npm Plugin For TestCafe Integration With TestMu AI

TestCafe offers a comprehensive and extensive platform to perform end-to-end tests for node.js applications. It supports both JavaScript and Typescript so that you can write tests in either one of the two. With TestCafe, you can create stable tests that are easy to integrate with your continuous integration process. You can also execute multiple test cases in parallel.

TestMu AI, a cloud-based, cross browser testing platform, is out with an npm plugin that would allow you to integrate TestCafe with your TestMu AI account. That way, you can expand your test coverage using TestMu AI Selenium Grid on 3000+ real browsers and browser versions running across various operating systems for mobile, desktop, and tablets. Similar to TestCafe, TestMu AI Selenium Grid also allows you to perform parallel testing.

How To Use npm Plugin For TestMu AI & TestCafe Integration?

To acknowledge all available browsers aliases offered by TestMu AI Selenium Grid, type the below command:

testcafe -b lambdatest

To execute the test from cmd/terminal by declaring the browsers and operating systems to test:

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

For Parallel testing:

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

If you are using API, then you need to declare the aliases inside your browser() method:

testCafe
    .createRunner()
    .src('path/to/test/file.js')
    .browsers('lambdatest:Chrome@74.0:Windows 8')
    .run();
