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

This example for how to test your application with GoogleTest. While the example showcases types from the BigQuery library, the underlying principles apply for any pair of *Client and *Connection.
Functions
virtual options()
This function is implemented using gMock's MOCK_METHOD().
Consult the gMock documentation to use this mock in your tests.
