Karma is a node-based test tool that allows you to test your JavaScript codes across multiple real browsers. A node-based tool is any tool that needs the Nodejs engine installed for it to run and can be accessed (installed) through the node package manager (npm). Karma is a tool that makes our test-driven development fast, fun and easy. It is technically termed as a test-runner. It is noteworthy to mention here that Karma was developed by the Angular team. Karma is not a testing framework, nor an assertion library. Karma just launches an HTTP server, and generates the test runner HTML file you probably already know from your favourite testing framework. So for testing purposes you can use pretty much anything you like.
