# Testing and deployment

## Testing

### Current Test Setup

The project currently has limited automated tests. Main test file:
- `referral_system_test.js` - Tests for referral system calculations

### Running Tests

```bash
npm test
```

### Manual Testing

1. **Use Postman/Insomnia**
   - Import OpenAPI spec from `docs/openapi.json`
   - Test endpoints manually

2. **Use Scalar API Reference**
   - Access `http://localhost:3610/api/kitab-suci` in development
   - Test directly from browser

3. **WebSocket Testing**
   - Use Socket.IO client library
   - Or use tools like Socket.IO Client Tool

### Recommended Test Coverage

Future test implementation should cover:
- Unit tests for utilities and services
- Integration tests for API endpoints
- E2E tests for critical flows (checkout, payment)
- Load testing for concurrent operations

# Monitor
pm2 monit
```

#### Option 2: Docker

Create `Dockerfile`:
```dockerfile
FROM node:16-alpine

WORKDIR /app

COPY package*.json ./
RUN npm ci --only=production

COPY . .

EXPOSE 3610

CMD ["node", "index.js"]
```

Create `docker-compose.yml`:
```yaml

  postgres:
    image: postgres:14
    environment:
      POSTGRES_DB: onmarket_db
      POSTGRES_USER: onmarket
      POSTGRES_PASSWORD: password
    volumes:
      - postgres-data:/var/lib/postgresql/data

  mongo:
    image: mongo:5
    volumes:
      - mongo-data:/data/db

  redis:
    image: redis:7-alpine
