toxy - Hackable HTTP proxy for resiliency testing and simulated network conditions

Javascript

Hackable HTTP proxy to simulate server failure scenarios, resiliency and unexpected network conditions, built for node.js.It was mainly designed for failure resistance testing, when toxy becomes particularly useful in order to cover fault tolerance and resiliency capabilities of a system, especially in disruption-tolerant networks and service-oriented architectures, where toxy may act as MitM proxy among services in order to inject failure.

go-fuzz - Randomized testing for Go

Go-fuzz is a coverage-guided fuzzing solution for testing of Go packages. Fuzzing is mainly applicable to packages that parse complex inputs (both text and binary), and is especially useful for hardening of systems that parse inputs from potentially malicious users (e.g. anything accepted over a network).Data is a random input generated by go-fuzz, note that in most cases it is invalid. The function must return 1 if the fuzzer should increase priority of the given input during subsequent fuzzing (for example, the input is lexically correct and was parsed successfully); -1 if the input must not be added to corpus even if gives new coverage; and 0 otherwise; other values are reserved for future use.

tavor - A generic fuzzing and delta-debugging framework

Tavor (Sindarin for woodpecker) is a framework for easily implementing and using fuzzing and delta-debugging. Its EBNF-like notation allows you to define file formats, protocols, and other structured data without the need to write source code. Tavor relaxes on the definitions of fuzzing and delta-debugging to enable the usage of its algorithms universally for keyword-driven testing, model-based testing, simulating user-behavior and genetic programming. Tavor is also well-suited for researching new methods without reimplementing basic algorithms.We want to test a service which processes an XML structure. The structure can contain groups and items. A group contains other groups or items. An Item consists of an attribute name with an alphanumeric value. The item's value contains a number. This structure sounds simple but allows an enormous variety of possible outcomes. It is therefore hard to test since a tester has to think about every important possibility if the generation of the test data is done manually. Doing this manually is cumbersome and error-prone. Tavor can be used to automate the generation.

checkers - Property-based testing for JavaScript via ClojureScript's test.check

Javascript

Property-based testing for JavaScript via ClojureScript's test.check. test.check is a Clojure property-based testing tool inspired by QuickCheck. The core idea of test.check is that instead of enumerating expected input and output for unit tests, you write properties about your function that should hold true for all inputs. This lets you write concise, powerful tests.

js-fuzz - An AFL-inspired genetic fuzz tester for JavaScript

TypeScript

js-fuzz is an American Fuzzy Lop-inspired fuzz tester for JavaScript code. It provides coverage-driven analysis and minimization while being fast and extraordinarily simple to use. In the above example, we asked to increase the priority of strings that can be parsed as plain JSON, since we want more of that sort of thing in order to test against JSON5. You can also return Promises from the fuzz function, or take a callback.

cautious-pancake - github generated the repo name for me

cautious-pancake aims to make fuzzing golang packages easier by identifying pure functions. These functions can be easily fuzzed since they only operate on their direct inputs and do not modify global state. The -filter=impure flag will return all functions deemed impure, including the reason for the determination and the -all flag will display information on private functions as well.

FuzzImageMagick - Sample files for fuzzing ImageMagick

Python

Full setup for fuzzing ImageMagick. Currently (2016-02-07) covers over 30% of the codebase. ImageMagick creates temporary files while running. If ImageMagick crashes, the temporary files are not cleaned up. To prevent the fuzzing machine's hard disk from filling up, you can create a cron job to run rm /tmp/magick-* every hour. For more discussion about this issue, see this bug report.
