Selenium the Agile automation testing tool

Test automation is usually lagging behind development of new functionality. The tools that are used to automate are dependent on the UI and this causes automation of the functionality to start only after the environment and the UI are stable.

Selenium is the test automation tool that helps test below the UI layer. The automation can be done earlier even before the UI is completely ready or matured.

Selenium is language independent and this makes to unique as testers/ developers can start coding as they code the application. You can code the Selenium automation scripts in PHP, Java, C#, Ruby, Python. Selenium uses locator – an element locator on a webpage to identify the element on the webpage.

Ideally its good to code the test scripts in the language the web application is built; by doing so you can integrate the test scripts in your nightly build and help speed up the QA process.
