             Summary: Improve KafkaStreamsTest for localThreadMetadata
                 Key: KAFKA-6381
                 URL: https://issues.apache.org/jira/browse/KAFKA-6381
             Project: Kafka
          Issue Type: Improvement
          Components: streams, unit tests
            Reporter: Matthias J. Sax
            Priority: Minor


Currently, we have a rather basic test for {{KafkaStreams#localThreadMetadata}} (ie, {{KafkaStreamsTests#shouldReturnThreadMetadata()}}.

In a PR discussion [~guozhang] mentioned:

I'm wondering if it is better to fill into the topology with some processor and then check the following active and standby tasks as non-empty would cover more scenarios? In addition, we can use waitForCondition to wait for the state to become RUNNING and the tasks list become non-empty.

We should extend the current test method and/or add new test methods to cover this and other scenario.
