I'm assuming you haven't read the book or you'd know its all in eiffel
and that the preconditions and postconditions are checked unless turned
off for production code.

In any event, if you do follow the "check for every possible input and
then some" mantra then the only thing that happens differently is that
your programmers introduce bugs into the code that fail nicely rather
than poorly. They then go and acquire an intimate knowledge of the
interfaces (which they should have done in the first place).
