The Python Testing Toolkit: 4 Drop-In Files for Production pytest

Every Python project eventually needs the same test infrastructure. You write conftest.py from scratch, reach for the same Hypothesis patterns, copy async fixture code from a Stack Overflow answer that's three major versions out of date. I've done this enough times that I started keeping the files. This week I packaged them up. The Python Testing Toolkit is available now on Gumroad: four production-ready Python files — conftest_production.py , hypothesis_strategies.py , async_test_patterns.py , and parametrize_factories.py . $49, one-time download, MIT license. Here's exactly what's in each one. conftest_production.py — the conftest you'd write if you had eight hours Most conftest.py tutorials show you database fixtures or HTTP mocking. Almost none show both in a form that composes cleanly with async tests, FastAPI dependency overrides, and environment variable isolation. This file handles all of it: # Transaction rollback per test — no cleanup needed def test_creates_user ( db_session
