Testing Patterns

TDD workflow

1. Write a failing test (red)
2. Write minimal code to pass (green)
3. Refactor while keeping tests green

Vitest conventions

• Test files: *.test.ts next to source files
• Use describe / it blocks
• Prefer expect assertions
• Mock external dependencies, not internal logic
