Testing != reality
I've seen software fail. And inevitably, someone asks the question "why don't they test these things?"
But of course they are tested. Many companies spend incredible amounts of time and effort to test their wares before they ship.
The interesting truth is that testing is not real life. The old war truth says "no plan survives contact with the enemy", and role-players might say "no scenario survives contact with the players". Real life is just so full of variety, inventive people, even physical limits like dirt and grit that no amount of testing can truly represent real life.
Martial artists know that practice will help. But a real situation is always different. Practice too little and you're overconfident. Practice the wrong things and you're too rigid to adapt. Same with software testing.
When software ships, it goes to a battlefield. Many times it survives. But many times it does not.
