Test Multiple Versions of IE on the Same System with IETester

0

The alpha version of IETester was recently released and “IETester is a free WebBrowser that allows you to have the rendering and javascript engines of IE8 beta 1, IE7 IE 6 and IE5.5 on Vista and XP” on the same machine.


To good to be true? No, not if you take that sentence literally. These kinds of tools can indeed help you test for “rendering/layout” and “JavaScript” issues, but tend to quickly fall apart when it comes to integration with the OS shell (plug-ins, caching, cookies, modal dialogues, printing etc). IETester is much like MultipleIEs, these types of tools can help when you’re in a bind and want to validate something simple that is script or layout related. But to use these tools to conduct all your browser testing versus your dedicated IE systems or VMs will likely bite you in the long run when the issues go beyond layout or JavaScript. IMHO these tools are best left in the hands of the developers to quickly validate layout issues and then QA can follow up with the real thing. It’s a good tool to have around but don’t bank on it! 🙂
