Testing
The standard for automating native iOS and Android apps when your tests need to leave the browser entirely.
Skip maintaining your own device lab — thousands of real browsers and phones on tap for cross-platform testing.
Runs inside the browser itself, so debugging a flaky end-to-end test feels like debugging, not guessing.
The default unit-test runner for JS and React — zero-config, snapshot testing, and everyone already knows it.
Microsoft-backed, genuinely cross-browser, and fast enough that teams migrating off Selenium rarely look back.
The granddaddy of browser automation — clunkier than newer tools, but still what most enterprise QA stacks run on.
Jest's API without Jest's slowness — if your app already runs on Vite, this is the obvious unit-test pick.
