Karma is a JavaScript test runner that executes tests in multiple real browsers, originally built to make test-driven development easy and fast. It is now officially deprecated and only receives critical security fixes, with Jest, Vitest, Web Test Runner, and jasmine-browser-runner suggested as alternatives.
Use cases
- run unit tests in real browsers
- set up test-driven development for JavaScript
- test Angular applications in a browser
- run tests across multiple browsers automatically
- integrate browser-based testing into CI
When to choose
- maintaining an existing legacy Karma setup, especially Angular projects not yet migrated
- you need a battle-tested browser test runner for an older codebase
When to avoid
- starting a new JavaScript or Angular project
- you want an actively maintained tool with modern performance
- you prefer Node-based testing with Jest or Vitest
