If they wanted a realistic test under conditions where the airplane will be used a lot is a hadj simulation. Get 800 pilgrims with their pigs and chickens, shopping bags full of stuff, sterno stoves, as well as at least 100 80-year-old near-death Grandpa Muhammeds . . . then run the test. Somehow I don't think that would go as well as a bunch of fit gym goers and disciplined and pre-briefed Airbus employees.
