  # suite to get integration with FlexMock.  When this module is
  # included, the mock container methods (e.g. flexmock(), flexstub())
  # will be available.
  #
  # <b>Note:</b> If you define a +teardown+ method in the test case,
  # <em>dont' forget to invoke the +super+ method!</em> Failure to
  # invoke super will cause all mocks to not be verified.
