Wait until you find out about the cat test. It found a failure mode no human had thought of. No amount of the developer claiming a test like that was not fair was enough to invalidate the results. No actual cats were harmed but treats may have been given.
Do you have more context? I'm having trouble googling what you're referencing.
Simulate a cat walking on the keyboard to handle weird inputs?
Isn't that just fuzzing? I thought maybe there was a specific thing called the cat test.
