SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps teams ensure production-ready features by enforcing a test-first approach, guaranteeing that a failing test exists before writing production code.

Core Features & Use Cases

Red-Green-Refactor cycle guidance for Python (pytest) and Go projects.
Spec-aware development workflow guidance, with concrete RED/GREEN/REFACTOR steps and anti-pattern awareness.
References to essential patterns and templates for test strategy, with embedded examples and best practices.

Quick Start

Start by writing a failing test that captures the intended behavior, then implement the minimal code to make the test pass, and finally refactor for clarity and maintainability.

FAQPage Schema

How do I enforce test-first development before writing production code?▼

Test-first development is enforced by ensuring a failing test exists before any production code is written, driving features through a strict Red-Green-Refactor workflow. This approach guarantees minimal implementations designed by clear failures.

What is the Red-Green-Refactor cycle in test-driven development?▼

The Red-Green-Refactor cycle starts by writing a failing test capturing intended behavior, then implementing minimal code to pass the test, and finally refactoring for clarity. It guides Python and Go projects toward maintainable, spec-aware outputs.

How do I start TDD with pytest for Python feature work?▼

Start TDD with pytest by writing a failing test that defines the desired feature behavior. Apply minimal production code to pass the test, then refactor for clarity. This ensures spec-aware, failure-driven design across Python projects.

Does test-driven development work for bug fixes and refactoring in Go projects?▼

Test-driven development works for bug fixes and refactoring in Go projects by applying the Red-Green-Refactor cycle. It ensures a failing test exists before patches, promoting minimal, test-driven implementations with clear failure-driven design.

Why should I use a spec-aware TDD workflow for software testing?▼

A spec-aware TDD workflow should be used to maintain strict guardrails during software testing. It provides concrete Red-Green-Refactor steps and anti-pattern awareness, ensuring production-ready features through failure-driven design and minimal implementations.

When should I not use test-driven development for engineering workflows?▼

Test-driven development may not suit engineering workflows requiring rapid prototyping without spec certainty. The strict Red-Green-Refactor discipline enforces failing tests before production code, which can delay initial feature exploration in Python or Go projects.
