SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill helps developers implement Test-Driven Development (TDD) practices, ensuring code quality and maintainability by enforcing a strict RED → GREEN → REFACTOR cycle.

Core Features & Use Cases

RED → GREEN → REFACTOR Cycle: Ensures a failing test is written before any implementation, followed by passing the test with minimal code, and finally refactoring the code without breaking tests.
Use Case: Ideal for writing unit or integration tests, especially in testing-heavy stacks like React + Jest/Vitest, Python + pytest, Rails + RSpec, Go + testing package.

Quick Start

Start the TDD cycle by writing a failing test for your feature.

FAQPage Schema

How do I implement a test-first development workflow in my coding environment?▼

Test-first development is implemented by enforcing a strict RED → GREEN → REFACTOR cycle, requiring a failing test before any code implementation, followed by minimal code to pass, and then refactoring without breaking tests.

What is the RED → GREEN → REFACTOR cycle for unit tests?▼

The RED → GREEN → REFACTOR cycle is a TDD practice where you write a failing unit test, implement minimal code to make it pass, and then refactor the implementation while ensuring the tests continue to pass.

Does test-driven development work with React, Python, Rails, and Go stacks?▼

Test-driven development works with testing-heavy stacks like React with Jest or Vitest, Python with pytest, Rails with RSpec, and Go with the testing package, ensuring minimal code implementation and maintainable refactoring.

What's the best way to start writing integration tests using TDD practices?▼

The best way to start TDD for integration tests is to begin the cycle by writing a failing test for your feature, ensuring you only write implementation code after the test fails.

When should I not use test-driven development for my coding practices?▼

You should avoid strict test-driven development when working in environments without testing frameworks, as this practice requires a failing test before implementation and relies on test-heavy stacks like Jest, pytest, RSpec, or Go testing.

Can I use the tdd Skill to refactor code without breaking existing unit tests?▼

Yes, the tdd Skill implements Test-Driven Development practices that ensure you can refactor code without breaking tests by maintaining the RED → GREEN → REFACTOR cycle throughout your coding workflow.
