## 4. Casos de Prueba Faltantes

### 4.1 Prioridad ALTA - Tenant Isolation

```typescript
// FALTANTE: Tests de aislamiento entre tenants
describe('Tenant Isolation', () => {
  it('should prevent access to data from other tenants');
  it('should isolate user queries by tenantId');
  it('should isolate company queries by tenantId');
  it('should isolate role queries by tenantId');
  it('should prevent subdomain collision during update');
});
```

**Razon:** El aislamiento multi-tenant es critico para la seguridad. Actualmente solo se verifica indirectamente a traves de queries con tenantId, pero no hay tests explicitos que validen que un tenant no puede acceder a datos de otro.

### 4.2 Prioridad ALTA - Tests de Integracion

```typescript
// FALTANTE: tenants.integration.spec.ts
describe('Tenants Integration Tests', () => {
  describe('Complete Tenant Lifecycle', () => {
    it('should complete flow: create -> configure -> add users -> suspend -> activate -> delete');
  });

  describe('Multi-tenant scenarios', () => {
    it('should handle concurrent tenant operations');
    it('should maintain data isolation during concurrent access');
  });

  describe('Plan Upgrade/Downgrade', () => {
    it('should upgrade plan and increase limits');
    it('should prevent downgrade when exceeding new limits');
  });
});
```

**Razon:** Siguiendo el patron de `auth/__tests__/auth.integration.spec.ts`, deberia existir un archivo `tenants.integration.spec.ts` que pruebe flujos completos end-to-end.

### 4.3 Prioridad MEDIA - Feature Flags Avanzados

```typescript
// FALTANTE: Tests avanzados de feature flags
describe('Feature Flags Advanced', () => {
  it('should validate feature flag keys format');
  it('should prevent reserved feature flag names');
  it('should cascade feature flag inheritance from plan');
  it('should handle feature flag conflicts during merge');
});
```

### 4.4 Prioridad MEDIA - Validaciones Adicionales

```typescript
// FALTANTE: Validaciones de limites y constraints
describe('Limit Validations', () => {
  it('should prevent maxUsers below current user count');
  it('should prevent maxStorageMb below current usage');
  it('should validate trial period boundaries (min/max days)');
  it('should handle subscription expiration transitions');
});
```

### 4.5 Prioridad BAJA - Edge Cases

```typescript
// FALTANTE: Casos borde
describe('Edge Cases', () => {
  it('should handle unicode in tenant name');
  it('should normalize subdomain to lowercase');
  it('should handle very long tenant names (255 chars)');
  it('should handle empty metadata object');
  it('should handle null vs undefined for optional fields');
});
```

## 7. Recomendaciones

### 7.1 Acciones Inmediatas

1. **Crear `tenants.integration.spec.ts`**
   - Seguir el patron de `auth.integration.spec.ts`
   - Incluir flujo completo de lifecycle del tenant
   - Probar escenarios multi-tenant

2. **Agregar tests de Tenant Isolation**
   - Verificar que queries filtran por tenantId
   - Probar acceso cruzado entre tenants (debe fallar)
   - Validar aislamiento de schemas

### 7.2 Acciones a Mediano Plazo

3. **Expandir tests de Feature Flags**
   - Validacion de formatos
   - Herencia de flags por plan
   - Conflictos de merge

4. **Agregar validaciones de limites**
   - Prevenir reduccion de limites por debajo del uso actual
   - Transiciones de estado de suscripcion

### 7.3 Mejoras Continuas

5. **Agregar edge cases**
   - Unicode, longitudes maximas, valores nulos
   - Casos de concurrencia

---

## 8. Conclusion

El modulo `tenants` tiene una cobertura de tests **buena** (76%), pero presenta **gaps criticos** en:

1. **Tests de integracion** - No existe archivo `tenants.integration.spec.ts`
2. **Tests de aislamiento multi-tenant** - Critico para seguridad
3. **Feature flags avanzados** - Cobertura parcial

Se recomienda priorizar la creacion de tests de integracion y aislamiento antes de continuar con otras funcionalidades del modulo.
