With the availability of a wide range of web browsers, the end-users are using a great variety of web browsers to access the web applications. Thus, it has now become crucial to test web applications on multiple browsers. The client components like JavaScript, AJAX requests, Applets, Flash, Flex etc. may behave differently on different browsers. Also, the process of request handling for different browsers also varies.

Cross-browser testing is necessary to ensure that your web application or website is performing accurately on all the browsers due to the fact that browsers have a different method of presenting the site, in which case differences and errors might occur in the layout, feature or functionality. Cross Browser Testing is a process that allows the testing of web applications across multiple browsers. It involves checking the compatibility of your application across multiple web browsers. Cross-Browser testing involves testing both the client-side and server-side behaviour of the Web application when it is accessed using different Web Browsers.
