Implementation Guidelines

• Pest/PHPUnit: Use Pest for DX or PHPUnit for legacy parity.
• TDD Flow: Follow Red-Green-Refactor cycle for new logic.
• Isolation: Mock dependencies via Mockery or PHPUnit mocks.
• Strict Assertions: Favor assertSame over assertTrue.
• Data Providers: Run tests against multiple sets via @dataProvider.
• Categorize: Separate Unit (isolated) from Integration (DB/API).

Anti-Patterns

• Testing Private: No Private Testing: Validate public behavior only.
• Over-Mocking: No Brittle Mocks: Mock system boundaries only.
• Blocking Tests: No Networking: Use in-memory DBs and mocks.
• Metric Chasing: No 100% Mania: Prioritize quality over coverage.
