When testing resiliency software testing isn't the whole of the thing.
I spent a lot of time at new job (well 18mths now) on making the software side more resilient, we still had a site wide outage of internet access and comms and internal systems because one of the women in the sales office unplugged a socket in the ingress comms cabinet to plug her hair straighteners in.
Coincidentally my request to have physical access control on all the comms cabinets shot right up the list.
The boundary layer between software and hardware itself has to be tested, the real world is a messy place :).
