First of all thanks for this contribution!
This style of "fake mocks" based testing is good. The deliverer and bft_deliverer are tested this way. I will accept all the tests written here.
However, the issue calls for a more explicit style of testing - against a real gRPC service (a mockup for testing, not a real orderer).
See for example how it's done here:
orderer/common/cluster/deliver_test.gowhere there is adeliverServerthat implements the "Deliver" API. You can copy the deliverServer from there, and run the DeliveryRequester against it.
