QUnit: A JavaScript Unit Testing framework.

What is QUnit?

QUnit is a powerful, easy-to-use JavaScript unit test suite. It's used by the jQuery, jQuery UI and jQuery Mobile projects and is capable of testing any generic JavaScript code, including itself!

Getting Started

A minimal QUnit test setup:

<meta charset="utf-8">

<title>QUnit Example</title>

<link rel="stylesheet" class="/resources/qunit.css">

</head>

<body>

<div id="qunit"></div>

<script src="/img/spacer.gif"> script>

History

QUnit was originally developed by John Resig as part of jQuery. In 2008 it got its own home, name and API documentation, allowing others to use it for their unit testing as well. At the time it still depended on jQuery. A rewrite in 2009 fixed that, and now QUnit runs completely standalone.

QUnit's assertion methods follow the CommonJS Unit Testing specification, which was to some degree influenced by QUnit.
