Mark, do you mean testing an entire application after modules have been recorded? If so, then no, ACT doesn't really have that feature as a strong point. In the (short) time I've been playing with it, it seems that ACT is geared towards programmers who use it for unit testing rather than testing the whole application from a user's standpoint.
Right now it seems that unless you record all the possible features of your application in one session, there won't be a way to get good functional testing done. I'm currently trying to find a way to set up a queue for unit tests that could act as a functional test. However, this requires taking off the QA hat and putting the programmer's one on.
Please respond back and maybe we can get a discussion going on this. I have seen very little in the way of usable documentation for ACT.
It's my contention that ACT is an underdeveloped one-dot-oh baby. Yea, you can record and playback stuff at the HTTP layer but forget it for much else.
I've gotten it to run a bit of VB Script that works in QuickTest Pro but it's just as easy to double-click on the .vbs file in Explorer.
And how are you supposed to run a bunch of scripts sequentially or as a set?
I do hope that the developers at MS don't think this is a decent functional testing tool. They used to use a lot of VT and some Robot too but I have no idea what they've been using lately. I hope they're not trying to use ACT. That would be really sad.
