Selenium Automated Testing With Jest Framework On Cloud

Developed by Facebook, Jest is a JavaScript testing library for React web-applications. With Jest automated testing framework, you can perform snapshot testing to help you comprehend the state of your react trees which are transforming over time. It provides an excellent combination of a test runner & an assertion library. You can make use of built-in code coverage reports for figuring out the areas the files that aren’t a part of your test code. There is also a built-in mocking library. Jest automated testing also works with Typescript.

Point your Jest WebDriver setup at the TestMu AI remote hub instead of a local driver, then pass your username and access key along with the browser, browser version and operating system you want in the desired capabilities. Your JavaScript project structure, step definitions and assertions stay exactly as they are - only the driver configuration changes.

Yes. Jest tests run in parallel across the cloud grid, and every test gets its own clean browser session so runs stay isolated. How many execute at the same time depends on the number of concurrent sessions in your plan, which is what turns a suite that takes hours locally into one that finishes in minutes.

Jest scripts run across 3000+ browsers and operating system combinations, including Chrome, Firefox, Safari, Edge and Opera on Windows and macOS, plus 10,000+ real mobile devices. You select the combination per test through desired capabilities, so a single Jest suite can cover many environments without duplicating code.

No. Existing Jest tests move across as they are - the same JavaScript code, the same reporting and the same CI setup. The only change is swapping the local WebDriver instance for a remote one that points at the TestMu AI hub, which is usually a few lines in your driver or configuration file.

Every Jest run is recorded, so you get a video of the session together with Selenium command logs, network logs and console logs. When a Jest assertion fails you can replay the exact session and read the command that broke, instead of trying to reproduce an intermittent failure on your own machine.
