Hi Tzu-Li, thanks a lot for your answer. I will try this!
However, I was looking for something that does fully simulate a Flink cluster, including job-manager to task manager serialization issues and full isolation of the task managers (I guess in the MiniClusterResource, we are still on the same JVM, so static classes will still be available to all operators, which is different than on a real cluster). Cheers, Laurent.
