.get('flt-semantics[aria-label="Sign In"]').should('exist'); }); it('should navigate to the Cart page when the cart icon is clicked', () => { cy.get('flt-semantics[aria-label="cart-icon"]') .should('be.visible') .focus() .click({ force: true }); cy.url().should('include', '/cart'); const shoppingCartTitle = createMultilineSelector('Shopping Cart'); cy.get(shoppingCartTitle).should('be.visible'); });Running Test Using: Cypress RunNow that we’ve expanded our test suite, we can explore different ways to run these tests in Cypress. One approach is using the Cypress run command. This command allows you to run your tests in headless mode, meaning the tests execute without opening a browser window. This method is particularly useful for integrating tests into CI/CD pipelines where you need the tests to run automatically without manual intervention.cypress runnpx cypress run --spec cypress/e2e/home/home-advance.cy.js Cypress Testing Running In Headless ModeRunning Test Using: Cypress OpenAlternatively, you can use the npx cypress open command. This command opens the Cypress Test Runner in a graphical interface, allowing you to manually select and run tests. It’s an excellent way to visually interact with your tests and see them run in real-time, which can be particularly useful during the development phase when debugging issues.cypress opennpx cypress open Choosing E2E Testing To Start Cypress Test Browsers Available To Run Test On List of Cypress Tests To Choose From Cypress Test Runner With A Passed TestRunning Test Using: package.jsonFor convenience, you might want to add commands directly into your package.json file. This allows you to run specific test scripts or open the Cypress Test Runner with a single command.package.json"scripts": { "test": "echo \"Error: no test specified\" && exit 1", "all-e2e-gui": "npx cypress open --e2e", "home-test-headless": "npx cypress run --spec \"cypress/e2e/home/home-advance.cy.js\"" }, Viewing the package.json file. To view the Run Script | Debug Script options, hover your mouse over the script name and it will display. all-e2e-gui : npx cypress open --e2e - This gives you the ability to launch the Test Runner directly from the terminal. home-test-headless: npx cypress run --spec \"cypress/e2e/home/home-advance.cy.js\ - This is to run your home screen tests in headless mode, ensuring that you can quickly execute these tests without needing to manually input commands each time.ConclusionRunning test scenarios in Cypress is a seamless experience, thanks to its versatility in execution methods. By enhancing your test scenarios and leveraging different ways to execute them, you can ensure that your testing process is both efficient and effective. In the next guide you learn about Connecting Your Cypress Project To Cypress Cloud!
Connecting Cypress Project to Cypress Cloud Connecting your Cypress project to Cypress Cloud is an essential step to enhance your testing workflow. Cypress Cloud offers robust features such as test recording, parallelization, and integration with CI/CD pipelines, which can significantly improve the efficiency and visibility of your test results. In this guide, we’ll walk through the steps to set up and connect your Cypress project to Cypress Cloud, ensuring a seamless integration.

These features include parallel testing, seamless CI/CD integration, and automatic screenshots and videos.In the upcoming guide, we’ll dive deeper into Using Advance Assertions In Cypress.
Using Advanced Cypress Assertions In this advanced assertion guide, we delve into various Cypress commands and their functionalities, focusing on enhancing your testing strategy and ensuring your web application is robust and reliable. These commands, including .next(), .eq(), .include(), .within(), .and(), .then(), and others, provide nuanced control over test scenarios, making them indispensable for comprehensive testing.Understanding Cypress AssertionsThe .next() command in Cypress is used to select the next sibling DOM element within a parent element. This command is particularly useful when you need to perform assertions on elements that are dynamically generated or are sequentially placed in the DOM. For example, if you want to test the navigation menu items in a sequence, you can use .next() to move from one item to the next..next()cy.get('.menu-item') .first() .next() .should('have.text', 'About Us'); This snippet selects the first menu item and asserts that the next sibling has the text About Us, helping ensure the navigation menu is correctly ordered.The .eq() command is another powerful tool in Cypress, used to select an element at a specific index. This is extremely useful for assertions where elements are identical in structure but differ in content or position. For instance, if you’re testing a list of products, you can use .eq() to assert specific properties of each product. .eq()cy.get('.product-item') .eq(2).should('contain', 'Laptop'); In this assertion, Cypress selects the third product item (index:2) and checks if it contains the text Laptop which helps verify the correct rendering of products.The .include() assertion checks if a given string or element contains a specific substring or child element. This is essential for validating partial matches in text or the presence of specific elements within a container. For example, you might want to ensure that a promotional banner includes the keyword Discount. .include()cy.get('.banner') .should('include.text', 'Discount'); This code ensures that the banner element has the word Discount, confirming the presence of expected promotional content.Enhancing Test Coverage with .within() and .and()The .within() command allows you to scope your assertions to a specific portion of the DOM. This is particularly valuable when you have a complex structure with repeated classes or IDs, as it enables precise targeting of elements within a specified container. For example, if you want to validate form fields within a login form, .within() helps isolate the form and perform checks without interference from other elements..within()cy.get('.login-form').within(() => { cy.get('input[name="username"]').type('testuser'); cy.get('input[name="password"]').type('password123'); });In this example, Cypress limits the scope to the .login-form container, ensuring that only the form fields inside it are interacted with, enhancing test reliability.The .and() command chains multiple assertions together, allowing for concise and readable test scripts. When you want to verify multiple properties of an element, .and() provides a clean way to do so in a single command..and()cy.get('.notification') .should('be.visible') .and('contain', 'Success'); This snippet checks that a notification is visible and contains the word Success effectively combining two assertions in a streamlined manner.Leveraging .then() for Synchronous TestingCypress’s .then() command is crucial for handling asynchronous operations and chaining commands in a synchronous manner. This is especially useful when you need to perform complex operations that depend on the results of previous commands. For instance, if you want to fetch data from an API and then validate the response within the test, .then() allows you to manage this flow seamlessly..then()cy.request('GET', '/api/products').then((response) => { expect(response.status).to.eq(200); expect(response.body).to.have.length.greaterThan(0); }); In this example, Cypress sends a GET request to the /api/products endpoint and then uses .then() to assert that the response status is 200 and that the response body contains more than zero products, ensuring the API’s correctness.Building Reliable Tests with CypressCombining these advanced Cypress commands allows developers to create robust and reliable tests that cover a wide range of scenarios, from simple UI checks to complex user flows. Utilizing .next(), .eq(), .include(), .within(), .and(), and .then() helps ensure your application behaves as expected under various conditions, enhancing test coverage and confidence in the application’s stability.ConclusionMastering these commands enables testers to write thorough, maintainable, and efficient Cypress tests for various applications, from single-page to e-commerce platforms. These assertions offer the flexibility to simulate real-world user interactions, ensuring higher-quality web applications and an improved user experience. In the next guide, we will explore Writing API Tests in Cypress.
Writing API Tests in Cypress API testing is a critical component of modern software development, ensuring that your application’s back-end services are robust, reliable, and performant. Cypress, a popular end-to-end testing framework, is not only capable of testing the UI but also excels at API testing. In this guide, we’ll explore how to write API tests in Cypress, dive into some practical examples, and discuss the differences between cy.request and cy.api, two powerful commands for API testing in Cypress.cy.requestCypress provides a seamless way to perform API testing by leveraging its cy.request command. This command is ideal for making HTTP requests to your application’s backend or any third-party services it interacts with. Using cy.request, you can validate the response status, headers, body, and even the timing of API calls, making it an essential tool for API testing in Cypress. For instance, if you’re testing a REST API, you can easily send GET, POST, PUT, or DELETE requests and assert that the server’s responses are as expected.Let’s consider an example where we want to test a simple GET request to retrieve a list of users from an API endpoint. Using cy.request, the test might look something like this:cy.request()describe('API Testing with Cypress', () => { it('should fetch a list of users', () => { cy.request('GET', 'https://jsonplaceholder.typicode.com/users').then((response) => { expect(response.status).to.eq(200); expect(response.body).to.have.length(10); expect(response.body[0]).to.have.property('name'); }); }); });In this example, cy.request sends a GET request to the specified URL. The .then() method is used to handle the response, allowing us to assert that the status code is 200 and that the response body contains an array of users with the expected length and structure. This simple yet powerful approach highlights how Cypress makes API testing straightforward and accessible.cy.apiWhile cy.request is a fantastic tool for making HTTP requests, Cypress also offers the cy.api command through its official plugin, @cypress/plugin-api. This plugin provides a more feature-rich alternative to cy.request and is particularly useful for more complex API testing scenarios. One of the key differences between cy.request and cy.api is that cy.api automatically records requests and responses in the Cypress command log, making debugging and test reviews more intuitive.Consider a scenario where you need to perform a POST request to create a new user and validate the response. Using cy.api, you can write the following test:cy.api()describe('Advanced API Testing with Cypress', () => { it('should create a new user', () => { cy.api({ method: 'POST', url: 'https://jsonplaceholder.typicode.com/users', body: { name: 'John Doe', email: 'john.doe@example.com', phone: '1-770-736-8031 x56442', }, }).then((response) => { expect(response.status).to.eq(201); expect(response.body).to.have.property('name', 'John Doe'); }); }); });In this example, cy.api is used to send a POST request with a JSON payload to create a new user. The test then checks that the server returns a status code of 201 (indicating successful creation) and that the response body contains the correct data. The enhanced logging capabilities of cy.api provide valuable insights into the request and response, making it easier to diagnose any issues that arise during testing.ConclusionCypress is a versatile framework that not only excels at end-to-end testing but also provides robust tools for API testing. Whether you choose to use cy.request for its simplicity and flexibility or cy.api for its enhanced logging and feature set, Cypress makes it easy to implement and maintain high-quality API tests. By incorporating API testing into your Cypress test suite, you can ensure that both your front-end and back-end components work harmoniously together, leading to a more reliable and resilient application.

In the fast-paced world of quality assurance (QA), test code can quickly become complex and challenging to maintain, especially in extensive systems. Test refactoring is a systematic approach to improving the code’s structure without changing its behavior, enhancing readability, maintainability, and overall performance. This guide will walk you through effective techniques and best practices for refactoring test code in Eclipse IDE, a popular development environment used by quality testers.Why Refactor Test Code in Eclipse?Refactoring test code not only simplifies future updates but also reduces the chances of introducing bugs or inconsistencies in your automated tests. By using Eclipse IDE, a comprehensive platform for Java development, you can leverage tools and shortcuts to enhance the refactoring process. Eclipse’s built-in support for automated refactoring, code organization, and error-checking makes it an excellent choice for handling large test suites. Proper refactoring ensures tests are reliable, efficient, and sustainable as your project scales.Identify Problematic Test CodeStart by reviewing your test code for issues that may hinder maintainability or clarity. Tests that are difficult to understand, redundant, or prone to failure often signal the need for refactoring. Use Eclipse’s Code Smells feature to identify areas for improvement, such as duplicated code, overly complex methods, or excessive dependencies. Prioritizing areas that impact test readability or lead to frequent failures will yield the most benefit from refactoring.Keep Tests Small and FocusedOne of the primary goals in refactoring is to ensure each test has a single responsibility. Tests that cover multiple scenarios or actions are not only harder to debug but can also mask issues that may only occur in specific conditions. Refactoring large tests into smaller, focused tests improves readability and maintainability. In Eclipse, you can easily extract methods or classes, allowing for the separation of test responsibilities and making each test easier to manage.Use Descriptive Naming ConventionsDescriptive and consistent naming conventions make your test code self-explanatory, reducing the need for excessive comments or documentation. Rename variables, methods, and classes to reflect their purpose accurately, ensuring that anyone reading the test code understands its functionality without additional context. In Eclipse, the Rename (Shift+Alt+R) refactoring tool allows you to rename elements safely across your codebase, updating references automatically.Best Practices for Refactoring Test Code in EclipseUtilize Parameterized TestsRepeating the same logic across multiple tests with slight variations can lead to redundant code and maintenance issues. Parameterized tests allow you to pass different sets of data to a single test method, reducing code duplication. This approach is particularly effective in unit testing frameworks like JUnit, integrated into Eclipse. Use the JUnit Parameterized class or JUnit 5’s @ParameterizedTest to refactor repetitive tests, creating a cleaner and more maintainable suite.Organize Tests by FunctionalityOrganizing your test cases by functionality, such as creating folders or packages for specific modules, components, or screens, provides a clear structure to your tests. This structure enhances readability and makes it easier to locate specific tests. In Eclipse, you can create custom packages and use annotations to categorize tests, making it easier to navigate large test suites.Refactor Assertions for ClarityAssertions are critical in determining if tests pass or fail, so it’s essential to keep them simple and descriptive. Avoid complex assertion logic that can obscure the intent of the test. Using custom assertion methods can add clarity, especially in complex test scenarios. Eclipse supports a range of assertion libraries, such as AssertJ and Hamcrest, which provide fluent assertion syntax and enhance readability.Leverage Code Coverage ToolsCode coverage tools, like EclEmma for Eclipse, help you identify untested code sections, offering insights into areas that may require additional tests. High coverage does not guarantee perfect tests but helps ensure that your code is well-tested and reliable. Use coverage reports to guide your refactoring efforts and ensure critical paths are tested comprehensively.ConclusionRefactoring test code is a vital practice for maintaining high-quality, reliable test suites. By following these best practices in Eclipse, quality testers can improve code readability, reduce redundancy, and enhance test efficiency. From using parameterized tests and helper methods to adopting mocking and organizing tests by functionality, Eclipse offers numerous tools to simplify and streamline the refactoring process. Embrace these strategies to keep your test code clean, maintainable, and adaptable to future project requirements. Remember, consistent refactoring is the key to sustainable test automation that scales effectively with your application.

For instance: test/unit/ for unit tests. test/widget/ for widget tests. integration_test/ for integration tests.This folder structure will make it easier to maintain and navigate your tests as the application scales.Writing a Simple Unit TestUnit testing in Flutter starts by creating a new .dart file under test/unit/. Here is an example of a simple unit test:Sample Unit Testimport 'package:flutter_test/flutter_test.dart'; import 'package:your_app/math_utils.dart'; void main() { test('Adding two numbers should return correct sum', () { final result = addNumbers(2, 3); expect(result, 5); }); }In this example, addNumbers() is a method from math_utils.dart that you want to test. The test() function helps define the test scenario, and the expect() function is used to validate the result.Running TestsTo run your tests, use the following command in the terminal:bashflutter testThis command will run all the unit and widget tests in your test/ directory.ConclusionSetting up a testing environment in Flutter is an essential task for both QA testers and developers aiming for high-quality, reliable applications. A well-configured environment includes proper setup of the Flutter SDK, addition of essential testing dependencies, organized test files, and the ability to run unit, widget, and integration tests.To dive deeper into Flutter testing, explore the next guide, Writing and Running Unit Tests in Flutter, where you’ll learn how to write effective unit tests and execute them seamlessly.
Writing and Running Unit Tests in Flutter Writing and running unit tests in Flutter is a crucial part of the development process that ensures the stability and reliability of your codebase. In this guide, we’ll cover the essentials of writing and running unit tests in Flutter, enabling you to improve code coverage and boost application stability.Introduction to Unit Testing in FlutterUnit testing is a software testing technique where individual units or components of an application are tested in isolation. In Flutter, a unit test validates a specific part of your logic, typically a function, method, or class, to ensure that it performs as expected. By writing and running unit tests in Flutter, you can catch bugs early, improve the overall reliability of your app, and ensure that each unit behaves predictably even as the code evolves. Flutter provides a simple yet powerful testing environment that includes tools like flutter_test and integration with popular third-party packages. Before diving into writing and running unit tests in Flutter, it’s important to understand the fundamental principles and tools used to create effective unit tests.Setting Up Unit Tests in FlutterTo get started with unit testing in Flutter, you need to set up the appropriate dependencies in your project. Flutter includes a package called flutter_test by default, which provides various functions and utilities that make writing tests easier. You can find it in your pubspec.yaml file:pubspec.yaml dev_dependencies: flutter_test: sdk: flutterWriting Unit Tests in FlutterWhen writing unit tests in Flutter, it is essential to focus on testing individual units of logic in isolation. Unit tests should be short, simple, and easy to maintain. Follow these steps to write a unit test in Flutter:Create a Test FileTest files should be placed in the test/ directory, which Flutter automatically generates when you create a new project. To create a test file, add a new .dart file under the test/unit directory. In this example we will call the file sign_in_screen_unit_test.dart. Flutter Unit TestInspect the Sign Up Screen ControllersWe will focus on examining the functionality of the sign-in screen in our project by exploring the sign_in_screen controller. This controller plays a pivotal role in handling user interactions with the sign-in screen. Specifically, it is responsible for capturing and processing the input data entered in the username and password fields. SigninScreen ControllerThe SignInController controller serves as the bridge between the UI and the business logic, ensuring that the text entered by the user is properly validated and prepared for authentication.Write Your Test CasesWhen writing test cases for the sign-in screen controller, focus on covering all key functionalities and edge cases. Test for valid and invalid inputs, such as correct and incorrect username-password combinations, empty fields, and valid formats.Here’s the code for the SignInController tests:Unit Test Exampleimport 'package:flutter_test/flutter_test.dart'; import 'package:get/get.dart'; import 'package:richapp/controller/sign_in_controller.dart'; void main() { group('SignInController Tests', () { late SignInController controller; setUp(() { controller = Get.put(SignInController()); }); tearDown(() { Get.delete<SignInController>(); }); test('should initialize with empty text controllers', () { expect(controller.emailOrUserNameController.text, isEmpty); expect(controller.passwordController.text, isEmpty); expect(controller.emailController.text, isEmpty); }); test('should update emailOrUserNameController text correctly', () { controller.emailOrUserNameController.text = 'testuser'; expect(controller.emailOrUserNameController.text, 'testuser'); }); }); } Understanding the Tests Test Initialization (setUp and tearDown) Each test is set up with a fresh instance of SignInController using Get.put, ensuring no shared state between tests. After each test, tearDown ensures the controller is removed using Get.delete. Testing Default Values The first test checks whether the emailOrUserNameController, passwordController, and emailController are initialized with empty text. This ensures the controller starts in a clean state. Testing Text Update The second test verifies that the text in emailOrUserNameController updates as expected when modified. This is a simple check for setter functionality.Running Unit Tests in FlutterOnce you have written your unit tests, it’s time to run them to ensure your code works as expected. You can run unit tests in Flutter using the following command:Run Flutter Unit Test# Runs all the tests flutter test # Run tests on in the unit directory flutter test/unit/ This command runs all the test files located in the test/ directory, including any subdirectories such as test/unit/, and displays the results in the terminal. If you wish to target a specific directory or test file, you can do so by providing the relative file path as an argument: Run Flutter Test vis Pathflutter test test/unit/sign_in_screen_widget_test.dartFlutter will execute the test cases and report the results, including any errors or failed tests. It is good practice to frequently run tests during development to catch issues early. Flutter Unit Test ResultsBest Practices for Writing and Running Unit Tests in FlutterTo ensure that your unit tests are effective and easy to maintain, consider the following best practices: Keep Tests Simple and Focused: Each test should focus on one specific behavior. This makes it easier to identify the root cause of any failure. Use Meaningful Test Names: Clearly describe what the test is validating so that anyone reading the test results understands the purpose of the test. Run Tests Frequently: The sooner you catch a bug, the easier it is to fix. Run tests frequently to catch issues as soon as possible. Ensure Code Coverage: Aim for high test coverage, but remember that quality is more important than quantity. Cover critical logic and edge cases, but avoid writing redundant tests.ConclusionWriting and running unit tests in Flutter is a fundamental practice for ensuring the reliability and stability of your application. This unit test demonstrates how to ensure your SignInController behaves as expected in terms of initialization, state updates, and resource management. Writing clear, focused tests like these can help catch bugs early and maintain a robust codebase.To explore the next step in Flutter testing, check out our guide on Widget Testing in Flutter, where you’ll learn how to test individual widgets effectively to enhance your application’s quality.
Widget Testing in Flutter Widget Testing in Flutter is an essential part of the development and QA process, ensuring that individual components of a Flutter app function as expected. Unlike unit tests that focus on the smallest pieces of logic or integration tests that test larger portions of the app, widget testing focuses specifically on validating the behavior of UI components. By effectively employing widget tests, you can validate that widgets render correctly, handle user interactions as expected, and ensure UI changes propagate correctly. This guide aims to provide QA testers and developers with a clear understanding of widget testing in Flutter and practical steps to implement it effectively.What Is Flutter Widget Testing?Widget testing is all about ensuring that individual widgets in your Flutter application behave as expected. Unlike unit tests that focus on logic and computations, widget tests verify the UI and its interactions. For our Sign-In screen, we’ll simulate user actions and validate the UI’s response to these interactions. Running All Widget Tests in VSCodeSetting Up the Test EnvironmentBefore writing widget tests, you need to set up a robust test environment. In this project, I’ve used flutter_test for writing tests, along with ScreenUtil for responsive layouts and GetX for state management and navigation. Here’s how we prepare the environment to ensure smooth testing workflows.To get started with widget testing, follow these steps: Creating Widget Test File Create a New Test File: Navigate to the test/unit directory in your Flutter project and create a new Dart file. Since we're testing the sign in screen, let's name itsign_in_widget_test.dart. Add a Main Function: Inside the newly created file, add the main function to act as the entry point for your test. It should look like this: void main {}. Set Up the Test Environment: Add any dependencies or utilities you need for testing within the main function. For example, if you are testing a widget with routes or dependencies, ensure those are set up properly. Add a Teardown Function: After each test, it’s essential to reset the state to avoid conflicts between tests. Use the tearDown function for this purpose tearDown(() { Get.reset(); }); Below is a snippet I used to handle building the widget page and managing routes using GetX.Function: buildTestWidgetWidget buildTestWidget(Widget widget) { return ScreenUtilInit( designSize: const Size(430, 932), builder: (_, __) => GetMaterialApp( home: widget, initialRoute: '/', getPages: [ GetPage(name: '/', page: () => SignInScreen()), GetPage(name: '/signUpScreen', page: () => SignUpScreen()), GetPage(name: '/bottomNavigationScreen', page: () => HomeScreen()), ], ), ); }Writing Tests for the Sign-In ScreenVerifying Text Fields and ButtonsThe first step is to ensure that all key widgets are present on the screen. These include the email and password fields, as well as the Sign-In button. Verify email, password, and sign-in button keysWidget Test: Verify email, password, and sign-in button keystestWidgets('Verify email, password, and sign-in button keys', (WidgetTester tester) async { await tester.pumpWidget(createTestScreenWidget(SignInScreen())); await tester.pumpAndSettle(); // Verify widgets by key expect(find.byKey(Key('email_username')), findsOneWidget); expect(find.byKey(Key('password')), findsOneWidget); expect(find.byKey(Key('sign_in_btn')), findsOneWidget); });This test validates that the text fields and button are part of the widget tree, using their unique keys for identification.Testing Button Clicks and NavigationButtons are the core of user interactions. Let’s ensure the Sign-In button is clickable and navigates to the correct screen. Tapping Sign In Button Sign In Button Routing On the Home ScreenWidget Test: Sign In button is clickabletestWidgets('Sign In button is clickable', (WidgetTester tester) async { await tester.pumpWidget(createTestScreenWidget(SignInScreen())); await tester.pumpAndSettle(); // Find the button and tap it final primaryButtonFinder = find.byKey(Key('sign_in_btn')); await tester.tap(primaryButtonFinder); await tester.pumpAndSettle(); // Verify navigation expect(find.byType(HomeScreen), findsOneWidget); });This test not only verifies the button’s presence but also confirms successful navigation to the Home screen.Testing LinksLinks like Forgot Password or Sign Up are equally important. Here’s how to test that the Forgot Password link opens the appropriate modal: Widget Testing LinksWidget Test: Forgot Password link is clickabletestWidgets('Forgot Password link is clickable', (WidgetTester tester) async { await tester.pumpWidget(createTestScreenWidget(SignInScreen())); await tester.pumpAndSettle(); final forgotPasswordFinder = find.byKey(Key('forgot_password_link')); await tester.tap(forgotPasswordFinder); await tester.pumpAndSettle(); // Verify modal content expect(find.text('Forgot Password'), findsOneWidget); }); Similarly, you can test the navigation triggered by the Sign Up link:Widget Test: Tap on Sign Up and navigates to the Sign Up screentestWidgets('Tap on Sign Up and navigates to the Sign Up screen', (WidgetTester tester) async { await tester.pumpWidget(createTestScreenWidget(SignInScreen())); final signUpTextFinder = find.text(Strings.signUp); await tester.tap(signUpTextFinder); await tester.pumpAndSettle(); // Verify navigation expect(find.byType(SignUpScreen), findsOneWidget); });These tests ensure your app’s routes are functioning correctly.Debugging Common IssuesDuring widget testing, you might encounter common errors like RenderFlex overflow or issues with animations. Suppressing these in tests, as shown below, can help: Flutter Error HandlingFlutter Error HandlingFlutterError.onError = (FlutterErrorDetails details) { if (details.exceptionAsString().contains('A RenderFlex overflowed')) { return; // Suppress the error } FlutterError.presentError(details); }; Best Practices for Widget Testing in Flutter Test Small Units: Widget tests should be granular, focusing on small components. This ensures that errors can be easily traced to individual widgets. Mock External Dependencies: When widget testing in Flutter, try to isolate the widget from any external dependencies such as APIs or services. This is achieved using mock data or mock functions. Use Golden Tests: Golden tests can be helpful to ensure your widget matches an expected visual appearance. Golden testing captures the rendered widget as an image and compares it to a reference image to catch unintended UI changes. Run Tests Regularly: Widget tests should be run frequently as part of your CI/CD pipeline to catch bugs early and maintain UI stability.Advantages of Widget Testing in Flutter Faster Execution Reliable Feedback Cost-Efficient Debugging Widget tests run much faster compared to integration tests, as they do not require the full app context to be loaded.Since widget tests run in isolation, they provide highly reliable feedback on individual component behavior without interference from other parts of the application.Early detection of UI bugs prevents costly reworks down the line, especially as your Flutter application scales in complexity.ConclusionWidget testing in Flutter is an indispensable tool for ensuring the reliability and correctness of user interface components. By incorporating widget testing into your development and quality assurance workflows, you can confidently validate the behavior of your app’s building blocks, ultimately delivering a better experience to your users. From understanding the basics to writing comprehensive tests and following best practices, this guide serves as a roadmap for mastering widget testing in Flutter.To take your testing knowledge further, explore our next guide on Integration Testing in Flutter, where we dive deeper into testing complete workflows and interactions within your app.
Integration Testing in Flutter Flutter integration testing is a crucial step in ensuring that your app works seamlessly as a whole. It allows us to verify user flows, interactions between widgets, and the final output as seen by the user. In this guide, I’ll walk you through the process of creating an integration test for a Flutter app using a complete flow from a WelcomeScreen to a HomeScreen. By focusing on the text fields, buttons, and navigation routes, we’ll simulate real-world user interactions. If you’re looking to strengthen your Flutter testing toolkit, this is a great place to start.What is Integration Testing in Flutter?Integration testing in Flutter bridges the gap between unit tests and end-to-end tests. While unit tests validate individual methods or widgets, integration tests validate entire user flows across screens. This ensures the components work together harmoniously.Let’s take a practical example: a Sign In flow. We’ll verify that all interactive elements, such as text fields and buttons, function correctly. Additionally, we’ll ensure the navigation routes transition the user seamlessly between screens. Our integration test will involve three screens: WelcomeScreen , SignInScreen , and HomeScreen . Flutter Integration Test Running On iPhoneSetting Up Flutter Integration TestingWe begin with the following Flutter widget code. It sets up three key screens: WelcomeScreen: The starting screen offering options to [direction]Sign In[/direction] or [direction]Sign Up[/direction]. SignInScreen: The screen where users input their credentials. HomeScreen: The destination screen once a user signs in successfully.Writing Your First Integration TestTo start, create a new file in the integration_test directory, such as sign_in_screen_e2e_test.dart. This file will define tests to interact with the sign screen, simulating user flows like signing in. Flutter Integration Test File NameBegin by importing the necessary packages, including flutter_test for testing, integration_test for simulating interactions, and main.dart from your app. Use an alias like app for main.dart to avoid naming conflicts and make it clear you’re referencing your app’s entry point.Initialize the integration test environment by calling IntegrationTestWidgetsFlutterBinding.ensureInitialized(). This setup allows you to simulate real-world app usage.Integration Test – main.dart as appimport 'package:flutter/material.dart'; import 'package:flutter_test/flutter_test.dart'; import 'package:integration_test/integration_test.dart'; import 'package:get/get.dart'; import 'package:richapp/routes/routes.dart'; import 'package:richapp/main.dart' as app; void main() { IntegrationTestWidgetsFlutterBinding.ensureInitialized(); //...Testing the WelcomeScreenThe first step in our test is verifying the WelcomeScreen UI elements and functionality. The test checks if SIGN IN and SIGN UP buttons are displayed and functional. Inside the testWidgets function, call app.main() to launch your app. Flutter App Welcome ScreenWelcome Screen ElementstestWidgets('Complete flow from WelcomeScreen to HomeScreen', (WidgetTester tester) async { // Builds and loads the test app app.main(); // Wait for the WelcomeScreen to load await tester.pumpAndSettle(); // Verify WelcomeScreen is displayed expect(find.text('SIGN IN'), findsOneWidget); expect(find.text('SIGN UP'), findsOneWidget); // Tap the Sign In button on the WelcomeScreen await tester.tap(find.text('SIGN IN')); //await tester.pumpAndSettle(); await tester.pump(Duration(milliseconds: 1000)); //... The expect assertions confirm the presence of buttons, and tap simulates the user’s action of tapping SIGN IN .Testing the Sign In ScreenAfter navigating to the SignInScreen, the test verifies the presence of input fields for email and password, as well as the SIGN IN button. iPhone: Sign In ScreenSignIn Screen Elements// Verify SignInScreen is displayed expect(find.byKey(Key('email_username')), findsOneWidget); expect(find.byKey(Key('password')), findsOneWidget); expect(find.byKey(Key('sign_in_btn')), findsOneWidget); // Enter email and password await tester.enterText(find.byKey(Key('email_username')), 'test@example.com'); await tester.enterText(find.byKey(Key('password')), 'password123'); await tester.pump(Duration(milliseconds: 1000)); // Tap the Sign In button await tester.tap(find.byKey(Key('sign_in_btn'))); await tester.pump(Duration(milliseconds: 1000)); //...The enterText method mimics typing credentials into the fields.Testing the HomeScreen Finally, the test validates navigation to the HomeScreen and confirms key UI elements like the AppBar, Dashboard text, and menu icon are present. iPhone: Home ScreenHome Screen Elements// Simulate navigation to HomeScreen Get.toNamed(Routes.bottomNavigationScreen); await tester.pump(Duration(milliseconds: 1000)); // Verify HomeScreen is displayed expect(find.byType(AppBar), findsOneWidget); expect(find.text('Dashboard'), findsOneWidget); expect(find.byKey(Key('menu-icon')), findsOneWidget); //...By checking for these elements, we confirm that the user has successfully reached the HomeScreen.Run Testflutter test integration_test/app_test.dartBest Practices for Integration Testing in Flutter Use Realistic Data When performing integration testing in Flutter, it is best to use realistic test data that mimics real-world scenarios. This helps in identifying issues that could occur in actual usage, such as invalid user input or poor network conditions. Test Complete User Journeys Integration tests should cover complete user journeys rather than isolated actions. For instance, testing a purchase flow should cover product selection, adding to the cart, and completing the checkout. This ensures that all interactions and dependencies between components are working correctly. Optimize Test Execution Time Integration tests can take longer to run compared to unit tests. Make sure to optimize your tests by avoiding unnecessary waits and focusing on critical user flows. This reduces the time required for continuous integration and helps maintain productivity. Device Compatibility Flutter integration tests should be run on both Android and iOS to ensure compatibility across platforms. Consider using cloud-based testing services, such as Firebase Test Lab, to automate the execution of integration tests on a variety of devices.Common Challenges in Integration TestingWhile integration testing in Flutter is immensely valuable, it comes with its challenges. Managing Dependencies Maintenance Managing dependencies such as network responses can be cumbersome. To solve this, consider mocking or stubbing API calls to ensure tests are deterministic and can run without external dependencies. As the Flutter app undergoes changes, your integration tests may need frequent updates to align with new layouts or interactions. To mitigate this, ensure your tests are modular and maintainable.ConclusionIntegration testing in Flutter is a key component of building robust, high-quality mobile applications. By ensuring that all parts of the app work seamlessly together, you reduce the risk of unexpected issues arising in production. Setting up integration tests using the integration_test package allows QA testers and developers to verify entire user flows, enhancing app stability and improving user experience.Keep exploring and integrating Flutter integration testing into your development process. Happy testing!

Writing Your First Patrol Test Case Patrol is an excellent tool for automating Flutter app tests, ensuring that essential app functionalities work as expected across various devices. In this guide, we will walk through writing your first Patrol test, specifically focusing on a common user journey: signing into an app.Setting Up Your Patrol TestBefore diving into the test, ensure that you have Patrol properly installed in your project. With everything in place, let’s begin by writing a test that checks the functionality of a basic sign-in screen. Welcome Screen Sign In ScreenThe sign-in screen typically includes email and password input fields, followed by a sign-in button. Our goal in this Patrol test is to automate the process of entering the email and password, tapping the sign-in button, and verifying the navigation to the dashboard screen.The test begins with a basic import of necessary packages, such as flutter_test for testing utilities and patrol for test automation:Dartimport 'package:flutter/material.dart'; import 'package:flutter_test/flutter_test.dart'; import 'package:patrol/patrol.dart'; import 'package:richpay_app/main.dart' as app;By importing these packages, you set up a testing environment that allows you to interact with the app’s widgets during test execution.Structuring the Patrol TestNext, we define our Patrol test. In this example, we are testing the sign-in process by creating a test that verifies the email input, password input, and sign-in button functionality:Dartvoid main() { patrolTest( 'Sign In Screen - Verifies email input, password input, and sign-in button', ($) async { // Start the app app.main(); await $.pumpAndTrySettle();The patrolTest function defines a specific test case, and inside the function, we start the app using app.main(). This ensures that your app runs in the testing environment, ready to simulate user interactions.Interacting with WidgetsAfter starting the app, we simulate a tap on the sign-in button that appears on the welcome screen. We use the find.byKey method to locate the button using its unique Key:Dartfinal welcomeSignInButton = $(find.byKey(const Key('sign_in_btn'))); await $(welcomeSignInButton).tap(); await $.pumpAndSettle();The $(find.byKey()) function finds the button, and tap() simulates the user pressing it. The pumpAndSettle() method ensures that the app has finished rendering and settles before the next step. Widget Inspector Sign In ButtonEntering Text into Input FieldsNow, let’s verify and interact with the email and password input fields. We first locate the input fields using their respective keys and then simulate entering text:Dartfinal emailTextBox = $(find.byKey(const Key('email_username'))); await $(emailTextBox).enterText('test@gmail.com'); final passwordTextBox = $(find.byKey(const Key('password'))); await $(passwordTextBox).enterText('test123');The enterText() function is essential in automating user input for testing login forms, ensuring that valid text is entered into the relevant fields during the test. Widget Inspector Email & PasswordFinalizing the Test by Tapping the Sign-In ButtonAfter entering the login credentials, we locate and tap the sign-in button to submit the form:Dartfinal signInSignInButton = $(find.byKey(const Key('sign_in_btn'))); await $(signInSignInButton).tap(); // Wait for the navigation to complete after sign-in await $.pumpAndSettle(); Just like before, we use find.byKey to locate the sign-in button and simulate the tap. The app is given time to navigate by calling pumpAndSettle() to ensure all animations and transitions are complete before continuing. Widget Inspector Sign In ButtonVerifying the DashboardFinally, after the sign-in process completes, we want to verify that the user has successfully navigated to the dashboard. We can do this by checking if a specific widget or text related to the dashboard is visible: Widget Inspector Verify Dashboard TextDartexpect(find.text('Dashboard'),findsOneWidget); In this case, we check if the text Dashboard is displayed, confirming that the sign-in was successful and the user has reached the dashboard screen.ConclusionIn the next guide, we’ll dive deeper into Organizing Test Suites in Patrol, helping you structure your tests efficiently for larger applications.

Organizing Test Suites in Patrol Organizing your test suites efficiently is crucial for maintaining a clean, scalable, and maintainable test architecture, especially when using Patrol, a robust mobile testing framework. One effective strategy is to group tests by screen name, allowing you to organize tests into directories that correspond to the screens in your app. This practice not only improves clarity but also makes it easier for your QA team to locate and maintain specific test cases as your project evolves. Get Access to the Test App & FrameworkPro Members unlock hands-on access to our expertly crafted frameworks. PRO MEMBER Organizing Tests by Screen NameWhen testing a mobile application, screens often represent a core aspect of the user flow. Each screen might have different behaviors, elements, and functionalities that require unique test cases. By organizing tests by screen name, you ensure that: Tests are easily navigable: Team members can quickly find tests related to specific app screens. Reusability and maintenance are enhanced: Updates to screens or features can be isolated to relevant directories without impacting the entire test suite. Collaboration is smoother: Teams can focus on specific screens without having to comb through large, unrelated test files.Create Screen-Specific DirectoriesIn Patrol, you can organize your tests into directories that correspond to specific screens in your app. The following structure is an example:screen directoriesintegration_test/ └── e2e/ ├── dashboard/ │ └── dashboard_test.dart ├── menu/ │ └── menu_test.dart ├── notifications/ │ └── notifications_test.dart ├── profile/ │ └── profile_test.dart ├── sign_in/ │ └── sign_in_test.dart └── sign_up/ └── sign_up_test.dart Organizing Tests by Screen NameEach directory contains the relevant test files for that particular screen. This keeps the tests clean and organized. Here’s how each folder corresponds to the app: dashboard/: Tests focused on ensuring the functionality of the user dashboard. menu/: Tests for menu navigation, clicking and validating the menu items. notifications/: Tests to verify the functionality of the notification screen. profile/: Tests centered on user profile management, and updating personal details. sign_in/: Tests for the sign-in screen, focusing on logging in and error handling. sign_up/: Tests for the sign-up screen, ensuring registration is working as expected.Writing Tests for Each ScreenLet’s dive deeper into crafting a sample test for the dashboard screen. This test suite will encompass various tests to ensure that essential elements are displayed correctly, including the Dashboard title, key transfer functions such as Deposit, Withdraw, Send, and Request, as well as the transaction history components.dashboard_test.dartimport 'package:flutter/material.dart'; import 'package:flutter_test/flutter_test.dart'; import 'package:patrol/patrol.dart'; import 'package:richpay_app/main.dart' as app; void main() { patrolTest( 'Dashboard Screen - Verify the elements on the dashbaord', ($) async { // Start the app app.main(); await $.pumpAndTrySettle(); final welcomeSignInButton = $(find.byKey(const Key('sign_in_btn'))); await $(welcomeSignInButton).tap(); await $.pumpAndSettle(); // // Verify the presence of email/username input field and enter text final emailTextBox = $(find.byKey(const Key('email_username'))); await $(emailTextBox).enterText('test@gmail.com'); final passwordTextBox = $(find.byKey(const Key('password'))); await $(passwordTextBox).enterText('test123'); final signInSignInButton = $(find.byKey(const Key('sign_in_btn'))); await $(signInSignInButton).tap(); // Wait for the navigation to complete after sign-in await $.pumpAndSettle(); // Add further assertions if needed expect(find.text('Dashboard'), findsOneWidget); expect(find.text('Deposit'), findsAtLeast(1)); expect(find.text('Withdraw'), findsOneWidget); expect(find.text('Send'), findsOneWidget); expect(find.text('Request'), findsOneWidget); expect(find.text('Transactions History'), findsOneWidget); }, ); } Naming Conventions and Test FlowUsing consistent naming conventions is essential. Screen directories and test files should be named based on the screens they test. This eliminates confusion, especially as your test suite grows. For example: Patrol Test Based On Screen dashboard_test.dart: Tests related to the dashboard screen. profile_test.dart: Tests related to the profile screen.When writing these tests, ensure that: 1 Self Contained 2 Descriptive Test Names Each test is self-contained: A test should not rely on another test. This enhances the modularity of your test suite.Each test function should clearly describe the functionality being tested, such as verify_profile_update or test_sign_up_with_invalid_credentials. Running Tests by DirectoryPatrol allows you to run tests for a specific directory if you want to focus on tests for a particular screen. Here’s how to run tests for the sign_in screen using the CLI:Run all test in ‘sign_in’ directorypatrol test -t integration_test/e2e/sign_in/ Running Patrol Test Sign In Screen Directory Tip: Running On IOS?If you’re running your Patrol test on an iOS device, make sure to pass the -d flag followed by the device’s UDID. This ensures that the correct device is targeted and avoids any running issues that could occur if it’s omitted. For example:Using the Device Flag For iOSpatrol test -d D76D6C18-03AE-46E0-A732-C46608EBF212 -t integration_test/e2e/sign_inIn this command, D76D6C18-03AE-46E0-A732-C46608EBF212 is the UDID of your iOS device, and the -t flag is used to specify the test file, such as integration_test/e2e/sign_in.This command will execute all tests within the sign_in directory, making it easy to target specific areas of the app without running the entire test suite.ConclusionOrganizing test suites by screen name in Patrol helps maintain clean, efficient, and scalable test cases. By creating screen-specific directories, you enhance collaboration and streamline the testing process. This structure becomes especially helpful as your app grows and new features are added. Following this organization strategy ensures that your tests are well-structured, easy to manage, and scalable for future updates.In the next lesson, we’ll dive deeper into Organizing Test Suites by Screen Name in Patrol, where you’ll learn how to effectively categorize your tests and maintain a robust testing workflow.
Advanced and Native Interactions in Patrol In the realm of mobile testing, achieving seamless user interactions is paramount to ensuring a smooth user experience. Patrol Testing provides an effective framework for automating and validating these interactions, including both advanced and native functionalities. This guide explores the intricacies of advanced and native interactions in Patrol, offering insights into best practices, techniques, and methodologies to elevate your testing strategies.Advanced InteractionsAdvanced interactions in Patrol Testing encompass a variety of user actions that simulate complex user behaviors. These interactions are crucial for ensuring that applications function as intended in real-world scenarios. Here are some key types of advanced interactions:GesturesGestures such as swipes, pinches, and rotations play a crucial role in navigating and interacting with mobile applications. These gestures simulate the natural user interactions within an app, and automating them ensures your tests closely mimic real-world usage scenarios. Patrol makes it easy to automate gestures with its intuitive syntax, allowing testers to seamlessly simulate complex interactions such as swipes.Swipe Left// Verify the first card is visible initially expect(find.byType(CardWidget), findsWidgets); // Swipe left to scroll right through the cards await $.tester.drag(find.byType(CarouselSlider), const Offset(-300, 0)); await $.pumpAndSettle();A left swipe action mimics the user’s gesture of dragging the screen to the left, often used to reveal the next set of items in a carousel or slider. Swiping Left in Patrol Card Verification: The test first checks if the CardWidget is visible. Swipe Action: The swipe is performed by dragging the CarouselSlider with an offset of -300 on the X-axis, which simulates a leftward swipe. Settling: After the swipe, we call await $.pumpAndSettle(); to allow the animations or transitions to complete.Swipe Right// Verify the first card is visible initially expect(find.byType(CardWidget), findsWidgets); // Swipe right to scroll right through the cards await $.tester.drag(find.byType(CarouselSlider), const Offset(300, 0)); await $.pumpAndSettle();Similarly, a right swipe mimics the user’s gesture of dragging the screen to the right, often to scroll back to the previous items in the carousel. Swiping Right in Patrol Card Verification: The test first checks if the CardWidget is visible. Swipe Action: The swipe is performed by dragging the CarouselSlider with an offset of 300 on the X-axis, which simulates a rightward swipe. Settling: After the swipe, we call await $.pumpAndSettle(); to allow the animations or transitions to complete.Double TapCertain functionalities depend on double tap actions. Patrol currently doesn’t have built-in method for doubleTapping on an element. In this scenario we will use the tap feature twice. Tip: Double Tap in Patrol TestingPatrol doesn’t have a built-in doubleTap method for interacting with Flutter widgets in the app. However, Patrol provides a $.native.doubleTap feature, which is specifically used for WebViews and elements that are native to the device itself, rather than elements within the Flutter app. To simulate a double-tap in a Flutter app, you can manually call tap twice with a small delay in between.Double Tapawait $.tap(find.text('Double Tap for App Info')); await $.tap(find.text('Double Tap for App Info')); expect(find.text('Rich Pay v2.0.0 | Patrol Version 3.2.0'), findsOneWidget);This command allow you to validate double taps and the expectation ensuring comprehensive coverage of user actions. Mimicking DoubleTap FeatureNative InteractionsNative interactions refer to the ability to interact with platform-specific features and components, significantly enhancing the overall user experience by testing your application in real-world scenarios. Patrol provides robust support for accessing and interacting with native functionalities on both Android and iOS devices. This feature allows testers to simulate device-level interactions, ensuring that applications behave correctly under various system conditions.Accessing Device FeaturesPatrol allows you to interact with several native device features, such as WiFi, GPS, dark mode, and system dialogs. These interactions are invaluable for testing how your app reacts to changes in device settings or permissions. For instance, when testing a weather app that relies on location services, you can simulate turning GPS on and off, or granting and denying location permissions.Below is a sample code that demonstrates how you can access and manipulate some of these native features:Native FeaturespatrolTest('demo', (PatrolIntegrationTester $) async { await $.pumpWidgetAndSettle(AwesomeApp()); // prepare network conditions await $.native.enableCellular(); await $.native.disableWifi(); // toggle system theme await $.native.enableDarkMode(); // handle native location permission request dialog await $.native.selectFineLocation(); await $.native.grantPermissionWhenInUse(); // tap on the first notification await $.native.openNotifications(); await $.native.tapOnNotificationByIndex(0); });Interacting with Native Alerts and DialogsMany applications utilize native alerts and dialogs for user notifications or confirmations. Patrol can handle these interactions effectively:System Dialog > Grant Permissionif (await $.native.isPermissionDialogVisible()) { await $.native.grantPermissionWhenInUse(); } Patrol Grant Access To System PromptThis sequence ensures that your tests can manage alerts, providing a seamless user experience.ScrollingTesting native scrolling is crucial for applications with long lists or multiple screens. Patrol facilitates these actions with simple commands:scrollToawait $(find.byKey(Key('request-tab'))).tap(); await $.pumpAndSettle(); await $(find.text('CONTINUE')).scrollTo(); await $(find.text('CONTINUE')).tap(); Patrol ScrollTo FeatureInteracting with WebViewsWebViews are a common element in mobile applications, allowing developers to display web content within a native app. Testing WebViews can be challenging due to the mixed nature of web elements inside a native container, but Patrol provides efficient ways to interact with them. This guide will walk you through testing WebView elements using Patrol, ensuring your app’s web interactions work seamlessly.WebViews// Tap on the button that opens the WebView page await $(find.text('Open Web Page')).tap(); // Allow the WebView to load by waiting and trying to settle for 15 seconds await $.pumpAndTrySettle(timeout: Duration(seconds: 15)); // Enter name into the first text input field (index 0) await $.native.enterTextByIndex( 'John Smith', index: 0, // Adjust index based on your specific form structure keyboardBehavior: KeyboardBehavior.alternative, ); // Enter email into the second text input field (index 1) await $.native.enterTextByIndex( 'student@masteringqa.com', index: 1, // Adjust index based on your specific form structure keyboardBehavior: KeyboardBehavior.alternative, ); // Enter password into the third text input field (index 2) await $.native.enterTextByIndex( 'test1234', index: 2, // Adjust index based on your specific form structure keyboardBehavior: KeyboardBehavior.alternative, ); Patrol Interacting With WebViewsPatrol uses the enterTextByIndex function to simulate typing text into specific input fields in the WebView. The index parameter specifies the position of the field within the WebView. The KeyboardBehavior.alternative parameter allows you to manage how the keyboard behaves during interactions, this is very crucial when working with IOS devices.Best Practices for Advanced and Native Interactions Use Assertions Wisely: Always validate expected outcomes after performing interactions. For instance, after a swipe action, assert that the correct screen is displayed or that the expected element is visible. Maintain Readable Code: Write clear and maintainable test scripts. Using descriptive names for actions and elements helps other team members understand your tests. Leverage Wait Commands: Utilize wait commands effectively to ensure that your tests are resilient to timing issues. Implementing proper waits between actions minimizes false negatives. Combine Interactions: Test complex user scenarios by combining multiple interactions. For example, you might simulate a user logging in, then navigating to a profile page and updating details.ConclusionMastering advanced and native interactions in Patrol Testing is essential for delivering high-quality mobile applications. By utilizing Patrol’s capabilities to simulate user behaviors and engage with native features, you can ensure a seamless user experience. Adopting the best practices in this guide will help you create effective and maintainable tests for comprehensive application validation.
