test-quality

Portable AI code quality reviews for Codex, Cursor, Copilot and other coding agents: six Agent Skills for architecture, technical debt, tests and remediation.

Playwright and Cypress E2E testing skills for AI agents. Generate Playwright tests, review test quality, and debug failures in Claude Code and Codex.

Mutation Testing for Ruby

Mutation-tests every test your coding agent writes and blocks 'done' until the score passes (default 80%, up to two rounds). Claude Code, Codex, OpenCode, Pi. Java, Kotlin, Python, TS/JS, Go, C#.

🧪 Intelligent test analysis tool that finds duplicate and redundant tests using coverage analysis. Improve test suite quality with detailed reports and pytest integration.

Find weak tests before they become a false-green CI. Deterministic test-effectiveness analysis for JavaScript & TypeScript: no-assertion & trivial-assertion detection, 0-100 suite score, PR reviews via GitHub Action. Zero config: npx trashtests scan. Works with Jest, Vitest, Mocha & Ava.

Mutation testing for GDScript and Godot: find the bugs your green tests would miss.

Static analysis tool that scores TypeScript tests across 6 quality dimensions. Works with Jest, Vitest, Playwright, Cypress, and Mocha.

AI-powered GitHub Action that analyzes test quality, provides scores, identifies issues, and suggests improvements through OpenAI's GPT models. Posts detailed reports directly to your pull requests.

Static Playwright test-quality grading with actionable findings and example reports.

Verification system that catches coding agents falsely claiming task completion. Runs 4 parallel checks (file integrity, test quality, scope narrowing, optional LLM judge) over task+claim+diff and returns a weighted 0-100 confidence score with evidence.

Fast, extensible mutation testing engine powered by Rust. Built for Dart, Flutter, and beyond.

Find false-green tests: tests that pass without verifying anything. Deterministic Python/pytest AST scanner (C1-C59 + PL config-audit), zero-dep, CI-ready.

Automated chaos testing for Python — fault injection, property assertions, and stateful exploration

Run a canfail declaration in one GitHub Actions step, and fail for a stated reason.

Agent skill + manifesto to audit and clean up test suites: detect test smells and refactor safely

Runtime risky-test detection for RSpec: reports tests with no expectations or unexpected output.

An auditing engine for code you did not write. certify plants faults and runs YOUR suite against each one; review hands the code to a cold agent that must prove every claim with a script corral runs. Each verdict is a signed, hash-linked entry on a git branch any DuckDB queries straight off GitHub.

Local-first MCP server that runs isolated mutation testing against a codebase to expose the gaps its test suite does not cover. Wraps StrykerJS, cosmic-ray, cargo-mutants and Infection behind one tool surface.

Mutation testing for Go, defined by a language-neutral standard. The command dokimi-mutate-go and the function mutate.Check report each change to your code that your tests miss.
