Javascript unit testing frameworks

Myself and Simone have been in discussions about creating a jQuery plugin for many months now.  With real life, time on both parts hasn’t been on our side. Simone has co-authored a MVC book entitled “Beginning ASP.NET MVC”. I’ve been busy with work, getting fit, holidays, and other projects (more details coming soon).

We’ve both now managed to make a start on the plugin which resulted in me looking at unit testing frameworks for JavaScript. I was quite surprised to find the amount I did hence this short and sweet post.

List of JavaScript testing frameworks

• QUnit – jQuery testrunner – http://docs.jquery.com/QUnit
• JsUnit – port of JUnit to JavaScript – http://www.jsunit.net/
• JsUnitTest – http://jsunittest.com/
• Yahoo UI library – YUI Test – http://developer.yahoo.com/yui/yuitest/
• UnitJS – http://www.codeproject.com/KB/scripting/UnitJS.aspx

With the project being jQuery orientated we’re going to use QUnit for our testing needs.  As a personal learning curve I am going to play about with YUI test suite and JsUnit framework on some other projects. I would like to compare the differences, advantages and disadvantages to using each one.
