What problem does it solve? Writing Laravel tests that actually catch defects is hard: tests often assert framework behavior, duplicate coverage, depend on real time or network, or pass while providing no value. This Skill provides a structured rule set for designing, writing, and reviewing PHPUnit-based Laravel tests so every test detects a distinct defect. ## Core Features & Use Cases - Test Design Rules: Nine rule files covering naming, assertions, endpoint coverage, test data, isolation with fakes and mocks, security boundaries, and suite performance. - Test Review Checklist: A systematic review process that checks test value, coverage, determinism, and assertion quality before completion. - Use Case: When adding a new API endpoint to a Laravel application, use this Skill to write feature tests covering authentication, authorization, validation, tenant isolation, and persisted state, then review them against the checklist. ## Quick Start Ask the agent to write tests for a Laravel controller or review an existing test suite using the testing best practices rules.
