How to bypass __init__.py when unittest a module in a package by using pytest?

I have a file structure similar to the following:

app/
 |--- __init__.py
 |--- module_under_test.py
test/
 |--- test_module.py

I want to unittest a module in a package by using pytest. When I import the module in my test file, the code in the __init__.py gets executed. However I want to bypass the code in the __init__.py file because in __init__.py other external dependencies are used. One way I can think of is mocking all necessary objects in __init__.py by using patch.

What is the best practise to solve this problem? Thank you.

If you really need to avoid invoking __init__.py file, there is a rather dirty workaround. For the given directory structure:

app/
 |--- __init__.py
 |--- module_under_test.py
test/
 |--- test_module.py

Add at the top of the test_module.py

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

from module_under_test import some_function
