Hello again everyone - and thanks for your responses. Adding the
unittest method message was something I didn't realize I could do!

I think you make a good argument for simple testing ... and I already
fell victim to "It's working great! My tests pass!" when in fact the
test wasn't working at all!
Here is what I ended up doing, and it (currently) runs 52 tests.
I'm not sure if it is worth the trade-off, but I think it saved me
some typing (and makes it easy to add another file or tag key/value
pair).

setattr(cls, test_name, new_test)
for file in FILES:
for key, value in TAG_VALUES:
