The test case functionality also needs to be written, of course. At some
point you need to get concrete about what to do in the system under
test, and what assertion you want to make :-)

    def test_some_specific_condition(parameter_foo, parameter_bar):
        sut.do_something_with(parameter_foo)
        self.assertSomeThing(parameter_bar)

Once you have functions written that do the tests given a set of
parameters, you can then parameterise those test functions to generate
test cases.
