Description

Tests often fail with no apparent cause. For example, in the following case, tests were passing on the pull request but they failed on merge to main: https://github.com/MIT-LCP/wfdb-python/actions/runs/9784161262/attempts/1

After re-running the failed tests, they passed without error: https://github.com/MIT-LCP/wfdb-python/actions/runs/9784161262. The original error is shown below:

Piste de recherche

Commencez par tests/test_record.py au niveau de test_dl_database_with_dat_file, puis examinez la configuration de pytest dans pyproject.toml et l’exécution GitHub Actions liée. Reproduisez l’échec sous Windows et déterminez si l’échec intermittent est lié à Multiprocessing ou aux téléchargements réseau ; le travail est terminé lorsque le test CI s’exécute de manière fiable sans le plantage signalé.
