Testing your WordPress theme across different browsers can be a daunting task. You may have the latest versions of most of the most-used browsers on your computer, however it is worth testing previous versions too.
Traditionally you would have to use a different installation of an operating system on a virtual machine or another computer in order to test; these were inconvenient methods. There are now other methods to test different browsers effortlessly.
In recent years there have been web-based services set up to let developers and designers do cross-browser testing quickly and efficiently. Some of these services are effectively screenshots of your website across different browsers, however some others work like virtual machines.
These services are generally free, however some will offer a paid membership which will guarantee you a quicker and better service. Below are some of the free services.
Adobe Browserlab (Free)
Browserlab is a free service provided by Adobe that allows users to live-test their website on various modern and old browsers and across Windows and Mac OS. Browserlab works like a virtual machine. A split-screen mode is available so that users can compare their website on different browsers. The list of available browsers are however limited only to the latest version of Chrome, Firefox (on both Windows and Mac OS), Safari, and the four latest versions of Internet Explorer.
On average it took around 20 seconds to load the WPMU.org homepage.
Browsershots (Free & paid)
Browsershots takes screenshots of your website and allows you to download medium-sized images of the results. The results, however, only show the top portion of the website depending on the preset resolution size of the browser. The list of available browsers is enormous (164 versions of browsers across three operating systems) and even includes the little-used and little-known ones like Avant and Flock.
Browsershots provides both a free and paid service, however the free service is quite slow and there’s a limit on how many screenshots you can request in a day. The paid version is $29.95 or €23.95 per month and is much quicker, you will be able to get 30 to 50 screenshots in two to five minutes.
Requesting screenshots from the four latest IE browsers took 15 minutes on average.
