Description
As of now, there seems to be not much guidance on how to approach testing. Although it's true sjwiesman that
Unlike other flink apis, the sdk doesn’t pull in the runtime so testing should really look like any other code. There isn’t much statefun specific.
I think that at the very least testing should be mentioned as part of the docs, even if it is only to stress the above fact. Indeed, as reported by trohrmann, there seems that there are already some test utilities in place but they are not well-documented, plus some potential ideas on how to improve on that front
Testing tools is definitely one area where we want to improve significantly. Also the documentation for how to do things needs to be updated. There are some testing utils that you can already use today: https://github.com/apache/flink-statefun/blob/master/statefun-sdk-java/src/main/java/org/apache/flink/statefun/sdk/java/testing/TestContext.java…. However, it is not well documented.
Once the overall guidelines are in place for different testing strategies, tests could be added to the examples in the playground.
