Mutation testing system

An old coder's strategy for the agent era: don't read the code — make it run the gauntlet. Evidence-first development skill for coding agents, inspired by Uncle Bob.

Mutation testing for Python

MutPy is a mutation testing tool for Python 3.x source code

Open Source, Language Agnostic Mutation Testing

Mutation Testing for Ethereum Smart Contracts

Regexp based tool for mutating generic source code across numerous languages

Python mutation testing: test your tests! Safely run mutation trials without source code modifications and see what will get past your test suite.

MutAP: A prompt_based learning technique to automatically generate test cases with Large Language Model

We propose a novel DL-based mutation technique (LEAM), which adapts the syntax-guided encoder-decoder architecture to build two sub-models based on AST information, for better learning to represent real faults and ensuring syntactic correctness of mutation faults.

This is a simple script to perform mutation testing on c/c++ like programs

Evaluation of two binary mutation engines based on ddisasm and rev.ng

Brakes for the software factory: deterministic checks, a fresh-context reviewer that commits its fixes, and one-way-door triage for coding agents. Built on Matt Pocock's skills. Every rule proven to bite.

Django integration for the mutation testing framework MutPy.

Deterministic pre-push verification for AI-assisted codebases: AST mutation testing, credential scanning, sandbox-escape detection, mock-usage alerts, and dependency hallucination defense.

Exit-code checks for AI coding agents: catches test tampering in diffs, tests that cannot fail, fixes that only satisfy the tested inputs, and weakened assertions. Benchmarked on 630 real PRs and QuixBugs.

Mutation testing for your LLM evals — degrade the system under test and check whether your evals would actually catch a regression.
