SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires verification-before-completion@^1.0.0, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill helps developers enforce strict test-driven development, ensuring code quality and reliability by requiring tests before production code is written.

Core Features & Use Cases

  • Iron Law of TDD: Enforces the rule that no production code is written without a failing test first.
  • Red-Green-Refactor Cycle: Guides the process of writing tests, making the test pass, and refactoring the code.
  • Test Pyramid: Encourages a balanced suite of tests covering different levels of granularity.
  • Prove-It Pattern for Bugs: Ensures bug fixes are accompanied by a test that proves the fix works.
  • Use Case: Ideal for developers implementing new features, fixing bugs, or refactoring code to ensure it adheres to best practices.

Quick Start

Run 'codehands tdd' to start a new TDD cycle.

Frequently Asked Questions about test-driven-development

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I enforce test-driven development workflows for new feature implementation?▼

Test-driven development workflows are enforced by strictly applying the Iron Law: no production code is written without a failing test first. This ensures new features are built with quality assurance and structured coding practices.

What is the red-green-refactor cycle and how does it guide bug fixing?▼

The red-green-refactor cycle guides bug fixing by first writing a failing test that proves the bug exists (red), making the test pass (green), and then refactoring the code. This Prove-It Pattern ensures fixes are verifiable.

How do I maintain a balanced test pyramid during refactoring?▼

A balanced test pyramid during refactoring is maintained by encouraging a comprehensive suite of tests covering different levels of granularity, ensuring quality assurance across the entire codebase while adhering to strict TDD rules.

What's the best way to start a TDD cycle for a new coding task?▼

The best way to start a TDD cycle is to run the 'codehands tdd' command. This initiates the structured test-driven development process, enforcing the rule that production code is always accompanied by failing tests.

Can I use this strict TDD approach for both bug fixes and refactoring processes?▼

Yes, this strict TDD approach is ideal for both bug fixes and refactoring processes. It targets developers engaged in these tasks by utilizing structured coding practices and the Prove-It Pattern to ensure code reliability.

Does the TDD workflow require verification before completion?▼

Yes, the TDD workflow requires verification before completion to ensure quality assurance. This dependency guarantees that all production code is accompanied by failing tests and validated before finalizing the implementation.
