This was one part I was a little torn on, and I'd be open to alternative ways to track data sent from the mock socket to the mock server

It feels like the "boy scout" way of doing this would be with subscription callbacks, but since we'd likely just be checking the contents for a single isolated test case, that'd add more boilerplate to all test cases when we really just care about what data got sent
