What is Fuzz Testing?

Fuzz Testing is a dynamic testing method used for finding functional bugs and security issues in software. During a fuzz test a program gets executed with invalid, unexpected, or random inputs, with the aim to crash the application. This is a particularly effective approach to detecting bugs and security vulnerabilities in software.

Running Security Tests On the Source Code

Modern, effortless fuzzing solutions can analyze the structure of the code they are supposed to test. They can generate thousands of automated test cases per second, and mark each path the inputs take through the program. This way a fuzzer gets details feedback about the code coverage, the inputs are reaching during the execution of the source code.

Each Finding Leads to More Findings

Once a fuzzing solution found an input that has caused a crash, they use mutation algorithms to generate even more inputs which can reproduce the finding with a high probability.

Fuzzing Protects Against the Unexpected

Modern fuzzers executes a program with invalid, unexpected, or random inputs. This way you can also cover unlikely or unexpected edge cases, that you would not cover with other testing approaches.
