        """An example mock_{method} ABC method

        This is an ABC providing an example.  As a developer, to see how this
        framework works, simply...
            1. Comment out the raise (but please do not commit the raise)
            2. Comment out the raise in self.fully_mocked_target method
            3. Do a pytest.set_trace at the beginning of this method
                a. The beginning of check_mocks()
                b. The beginning of fully_mocked_target()
            4. Do the following python code in this directory:
                import conftest
                foo = conftest.MockBuilder()
                target = foo.fully_mocked_target()
                foo.mock_method(target, 1, tuple([]))
                target.method()
                foo.check_mocks()

        A standard test within a TesterClass should simply use one of the
        following:
            - fully_mocked_target
            - partially_mocked_target
            - standalone_builder
            - neutron_only_builder
            - bigip_only_builder
            - fully_int_builder
        Please see the ABCM for these.

        NOTE: this ABCM type cannot be a fixture becuase the builder is
        factoried after pytest performs its fixture isolation at compile time.

        NOTE: due to this the attributes starting with '_mock_' are considered
        as part of the algorithm; thus, please do not overload this attr type.

        Additional Kwargs and their meanings (as children should follow):
            - call_cnt: the number of times the mocked method is called in
              production
            - expected_args: the expected args for at least one call within
              the production code during the test.  Note that this means that
              only one of the mocked-method's calls... see check_mocks() for
              how this is validated
            - static: A static value that will be used in favor over setting
              the mocked method to a mock.Mock
        """
