I assume you are referring to the `TopologyTestDriver`?
How do you pass/specify the serdes?
For `TestInputTopic` and `TestOutputTopic` you would pass (de)serializer
instances and thus you will need to call `configure()` in your test code
explicitly.
Similarly, if you pass `Serde` instances via `Consumed`, `Produced`,
`Materialized` et al. configuration objects, you would need to call
`configure()` explicitly in your own code (for both test and production).
Both KafkaStreams and TopologyTestDriver would only call `configure()`
for default serdes that you specify via the provided properties.

Hello, we have been using the streams testing suite for some time now.
We use custom serializers/deserializers for our kafka data, and allow
for some custom configuration of the serdes via the
‘configure(Map<String,Object>)’ method. Something we noticed is that for
the TopologyTestDriver this is never called, causing some issues for our
stream tests. I also confirmed that for the actual streams code this
method is always called when starting the stream instances.
So my question is that is this case (and possibly others I’m not aware
of) valid for updating the testing suite drivers to more closely follow
the life cycle of the production streams code, life cycle and logic?
Thanks in advance,
