>                 URL: https://issues.apache.org/jira/browse/KAFKA-10066
>             Project: Kafka
>          Issue Type: Bug
>          Components: streams-test-utils
>    Affects Versions: 2.5.0
>            Reporter: Stefaan Dutry
>            Assignee: Matthias J. Sax
>            Priority: Minor
>
> When testing a Kafka stream we need the TopologyTestDriver.createOutputTopic 
> to take record headers into account.
> Is it possible to use the record headers when deserialising when using the 
> TopologyTestDriver.createOutputTopic?
> The only thing that needs to change is: 
> {code:java}
> final K key = keyDeserializer.deserialize(record.topic(), record.key());
> final V value = valueDeserializer.deserialize(record.topic(), 
> record.value());{code}
> into: 
> {code:java}
> final K key = keyDeserializer.deserialize(record.topic(), record.headers(), 
> record.key());
> final V value = valueDeserializer.deserialize(record.topic(), 
> record.headers(), record.value());{code}
>
