Thanks everyone!
I gave up on sys.argv and opted to not try to import my module into my test
script, so not trying to change the options after the fact, so as to speak.
Now I am just running the python script using the os.system call from the
unittest, and that is working. It is going to take a while to figure out
the best way in general to run unit tests on this code. I like Matt's
suggestion of just importing what I need from their code to run a
particular test, but that could get pretty complicated. But, heh, I'm
making VR games in python, so it's all good!
cheers,
Maria
