---------------------------------------
Hi Dhruv, Can you please let us know more about the problem you are facing?
> Integration test with embedded kafka.
> -------------------------------------

> Key: KAFKA-6339
> URL: https://issues.apache.org/jira/browse/KAFKA-6339
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 0.11.0.2
> Reporter: DHRUV BANSAL
>
> I am using Kafka version - 0.11.0.2
> Trying to write an integration test for one of the components I am writing
