[jira] [Created] (KAFKA-13648) KRaft ClusterInstance does not allow for deferred start

[David Arthur (Jira)]

David Arthur created KAFKA-13648:


 Summary: KRaft ClusterInstance does not allow for deferred start
 Key: KAFKA-13648
 URL: https://issues.apache.org/jira/browse/KAFKA-13648
 Project: Kafka
  Issue Type: Bug
  Components: unit tests
Reporter: David Arthur


In our JUnit testkit extension, we allow for a cluster to be started explicitly 
in the test by annotating a test with AutoStart.NO. This allows for additional 
configuration or setup to be done in the test method before starting the 
cluster. For example:


{code:java}
@ClusterTest(clusterType = Type.ZK, brokers = 3, autoStart = AutoStart.NO)
public void testSomething(ClusterInstance clusterInstance) {
clusterInstance.config().serverProperties().put("foo", "bar")
clusterInstance.start();
// ...
}
{code}

This works fine for ZK clusters, but is broken for KRaft clusters.
