----------------------------------------
Is this a duplicate of https://issues.apache.org/jira/browse/KAFKA-5041 ?
> Add public version of EmbeddedKafkaCluster
> ------------------------------------------
>
> Key: KAFKA-7852
> URL: https://issues.apache.org/jira/browse/KAFKA-7852
> Project: Kafka
> Issue Type: Improvement
> Reporter: John Roesler
> Priority: Major
>
> Currently, Kafka Client and Streams applications do not have good support for
> writing integration tests.
> Streams added the TopologyTestDriver, which is a much more efficient approach
> for testing Streams applications, specifically, but it's still more in the
> domain of unit testing.
>
> For integration tests, the current state is that people import test artifacts
> from Kafka, which is not a well controlled public API.
>
> It might be possible to offer a shim implementation of Kafka for testing, but
> the API is so large and complicated that this seems like a huge effort that's
> not likely to achieve or maintain perfect fidelity.
> Therefore, it seems like the best thing would just be to clean up the
> EmbeddedKafkaCluster and offer it in a public test-utils module.
