This video shows the evacuation certification for the new A380.
Basically any new aircraft type need to meet the safety standard set by the authority before it is given go ahead.
This test was done about 2 years ago and they are all Airbus employee. If I remember correctly it went smoothly with only a couple of people suffer from broken bone.
It is quite amazing actually.
