## 3. Verificacion de Casos de Cobertura Requeridos

### 3.1 Journal Entries Balance Validation (debits = credits)

| Caso | Estado | Ubicacion |
|------|--------|-----------|
| Crear poliza balanceada | CUBIERTO | `journal-entries.service.spec.ts` - describe('create') |
| Rechazar poliza desbalanceada | CUBIERTO | Test: 'should throw ValidationError when entry is not balanced' |
| Validar balance al publicar | CUBIERTO | Test: 'should throw ValidationError when posting unbalanced entry' |
| Validar balance en actualizacion | CUBIERTO | Test: 'should validate balance when updating lines' |
| Tolerancia de 0.01 | CUBIERTO | Implementado con `Math.abs(totalDebit - totalCredit) > 0.01` |

**Tests especificos:**
```typescript
// Linea 720-727: Validacion de balance desbalanceado
it('should throw ValidationError when entry is not balanced', async () => {
  const dto = {
    ...
    lines: [
      { accountId: 'acc-1', debit: 1000, credit: 0 },
      { accountId: 'acc-2', debit: 0, credit: 500 }, // Unbalanced
    ],
  };
  await expect(...).rejects.toThrow(ValidationError);
});
```

### 3.2 Invoice Workflow (draft -> posted -> paid)

| Transicion | Estado | Detalle |
|------------|--------|---------|
| draft -> open (validate) | CUBIERTO | Test: 'should validate draft invoice and generate number' |
| open -> paid | PARCIAL | Logica existe en `payments.service.ts` pero SIN tests |
| draft -> cancelled | CUBIERTO | Test: 'should cancel open invoice successfully' |
| paid -> cancelled | CUBIERTO | Test: 'should throw ValidationError when cancelling paid invoice' |

**Estados de Invoice cubiertos:**
- `DRAFT` - Estado inicial
- `OPEN` - Despues de validate()
- `PAID` - Cuando amountResidual = 0 (via payment reconciliation)
- `CANCELLED` - Despues de cancel()

**Tests especificos:**
```typescript
// Linea 1023-1055: Validacion de factura (draft -> open)
describe('validate', () => {
  it('should validate draft invoice and generate number (customer)', ...);
  it('should generate BILL- prefix for supplier invoice', ...);
  it('should throw ValidationError when validating invoice without lines', ...);
  it('should throw ValidationError when validating non-draft invoice', ...);
});

// Linea 1121-1191: Cancelacion de factura
describe('cancel', () => {
  it('should cancel open invoice successfully', ...);
  it('should throw ValidationError when cancelling paid invoice', ...);
  it('should throw ValidationError when cancelling already cancelled invoice', ...);
  it('should throw ValidationError when cancelling invoice with payments', ...);
});
```

### 3.3 Payment Reconciliation

| Caso | Estado | Ubicacion |
|------|--------|-----------|
| Reconciliar pago con factura | SIN TESTS | Logica en `payments.service.ts` lineas 443-556 |
| Validar monto no excede pago | SIN TESTS | Implementado pero sin tests |
| Validar factura pertenece al mismo partner | SIN TESTS | Implementado pero sin tests |
| Validar factura esta en estado OPEN | SIN TESTS | Implementado pero sin tests |
| Actualizar amountPaid y amountResidual | SIN TESTS | Implementado pero sin tests |
| Cambiar status a PAID cuando residual = 0 | SIN TESTS | Implementado pero sin tests |
| Revertir reconciliacion al cancelar pago | SIN TESTS | Implementado pero sin tests |

**Funcionalidad existente sin tests:**
- `paymentsService.reconcile()` - Lineas 443-556
- `paymentsService.cancel()` - Lineas 562-637

### 3.4 Multi-currency Handling

| Caso | Estado | Ubicacion |
|------|--------|-----------|
| Campo currencyId en Invoice | EXISTE | `invoice.entity.ts` linea 70-71 |
| Campo currencyId en Payment | EXISTE | `payment.entity.ts` |
| Campo currencyId en Account | EXISTE | `account.entity.ts` |
| Conversion de moneda | NO IMPLEMENTADO | No hay servicio de conversion |
| Tests de multi-moneda | NO EXISTEN | Sin cobertura de tests |

**Analisis:**
- Los campos de moneda existen en las entidades
- Se almacena `currencyId` en invoices, payments y accounts
- NO hay logica de conversion de tasas de cambio
- NO hay tests que verifiquen comportamiento multi-moneda

### 3.5 Lock Date Enforcement

| Caso | Estado | Ubicacion |
|------|--------|-----------|
| Campo lockDate | NO EXISTE | No hay campo de fecha de bloqueo |
| Validacion de fecha de bloqueo | NO IMPLEMENTADO | Sin logica |
| Tests de lock date | NO EXISTEN | Sin cobertura |

**Analisis:**
- El modulo usa `FiscalPeriod` con estados OPEN/CLOSED
- Existe `closePeriod()` y `reopenPeriod()` en `fiscalPeriods.service.ts`
- La validacion de periodo cerrado NO esta conectada a journal entries
- No hay enforcement de "lock date" al crear/modificar polizas

**Alternativa implementada:**
- `FiscalPeriod` tiene estados: `OPEN`, `CLOSED`
- `closePeriod()` usa funcion de base de datos `financial.close_fiscal_period()`
- Falta conectar la validacion al servicio de journal entries

## 6. Recomendaciones

### 6.1 Prioridad Alta (Siguiente Sprint)

1. **Crear `payments.service.spec.ts`**
   - Tests para CRUD de pagos
   - Tests para reconciliacion de pagos con facturas
   - Tests para cancelacion y reversion de reconciliacion

2. **Completar workflow Invoice -> Paid**
   - Agregar tests de integracion para el flujo completo
   - Verificar actualizacion de amountPaid y amountResidual

### 6.2 Prioridad Media

3. **Implementar Lock Date Enforcement**
   - Agregar campo `lockDate` a Company o FiscalYear
   - Validar en `journalEntriesService.create()` y `update()`
   - Crear tests para la validacion

4. **Tests para Multi-currency**
   - Implementar servicio de conversion de moneda
   - Tests para operaciones en diferentes monedas

### 6.3 Prioridad Baja

5. **Crear tests para servicios auxiliares:**
   - `taxes.service.spec.ts`
   - `journals.service.spec.ts`
   - `fiscalPeriods.service.spec.ts`

---

## 7. Patron de Tests Utilizado

Los tests existentes siguen un patron consistente:

```typescript
// 1. Factory functions para datos de prueba
import { createInvoice, createTenant, ... } from 'tests/factories';

// 2. Mock de dependencias
jest.mock('../../../config/typeorm', ...);
jest.mock('../../../shared/utils/logger', ...);

// 3. Estructura describe/it con beforeEach para reset
describe('ServiceName', () => {
  beforeEach(() => {
    resetFactoryCounters();
    jest.clearAllMocks();
    // Setup mocks
  });

  describe('methodName', () => {
    it('should ...', async () => {
      // Arrange
      // Act
      // Assert
    });
  });
});
```

---

## 8. Conclusion

El modulo Financial tiene una **cobertura de tests solida para sus servicios principales** (Accounts, Invoices, Journal Entries) con 91 tests unitarios. Sin embargo, hay **gaps importantes** en:

1. **PaymentsService** - Sin tests a pesar de tener logica compleja de reconciliacion
2. **Lock Date Enforcement** - No implementado
3. **Multi-currency** - Campos existen pero sin logica de conversion

La arquitectura de tests es madura y utiliza factories apropiadas, lo que facilitara agregar los tests faltantes siguiendo el patron establecido.
