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 > --------------------------------------- > > Key: CASSANDRA-12016 > URL: https://issues.apache.org/jira/browse/CASSANDRA-12016 > Project: Cassandra > Issue Type: New Feature > Components: Testing > Reporter: Stefan Podkowinski > Assignee: Stefan Podkowinski > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
