Software Developers: How do you test your programs on multiple platforms?
 

I'm trying to test an app I had built on multiple platforms (Vista, XP, XP SP/2) and with multiple browsers (IE 6, IE 7, FF, etc.). Anyone have a suggestion on how to do multiple platform testing easily other than getting 3-4 computers setup to do individual tests? This is an IE/FF plugin and its hard enough testing multiple browsers on the same machine (like IE6 and 7), let alone multiple platforms. Anyone have suggestions on how to do testing of something like this without needing 3-4 machines?

Thanks

ask other people to do it for u?

Its not really ready for public testing, its been very buggy on XP (XP SP/2 is fine though), and I don't have an uninstaller setup yet. I don't want to irritate people because I know it still is buggy. Its the core features I need to test so having others help out is kind of out for now.

I guess you can have 1 pc and setup a few users on it, then install a different browser for every user.

Its fine for 1 version of IE and firefox. But I also need to test on different OS' like Vista and XP.

Partitions.

crossbrowsertesting.com, browsercam.com, etc. or your own virtual OS images. (as fallenmuffin implied...)

Install FireFox
Install Safari for windows

and also

Get Virtual Machine software, where you can setup virtual operating systems that you own on them so you can test in safe environments using hard drive space and system ram.

vmware should be able to do that for you:

Ive used it to test linux distros (briefly :upsidedow) and you can use diff versions of same products. Hope that helps!
