I don't recommend starting Pulsar contributions in making such refactoring in tests. This would cause a lot of churn in the code base without much added value. We should first have a broader discussion around test improvements on the dev mailing list and then proceed into action.
@heesung-sn has started such a discussion with PIP-390 #23565, thread is https://lists.apache.org/thread/fn3rk1x7v9291qh3g6vf4jxhvq6zc4mm . You are welcome to participate in the discussion and making the decisions.
