I tried a fun little experiment. I played a script in Selenium whilst recording in QEngine. Much to my surprise, it worked! Sure, none of the verification functions in Selenium(VerifyTextPresent, etc) obviously didn't port over, but the web actions surely did. After jumping through some hoops in QEngine for it to work in FireFox 2.0x, I put Selenium to its slowest speed & let 'er run.

So for quick & crude automated script conversion, you can at least get the active commands(navigating pages, submitting forms, etc) & port the verification & check commands yourself. I setup a cheat-sheet among the 2 apps for EZ conversion.

I'm curious how the other automated r/p tools interact with each other.
