How to make my Python unit tests to import the tested modules if they are in sister folders?

Question

I am still getting my head around the import statement. If I have 2 folders in the same level:

1. src
2. test

How to make the py files in test import the modules in src? Is there a better solution (like put a folder inside another?)

The code you want is for using src/module_name.py

from src import module_name

Your directory structure is what I use but with the model name instead from src. I got this structure from J Calderone's blog and

Answer 2

Try this out:

import sys
import os
sys.path.append(os.path.join('..', 'src'))
import module_in_src_folder
