## Controller Methods Coverage

### 1. **index()** (Public) - 7 test cases ✓

| Scenario | Test Case | Status |
|----------|-----------|--------|
| Returns brand models list | `test_index_returns_brand_models` | ✓ PASS |
| Paginated response | `test_index_returns_paginated_list` | ✓ PASS |
| Filter by status | `test_index_filters_by_status` | ✓ PASS |
| Search by name_en | `test_index_searches_by_name_en` | ✓ PASS |
| Search by name_fr | `test_index_searches_by_name_fr` | ✓ PASS |
| Multiple filters combined | `test_index_with_multiple_filters` | ✓ PASS |
| Pagination page 2 | `test_index_pagination_page_2` | ✓ PASS |
| No models in database | `test_index_with_no_models` | ✓ PASS |

**Coverage**: Pagination, filtering (status), search (en/fr), sorting

---

### 2. **show()** (Public) - 3 test cases ✓

| Scenario | Test Case | Status |
|----------|-----------|--------|
| Returns model detail | `test_show_returns_brand_model_detail` | ✓ PASS |
| 404 for non-existing model | `test_show_returns_404_for_non_existent_model` | ✓ PASS |
| Returns all model fields | `test_show_returns_all_model_fields` | ✓ PASS |

**Coverage**: Single model retrieval, not found handling, response structure

---

### 3. **store()** (Protected - Admin JWT) - Not Tested
**Note**: Protected endpoints require admin JWT authentication. See README for integration test setup.

---

### 4. **update()** (Protected - Admin JWT) - Not Tested
**Note**: Protected endpoints require admin JWT authentication. See README for integration test setup.

---

### 5. **destroy()** (Protected - Admin JWT) - Not Tested
**Note**: Protected endpoints require admin JWT authentication. See README for integration test setup.

| Protected Endpoints (Requires JWT) | 3 (store, update, destroy) |
| Total Test Cases | 15 |
| Total Assertions | 27 |

## Feature Coverage

### Implemented Features (Public Endpoints)
- ✓ List brand models with pagination
- ✓ Filter by status (active, inactive)
- ✓ Search by name_en (English name)
- ✓ Search by name_fr (French name)
- ✓ Sorting by name
- ✓ Get model detail by ID
- ✓ 404 handling for non-existent models

### Brand Model Properties

| Field | Type | Enum Values |
|-------|------|-------------|
| id | Integer | Auto |
| brand_id | Integer | Foreign Key (brands.id) |
| name_en | String | - |
| name_fr | String | - |
| status | String | 'active', 'inactive' |
| created_at | Timestamp | Auto |
| updated_at | Timestamp | Auto |

### Status Values
- ACTIVE = 'active'
- INACTIVE = 'inactive'

---

## Endpoint Coverage

| Endpoint | Method | Auth | Route | Tests | Status |
|----------|--------|------|-------|-------|--------|
| List Models | GET | No | /api/v1/models | 8 | ✓ Tested |
| Show Model | GET | No | /api/v1/models/{id} | 3 | ✓ Tested |
| Create Model | POST | Admin JWT | /api/v1/admin/models | - | ⚠ Not Tested |
| Update Model | PUT | Admin JWT | /api/v1/admin/models/{id} | - | ⚠ Not Tested |
| Delete Model | DELETE | Admin JWT | /api/v1/admin/models/{id} | - | ⚠ Not Tested |
| **Total Tested** | | | | **11** | |

---

## Integration Tests

### Multi-Step Scenarios
- ✓ Multiple models from same brand
- ✓ Models from different brands
- ✓ Search with partial match
- ✓ Case-insensitive search

---

## Known Limitations

### Protected Endpoint Testing
Protected endpoints (store, update, destroy) require admin JWT authentication token. Current test setup:
- Focus is on public endpoints (list and show)
- Admin endpoints would require JWT setup in future integration tests

### Search Implementation
- Search works on both name_en and name_fr fields
- Partial matching supported
- Case-insensitive matching supported

---

## Running the Tests

```bash
# Run all brand model tests
php artisan test tests/Feature/API/Admin/BrandModelControllerTest.php

# Run specific test
php artisan test tests/Feature/API/Admin/BrandModelControllerTest.php --filter test_index_returns_brand_models

# Run with coverage report
php artisan test tests/Feature/API/Admin/BrandModelControllerTest.php --coverage

# Run with verbose output
php artisan test tests/Feature/API/Admin/BrandModelControllerTest.php -v
```

---

## Test Execution Requirements

- Laravel 11+ (Framework version in use)
- PHPUnit 11.5+
- PHP 8.2+
- Test database configured
- Models table must exist with proper schema

---

## Recommendations for Complete Coverage

### Add Admin JWT Tests
To test protected endpoints, create authenticated tests:
```php
public function test_store_creates_model_as_admin(): void
{
    $admin = $this->createAdminUser();
    $headers = $this->authHeadersForAdmin($admin);
    $brand = $this->createBrand();
    
    $response = $this->postJson('/api/v1/admin/models', [
        'brand_id' => $brand->id,
        'name_en' => 'New Model',
        'name_fr' => 'Nouveau Modèle',
        'status' => BrandModelStatusEnum::ACTIVE->value,
    ], $headers);
    
    $response->assertStatus(Response::HTTP_OK);
}
```
