Herman Kolstad Jakobsen updated KAFKA-19594:
--------------------------------------------
Summary: Multiple-partition topic support for TopologyTestDriver (was:
Multiple-partition-topic support for TopologyTestDriver)
> Multiple-partition topic support for TopologyTestDriver
> -------------------------------------------------------
>
> Key: KAFKA-19594
> URL: https://issues.apache.org/jira/browse/KAFKA-19594
> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Reporter: Herman Kolstad Jakobsen
> Priority: Minor
>
> The TopologyTestDriver is great for writing fast and reliable tests for
> Streams applications. However, a shortcoming of the TopologyTestDriver is
> that it only supports topics with one partition, therefore making it
> difficult to test that data has been correctly partitioned throughout the
> entire topology. This is especially relevant for topologies utilizing PAPI,
> where the user has to manage the partitioning of the data.
> A simple starting point could be to keep the current fully synchronous
> execution for a single input event, just with a TestInputTopic that supports
> a “Partitioner”.
