Cross browser, cross operating system testing is a costly and tedious task. Most often we test our web application on the Internet Explorer and Fire Fox installed on our machine and hope for the best. In big projects with rigid compliance requirements we test the major operating systems (Apple, Windows and sometimes a popular Linux distribution) with the major Browsers. The underline assumption is that this covers 99.x% of the population and we are happy with that. But what if we could, without additional cost, see how our web site looks like in many operating systems and multiple browsers?
