SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill streamlines the process of implementing or modifying code by enforcing a rigorous test-driven development (TDD) loop, ensuring changes are validated with targeted tests and checks.

Core Features & Use Cases

  • Test-Driven Development: Implement changes in small, testable increments (Red -> Green -> Refactor).
  • Automated Verification: Integrates with existing test suites and linting tools for continuous validation.
  • Use Case: When a bug is reported or a new feature is requested, use this Skill to write a failing test, implement the minimal code to pass it, and then refactor, ensuring the fix is robust and well-tested.

Quick Start

Use the tdd-loop skill to implement the requested behavior change by writing a new failing test first.

FAQPage Schema
How do I enforce a test-driven development workflow when fixing bugs or adding features?

A test-driven development workflow ensures behavior changes and bug fixes are validated by writing a failing test first, then implementing minimal code to pass it, and finally refactoring with continuous linting and smoke checks.

What is the Red-Green-Refactor cycle in iterative code development?

The Red-Green-Refactor cycle in iterative code development involves writing a failing test, implementing the minimal code required to make it pass, and then refactoring the code while keeping tests green.

How do I validate code changes without mocking dependencies during refactoring?

Validating refactoring without mocking dependencies involves enforcing guardrails that prefer assertions on observable behavior, ensuring targeted tests validate actual outputs rather than mocked interactions.

Can I run targeted tests and broader project checks incrementally during agile development?

Yes, you can run targeted tests and broader project checks incrementally by using specific verification commands that execute focused test suites and linting tools continuously throughout the development loop.

Does test-driven development work with existing test suites and linting tools?

Test-driven development works with existing test suites and linting tools by integrating automated verification commands that execute targeted tests and broader project checks during each iterative code modification step.

Why should I use a strict TDD loop instead of writing tests after implementation?

A strict TDD loop ensures behavior changes are validated upfront by writing failing tests first, preventing over-engineering and ensuring robust, well-tested refactors through continuous automated verification before code is finalized.
