| [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. |

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