This class sets up a bunch of test cases which will test both
deferredGenerator and inlineCallbacks based generators. The subclasses
DeferredGeneratorTests and InlineCallbacksTests each provide the actual
generator implementations tested.
c C s | � � �| jd�S )z�
Test that a normal deferredGenerator works. Tests yielding a
deferred which callbacks, as well as a deferred errbacks. Also
ensures returning a final value works.

Ensure that a buggy generator properly signals a Failure
condition on result deferred.

Create a Deferred Generator which yields a Deferred which fails and
handles the exception which results. Assert that the Deferred
Generator does not errback its Deferred.

Just like testHandledTerminalFailure, only with a Deferred which fires
