You might take a look at the KafkaServerTestHarness [1] if you’re not already familiar with it. It’s not exactly “mock”, but it makes it easy to test Kafka functionality without needing to connect to any external broker or ZK processes. We ported this test harness to Java for our junit and integration tests, and use a junit suite to keep it running for all tests.
