> Key: KAFKA-4461

> Project: Kafka
> Issue Type: Bug
> Components: streams

> *Problem*
> When using ProcessorTopologyTestDriver in the latest Kafka 0.10.1, the
> combination of map and .groupByKey does not produce any result. However, it
> works fine when using KStreamTestDriver.
> The topology looks like this:
> {code}
> builder.stream(Serdes.String, Serdes.Integer, inputTopic)
> .map((k, v) => new KeyValue(fn(k), v))
> .groupByKey(Serdes.String, Serdes.Integer)
> .count(stateStore)
> {code}
> *Full examples*
> Examples for ProcessorTopologyTestDriver and KStreamTestDriver:
