cxtest popped up in a /. interview with someone from Crossover Office a while back, and I duly recorded it as something to try. I just checked it out from CVS, built it, and tried it out. Their README instructions worked perfectly, despite their dire prognostications, and I got a recorded script of me testing out xmessage.
Very cool.
I wonder how well it scales? I will have to try it out with my (so far untestable) GUI... Combined with Web testing a la twill and C++ and Python code coverage analysis, I may finally have a soup-to-nuts testing setup available for my application suite.
