Python importing a module from a parallel directory

by

Python adds the folder containing the script you launch to the PYTHONPATH, so if you run

python test/tests.py

Only the folder test is added to the path (not the base dir that you’re executing the command in).

Instead run your tests like so:

python -m test.tests

This will add the base dir to the python path, and then classes will be accessible via a non-relative import:

from src.classes import etc

If you really want to use the relative import style, then your 3 dirs need to be added to a package directory

package
* __init__.py
* project
* src
* test

And you execute it from above the package dir with

python -m package.test.tests
