ajaxUnit is a way of unit-testing AJAX apps that are written in PHP & Javascript.
The test software can put your app in a predetermined state then compare the responseText from the XMLHttpRequest object with what you are expecting.
You can define a series of tests that run automatically. The test flow can be determined by the results of previous tests.
All you need to run the tests is a function call to ajaxUnit in the onreadystatechange callback function. You need to include the ajaxUnit.js in each page where you want to run the tests.
