How do you test this?

[myarcana]

Both python tests/test_simple.py and python -m unittest discover throw errors because of the import

  File "sampleproject/tests/test_simple.py", line 7, in <module>
    from sample.simple import add_one
ModuleNotFoundError: No module named 'sample'

So what's the correct way to test this package and other packages while in development?

[dmtucker]

This project has a tox.ini file to automate running the tests: https://tox.wiki/en/latest/index.html

tox

To run manually, you must install the project before it can be tested:

python3 -m venv myvenv
myvenv/bin/python -m pip install .
myvenv/bin/python -m unittest discover

I have installed tox, but that gave a lot of errors:
