Tyler Hobbs commented on CASSANDRA-12016:
-----------------------------------------
This seems like a good start to making this part of the codebase more testable,
thanks.
To warrant committing this type of mini-testing-framework, we should have at
least a few good use cases for tests implemented. The hints test you linked is
a nice example. Did you have anything else in mind that might be a good fit
for this?

> 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.
