Needs monitoring to test for...
Half a brain or less.
Most software testing is just stress testing, running a lot of stuff at the same time, and is not hack testing or giving over to software engineers employed in finding and removing the hacks, holes and misgivings.
Many in the past said if aircraft or refrigerators crashed as much as the Microsoft operating system there would be much noise made and it would be banned.
Well now there is Automobiles, Aircraft, Refrigerators Microwave, Brain monitors, Pacemakers, Insulin dose devices, Mobile phones, Centrifuges, Power stations, Water plants, etc that do and while there are rules for electronic emissions and electronic devices not much software has been banned yet, or much noise made about the problems with it being a major risk to human safety.
