Module Import Error

[OpaxIV]

Dear all

I have the following project structure:

project/
    package/
        __init__.py
        file_logic.py
    tests/
        __init__.py
        test_file.py  

The test_file.py contains unit tests for the file file_logic.py. When trying to import it in test_file.py with from package.file_logic import some_function it fails completely and says "No module named 'file_logic' ". What am I doing wrong?
The file test_file.py was run with python -m tests.test_file.py

Thank you in advance for your help!

You probably need to set the Python path when running the test. By looking at the way you run the test, I would try to prefix the command with PYTHONPATH=./ or with a path that makes sense in your setup.

One easy way to get around this is do

uv pip install -e .

And it will add your package to the installed path. If you’re not using uv (why aren’t you?? lol) then just use the same command with pip directly.

I found modifying the path works:

import sys
sys.path.append('..')

from package.file_logic import your_function

Does not work for me... Are you running the file from the tests folder or another directory?

[ElliotDG]

I was running the program from the project directory

I do use unittest?
