Serenity BDD LambdaTest Integration

LambdaTest is a cloud platform for test execution and test orchestration. With LambdaTest, Serenity users can extend their automation test coverage of their web and mobile apps on 3000+ real devices, browsers, and operating systems.

The serenity-lambdatest plugin provides seamless integration with the LambdaTest online test automation platform.

Adding the LambdaTest plugin#

To add the integrated support for LambdaTest to your project, you will need to add the serenity-lambdatest dependency to your project dependencies. For Maven, you would add the following:

    <dependency>        <groupId>net.serenity-bdd</groupId>        <artifactId>serenity-lambdatest</artifactId>        <version>${serenity.version}</version>    </dependency>

And for Gradle:

    testImplementation "net.serenity-bdd:serenity-lambdatest:${serenityVersion}"

Specifying your LambdaTest credentials and grid URL#

Next, you will need a LambdaTest account (If you don't already have one you can set up a free lifetime account to experiment).

You can add your LambdaTest credentials in two ways. The simplest is to define the following system properties:

  • LT_USERNAME - LambdaTest user name
  • LT_ACCESS_KEY- LambdaTest access key

Alternatively, you can define your username and accesskey using the lt.user and lt.key properties respectively in your serenity.conf file:


By default the standard LambdaTest grid URL ("") will be used to connect to the LambdaTest servers, but you can override this by setting the lt.grid property:

lt.grid = ""

Configuring the LambdaTest driver#

Serenity interacts with LambdaTest via the RemoteDriver driver. You can specify the remote URL explicitly, or let the serenity-lambdatest library do it for you. For example, to configure the URL explicitly you could use a serenity.conf configuration like this:

webdriver {  driver = remote  remote.url = "https://"${LT_USERNAME}":"${LT_ACCESS_KEY}""}

If the webdriver.remote.url property is not defined, Serenity will use these values to build one for you if the LambdaTest plugin is active (see below).

Activating the LambdaTest plugin#

The Serenity LambdaTest plugin will be invoked if Serenity can find a "LT:Options" section in your serenity.conf file, or if you specify a remote.webdriver.url that points to a LambdaTest server. If you have no LambdaTest-specific capabilities, simply set the property to true like this:

lambdatest {  active = true}

Defining LambdaTest Capabilities#

You can specify the operating system and browser you want to run your tests on by customising the Selenium Capabilities in your serenity.conf file. You do this in the "LT:Options" section of the serenity.conf file, e.g.

    webdriver {      driver = "remote"      capabilities {        browserName = "chrome"        version = "104.0"        platform = "Windows 10"        #        # Any LambdaTest-specific options go in the 'LT:Options' section        #        "LT:Options" {          resolution", "1280x800"          network = true // To enable network logs          visual = true // To enable step by step screenshot          video = true // To enable video recording          console = true // To capture console logs        }      }    }

Note that the w3c option will be set to true by default, as this is the default protocol for the Selenium version integrated with Serenity.

The LambdaTest test name will be assigned automatically. You can also set the build name by assigning the property. For example the following example shows how to create a build name from the Jenkins job name and build number environment variables:

lambdatest {  build = "${JOB_NAME} - build ${BUILD_NUMBER}"}

These properties will be placed in the LT:Options capability.


LambdaTest provides a convenient Capabilities Generator that gives an idea of what options are available.
