In the past I've used WWW::Mechanize (along with HTTP::Recorder to create basic tests). When I've had to drive IE I've used Win32::IE::Mechanize. Corion recently released WWW::Mechanize::Firefox which is worth looking at.

Many people are these days people are using things like Selenium to test web based apps. See Using WWW::Selenium To Test Or Automate An Ajax Website from the tutorials section.

I've never used Win32::IEAutomation, and doubt that I ever will.

Update: Fixed typo tutoruals/tutorials

Thanks, I had a quick look and they all seems to be about the same stuff and can be used I guess in combination. Whatever works, right?

So, do you think QTP and similar tools could be completely replaced by using perl with these modules?

I've never used QuickTest Professional, or any of the other HP testing tools, so I can't offer a comparison. Selenium seems to be a reasonable offering, though perhaps overkill depending on exactly what you want to test.

Don't believe I've ever used Win32::IEAutomation (and I confess I don't know what QTP is), but you may wish to have a look at Using WWW::Selenium To Test Or Automate An Ajax Website.

What is the difference?
