Setting Up LambdaTest for Automated Testing

Estimated reading: 15 minutes 53 views

If you’re looking to perform cloud-based cross-browser testing, LambdaTest provides a powerful infrastructure to automate tests with different frameworks, including Selenium + TestNG using Java. In this guide, I’ll walk you through the step-by-step process of setting up LambdaTest for automated testing, from signing up to executing test cases seamlessly.

What We’ll Cover

Signing Up for LambdaTest

To begin using LambdaTest, you first need to create an account. You can either sign up using your email or simply log in with an existing Google account.

Visit LambdaTest and click Get Started Free
Choose your preferred method (email or Google account) to register.
Once signed in, you'll be redirected to the LambdaTest dashboard.

Accessing Web Automation Testing

Once you’re inside the dashboard, follow these steps to set up automated testing:

Navigate to the side menu and select Automation Web Automation .
Next a screen displays whether you want to use a Demo Project or Configure Test Suite . Select the Configure Test Suite option.
You'll be prompted to select a test framework. While you can choose any, for this guide, we will use Selenium Java TestNG

Cloning the Sample Project

LambdaTest provides a sample Java-TestNG-Selenium project to help you get started quickly. To clone the repository, execute the following commands in your terminal:

Clone LamdaTest Seleniium + TestNG project

git clone https://github.com/LambdaTest/Java-TestNG-Selenium
cd Java-TestNG-Selenium

Configuring Your Credentials

Before running your tests, you need to configure your LambdaTest credentials. Set your LT_USERNAME and LT_ACCESS_KEY in an environment file.

Linux/macOS
Windows (CMD)

Linux/macOS

export LT_USERNAME=jahmalrichardpro
export LT_ACCESS_KEY=iHE17Brcqb7zxbkcwJ9bcqR9ByHuFe0irHEmKlITmCdaGBktnn

Windows

set LT_USERNAME=jahmalrichardpro
set LT_ACCESS_KEY=iHE17Brcqb7zxbkcwJ9bcqR9ByHuFe0irHEmKlITmCdaGBktnn

Configuring Browser Capabilities

Now, let’s set up browser capabilities inside the TestNGTodo1.java file to define test configurations.

Browser Desired Capablilites

ChromeOptions browserOptions = new ChromeOptions();
HashMap<String, Object> ltOptions = new HashMap<String, Object>();
ltOptions.put("username", "jahmalrichardpro");
ltOptions.put("accessKey", "iHE17Brcqb7zxbkcwJ9bcqR9ByHuFe0irHEmKlITmCdaGBktzz");
ltOptions.put("project", "LambdaTest Selenium Automation");
ltOptions.put("w3c", true);
ltOptions.put("plugin", "java-testNG");

browserOptions.setCapability("LT:Options", ltOptions);

Setting Up Build and Test Configuration

Build Settings

Browser Version: Chrome 133
( Please confirm your version with you Chrome Browser in the About section.)
Build Name: Java Selenium TestNG Test
Automation Project Name: LambdaTest Demo Web Automation

Test Configuration

Test Configs	Enabled/Disabled
Test Name	`MQA LambdaTest Demo`
Test Tags	`Selenium`, `TestNG`, `Automation`
Screenshot Capture
Record Video
Console Logs
Network Logs

Local/Tunnel
Keep the Local/Tunnel option off unless you have the necessary configurations set up. Enabling it without proper setup will result in an error when executing your test.

Updating the Tests

Once everything is configured, copy the capabilities in the @BeforeMethod in this file src/test/java/com/lambdatest/TestNGTodo1.java so we can execute the test cases with the new capabilities configurations.

Update the TestNG XML File

Before we can run the test via the XML file we need to update the file to ensure that is testing against the TestNGTodo1.java test file that we just tweaked.

Running the Tests

Open up Terminal and navigate the the project folder and run the command below to execute the test via maven.

Running TestNG Test via XML

mvn test -D suite=single.xml

Viewing Test Results

To monitor your test execution:

Go to the LambdaTest dashboard.
Navigate to Automation Web Automation .
Click on the executed test to view logs, screenshots, and videos of your test run.

Conclusion

Setting up LambdaTest for automated testing allows QA testers to execute tests on a scalable cloud infrastructure without maintaining a local Selenium Grid. In the next guide, we’ll show you Running Your First Test on LambdaTest to help you execute your first automated test successfully.
