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. Get Access to the Test App & FrameworkPro Members unlock hands-on access to our expertly crafted frameworks. PRO MEMBER Device Info: Pixel 8 | API 33 Tip: Please ensure you have an emulator created and running before hand.Connecting ADB to an EmulatorOnce your emulator is running, you need to connect ADB to it.Open Terminal: Launch the Terminal App on your on your Mac. Launch TerminalNavigate to ADB Directory: Navigate to the directory where ADB is installed. This is typically in the platform-tools directory of your Android SDK.bashcd /Users/{UserName}/Library/Android/sdk/platform-tools Changing Directory To Platform ToolsCheck Connected Devices: Run the following command to list connected devices and emulators.bashadb devices List of Running Devices Displayed You should see your emulator listed. If not, restart the ADB server. In Terminal paste the command below:bashadb kill-server adb start-serverCommon ADB CommandsHere are some essential ADB commands for quality testing:Installing an APK: To Install an application on the emulator. 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. Android Studio Profiler > Select Active Emulator CPU Profiler: Monitor your app's CPU usage, threads, and methods. Android Studio Profiler > CPU Profiler Memory Profiler: Track memory allocation and garbage collection. Android Studio Profiler > Memory ProfilerRunning Performance Tests Profile Your App: Use the profiler tools to identify performance issues during test execution.Memory Profiler Record Android Studio > Memory Profiler Record Android Studio > Memory Profiler ResultsCPU Profiler Record Android Studio > CPU Profiler Record Android Studio > CPU Profiler ResultsConclusionPerformance testing on Android emulators is essential for optimizing your app and ensuring it performs well under various conditions.

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.

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. 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!

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!
