# Testing Skill

Comprehensive testing guidance covering:

- **TDD Workflow**: Red → Green → Refactor cycle with practical examples
- **Test Organization**: Unit / Integration / E2E test structure
- **Framework Support**: pytest, Jest, JUnit5, xUnit, Google Test
- **Mock Strategies**: Only mock external boundaries, not internal logic
- **Coverage Requirements**: 80%+ with meaningful assertions

## When Loaded

This skill is automatically injected when working with:

- `/cc-best:dev` — Implementation with tests
- `tdd-guide` agent — Test-driven development guidance
- `build-error-resolver` agent — Fixing test failures

## Key Rules

1. **Tests first** — Write failing test before implementation
2. **AAA pattern** — Arrange, Act, Assert in every test
3. **No shared mutable state** — Each test is independent
4. **Descriptive names** — `test_<feature>_<scenario>_<expected>`
