Stefan Podkowinski commented on CASSANDRA-12016:
------------------------------------------------
Please find the suggested implementation in the linked WIP branch. An example
how a unit test using those classes looks like can be found
[here|https://github.com/spodkowinski/cassandra/blob/3cd4ef203cd147713a6f8c4b1466703436124e0b/test/unit/org/apache/cassandra/hints/HintsServiceTest.java].
I'm looking forward for any feedback.
> Create MessagingService mocking classes

> 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.
