Hi Georg,

there are two classes "MultipleProgramsTestBase" and
"StreamingMultipeProgramsTestBase", which your integration tests can
extend from.

This will spin up a local Flink Mini-Cluster before the test execution
and tear it down afterwards.

I have also recently build a small Flink-JUnit rule available on Github
to make this a little bit easier and  more flexible [1]. The snapshot
version should be available in the sonatype open source repositories in
the next days. Let me know, if it seems useful to you.

This is for integration tests of our jobs or parts of the jobs though.
For unit tests we usually mock the RuntimeContext.

Cheers,

Konstantin
