Fuzz testing or fuzzing is a software testing technique that provides invalid, unexpected, or random data to the inputs of a program. If the program fails, the defects can be noted.
Fuzz testing is often used in large software development projects that employ black-box testing.
The oldest and simplest form of fuzzing, sending a stream of random bits to software, originated from Prof. Barton Miller's group at the University of Wisconsin in 1988.
Another common technique that is easy to implement is mutating existing input by flipping bits at random or moving blocks of the file around. But the most successful fuzzers have detailed understanding of the format or protocol being tested.
Fuzz testing reveal many different behaviors. Straight-up failures such as crashes, assertion failures, and memory leaks are easy to detect. The use of a memory debugger can help find bugs too subtle to always crash.
Fuzz testing is especially useful against large C or C++ applications, where any bug affecting memory safety is likely to be a severe vulnerability.
Developers need to reproduce errors in order to fix them. For this reason, almost all fuzz testing makes a record of the data it manufactures, usually before applying it to the software, so that if the computer fails dramatically, the test data is preserved.
