SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps teams replace guesswork with a disciplined test-first process, making requirements clearer and reducing defects while developing software.

Core Features & Use Cases

  • RED-GREEN-REFACTOR guidance: Follow a repeatable cycle for writing failing tests, implementing minimal code, and improving design safely.
  • Test design support: Focus on behavior, edge cases, error states, and AAA structure so tests act as living specifications.
  • Use Case: When building a new feature or fixing a bug, use this Skill to define the expected behavior first, implement only what is necessary, and refactor without breaking coverage.

Quick Start

Use the tdd-workflow skill to turn your next feature request into a failing test first, then implement the smallest change that makes it pass.

FAQPage Schema
What is the red-green-refactor cycle in test-driven development?

Test-driven development replaces guesswork with a test-first process by turning requirements into failing tests that define expected behavior first, then implementing only the minimal code necessary to make the test pass safely.

How do I use TDD to fix a bug in existing software?

To use TDD for a bug fix, write a failing unit test that reproduces the specific error state, implement the smallest change to make the test pass, and refactor the logic while ensuring the behavior remains locked by the new test.

Can I apply test-first development to exploratory spikes and complex logic?

Yes, test-first development applies to new features, bug fixes, and exploratory spikes by enforcing the AAA test structure to define edge cases and error states, ensuring complex logic acts as a living specification.

What is the best way to structure unit tests for behavior and edge cases?

The best way to structure unit tests is using the AAA structure, prioritizing tests that focus on specific behavior, edge cases, and error states so the tests act as living specifications rather than simple implementation checks.

When should I avoid the test-driven development workflow?

You should avoid the test-driven development workflow when requirements are completely undefined or when performing trivial changes where the overhead of writing failing tests first provides no behavioral specification value.
