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.

Aplique la filosofía de prueba: pruebe el comportamiento, no la implementación, minimice las simulaciones, estructura AAA, cobertura para confianza, no porcentaje. Úselo al redactar exámenes, revisar la calidad de los exámenes, discutir TDD o evaluar estrategias de exámenes. Fuente: phrazzld/claude-config.
