When should I use Karma?

You want to test code in real* browsers.
* You want to test code in multiple browsers (desktop, mobile,
tablets, etc.).
* You want to execute your tests locally during development.
* You want to execute your tests on a continuous integration server.
* You want to execute your tests on every save.
* You love your terminal.
* You don't want your (testing) life to suck.
* You want to use [Istanbul] to automagically generate coverage
reports.
* You want to use [RequireJS] for your source files.

But I still want to use \_insert testing library\_

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. There are already plugins for most of the common testing frameworks:

* [Jasmine]
* [Mocha]
* [QUnit]
* and many others

If you can't find an adapter for your favourite framework, don't worry and write your own.
It's not that hard and we are here to help.

Why did you create this?

Throughout the development of [AngularJS], we've been using [JSTD] for
testing. I really think that JSTD is a great idea. Unfortunately, we
had many problems with JSTD, so we decided to write our own test
runner based on the same idea. We wanted a simple tool just for
executing JavaScript tests that is both stable and fast. That's why we
use the awesome [Socket.io] library and [Node.js].

My boss wants a license. So where is it?
