[jira] [Commented] (KAFKA-6339) Integration test with embedded
kafka not working
[ https://issues.apache.org/jira/browse/KAFKA-6339?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16284946#comment-16284946 ]
DHRUV BANSAL commented on KAFKA-6339:
-------------------------------------
I am writing a different application, where I am trying to write integrated test with embedded kafka. (code provided above). Now this integration test is working perfectly fine with release 0.10.0.0, but when I upgraded the version to 0.11.0.2 I am getting following error:

> I am using Kafka version - 0.11.0.2

> assertEquals("test-message", new String(consumedRecord.value(), StandardCharsets.UTF_8));
> kafkaServer.shutdown();
> zkClient.close();
> embeddedZookeeper.shutdown();
> Please provide support for the same and there should be proper documentation for the intergration test with each release.
