At some point in the future, the way that all major browsers render Web code will likely be standardized, which will make testing across multiple browsers no longer necessary as long as the website is coded according to Web standards. But because that day is still a way off (if it will really come at all), testing your design the advanced browsers as well as legacy browsers is a necessary part of any project.
The old-school way to test code was to load your website on as many computers as you could find, using as many different combinations of browsers and operating systems as possible. That was fine if you had access to a bunch of different computers (and had some time to kill). But there are much more efficient ways to test across browsers, using either free or commercial Web services and software. In this article we review some of the most useful ones.
