I have found on the Software Testing Magazine web site this interesting video that provides some tips to write better Selenium tests. Selenium is a suite of tools to automate web browsers across many platforms.
* 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.
