Dear Kafka community, I want to propose KIP-247 to add public test utils to the Streams API. The goal is to simplify testing of Kafka Streams applications.
Please find details in the wiki: https://cwiki.apache.org/confluence/display/KAFKA/KIP-247%3A+Add+public+test+utils+for+Kafka+Streams This is an initial KIP, and we hope to add more utility functions later. Thus, this KIP is not comprehensive but a first step. Of course, we can enrich this initial KIP if we think it falls too short. But we should not aim to be comprehensive to keep the scope manageable. In fact, I think we should add some more helpers to simplify result verification. I will update the KIP with this asap. Just wanted to start the discussion early on. An initial WIP PR can be found here: https://github.com/apache/kafka/pull/4402 I also included the user-list (please hit "reply-all" to include both lists in this KIP discussion). Thanks a lot. -Matthias
