SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill addresses the instability and lack of confidence in codebases by enforcing a rigorous Test-Driven Development (TDD) cycle, ensuring that every feature and bug fix is verified by automated tests before implementation.

Core Features & Use Cases

  • The Prove-It Pattern: Ensures bug fixes are verified by a reproduction test before the fix is applied, preventing regressions.
  • TDD Cycle Enforcement: Guides the agent through the Red-Green-Refactor loop to maintain high code quality.
  • Test Pyramid Strategy: Encourages a balanced testing approach, prioritizing fast, isolated unit tests over slower, brittle E2E tests.

Quick Start

Use the test-driven-development skill to guide the implementation of a new user authentication feature by first writing a failing test case.

FAQPage Schema
How does the Red-Green-Refactor cycle improve code reliability?▼

The Red-Green-Refactor cycle improves code reliability by enforcing a test-driven development loop where you first write a failing test, implement the minimum code to pass it, and then safely refactor without causing regressions.

What is the best way to prevent regressions when fixing a software bug?▼

To prevent regressions when fixing a bug, apply the Prove-It Pattern by writing a reproduction test that fails and confirms the bug, then apply the fix until the test passes successfully.

How do I start implementing a new feature using test-driven development?▼

Start implementing a new feature using test-driven development by writing a failing unit test case that defines the desired behavior, then write the implementation code required to make that test pass.

Should I prioritize unit tests or end-to-end tests for quality assurance?▼

For quality assurance, you should prioritize fast and isolated unit tests over slower, brittle end-to-end tests to maintain a balanced testing strategy and achieve reliable code verification.

Do I need a specific testing framework to use test-driven development?▼

No specific testing framework is required, as test-driven development utilizes your repository-specific testing frameworks and commands to execute the Red-Green-Refactor cycle within your existing environment.
