Instructions to setup selenium 2.

Selenium 2.0 and WebDriver

WebDriver is a tool for automating testing web applications, and in particular to verify that they work as expected. It aims to provide a friendly API that’s easy to explore and understand, which will help make your tests easier to read and maintain. It’s not tied to any particular test framework, so it can be used equally well with JUnit, TestNG or from a plain old “main” method. This “Getting Started” guide introduces you to WebDriver’s Java API and helps get you started becoming familiar with it.

Start by Downloadingthe latest binaries and unpack them into a directory. From now on, we’ll refer to that as $WEBDRIVER_HOME. Now, open your favourite IDE and:

* Start a new Java project in your favourite IDE
* Add all the JAR files under $WEBDRIVER_HOME to the CLASSPATH

You can see that WebDriver acts just as a normal Java library does: it’s entirely self-contained, and you don’t need to remember to start any additional processes or run any installers before using it.
