Testing Philosophy

Core Principles

1. Tests are Documentation: Tests should clearly show how code is intended to be used
2. Test Behavior, Not Implementation: Focus on what the code does, not how
3. Arrange-Act-Assert: Structure tests with clear setup, execution, and verification
4. One Concept Per Test: Each test should verify a single behavior
5. Fast and Isolated: Tests should run quickly and independently
