    Each instance of :class:`TestCase` will run a single base method: the method
-   named *methodName*.  However, the standard implementation of the default
-   *methodName*, ``runTest()``, will run every method starting with ``test``
-   as an individual test, and count successes and failures accordingly.

    the *methodName* nor reimplement the default ``runTest()`` method.
