pytest -n 4 fails on the CI agent

QuizMediumPython only

pytest -n 4 works on your laptop. In CI it fails at once with "unrecognized arguments: -n" and exit code 4. Why?

  • -n comes from the pytest-xdist plugin, which is installed on your laptop but missing from requirements.txt
  • CI agents cannot run tests in parallel
  • -n must be written after the test path
  • Four tests failed
