    npm Plugin For TestCafe Integration With LambdaTest

    Build Status

    This plugin integrates TestCafe with the LambdaTest Testing Cloud.


    $ npm install testcafe-browser-provider-lambdatest


    Before using this plugin, save the LambdaTest username and access key to environment variables LT_USERNAME and LT_ACCESS_KEY, as described in LambdaTest Documentation.

    You can determine the available browser aliases by running

    $ testcafe -b lambdatest

    If you run tests from the command line, use the browser alias when specifying browsers: For Single Configuration

    $ testcafe "lambdatest:Chrome@74.0:Windows 8" "path/to/test/file.js"

    For Parallel/Multiple Configuration

    $ testcafe "lambdatest:Chrome@74.0:Windows 8","lambdatest:Chrome@75.0:Windows 10" "path/to/test/file.js"

    When you use API, pass the alias to the browsers() method:

        .browsers('lambdatest:Chrome@74.0:Windows 8')
