−"""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.
