# Testing Guide for verify_sonarr_api Function

This guide explains how to test the `verify_sonarr_api` function from the plexsonarr.py script.

## Test Files Overview

### 1. test_verify_api.py - Simple Interactive Test
A user-friendly test script that provides:
- ✅ Mocked success tests
- ❌ Mocked failure tests  
- 🧪 HTTP error simulation
- 🌐 Real API testing (optional)

**Usage:**
```bash
python test_verify_api.py
```

### 2. test_plexsonarr.py - Comprehensive pytest Suite
Full test suite using pytest framework that covers:
- Successful API verification
- HTTP errors (401, 404, 500)
- Connection errors
- Timeout scenarios
- Invalid JSON responses

**Usage:**
```bash
pytest test_plexsonarr.py -v
```

## Quick Start

### Install Dependencies
```bash
pip install -r requirements.txt
```

### Run Simple Tests
```bash
python test_verify_api.py
```

### Run Comprehensive Tests
```bash
pytest test_plexsonarr.py -v
```

### Run All Tests
```bash
pytest -v
```

## Test Scenarios Covered

### ✅ Success Cases
- Valid API response (200 OK)
- Correct API key and URL
- Successful connection to Sonarr

### ❌ Error Cases
- **401 Unauthorized**: Invalid API key
- **404 Not Found**: Incorrect endpoint or server
- **500 Server Error**: Sonarr internal error
- **Connection Error**: Network issues
- **Timeout**: Slow response from server

### 🔧 Edge Cases
- Invalid JSON response
- Malformed responses
- Network connectivity issues

## Configuration

The tests use the same configuration as your main script:
```python
SONARR_API_KEY = "2537de37fded4874ae83da9cf3c14f34"
SONARR_SERVER_URL = "http://192.168.50.111:8989"
```

## Understanding Test Output

### Successful Test Run
```
🚀 Starting verify_sonarr_api tests...
✅ Mock success test passed!
✅ Mock failure test passed!
✅ Mock HTTP error test passed!
✅ Real API test passed! Your Sonarr API is working.
```

### Failed Real API Test
```
❌ Failed to verify Sonarr API: HTTPSConnectionPool(host='192.168.50.111', port=8989)
💡 Tip: Check your SONARR_SERVER_URL and SONARR_API_KEY configuration
```

## Pytest Output Explanation

```bash
pytest test_plexsonarr.py -v
```

Each test case shows:
- **PASSED**: Test completed successfully
- **FAILED**: Test found an issue
- **Coverage**: Which scenarios were tested

## Troubleshooting

### Common Issues

1. **Import Errors**
   ```
   ModuleNotFoundError: No module named 'pytest'
   ```
   **Solution**: Install dependencies with `pip install -r requirements.txt`

2. **Connection Refused**
   ```
   ConnectionError: ('Connection aborted.', RemoteDisconnected('Remote end closed connection without response'))
   ```
   **Solution**: Check if Sonarr is running and accessible

3. **API Key Invalid**
   ```
   401 Unauthorized
   ```
   **Solution**: Verify your SONARR_API_KEY in the configuration

### Debugging Tips

1. **Check Sonarr Status**
   ```bash
   curl http://192.168.50.111:8989/api/v3/system/status?apikey=YOUR_API_KEY
   ```

2. **Test Network Connectivity**
   ```bash
   ping 192.168.50.111
   telnet 192.168.50.111 8989
   ```

3. **Verify API Key**
   - Open Sonarr web interface
   - Go to Settings → General
   - Check the API Key in Security section

## Test Development

### Adding New Tests

To add a new test case to `test_plexsonarr.py`:

```python
def test_verify_sonarr_api_new_scenario(self):
    """Test description"""
    with requests_mock.Mocker() as m:
        expected_url = f"{plexsonarr.SONARR_SERVER_URL}/api/v3/system/status?apikey={plexsonarr.SONARR_API_KEY}"
        m.get(expected_url, status_code=YOUR_STATUS_CODE)
        
        # Your test logic here
        with pytest.raises(ExpectedException):
            plexsonarr.verify_sonarr_api()
```

### Test Best Practices

1. **Mock External Calls**: Always mock HTTP requests in unit tests
2. **Test Edge Cases**: Include error scenarios and unusual responses
3. **Clear Test Names**: Use descriptive test function names
4. **Isolated Tests**: Each test should be independent
5. **Verify Behavior**: Check both success and failure paths

## Continuous Integration

Add to your CI pipeline:

```yaml
# .github/workflows/test.yml
name: Tests
on: [push, pull_request]
jobs:
  test:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: Set up Python
      uses: actions/setup-python@v2
      with:
        python-version: 3.11
    - name: Install dependencies
      run: pip install -r requirements.txt
    - name: Run tests
      run: pytest test_plexsonarr.py -v
```

## Performance Testing

For load testing the API:

```bash
# Install httpie for testing
pip install httpie

# Test API endpoint directly
http GET "http://192.168.50.111:8989/api/v3/system/status?apikey=YOUR_API_KEY"
```

## Summary

The testing setup provides:
- 🔍 **Comprehensive Coverage**: All success/failure scenarios
- 🚀 **Easy Execution**: Simple commands to run tests
- 📊 **Clear Reporting**: Detailed output and error messages
- 🛠️ **Development Ready**: Easy to extend with new test cases
- 🌐 **Real-world Testing**: Option to test against actual Sonarr API

This ensures your `verify_sonarr_api` function works correctly in all scenarios!
