So, for clarification then,
was that test succesful?
Seems like an awful lot of smoke / fire / vibration going on in there. Although it's not total catastrophic failure...

I don't know
There was a lot of smoke and fire though; I've seen other tests where that doesn't happen (although the engine is not completely enclosed here. They are just testing the part of the cowling that needs to contain a failure of the front fan; shrapnel coming out of the back of the engine isn't a problem).
The vibration issue is solved by connecting the engine to the wing using pins that are designed to break if the engine vibrates too much (i.e. enough to damage the wing).
They can design for some vibration, but only so much because every blade off event will be unique/not entirely predictable.
