QUnit is a unit TESTING framework for JavaScript programming LANGUAGE. It is important in the test driven development, and is used by jQuery, jQuery UI, and jQuery Mobile projects. QUnit is capable of testing any generic JavaScript codebase.

QUnit promotes the idea of "first testing then coding", which EMPHASIZES on SETTING up the test data for a piece of code, which can be tested first and then implemented. This approach is like "test a little, code a little, test a little, code a little..." which increases the programmer’s productivity and the stability of program code reducing the programmer’s stress and the time spent on DEBUGGING.
