-------------------------------------------

             Summary: Add simple end-to-end test for Stateful Functions
                 Key: FLINK-16159
                 URL: https://issues.apache.org/jira/browse/FLINK-16159
             Project: Flink
          Issue Type: Improvement
          Components: Stateful Functions, Test Infrastructure
    Affects Versions: statefun-1.1
            Reporter: Tzu-Li (Gordon) Tai
            Assignee: Tzu-Li (Gordon) Tai


Often in our review process of changes to the Stateful Functions project, we often end up wanting to do a simple sanity check by running the simple greeter example with docker-compose.

Ideally, this should really be an end-to-end verification program that:
* Starts a Kafka broker and a simple stateful function application that has a Kafka ingress and egress
* Uses the Kafka Java client to write some inputs to the broker, reads and verifies output

With testcontainers (https://www.testcontainers.org/) this might even be achievable as a Junit test, which runs only after the Maven packaging phase.
