Test Pytest Config

conftest.py                    # Root: Django settings, shared fixtures
apps/firmwares/tests/
    conftest.py                # App-level: app-specific factories, fixtures
    test_models.py
    test_views.py

Root conftest.py Pattern

import pytest
from django.test import RequestFactory

@pytest.fixture
def request_factory():
    return RequestFactory()

@pytest.fixture
def staff_user(db):
    from apps.users.models import User
    return User.objects.create_user(
        username="staff", email="[email protected]",
        password="testpass123", is_staff=True,
    )

Run Commands

# All tests with coverage
& .\.venv\Scripts\python.exe -m pytest --cov=apps --cov-report=term-missing
# Single app
& .\.venv\Scripts\python.exe -m pytest apps/firmwares/tests/ -v
# By keyword
& .\.venv\Scripts\python.exe -m pytest -k "test_download"
# Exclude slow
& .\.venv\Scripts\python.exe -m pytest -m "not slow"

Red Flags

• Missing DJANGO_SETTINGS_MODULE in pyproject.toml — tests use wrong settings
• Fixtures that create data without db or django_db marker — DatabaseError
• conftest.py importing from app models at module level — import loops
• Not using --strict-markers — typos in marker names silently pass
