Is it possible to mock up backend calls from persistent state objects

[JörgModerator]

A question regarding regression testing. We would like to perform/setup regression tests for our pilot project. For that we need to mockup backend calls.

All integration logic is in the persistent state objects. So the question is:

Is it possible to mock up backend calls from persistent state objects?

If yes how to do it?

This is not directly supported with the E2E Analyzer, but there are two approaches to achieve this nevertheless:

1.  Set the <<E2ETestable>> stereotype on the PState class, then you will get all the implementation as synchronous operations in the E2E Analyzer and you can apply regression test on these. This is the recommended approach.
2. You implement the mock-ups directly in the model and you have a parameter (for instance a setting) where you can choose whether you run in regular mode or in test mode with mock-ups.
