The method must begin with 'test' in order to be found as a test by
Trial's test loader. This is the same as what unittest.TestLoader

Twisted's internal convention is that methods intended to be found
dynamically should have the form '<prefix>_<camelCase>'. Sometimes we
are not so good at following our conventions.
