Selenium

Selenium is a web application test automation tool which provides many features and a wide

range of support which makes it an instant choice for automating most of the web applications.

Selenium provides the automation engineer the choice of running the automation scripts in a

wide range of browsers and with the language support it has, on wide range of operating systems too.

But there are certain things the automation engineer needs to be aware of before he jumps into understanding selenium. The automation engineer needs to have a basic knowledge of the following things:

1. HTML

2. XML

3. Xpath

4. Document Object Model(DOM)

5. JavaScript (only a basic knowledge on how events are triggered etc.)

6. Any one of the following language to build a full-fledged test suite – Perl, Python, Ruby,

Java, C#, PHP.

7. Basic object oriented programming concepts.
