Karma is a powerful test runner for JavaScript that allows you to run tests in real browsers or headless browsers. It provides a flexible and configurable environment for testing your code across different browsers and platforms. Karma integrates seamlessly with popular testing frameworks like Jasmine, Mocha, and QUnit, making it easy to write and execute tests.
Compared to alternatives like Jest or Mocha, Karma is more focused on providing a robust test running environment rather than built-in assertion libraries. It excels in running tests in actual browsers, which is crucial for ensuring cross-browser compatibility and accurate testing results.
