Hi @tenthe,

I pushed my changes to the branch apache:2374-provide-a-framework-to-easily-unit-test-processing-elements. I am having issues with moving the code to a different module. When I tried moving it to streampipes-test-utils I had errors with cyclic dependencies. I created a new module streampipes-test-utils-executors, but getting this error:
The following artifacts could not be resolved: org.apache.streampipes:streampipes-test-utils-executors:jar:tests:0.95.0-SNAPSHOT (absent): org.apache.streampipes:streampipes-test-utils-executors:jar:tests:0.95.0-SNAPSHOT was not found in https://repository.apache.org/snapshots

How should I proceed with that?

Regarding the functionality you can see commit c25b1be

All tests are working. I have identified 4 scenarios for the selector prefix:

1. Default. By default the prefix will be an empty string
2. SAME_PREFIX. Will use s0 for all events
3. ALTERNATE. Will alternate between s0 and s1
4. Custom. Accepts a list of prefixes that will be iterated over during event generation.

I assume after the issue with maven modules is fixed I can create a PR from 2374-provide-a-framework-to-easily-unit-test-processing-elements to the dev branch
