-[QUnit](http://docs.jquery.com/QUnit) - A JavaScript Unit Testing framework.
-================================
-
-QUnit is a powerful, easy-to-use, JavaScript test suite. It's used by the jQuery
-project to test its code and plugins but is capable of testing any generic
-JavaScript code (and even capable of testing JavaScript code on the server-side).
-
-QUnit is especially useful for regression testing: Whenever a bug is reported,
-write a test that asserts the existence of that particular bug. Then fix it and
-commit both. Every time you work on the code again, run the tests. If the bug
-comes up again - a regression - you'll spot it immediately and know how to fix
-it, because you know what code you just changed.
-
-Having good unit test coverage makes safe refactoring easy and cheap. You can
-run the tests after each small refactoring step and always know what change
-broke something.
-
-QUnit is similar to other unit testing frameworks like JUnit, but makes use of
-the features JavaScript provides and helps with testing code in the browser, eg.
-with it's stop/start facilities for testing asynchronous code.
-
-If you are interested in helping developing QUnit, you are in the right place.

-Planning for a qunitjs.com site and other testing tools related work now happens
