Karma is a tool for testing client-side JavaScript. Karma executes tests against your application running in a real browser, which ensures correctness and trustworthiness of test results. IntelliJ IDEA integrates with Karma so you can run, debug, and monitor coverage of your tests from inside the IDE. You can see the test results in a treeview and easily navigate to the test source from there. Test status is shown next to the test in the editor with an option to quickly run it or debug it.
