What coverage metrics can I enforce?

You can set thresholds for line, branch, and function coverage, as well as define 100% coverage requirements for critical paths like auth or payments.

Can I use this on a legacy project with low coverage?

Yes, it features a 'Gradual' adoption mode that can focus on validating new code only or logging coverage without blocking commits.

What languages does the TDD Enforce skill support?

It provides specialized implementation patterns for JavaScript/TypeScript (Husky), Python (pre-commit), and Java (Maven/Gradle).

How does it validate test presence?

The skill includes logic to check staged source files and verify that corresponding test files exist, preventing the commitment of untested logic.

Security & Testing

Enforces test-driven development practices through automated pre-commit hooks and CI coverage gates.

About

This skill automates the implementation of Test-Driven Development (TDD) workflows by configuring robust guardrails across the development lifecycle. It enables developers to set up pre-commit hooks that validate test presence for new code, establish CI gates that block PRs failing to meet coverage thresholds, and manage gradual TDD adoption for brownfield projects. By integrating with tools like Husky and GitHub Actions, it ensures high code quality and prevents regression by ensuring code cannot be merged without adequate test coverage.

Key Features

Automated pre-commit hook configuration for JS and Python
Test presence validation for new and modified files
67 GitHub stars
Configurable CI coverage gates for GitHub Actions
Multiple enforcement levels from 'Audit' to 'Strict'
Support for gradual TDD adoption in legacy codebases

Use Cases

Setting up a new project with strict TDD requirements
Adding coverage-based PR blocking to an existing CI pipeline
Ensuring all new code has corresponding tests in a brownfield project
