Fuzz testing, a technique for detecting critical software vulnerabilities, combines various methodologies from previous research to improve its effectiveness. For fuzzing practitioners, it is imperative to comprehend the effects of distinct techniques and select the ideal configuration customized to the program they need to test.

The release of AFL marked an important milestone in the area of software security testing, revitalizing fuzzing as a major research topic and spurring a large number of research studies that attempted to improve and evaluate the different aspects of the fuzzing pipeline.
