# Shiplogic Integration Testing Guide

This guide explains how to test the Shiplogic API integration with mocked responses.

## Files Created

### 1. **routes/shiplogic-mock.php** - Mock API Endpoints
Routes that simulate the Shiplogic API responses for local testing without hitting the live API.

**Endpoints:**
- `POST /api/v1/mock/rates` - Returns available shipping rates/service levels
- `POST /api/v1/mock/shipments` - Returns created shipment confirmation
- `GET /api/v1/mock/shipments/label` - Returns waybill/label PDF
- `GET /api/v1/mock/shipments/label/stickers` - Returns sticker labels PDF

**To Enable:**
Add this line to `routes/web.php`:
```php
include base_path('routes/shiplogic-mock.php');
```

Then mock routes are available at `http://localhost:8000/api/v1/mock/*`

### 2. **app/Testing/ShiplogicMockClient.php** - Test Helper
PHP class for setting up HTTP mocking in tests. Uses Laravel's `Http::fake()` to intercept HTTP requests.

**Usage in Tests:**
```php
public function test_something()
{
    ShiplogicMockClient::setup();
    
    // Now all requests to shiplogic.* URLs will return mocked responses
    // Run your shipment creation logic here
}
```

### 3. **tests/Feature/ShipmentCreationTest.php** - Example Tests
Two example test cases demonstrating:
- End-to-end shipment creation workflow
- ECO service level selection verification

## Test Flow

### Local Testing with Mock Routes

1. **Start Laravel server:**
   ```bash
   php artisan serve
   ```

2. **Update CourierService.php** to point to mock endpoints temporarily:
   ```php
   // In CourierService.php constructor or config
   // Change: $this->baseUrl = config('services.shiplogic.api_base_url');
   // To test locally: $this->baseUrl = 'http://localhost:8000/api/v1/mock';
   ```

3. **Trigger shipment creation** via Filament UI or directly:
   ```php
   // Create an order
   $order = Order::factory()->create([...]);
   
   // Trigger ReadyToShipIntent event
   event(new App\Events\ReadyToShipIntent($order));
   ```

4. **Check logs** for detailed request/response logging:
   ```bash
   tail -f storage/logs/laravel.log
   ```

### Unit/Feature Testing with HTTP Mocking

1. **Run the test:**
   ```bash
   php artisan test tests/Feature/ShipmentCreationTest.php
   ```

2. **Test will:**
   - Mock all HTTP requests to shiplogic API
   - Create test order with required fields
   - Trigger shipment creation
   - Assert order has shipment metadata
   - Assert PDFs were stored locally

## Logging Details

The enhanced CourierService now logs at each stage:

### GET Rates Request
```
INFO: Fetching shipping rates from Shiplogic
  - order_uuid: 019b8335-4b47-7087-8b93-73f6aa39ee7a
  - api_url: https://api.shiplogic.com/rates
  - collection_address: {...}
  - delivery_address: {...}
  - parcel_dimensions: {...}
```

### GET Rates Response
```
INFO: Rates API response received
  - status: 200
  - successful: true

OR

ERROR: Rates API error response
  - status: 400 (or other error code)
  - error_message: Invalid address format
  - full_response: {...}
```

### CREATE Shipment Request
```
INFO: Creating Shiplogic shipment
  - order_uuid: 019b8335-4b47-7087-8b93-73f6aa39ee7a
  - order_number: ORDER-001
  - customer: John Doe
  - delivery_address: Apt 5B, 123 Main Street
  - service_level: FEDEX_INTERNATIONAL_ECONOMY
  - api_url: https://api.shiplogic.com/shipments
  - payload: {...}
```

### CREATE Shipment Response
```
INFO: Shipment created in API
  - shipment_id: 550e8400-e29b-41d4-a716-446655440002
  - tracking_reference: SHP123456789
```

## Debugging "Unknown Error"

If you see `ERROR: Failed to get shipping rates {"error":"Failed to fetch rates: Unknown error"}`:

1. **Enable detailed logging** - Now included in updated CourierService
2. **Check the full API response** - Logs will now show the actual error response
3. **Common issues:**
   - Invalid API key format
   - Missing required address fields
   - Invalid parcel dimensions
   - API endpoint URL incorrect
   - Network/SSL certificate issues

## Running Tests

```bash
# Run all shipment creation tests
php artisan test tests/Feature/ShipmentCreationTest.php

# Run specific test
php artisan test tests/Feature/ShipmentCreationTest.php::test_shipment_creation_with_mock_api

# Run with verbose output
php artisan test tests/Feature/ShipmentCreationTest.php -v

# Run and dump test database
php artisan test tests/Feature/ShipmentCreationTest.php --debug
```

## Mock Response Structure

All mock responses follow the actual Shiplogic API structure:

### Rates Response
```json
{
  "id": "550e8400-e29b-41d4-a716-446655440001",

}
```

## Next Steps

1. ✅ Add detailed logging to CourierService
2. ✅ Create mock API routes and test helper
3. **TODO:** Test with actual order to capture real error
4. **TODO:** Fix identified Shiplogic API integration issue
5. **TODO:** Verify PDFs are being fetched and attached correctly
