Saïd, sorry for late reply. Avro records are basically supported. However, there are no plans atm to integrate the test driver with a schema registry. Note, that Apache Kafka does not provide a schema registry by itself. If we integrate one RS, we need to integrate all of them -- that is something Apache Kafka should not do from my point of view.
Thus, if you want to use ArvoSerdes that use a schema registry, those should mock be mocked accordingly. However, there is nothing this KIP can help with this regard IMHO. I left a comment on the ticket to pointed out. :) -Matthias On 1/17/18 1:29 AM, Saïd Bouras wrote: > Matthias, > > What about testing topology that use avro schema ?
