Application developers may want to test their code with simulated responses, including errors, from an object of type TopicStatsServiceClient. To do so, construct an object of type TopicStatsServiceClient with an instance of this class. Then use the Google Test framework functions to program the behavior of this mock.

This function is implemented using gMock's MOCK_METHOD().
Consult the gMock documentation to use this mock in your tests.
