Boyang Chen commented on KAFKA-6381:
------------------------------------
[~mjsax] I did have a try on this one, and found that I could not come up with
a valid mock KStreams. So leaving this one unassigned right now since I might
not have time to tackle it. Sorry for taking so long to response!
> 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:
> {quote}
> 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.
> {quote}
> We should extend the current test method and/or add new test methods to cover
> this and other scenario.
