Might be only local, not 100% sure, yet.
I can definitively see enums (room & function) that are still present from previous tests and cause errors (because certain object still is member of an enum, that should not be there at all).
I once saw a state object still present for all tests and even after testing was done I could find it in objects.jsonl file.
From what I understood databases should be empty (or at least at some defined status) at the beginning of each test.
