Running individual test files doesn't work without conftest.py

When I try and run an individual test without a conftest.py file in the root directory of my project, it appears that it’s not loading modules correctly. Here’s a screenshot of what I’m doing.

The imports at the top of that test are:

import pytest
import datetime
import uuid
import kids.database as database

I would expect that pytest would have the same functionality without a conftest.py file as it would with an empty conftest.py file, but that appears not to be the case.

Note that the ModuleNotFoundError is probably the correct behavior here: The current directory isn’t necessarily in sys.path (where Python looks for modules) - it only happens to work because pytest adds it to load the conftest.py file.

IMHO, the proper solution is using a virtualenv where you have a development install of your project, and/or tox.

edit: @pfctdayelise was faster!

If you want this to throw an error, shouldn’t it also throw an error when conftest.py is found?

It should, which is why #2269 is open 😉
