I feel like we practiced a question similar to this, and using the Pub/Sub emulator was highlighted as a reliable method. So, D sounds right to me.

Adding a filter by tester to the subscription could be a good way to isolate the tests, but I'm not sure if that would guarantee the order of message processing.

The Pub/Sub emulator, huh? Sounds like a fancy version of the 'ol trusty crystal ball. I wonder if it comes with a magic 8-ball as a bonus.

The Pub/Sub emulator? Isn't that like using a crystal ball to predict the future of your messages? I'm going with option A, the mocking framework. It's the only way to be sure.
