 Possible options for testing:
-* For more verbosity, add "-v" or even "-vv" like this: pytest -vv
-* To run just unit tests: pytest -munit
-* To run just integration tests: pytest -mint
-* To run a smoke test with only one device connected serially: pytest -msmoke1
-  CAUTION: Running smoke1 will reset values on the device.
-           Be sure to hit the button on the device to reset after the test is run.
-* To run a specific test: pytest -msmoke1 meshtastic/test/test_smoke1.py::test_smoke1_info
-* To add another classification of tests, then look in pytest.ini
-* To see the unit test code coverage: pytest --cov=meshtastic
