## Testing {#feature-services-testing}

### Unit tests {#feature-services-testing-unit}

**Run feature service tests**

```bash
# Run all unit tests
Build/Scripts/runTests.sh -s unit

# Alternative: Via Composer script
composer ci:test:php:unit
```

### Mocking services {#feature-services-testing-mocking}

**Example: Mocking feature services in tests**

```php
use Netresearch\NrLlm\Service\Feature\VisionServiceInterface;
use PHPUnit\Framework\TestCase;

class YourServiceTest extends TestCase
{
    public function testImageEnhancement(): void
    {
        $visionMock = $this->createMock(VisionServiceInterface::class);
        $visionMock->method('generateAltText')
            ->willReturn('Test alt text');

        $service = new YourService($visionMock);
        $result = $service->enhanceImage('https://example.com/test.jpg');

        $this->assertEquals('Test alt text', $result['alt']);
    }
}
```
