> Attempting to join two KTables yields a `Topology` that, when tested with `TopologyTestDriver` by adding records to the two `TestInputTopic`s, results in an empty `TestOutputTopic`.
> I'm attaching a very small reproduction. The code is in Scala. The project is therefore an "sbt" project. You can reproduce the results from your shell with `sbt test`. The failure output will include the `describe` of the `Topology` in question.
