After Ray mentioned the CFUnit Testing Components from the DRK today in our development meeting, we got around to talking about automated testing of websites. David mentioned httpunit as one option (you can see a couple examples of how it might be used here). Looks like Cactus might also be an option, althought it appears to be Java specific and aimed more at the testing of the components of a website (EJBs, Taglibs, Servlets) rather than the end result (HTML). Does anyone have any experience with these tools? Do you use other tools?
