Unittesting with dataservices

I want to use the dataservices within unit tests. All my tries were failing.
Best case: I could give it a directory for the models and than alls runs in an inmemory DB.

What is the issue?

I would like to have a minimal code sample for a Unit test which is using a injected dataservice component.

You can get inspired in the DS code: <INTERNAL_LINK>

You send the link to the whole repository. Was this intended?

Yes. You can look at our tests and check which one suits to you best.
