------------------------------------
Hi [~bchen225242],
I would take up this. Im a newbie and would be a good way for me to start off
via Tests.
Assigning it to myself. Let me know if there are concerns.
Thanks

> Key: KAFKA-9679
> URL: https://issues.apache.org/jira/browse/KAFKA-9679
> Project: Kafka
> Issue Type: Test
> Components: consumer, streams
> Reporter: Boyang Chen
> Priority: Major
> Labels: help-wanted, newbie, newbie++
>
> Right now in MockConsumer we shall return illegal state exception when the
> buffered records are not able to find corresponding assigned partitions. This
> is not the case for KafkaConsumer where we shall just not return those data
> during `poll()` call. This inconsistent behavior should be fixed.
> Note that if we are going to take this fix, the full unit tests need to be
> executed to make sure no regression is introduced, as some tests are
> potentially depending on the current MockConsumer behavior.
