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

    18 

    19 The class defined in this module is used to test the features of

    20 MoxTestBase and is not intended to be a standalone test.  It needs to

    21 be in a separate module, because otherwise the tests in this class

    22 (which should not all pass) would be executed as part of the

    23 mox_test.py test suite.

    24 

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