jquery.ajaxmock (bower): jQuery.ajaxMock is a tiny yet powerful mocking plugin for jQuery 1.5+Just register a fake response  (the mock object) . All subsequent $.ajax calls to registered urls will be incercepted, and their're callbacks will recieve the faked response. Keep in mind that no real XHRrequests will be made. Works like a charm with Jasmine (http://pivotal.github.com/jasmine/) the a behavior-driven development framework for testing JavaScript code.
