Matthias J. Sax commented on KAFKA-6460:
----------------------------------------
I did not think about how to make it work. But what you suggests SGTM – in
fact, `TopologyTestDriver` uses `InternalTopologyBuilder` already.
Overall (from experience) this seem to be a tricky ticket – thus, I would like
to have a PR in parallel to the KIP – otherwise, it will be hard to get right.
[~shung] How does this sound to you?
> Add mocks for state stores used in Streams unit testing
> -------------------------------------------------------
>
> Key: KAFKA-6460
> URL: https://issues.apache.org/jira/browse/KAFKA-6460
> Project: Kafka
> Issue Type: Improvement
> Components: streams, unit tests
> Reporter: Guozhang Wang
> Assignee: Yishun Guan
> Priority: Major
> Labels: newbie++
>
> We'd like to use mocks for different types of state stores: kv, window,
> session that can be used to record the number of expected put / get calls
> used in the DSL operator unit testing. This involves implementing the two
> interfaces {{StoreSupplier}} and {{StoreBuilder}} that can return a object
> created from, say, EasyMock, and the object can then be set up with the
> expected calls.
> In addition, we should also add a mock record collector which can be returned
> from the mock processor context so that with logging enabled store, users can
> also validate if the changes have been forwarded to the changelog as well.
