Well the fundamentalists will say that there is no requirement to check anything beyond what the bible says because the great God Boeing will ensure that nothing can go wrong go wrong if your prayers are offered up directly from the bible.
The atheists and agnostics among us will say believe in nothing, trust not entirely in God or His bible but cover your arse by checking everything to be sure to be sure.
You are looking for a failed test to indicate the possibility - however remote - that the lack of a warning is no longer confirmation that the fire is truly out.
What you do with that information is beyond the scope of the QRH because that document can not cover every eventuality and does not claim to cover every eventuality. That is why you get paid the big bucks. Anyone can read a QRH and unthinkingly follow procedures.
Capts Haynes and Sullenberger are prime examples of pilots who went beyond the QRH to save lives. There are others like the skippers of the Gimli glider and the topless 737.
