SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps teams enforce a strict test-first approach by guiding the creation and execution of tests before implementing production code, reducing defects and guiding design decisions.

Core Features & Use Cases

  • Enforces the Red-Green-Refactor cycle for each feature, ensuring a failing test is written first and that code changes stay minimal.
  • Provides clear enforcement rules to prevent coding before tests and to ensure one feature per iteration.
  • Includes a practical workflow for constructing and validating tests, reference strategies, and disciplined refactoring across common languages and tooling.

Quick Start

Start a TDD cycle by writing a failing test for the next feature, then implement the minimal code to make it pass.

FAQPage Schema
How do I enforce a strict test-driven development workflow for my team?▼

Test-driven development is enforced by guiding teams to write a failing test before implementing production code. This discipline reduces defects and drives design decisions through a strict Red-Green-Refactor cycle.

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

The Red-Green-Refactor cycle is a test-driven development workflow requiring a failing test first, implementing minimal code to pass it, and then refactoring. It ensures code changes stay minimal and features are isolated per iteration.

How to start a TDD cycle when adding a new software feature?▼

Start a TDD cycle by writing a failing test for the next feature, then implement the minimal production code required to make that test pass. This test-first approach ensures structured guidance and validates test quality.

Can I use test-driven development across different programming languages and tooling?▼

Test-driven development applies to software development workflows across languages. It provides a practical workflow for constructing and validating tests, alongside reference strategies for disciplined refactoring with common tooling.

Why should I write tests before implementing production code?▼

Writing tests before implementing production code reduces defects and guides design decisions. This test-first approach enforces single-feature test isolation and outputs structured guidance for evaluating test quality.

What are the limitations of enforcing a test-first approach for software testing?▼

The main limitation of a test-first approach is the strict requirement to adhere to the Red-Green-Refactor workflow. It prevents coding before tests and limits iterations to one feature, requiring disciplined adherence to test strategy.
