You are right, Disney is perfect and always test everything completely.
Personally, I don't buy the pressure washer story. In my opinion what happened with the EPCOT world celebration gardens lights was poor sourcing and poor installation and a rush to complete whatever they were trying to do in building that center piece.
And you are right again, no level of testing was going to correct poor sourcing and poor installation and a rush to complete whatever they were trying to do there.
So, yes, while I do make jokes about testing, the failure of EPCOT world celebration Gardens lights had nothing to do with lack of testing.
