Estrategias de pruebas Python usando pytest, metodología TDD, fixtures, mocking, parametrización y requisitos de cobertura.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# Patrones de Pruebas Python
Estrategias completas de pruebas para aplicaciones Python usando pytest, metodología TDD y buenas prácticas.
## Cuándo Activar
- Escribir código Python nuevo (seguir TDD: rojo, verde, refactorizar)
- Diseñar suites de pruebas para proyectos Python
- Revisar la cobertura de pruebas Python
- Configurar infraestructura de pruebas
## Filosofía Central de Pruebas
### Desarrollo Guiado por Pruebas (TDD)
Siempre seguir el ciclo TDD:
1. **ROJO**: Escribir una prueba que falle para el comportamiento deseado
2. **VERDE**: Escribir el código mínimo para que la prueba pase
3. **REFACTORIZAR**: Mejorar el código manteniendo las pruebas en verde
```python
# Paso 1: Escribir prueba fallida (ROJO)
def test_add_numbers():
result = add(2, 3)
assert result == 5
# Paso 2: Escribir implementación mínima (VERDE)
def add(a, b):
return a + b
# Paso 3: Refactorizar si es necesario (REFACTORIZAR)
```
### Requisitos de Cobertura
- **Objetivo**: 80%+ de cobertura de código
- **Rutas críticas**: 100% de cobertura requerida
- Usar `pytest --cov` para medir la cobertura
```bash
pytest --cov=mypackage --cov-report=term-missing --cov-report=html
```

The line at the top of this page pins the label git:20260607.ac0f11c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
A 17 of 17 checks passed. Fixed automatic checks with no AI involved, so the same checks give the same answer every run.
