Selenium

Web Application Testing System

Selenium IDE is a Firefox add-on that records clicks, typing, and other actions to make a test, which you can play back in the browser.

Selenium Remote Control (RC) runs your tests in multiple browsers and platforms. Tweak your tests in your preferred language.

Selenium Grid extends Selenium RC to distribute your tests across multiple servers, saving you time by running tests in parallel.
