Really cool tool selenium. Visit http://seleniumhq.org for introduction.
Selenium is an open source tool for web application testing. This tool is primarily developed in Java Script and browser technologies and hence supports all the major browsers on all the platforms. For example, you can have your automation scripts written for Firefox on Windows and run them on Firefox in Mac. Most of the time, you will not need to change your scripts for them to work on Mac. In terms of coverage for platform and browser, Selenium is probably one of the best tool available in the market for web applications. There are three variants of Selenium, which can be used in isolation or in combination to create complete automation suite for your web applications.
- Selenium IDE
- Selenium Core
- Selenium Remote Control tool.
