Dependencies

Python: 3.6.9
Distributor ID: Peppermint
Description: Peppermint 10 Ten
Release: 10
Codename: bionic

Start by reproducing the setup with Python 3.6.9 using requirements.txt, test_requirements.txt, and setup.py develop, then run pytest tests/. Read tests/test_probe_expiry_alert.py, especially its dataclasses import, and inspect the dependency files to determine how the test suite should support the documented environment. Done means pytest tests/ completes collection without the reported ModuleNotFoundError.
