Currently, Blob (InputStream) and Timer (TimerRequest) types cannot be unit tested.
Doing something like
req = func.TimerRequest()results in an error sayingTypeError: Can't instantiate abstract class TimerRequest with abstract methods past_due. This is because both Blob and Timer are missing the abstract layer that the other types have. This change adds the layer, allowing for unit testing, but not changing any other details.This change is already covered through our unit tests & does not impact current functionality.
Fixes Azure/azure-functions-python-worker#737
