3. **View Counter**
   - ✅ Increments `blog_views` on each public access
   - ✅ Uses `$blog->increment('blog_views')`

4. **Image Replacement**
   - ✅ Deletes old image when new image uploaded
   - ✅ Uses `Storage::disk('public')->delete($blog->image)`

5. **Status Toggle**
   - ✅ Quick toggle endpoint for status changes
   - ✅ Returns updated blog data

6. **Filtering & Search**
   - ✅ Filter by category
   - ✅ Filter by status

## Test Sequence Validation

### Linear Task Requirements vs Implementation:

| # | Test Case | Endpoint | Status | Notes |
|---|-----------|----------|--------|-------|
| 1 | Get categories | `GET /api/admin/blog-categories` | ✅ | Requires auth |
| 2 | Create blog (with image) | `POST /api/admin/blogs` | ✅ | Image upload works |
| 3 | List blogs | `GET /api/admin/blogs` | ✅ | Pagination & filters |
| 4 | Update blog | `POST /api/admin/blogs/{id}` | ✅ | Image replacement |
| 5 | Toggle status | `POST /api/admin/blogs/{id}/toggle-status` | ✅ | Quick toggle |
| 6 | Public view | `GET /api/blogs/{slug}` | ✅ | Increments views |

## Code Quality Review

### ✅ Best Practices Followed:

1. **Error Handling**
   ```php
   try {
       // Logic
   } catch (\Exception $e) {
       return response()->json([
           'success' => false,
           'message' => 'Failed to...',
           'error' => config('app.debug') ? $e->getMessage() : 'Internal server error'
       ], 500);
   }
   ```

2. **Validation**
   ```php
   $validator = Validator::make($request->all(), [
       'category_id' => 'required|integer|exists:blog_categories,id',
       'title' => 'required|string|max:255',
       'image' => 'required|image|mimes:jpeg,png,jpg,gif|max:2048',
       ...
   ]);
   ```

3. **Resource Cleanup**
   - Deletes old images before saving new ones
   - Deletes images when blog is deleted

4. **Security**
   - File type validation
   - File size limits
   - Protected admin endpoints with JWT auth

## Next Steps for Full Testing

### Prerequisites Required:

1. **Database Setup**
   - Ensure blog categories exist in database
   - Run migrations if needed
   - Verify `blog_categories` and `blogs` tables exist

2. **Storage Setup**
   - Run `php artisan storage:link`
   - Verify `storage/app/public/blogs/` directory exists
   - Check write permissions

3. **Admin Account**
   - Create admin user if not exists
   - Get valid credentials for authentication

### Running the Tests:

#### **Option 1: Manual Testing with curl**
```bash
# Follow the detailed guide
cat tests/BLOG_API_MANUAL_TEST.md

# Run each curl command step-by-step
# Estimated time: 15 minutes
```

#### **Option 2: Automated PHP Test**
```bash
# Edit credentials in tests/BlogApiTest.php
# Line 92-95: Set valid admin email/password

php tests/BlogApiTest.php
# Estimated time: 2 minutes
```

#### **Option 3: Postman/Insomnia**
```bash
# Import the test collection from the manual guide
# Visual testing with better error handling
# Estimated time: 10 minutes
```
