SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill codifies the practice of Test-Driven Development to prevent production code without failing tests, reducing defects and ensuring safer changes across codebases.

Core Features & Use Cases

  • Test-first integrity: require a failing test before any production code is written.
  • Red-Green-Refactor guidance: step-by-step workflow, concrete examples, and templates to apply TDD in real projects.
  • Onboarding and standards: prompts and checklists to orient new team members and maintain consistency across features and modules.

Quick Start

Begin by writing a small failing test for a trivial function, implement the minimal production code to pass the test, and then refactor for clarity while keeping tests green. Apply the same cycle to real features in your codebase to build confidence.

FAQPage Schema
How do I enforce test-first discipline in TypeScript projects?

Test-driven development requires writing a failing test before any production code, ensuring the red-green-refactor cycle guides minimal implementation and safer refactoring across TypeScript software projects.

What is the red-green-refactor cycle and how do I apply it?

The red-green-refactor cycle starts by writing a failing test, implementing minimal production code to pass it, and refactoring for clarity while keeping tests green, ensuring continuous test-first integrity across software projects.

Can I use test-driven development for both unit and integration tests?

Yes, test-driven development applies to both unit and integration workflows across small features and complex TypeScript systems, ensuring mandatory test failure visibility before writing production code.

Does test-driven development work for refactoring existing JavaScript codebases?

Yes, test-driven development includes refactoring safeguards that guide clarity improvements while keeping tests green, providing templates and checklists to maintain consistency when modifying existing JavaScript codebases.

When should I not use test-driven development?

Avoid strict test-driven development for rapid prototypes without defined behavior, as it mandates a failing test before any production code. It is best suited for features and modules requiring defect reduction and safer changes.
