What planet are you from?
Programmers seem able to test everything except that one condition that will

Another way to look at it is that there are usually many, many more
users than application testers. A clever, curious, or just plain inept
user can always find many more weird combinations of input to an
application than can be tested, sometimes nonsensical ones that would
just never occur to a tester to try; and at least a few of these may
give highly undesirable results. Consider z/OS itself as a case in
point. One would hope this is an example of extensively tested
software, yet every release always has a number of fix PTFs, some of
which address problems that were highly fatal to one or more installations.
