YES! Just learned about this concept while reading an article
   about "20 scariest cloud disasters - and lessons learned".
   Apparently, Netflix engages in Chaos Engineering, which is one
   of the reasons for their amazing stability. I never heard of it
   but I guessed, and correctly. In short: Start with a stable
   state system. [not all engineering utilizing state system
   thinking, especially networks, even though they SHOULD]
   Then subject it to every possibility you can imagine. See if it
   holds. See where it fails. Throw everything at it. Revise the
   state system slightly. Do it again. And again... and again. This
   short article goes into the 'gist' of it a little better than I
   did. At one time, I thought this is how all things were tested.
   But I've found that optimism replaces testing: Systems are too
   often designed for "best case scenarios" and problems are
   addressed as they arise. [think Microsoft]
