Selenium is a web application testing framework that allows you to write tests in many programming languages like Java, C#, Groovy, Perl, PHP, Python and Ruby. Selenium deploys on Windows, Linux, and MAC OS.
It is an open-source project, released under the Apache 2.0 license, so you can download and use it without charge.
2.Selenium RC (aka Selenium Remote Control or Selenium 1) receives Selenium Core commands via HTTP and executes them on a remote machine, proxying the web browser in order to avoid the “same host origin” restriction. This also allows writing the tests in other languages like C#, Python, Perl, PHP, Java and Ruby (via language bindings for Selenium Core).
4.Selenium Server allows using Selenium-WebDriver on a remote machine.
5.Selenium IDE is a Firefox add-on that records user activity and creates a test case based on it. It can also play the tests back and save them as a program in different languages.
6.Selenium-Grid allows you run the tests on different machines against different browsers in parallel; in other words it enables distributed test execution.
7.Selenese is a special “language” represented by a set of Selenium commands that run your tests. A sequence of these commands is called a test script.
Selenium WebDriver supports many more powerful features which are not supported in the primitive Selenium rc 1.x. Learning curve for Selenium Web Driver is less, as you don’t need to have knowledge of Selenium RC and you can directly start working on WebDriver. One advantage over Selenium testing on RC is that you don’t need to start the server prior to executing test scripts. The goal of the WebDriver’s to provide a well-designed object-oriented API which gives you the enhanced hold up for modern advanced web-app testing problems
