python: import class from a different subfolder in the parent folder (tests)

I moved my tests to a separate subfolder in the project, and now testing my classes does not work anymore.

|--  project
|   |main.py
|   |-- lib
|   |   |__init__.py
|   |   |myclass.py
|   |-- tests
|   |   |__init__.py
|   |   |test_myclass.py

Both init files are empty.

but when I run the test (i'm in the tests folder and typing python -m unittest) I get the following error:

ModuleNotFoundError: No module named 'lib'

at the line from lib.myclass import Myclass

I also saw that one could use sys and os to add the parent folder to the path, but each time that I do it, the code that adds it is automatically going under all the imports in vscode (I guess due to some automatic formatting?) and therefore is not ran on time.

That's because once you are in tests folder your working directory dir is:

.\
.\test_mycalss.py

You should run tests from project so your working directory will cover whole tree:

.\
.\main.py
.\lib\
and so on

Your project cannot view lib.myclass because in folder tests there is no folder lib.
