  • Every pull request
  • Nightly at 2 AM UTC
  • Manual trigger with [stress-test] in commit message

See .github/workflows/integration-tests.yml for configuration.

CI Pipeline Stages

  1. Integration Tests: Core functionality validation
  2. Benchmark Tests: Performance regression detection
  3. Stress Tests: Maximum load validation (nightly)

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"

Contributing

When adding new tests:

  1. Follow existing test structure
  2. Add appropriate markers (@pytest.mark.integration, etc.)
  3. Update this README with new test categories
  4. Ensure tests are deterministic (use fixtures/seeds)
