 These methods are used instead of the :keyword:`assert` statement so the test
 runner can accumulate all test results and produce a report.

 When a :meth:`~TestCase.setUp` method is defined, the test runner will run that
 method prior to each test.  Likewise, if a :meth:`~TestCase.tearDown` method is
 defined, the test runner will invoke that method after each test.  In the
