Go Test It

Go Test It provides automated cross-browser testing for web applications. Yes we have to test cross-browser testing

Go Test It enables web application developers and QA teams to quickly and easily create functional tests which check if an application is behaving correctly. Tests simulate the behaviour of a user interacting with the site, with full support for JavaScript and Ajax. These tests can be played back automatically in a wide range of web browsers, and site owners are notified if any feature of the site is not working as expected.
