Performance Benchmarking

Run performance benchmarks:

pytest tests/benchmarks/ --benchmark-only

Compare results:

pytest tests/benchmarks/ --benchmark-compare

Troubleshooting

Tests timing out

Increase timeout: pytest --timeout=600
Run fewer tests: pytest tests/integration/test_detection.py

Out of memory

Reduce test data size
Run tests sequentially: pytest -n 1

GPU tests failing

Tests requiring GPU are automatically skipped if no GPU available
Force skip: pytest -m "not requires_gpu"

Network tests failing

Check network connectivity
Skip network tests: pytest -m "not requires_network"
