Selenium

Selenium IDE

Selenium IDE is a Firefox add-on that makes it easy to record and playback tests in Firefox 2+. You can even use it generate code to run the tests with Selenium Remote Control.

Selenium Remote Control

Selenium Remote Control is a client/server system that allows you to control web browsers locally or on other computers, using almost any programming language and testing framework.

Selenium Grid

Selenium Grid takes Selenium Remote Control to another level by running tests on many servers at the same time, cutting down on the time it takes to test multiple browsers or operating systems.

Selenium Core

Selenium Core is the original Javascript-based testing system. It's now used primarily as a component of Selenium Remote Control, but it can also be used as a pure Javascript/HTML testing system.

Selenium on Rails

Selenium on Rails provides an easy way to test Rails application with Selenium Core. Suite files are created on the fly for each directory and the Selenium Core files don't have to pollute /public.

Selenium on Ruby

Selenium on Ruby is the hub for newer Ruby related Selenium projects.

CubicTest (for Eclipse)

CubicTest is a graphical Eclipse plug-in for writing Selenium and Watir tests. It makes web tests faster and easier to write, and provides abstractions to make tests more robust and reusable.
