Again, unless I've missed a statement, we don't know if Boeing has tested for this case internally. This case being "pilots untrained and unfamiliar with the MCAS system recovering from a catastrophic systems failure / error". They are at fault no matter what though from straying from their long held principle that the pilot has the final say on control of the aircraft. Inputs from the yoke and throttle levers should always supercede the computer.
