Testem is a JavaScript test runner that executes tests in real desktop browsers (Chrome, Firefox, Safari, Edge), Node, or custom launchers. It is framework-agnostic, supporting Jasmine, QUnit, Mocha, and custom adapters, with workflows for both TDD and CI.

Use cases

  • run javascript unit tests in real browsers
  • test runner for mocha jasmine qunit
  • run browser tests in ci pipeline
  • tdd workflow for javascript
  • headless chrome test runs
  • run tests across chrome firefox safari edge

When to choose

  • you need tests running in real browser engines rather than simulated DOM environments
  • you want a framework-agnostic runner supporting multiple test frameworks
  • you need both interactive TDD mode and CI integration with GitHub Actions or Jenkins

When to avoid

  • your project is not JavaScript/Node-based
  • you only need Node-only tests without browser execution
  • you prefer an all-in-one framework that prescribes its own testing style
