I'm not clear on why this is a metaclass rather than a simple class decorator.

Because I didn't think of it. I don't (yet) think of "class" and "decorator" in the same sentence :)

Your description doesn't match your examples or implementation. Assuming the example and implementation are correct (and they look more sensible than the currently described approach), I believe that last sentence should be:

"The full name of a generated test is a 'test_' prefix, the portion of the test function name after the '_as_' separator, plus an '_', plus the name derived as explained above."

Oops, yes. Thanks for the catch. --David
