BACKGROUND OF THE INVENTION:
Tremendous growth and development in internet based browsing technologies have made available to user, different web browsers and their respective versions. Such web browsers provide different functional and graphical user interface (GUI) support to a user. With the help of web browsers, the users have the access to different web based applications. However, the compatibility of the web applications differs from browser to browser and their respective versions of such browsers. The contents of the web applications such as text, still images and other GUI controls may be interpreted differently in different browsers. Hence, ensuring the compatibility of the web applications with the different versions of respective browsers, on the different operating system has become a challenging issue.
The process of validating the web applications and making them compatible with different browsers is tedious, time consuming and error prone process. In the prior art, various approaches have attempted for tes ting the compatibility of the web applications, but most of them are restricted either to limited browsers and their respective versions over limited platforms, such approaches also employ manual testing which is a time consuming process.
