Sure, I agree with that as well, what I should have said was I have an
issue with the notion that testing (of any sort) is all that is needed
to reach high assurance. Directed and random tests BOTH failed to
catch the FDIV bug. You need methods that demonstrate the absence of
defects, not just fail to demonstrate their presence.
