Testing Trophy

Testing philosophy for React and TypeScript projects. Based on Kent C. Dodds' Testing Trophy and TkDodo's testing principles.

Testing Trophy Priorities

From most to least valuable:

1. Integration tests — test multiple units working together (highest confidence per effort)
2. Unit tests — test individual functions in isolation
3. End-to-end tests — test full user flows (highest confidence, highest cost)
4. Static analysis — TypeScript, ESLint (cheapest, catches typos and type errors)

"The more your tests resemble the way your software is used, the more confidence they can give you." — Kent C. Dodds

Core Principles

1. Test behavior, not implementation
