ModuleNotFoundError when running tests from subfolders

Describe the bug Running unittest tests from project subfolders is very fragile. It’s common to receive the error "ModuleNotFoundError: No module named ‘[your test module]’ when executing.

The following seems to work:

• Test modules in the root of the project
• Test modules in a subfolder, with the same name as the subfolder

Everything else fails.

Steps to Reproduce

1. Unzip TestErrors.zip and try to execute tests.

Expected behavior Test methods are executed.

To my experience the problem still exist. __init__py -pp ----init.py ----person.py -test_pp ----__init__py ----test_person.py

from pp.person import Person throws Error:

ModuleNotFoundError: No module named 'pp'
