Selenium testing tool

Selenium is an open source suite of tools that automate web application testing across many platforms. Basically, in simple words it is a web site testing and automation platform. Considered as a GUI based automation tool, it beckons several browsers on varied platforms. In my opinion, it is a platform, as it can’t really be justified as simple a tool, language, any full application or API, rather regarded as all of these. Selenium actions and accessors are the language you program your scripts in. In addition, Selenium scripts comprise a table constituted with three columns. Amongst them, the first column is the action to perform, second is like the first argument of function and third one is like the second argument in a function.
