Substantial experience with flow action unit tests, which is nothing
special since you simply test for expected string return values for
various inputs. Testing entire flows (e.g. transitions, view state
rendering, flow end states) is limited but I understand the mechanics
enough to do it.

It seems feasible at face value to begin by modeling CAS protocol
behavior as a standalone flow and validate with unit tests. Hopefully
IdPv3 development proceeds in parallel enough to transition to in situ
testing down the road.
