## When to Use - Implementar cambios en Python con garantía de comportamiento. - Escribir tests primero (TDD) para bugfixes o features. - Validar lambdas, integraciones AWS y CDK Step Functions. ## Critical Patterns 1. **TDD real: RED → GREEN → REFACTOR** - RED: test nuevo falla por la razón correcta. - GREEN: mínimo código para pasar. - REFACTOR: mejorar sin romper tests. - Si no hubo RED real, no fue TDD. 2. **Tests de runtime, no solo inspección de source** - Probar comportamiento observable (inputs/outputs/side effects). - Evitar tests que solo validan strings o AST sin ejecutar lógica. 3. **Mocking AWS: boto3/SES/Dynamo** - Mockear clientes boto3 en bordes del sistema. - Validar llamadas esperadas (payload, tabla, destinatarios, etc.). - No tocar recursos AWS reales en unit tests. 4. **CDK Step Functions: assertions de synth** - Synth de stack en test. - Assert sobre definición de State Machine y recursos esperados. - Verificar contratos críticos (timeouts, retries, permisos mínimos). 5. **Evidencia ejecutada obligatoria** - Guardar comando exacto corrido (`pytest ...`). - Guardar resultado (pass/fail + resumen). - No declarar “tested” sin ejecución real. ## Minimal TDD Loop ```text 1) Escribir test que falla (RED) 2) Implementar mínimo para pasar (GREEN) 3) Refactor seguro con suite verde (REFACTOR) 4) Registrar evidencia del run ``` ## Commands ```bash # Ejecutar subset rápido durante RED/GREEN pytest tests/unit/path/test_module.py -q # Ejecutar suite objetivo antes de cerrar pytest tests/unit -q ``` ## Resources - **Runtime tests**: `tests/unit/` - **Infra assertions**: `tests/unit/test_alerting_router_stack.py`
