Fuzzinator: An Open-Source Modular Random Testing Framework

There is no fuzzing without a random test generator, but to be useful in practice, it needs to be accompanied by some similarly important components: solutions to feed test cases to the target system, unique error detectors, automatic test case reducers, or issue reporters. Unfortunately, many projects either still focus only on test case generation and give no support for the rest of the tasks, or they tightly couple several components into a monolithic artifact. In this paper, we introduce the Fuzzinator open-source random testing framework that supports connecting all, potentially independently developed components of a fuzzing setup in a modular way.
