QUnit: A JavaScript Unit Testing framework.

What is QUnit?

QUnit is a powerful, easy-to-use JavaScript unit testing framework. 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:

	
					<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title>QUnit Example</title>
  <link rel="stylesheet" href="https://code.jquery.com/qunit/qunit-2.0.1.css">
</head>
<body>
  <div id="qunit"></div>
  <div id="qunit-fixture"></div>
  <script src="https://code.jquery.com/qunit/qunit-2.0.1.js"></script>
  <script src="tests.js"></script>
</body>
</html>

The contents of tests.js:

	
					QUnit.test( "hello test", function( assert ) {
  assert.ok( 1 == "1", "Passed!" );
});

The result:

Browser Support

QUnit currently supports the same browsers as jQuery 3.x.

For legacy browser support, including Internet Explorer versions lower than IE9, please use the 1.x series of QUnit.

QUnit is available from the jQuery CDN hosted by MaxCDN.

Current Release - v2.0.1

To test the latest features and bug fixes to QUnit, a version automatically generated from the latest commit to the QUnit Git repository is also available for use.

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.
