Fuzz testing is the process of supplying a program with random inputs and
watching to see what breaks; it has been responsible for the identification
of vast numbers of bugs in recent years — and the fixing of many of them.
Developers generally appreciate bug reports, but they can sometimes be a
bit less enthusiastic about a flood of reports from automated fuzzing
systems. A recent discussion around filesystem fuzzing highlighted two
points of view on whether the current fuzz-testing activity is a good
thing.
