QUnit is a JavaScript unit testing framework. Originally developed for testing jQuery, jQuery UI and jQuery Mobile, it is a generic framework for testing any JavaScript code.
It supports client-side environments in web browsers, and server-side. As of now the current release of QUnitjs is v2.9.2.
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.
You cna install Qunitjs by using any of below command in your local machine to test JS features.
Below are some examples of QUnitjs testing framework.
