LambdaTest Integration

Estimated reading time: 3 minutes

The LambdaTest integration will help you run your automation scripts on LambdaTest Selenium Grid from your Katalon Studio instance. To integrate with LambdaTest, you will need to execute your test scripts using the Remote option based on LambdaTest’s provided capabilities of your choice.

Here is a step-by-step guide to help you trigger your first automation script on LambdaTest Selenium Grid through Katalon Studio.

Step 1: Log in to your LambdaTest account.

Step 2: In the left-navigation menu inside LambdaTest web application, go to the Profile tab, then enter your Username and Access Key.

These values are necessary for authentication purpose between your Katalon Studio instance and LambdaTest account. They will also help generate a secure remote connection between Katalon Studio and LambdaTest remote hub URL.

Syntax for LambdaTest remote URL:

The above image is an example of a LambdaTest Profile section. This would help you to realize the syntax for invoking a LambdaTest remote URL. In this case, the remote URL is:

Step 3: Now, you need to specify your desired capabilities to execute your test automation script. To do so, the LambdaTest Capabilities Generator will provide the desired capabilities the class to run scripts in LambdaTest Selenium Grid.

LambdaTest Capabilities Generator supports various programming languages for your desired capabilities class:

  • Java
  • C#
  • PHP
  • Ruby
  • JavaScript
  • Python

For example, you want to test on macOS Mojave using the Google Chrome browser version 75 on a screen resolution of 1024x768. Then the Capability Generator will provide you with the desired capabilities class below for Java frameworks.

Step 4: Once you have your desired capabilities set, the next step is to configure the Remote settings in Katalon Studio. Go to Project > Settings > Desired Capabilities > Remote.

Step 5: Enter the basic parameters for your automation tests and execute it. Go to Action > Run > Remote.

Important Note: LambdaTest recommends using Listeners to avoid timeout issues while executing Groovy scripts in LambdaTest Selenium Grid from Katalon Studio. Below is an example of a Listener.

Step 1: Select Test explorer from the left navigation menu in Katalon Studio > Right click the Test Listener folder > Click New listener.

Step 2: Provide a relevant name to the new listener before pasting the code below:

	def sampleAfterTestSuite(TestSuiteContext testSuiteContext) {
		println testSuiteContext.getTestSuiteId()
