# Performance Testing Suite
This directory contains performance tests for the Aniworld API and download system.
## Test Categories
### API Load Testing (`test_api_load.py`)
Tests API endpoints under concurrent load to ensure acceptable performance:
- **Load Testing**: Concurrent requests to endpoints
- **Sustained Load**: Long-running load scenarios
- **Concurrency Limits**: Maximum connection handling
- **Response Times**: Performance benchmarks
**Key Metrics:**
- Requests per second (RPS)
- Average response time
- Success rate under load
- Graceful degradation behavior
### Download Stress Testing (`test_download_stress.py`)
Tests the download queue and management system under stress:
- **Queue Operations**: Concurrent add/remove operations
- **Capacity Testing**: Queue behavior at limits
- **Memory Usage**: Memory leak detection
- **Concurrency**: Multiple simultaneous downloads
- **Error Handling**: Recovery from failures
**Key Metrics:**
- Queue operation success rate
- Concurrent download capacity
- Memory stability
- Error recovery time
## Running Performance Tests
### Run all performance tests:
```bash
conda run -n AniWorld python -m pytest tests/performance/ -v -m performance
```
### Run specific test file:
```bash
conda run -n AniWorld python -m pytest tests/performance/test_api_load.py -v
```
### Run with detailed output:
```bash
conda run -n AniWorld python -m pytest tests/performance/ -vv -s
```
### Run specific test class:
```bash
conda run -n AniWorld python -m pytest \
tests/performance/test_api_load.py::TestAPILoadTesting -v
```
## Performance Benchmarks
### Expected Results
**Health Endpoint:**
- RPS: ≥ 50 requests/second
- Avg Response Time: < 0.1s
- Success Rate: ≥ 95%
**Anime List Endpoint:**
- Avg Response Time: < 1.0s
- Success Rate: ≥ 90%
**Search Endpoint:**
- Avg Response Time: < 2.0s
- Success Rate: ≥ 85%
**Download Queue:**
- Concurrent Additions: Handle 100+ simultaneous adds
- Queue Capacity: Support 1000+ queued items
- Operation Success Rate: ≥ 90%
## Adding New Performance Tests
When adding new performance tests:
1. Mark tests with `@pytest.mark.performance` decorator
2. Use `@pytest.mark.asyncio` for async tests
3. Include clear performance expectations in assertions
4. Document expected metrics in docstrings
5. Use fixtures for setup/teardown
Example:
```python
@pytest.mark.performance
class TestMyFeature:
@pytest.mark.asyncio
async def test_under_load(self, client):
\"\"\"Test feature under load.\"\"\"
# Your test implementation
metrics = await measure_performance(...)
assert metrics["success_rate"] >= 95.0
```
## Continuous Performance Monitoring
These tests should be run:
- Before each release
- After significant changes to API or download system
- As part of CI/CD pipeline (if resources permit)
- Weekly as part of regression testing
## Troubleshooting
**Tests timeout:**
- Increase timeout in pytest.ini
- Check system resources (CPU, memory)
- Verify no other heavy processes running
**Low success rates:**
- Check application logs for errors
- Verify database connectivity
- Ensure sufficient system resources
- Check for rate limiting issues
**Inconsistent results:**
- Run tests multiple times
- Check for background processes
- Verify stable network connection
- Consider running on dedicated test hardware
## Performance Optimization Tips
Based on test results, consider:
1. **Caching**: Add caching for frequently accessed data
2. **Connection Pooling**: Optimize database connections
3. **Async Processing**: Use async/await for I/O operations
4. **Load Balancing**: Distribute load across multiple workers
5. **Rate Limiting**: Implement rate limiting to prevent overload
6. **Query Optimization**: Optimize database queries
7. **Resource Limits**: Set appropriate resource limits
## Integration with CI/CD
To include in CI/CD pipeline:
```yaml
# Example GitHub Actions workflow
- name: Run Performance Tests
run: |
conda run -n AniWorld python -m pytest \
tests/performance/ \
-v \
-m performance \
--tb=short
```
