Error documentation

1. ModuleNotFoundError when executing pytest

Error message

ModuleNotFoundError: No module named 'app'  

Action

pytest -vv  

Solution

Execute

python -m pytest

Explanation

• Running pytest with the python -m pytest command helps with this exact thing.
• Since your current package is not yet in your $PYTHONPATH or sys.path - pytest gets this error.
• By using python -m pytest you automatically add the working directory into sys.path for running pytest. Their documentation also mentions:

This is almost equivalent to invoking the command line script pytest
