Selenium Web Driver

Web Driver is just a JAR file which contains collection of interface and class.

Web Driver is a web based automation testing tool which uses core Java API to drive the test on the browser. Technically Web Driver is an interface , all the browsers driver classes are implemented as Web Driver interface and also many other interfaces.

It is a new version of Selenium which removes many drawbacks and issues in Selenium RC. Web Driver as native supports all the browsers and all the APIs of Web Driver are purely object oriented.

Web Driver supports multiple browsers. For Web Driver it doesn't matter whether their is already opened browser, it launches a new browser for each execution.

Whenever Web Driver launches all the add-ons are automatically get disabled.
