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

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