"""Unit test base class for tests of `compatibility.MetricTask`.
This class provides tests of the generic ``MetricTask`` API. Subclasses must override `taskFactory`, and may add extra tests for class-specific functionality. If subclasses override `setUp`, they must call `MetricTaskTestCase.setUp`. """
# For some reason, setUp for the test cases defined in MetricTaskTestCase # calls the wrong factory if you make it a classmethod """A nullary callable that constructs the `compatibility.MetricTask` to be tested.
If a concrete task's constructor satisfies the requirements, its type object may be used as the factory. """
