Fuzz testing

Fuzz testing , or simply fuzzing, is a testing technique that has been around for a long time but it is still one of the lesser-known techniques. The goal is to feed a software system all kinds of invalid input and observe its behavior. For an HTTP endpoint, for example, bad requests should result in 4xx errors, but fuzz testing often provokes 5xx errors or worse. Well-documented and supported by tools, fuzz testing is more relevant than ever with more AI-generated code and complacency with AI generated code. That means it’s now a good time to adopt fuzz testing to ensure code remains robust and secure.
