[Random Crash] Usually during unittests

[DEKHTIARJonathan]

I'm having a weird crash - totally random and hard to reproduce:

tests/factories.py:68: in ProjectFactory
    country = random.choice(countries)[0]
/opt/hostedtoolcache/Python/3.13.1/x64/lib/python3.13/random.py:352: in choice
    return seq[self._randbelow(len(seq))]
/opt/hostedtoolcache/Python/3.13.1/x64/lib/python3.13/site-packages/django_countries/__init__.py:588: in __getitem__
    return next(itertools.islice(self.__iter__(), index, index + 1))
E   StopIteration

Probably means that self.__iter__() returns an empty result for some reasons.
I believe it may happen when something doesn't get initialized. No idea what and why.

Any idea what the issue could be ?

In case someone else has the issue, I haven't found the reason, but an additional "sleep" at the initialization addresses the issue:

• conftest.py:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import time

import pytest


# Note: This wait time is necessary because of django-countries sometimes being not
# ready. Simple workaround to fix the issue and barely noticeable.
def pytest_sessionstart(session):
    """Hook to delay the start of the pytest session."""
    initial_wait_time = 0.2  # seconds
    print(f"Waiting for {initial_wait_time} seconds before starting pytest session...")  # noqa: T201
    time.sleep(initial_wait_time)
