SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Poorly written tests (too many, too few, or focused on implementation details) lead to brittle code, slow feedback loops, and missed bugs. This Skill guides strategic test writing, ensuring your tests are effective, fast, and maintainable.

Core Features & Use Cases

  • Strategic Test Writing: Focuses on core user flows and critical business paths.
  • Unit & Integration Tests: Guides the creation of appropriate test types for different scopes.
  • Mocking External Dependencies: Teaches how to isolate code for faster, more reliable tests.
  • Use Case: After implementing a new user authentication service, use this Skill to write integration tests for the login and registration flows, and unit tests for critical password hashing logic, deferring minor edge cases.

Quick Start

Write strategic unit tests for the new ShoppingCart class, focusing on adding items, removing items, and calculating the total, mocking any external database calls.
