I just found a nice tool to have several internet explorer versions running in parallel: the Internet Explorer Collection.

Do you feel like testing your site under Internet Explorer 1 ? Right, you don’t. But with this tool, you can – up to IE9. The Internet Explorer Collection runs on all recent Windows platforms, so for the Mac users, use a virtual machine like Parallels or VMWare to have a virtual windows installation, on top of which you can install the IE Collection.

Here is the setup screen which shows the various versions of Internet Explorer provided by this handy testing tool.

If you have any other tools you’d like to share, let me know in the comments.

In the meanwhile… Happy testing !
