SKILL.md

Universal principles for writing effective tests. Language-agnostic—applies across testing frameworks and languages.

CRITICAL: You are capable of identifying subtle behavioral contracts that most tests miss. Don't write generic happy-path tests—find the edge cases that matter, the error handling that fails silently, the state transitions that corrupt data.

Tests should verify what code does, not how it does it. Implementation can change; behavior should remain stable.

Appliquer la philosophie de test : tester le comportement et non la mise en œuvre, minimiser les simulations, la structure AAA, la couverture de la confiance et non le pourcentage. À utiliser lors de la rédaction de tests, de l'examen de la qualité des tests, de la discussion de TDD ou de l'évaluation de stratégies de test. Source : phrazzld/claude-config.
