"""A very basic test class derived from mox.MoxTestBase, used by mox_test.py.

The class defined in this module is used to test the features of
MoxTestBase and is not intended to be a standalone test.  It needs to
be in a separate module, because otherwise the tests in this class
(which should not all pass) would be executed as part of the
mox_test.py test suite.

See mox_test.MoxTestBaseTest for how this class is actually used.
