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.
