Thanks for the feedback :-D

Changes:

Utilize test.support.temp_cwd()
Removed imports that this made unnecessary
 Awesome trick!

Cut line length down. Don't worry about nitpicking. Anything to get this to be as good as possible.

I added an explanation to the test class explaining why test_getting_all_methods_from_class does not appear. I also agree this is fragile. I have an idea for how to fix this and will upload it as a separate patch (in this thread) because I am not sure what people will think.
