[Python] Unit testing Python Firebase Cloud Functions in Flutter and VS Code - can't get the...

I have a Flutter project that has Firebase enabled with cloud_functions. It has created a functions directory in the root of the Flutter project.

Project Structure


my-app/
├─ lib/
├─ ios/
├─ functions/ (This is the cloud functions folder)
│ ├─ cloud_functions/
│ ├─ common/
│ │ ├─ models/
│ │ ├─ services/
│ │ ├─ ... other python files
│ ├─ tests/
│ │ ├─ ... pytest tests
│ ├─ main.py
│ ├─ requirements.txt
├─ ... other flutter folders



The cloud functions work fine in the Firebase Emulator with triggers working from Firestore events as expected. I have written some tests using Pytest which don't work. The issue I have is that can't import the modules.

In the cloud functions in a service for example I import a model with:

from cloud_functions.common.models.app_user import AppUser


This works fine in the emulator as the base directory is functions. However, my python interpreter in vsCode is set to the root directory of the whole project so to get the tests to import modules successfully I need to import as follows:

from functions.cloud_functions.common.models.app_user import AppUser


So basically I can either have the Firebase Emulator working or by changing all of the imports I can get the tests to run and pass.

Is there a way to force vsCode to use the functions directory as the root directory and have all modules defined from there? i.e. cloud_functions.common.models..... rather than functions.cloud_functions.common.models.....?
