We are thinking along some of the same lines. Most likely I'll have to create any tool that I use. I was hoping someone would have thought of that already. > But what I would usually suggest is extensive logging.
I've created a quick class that logs an event every time a member function is called, and that works well for seeing what paths the program took on any particular run, but it doesn't allow me to force certain paths to be taken. It is really useful for gaining an understanding of what my code is actually doing, and it's helped me optimize something. > > I was thinking there should be a way to control a program's threads > > from the outside and write a script to test every path, but I don't > > know if that's possible. > > I don't know of any such tool, but I'd be quite interested to > know if there > is one. I am thinking of writing a program that creates a set of events (one for each thread in my app), and has a button that triggers that event. Then I would sprinkle WaitForSingleEvent() calls all over my code. Then my program would be a "puppet" of the other one and the threads would run in a completely deterministic order. That would catch some race conditions, but it would miss those that happen between my WaitForSingleEvent() calls. I would want to create a set of scripts for the controller program that test every combination. There are some technical things to worry about, like the threads are created and destroyed on the fly, so the controller would have to know about new ones. In any case, it sounds like a lot of work, and possibly not very thorough. I was hoping someone had gone down this path before.
