+# vLLM-omni Testing Scripts
+
+This directory contains automated testing scripts for vLLM-omni serving functionality.
+
+## Scripts Overview
+
+### 1. `test_serving.sh` - Comprehensive Test Suite
+Full-featured testing script that performs complete validation of the vLLM-omni serving functionality.
+
+**Features:**
+- Model existence validation
+- Environment setup verification
+- Import functionality testing
+- Server startup and health checks
+- Text generation testing
+- Performance benchmarking
+- API client integration testing
+- Comprehensive logging and error handling
+
+**Usage:**
+```bash
+# Use default model and port
+./scripts/test_serving.sh
+
+# Use specific model and port
+./scripts/test_serving.sh ./models/Qwen3-0.6B 8000
+
+# Use HuggingFace model
+./scripts/test_serving.sh Qwen/Qwen3-0.6B 8001
+
+# Show help
+./scripts/test_serving.sh --help
+```
+
+**Test Coverage:**
+- ✅ Model loading and server startup
+- ✅ Health and info endpoints
+- ✅ Text generation functionality
+- ✅ Performance metrics
+- ✅ API client integration
+- ✅ All imports working correctly
+
+### 2. `quick_test.sh` - Fast Validation
+Lightweight script for quick validation after making changes.
+
+**Features:**
+- Fast import testing
+- Basic server startup
+- Health endpoint validation
+- Simple text generation test
+- Retry mechanism for reliability
+
+**Usage:**
+```bash
+# Use default port (8000)
+./scripts/quick_test.sh
+
+# Use specific port
+./scripts/quick_test.sh 8001
+```
+
+**Test Coverage:**
+- ✅ Import functionality
+- ✅ Server startup
+- ✅ Health endpoint
+- ✅ Basic text generation
+
+## Prerequisites
+
+1. **Conda Environment**: Ensure `vllm_omni` environment is activated
+2. **Model Available**: Qwen3-0.6B model should be available in `./models/Qwen3-0.6B/`
+3. **Dependencies**: All vLLM-omni dependencies should be installed
+
+## Environment Setup
+
+```bash
+# Activate conda environment
+conda activate vllm_omni
+
+# Verify installation
+python -c "import vllm_omni; print('vLLM-omni ready')"
+```
+
+## Model Setup
+
+The scripts expect the Qwen3-0.6B model to be available. You can:
+
+1. **Use local model**: Place model in `./models/Qwen3-0.6B/`
+2. **Use HuggingFace model**: Pass `Qwen/Qwen3-0.6B` as model path
+3. **Download model**: Use the `download_models.py` script
+
+```bash
+# Download model using the provided script
+python scripts/download_models.py
+```
+
+## Output and Logging
+
+### Test Results
+- **Success**: Green `[SUCCESS]` messages
+- **Info**: Blue `[INFO]` messages  
+- **Warnings**: Yellow `[WARNING]` messages
+- **Errors**: Red `[ERROR]` messages
+
+### Log Files
+- `server.log`: Server startup and runtime logs
+- `api_client_test.log`: API client test results
+- `simple_usage_test.log`: Simple usage test results
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Server fails to start**
+   - Check if port is available
+   - Verify model path is correct
+   - Check conda environment is activated
+
+2. **Health check fails**
+   - Server may need more time to start
+   - Check server logs for errors
+   - Verify port is not blocked
+
+3. **Import errors**
+   - Ensure vllm_omni is properly installed
+   - Check conda environment activation
+   - Verify all dependencies are installed
+
+4. **Model not found**
+   - Verify model path exists
+   - Check model directory structure
+   - Use absolute paths if needed
+
+### Debug Mode
+
+For detailed debugging, run tests with verbose output:
+
+```bash
+# Enable debug mode
+export VLLM_OMNI_DEBUG=1
+./scripts/test_serving.sh
+```
+
+## Integration with CI/CD
+
+These scripts can be integrated into CI/CD pipelines:
+
+```yaml
+# Example GitHub Actions workflow
+- name: Test vLLM-omni
+  run: |
+    conda activate vllm_omni
+    ./scripts/test_serving.sh
+```
+
+## Performance Expectations
+
+### Quick Test
+- **Duration**: ~30-60 seconds
+- **Memory**: ~2-4GB RAM
+- **CPU**: Moderate usage during model loading
+
+### Comprehensive Test
+- **Duration**: ~2-5 minutes
+- **Memory**: ~2-4GB RAM
+- **CPU**: Moderate usage during model loading and generation
+
+## Contributing
+
+When adding new tests:
+
+1. **Update test_serving.sh** for comprehensive testing
+2. **Update quick_test.sh** for essential functionality
+3. **Update this README** with new test descriptions
+4. **Test both scripts** before committing changes
+
+## Support
+
+For issues with testing scripts:
+
+1. Check the troubleshooting section above
+2. Review log files for detailed error information
+3. Ensure all prerequisites are met
+4. Test with different ports if port conflicts occur
