Questions tagged [karma-runner]

Karma provides developers a testing environment where they don't have to set up many things, rather just write code and get instant feedback in order to improve productivity and creativity.

Basic functionality

For all browsers connected to Karma's web server, source code is executed directly against test code. Developers receive the results of the tests on the command line with the ability to see which tests passed or failed for each browser.

Notice that Karma is only a test-runner, meaning it does not do testing itself. It runs tests implemented in some other test framework (e.g. Jasmine, QUnit, or Mocha).

Features

  • It can launch and run the test through real browsers.
  • It monitors file update on disk, and can instantly re-run required test giving very quick feedback on changes.
