Gwen Shapira commented on KAFKA-1822:

Thanks! I think  ClusterMetadataRequest can work here.
I'll close this JIRA and re-use ClusterMetadataRequest.

>                 URL: https://issues.apache.org/jira/browse/KAFKA-1822
>             Project: Kafka
>          Issue Type: Improvement
>          Components: core
>            Reporter: Gwen Shapira

>             Fix For: 0.8.3
> Currently there is no simple way to generate a request and validate we receive a response
without adding a lot of dependencies for the test.
> Kafka request classes have quite a few dependencies, so they are not really usable when
testing infrastructure components or clients.
> Generating a byte-array with meaningless request key id as it is done in SocketServerTest
results in unknown request exception that must be handled. 
> I suggest adding an EchoRequest, EchoResponse and EchoHandler. The Request will be the
usual header and a bytearray. The Response will be a response header and the same bytearray
echoed back.
> Should be useful for client developers and when testing infrastructure changes.
