Skip Parallel Testing for Now | Generated by AI
Summary: Sequential is the right choice here. Your 1860 tests run in ~8s already — parallel adds overhead without benefit at this scale. The Bad file descriptor errors in parallel mode suggest some tests do I/O that conflicts with process forking, but everything still passes. If you ever add slower tests (API calls, model loading), you can switch to -n auto since xdist is now in dev deps.
