    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.
