IETester (IET) : Cross Browser Compatibility Checker for Websites with Multiple Versions of IE

IETester is a free (both for personal and professional usage) WebBrowser that allows you to have the rendering and javascript engines of IE10 preview, IE9, IE8, IE7, IE 6 and IE5.5 on Windows 7, Vista and XP, as well as the installed IE in the same process.

IETester is a great tool for web designers and web masters. When you develop a website you have to test it for browser compatibility. With ie-tester you needn’t more computers with different versions of Microsoft IE installed. You can test your website in all versions of Internet Explorer (from 5.5 to 10) from one computer, without more installations.

[ Further Description ]

The differences in rendering a browser to another are often still a nightmare for web developers: how to ensure that a site is displayed correctly in Internet Explorer, Firefox or Opera? By testing, of course!

However, it is possible to install an older version of Firefox or Opera, but Internet Explorer is built into Windows and it is difficult, unless you use some “hacks” uncertain or virtualization, installing a 5.5 or 6.0 of Internet Explorer on a machine already gone to higher version!

IETester offers a very effective solution because it allows a site to test with the engine all versions (from 5.5 to 10) Internet Explorer, all in tabs that can display full-screen but also in mosaic (by dragging and dropping the tab in the main window).

We are unable to have a “real” version of IE 5.5 for testing, and it is unclear whether the report is accurate, but it seems consistent.

[ Known problems and limitations ]

• The Previous/Next buttons are not working properly
• Focus is not working properly
• Java applets are not working

[ System Requirements ]

Windows 7, Windows Vista or Windows XP with IE7 minimum (Windows XP/IE6 config has some problems and IE8 instance do not work under XP without IE7)

[ Note for IE10 ]

IETester installer does not include IE10 files, so you will need to install IE10 preview and copy files manually : See How To install IE10 under IETester (IE10 Preview requires Windows 7).
