Herman Kolstad Jakobsen updated KAFKA-19594:
--------------------------------------------
Description:
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”.
