Hi Laurent, You can take a look at Flink's MiniClusterResource JUnit test rule, and its usages in the codebase for that. The rule launches a Flink MiniCluster within the same JVM, and submission to the mini cluster resembles how it would be submitting to an actual Flink cluster, so you would already be able to catch problems such as operator serialization errors.
