-------------------------------------
Summary: Reduce RackAwarenessIntegrationTest to a unit test
Key: KAFKA-14130
URL: https://issues.apache.org/jira/browse/KAFKA-14130
Project: Kafka
Issue Type: Improvement
Components: streams, unit tests
Reporter: Guozhang Wang
While working on KAFKA-13877, I feel it's an overkill to introduce the whole
test class as an integration test, since all we need is to just test the
assignor itself which could be a unit test. Running this suite with 9+
instances takes long time and is still vulnerable to all kinds of timing based
flakiness. A better choice is to reduce it as a unit test, similar to
{{HighAvailabilityStreamsPartitionAssignorTest}} that just test the behavior of
the assignor itself, rather than creating many instances hence depend on
various timing bombs to not explode.
The scope of this ticket is to refactor the {{RackAwarenessIntegrationTest}}
into a {{RackAwarenessStreamsPartitionAssignorTest}}.
