This question came up today: OK, say you mock, how do you construct a working multi-process representation of how C* actually works from within a unit test without running the code that actually constructs the cluster?
1) Don't do that (construct a multinode cluster in a test) just mock the crap out of it. http://www.baeldung.com/mockito-verify 2) dtests Dtest don't actually do this in the classic sense. One challenge is code-coverage. For many projects I use cobertura. http://www.mojohaus.org/cobertura-maven-plugin/. Cobertura can't (as far as know) can not instrument N JVMs and give you coverage. Bringing up a full on cluster to test something is slow, compute intensive, and quite hard. 3) Fix it https://issues.apache.org/jira/browse/CASSANDRA-7837 https://issues.apache.org/jira/browse/CASSANDRA-10283 *Impossible you say! No NoSQL JAVA DATABASE CAN DO THIS!!!* https://www.elastic.co/guide/en/elasticsearch/reference/current/integration-tests.html Wouldn't that be just the bees knees???
