> Interactions between clients and nodes in the cluster are taking place by exchanging messages through the {{MessagingService}}. Black box testing for message based systems is usually pretty easy, as we're just dealing with messages in/out. My suggestion would be to add tests that make use of this fact by mocking message exchanges via MessagingService. Given the right use case, this would turn out to be a much simpler and more efficient alternative for dtests.
