In the short period of time it takes for us to get organised/draining mavlink connections, the ArduPilot process might block writing to the primary mavlink connection - in which case we'll never get the message we requested.
Should solve

This has been unused for a long time, and is getting in the way of reforms. Its position as a test rather than as a part of a framework was always going to cause oddities, particularly after we split the Copter tests into several chunks.
We had a pattern emerging of using the test name as the method name to contain the actual test. We also tended to duplicate the docstrings in the test description - or omit the docstring.
This uses reflection to retrieve both the test name and the description, meaning less duplication of this information and enforcing having docstrings on the test methods.
Will clarify the output as currently we look through the text messages for all of the previous gps types when trying to find the detection message for the current GPS
