-----------------------------------
Summary: Add "echo" request
Key: KAFKA-1822
URL: https://issues.apache.org/jira/browse/KAFKA-1822
Project: Kafka
Issue Type: Improvement
Components: core
Reporter: Gwen Shapira
Assignee: Gwen Shapira
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.
