Pytest

A solid reference for pytest patterns that covers the essentials without fluff. You get fixture scoping and teardown examples, mocking with patch and MagicMock, parametrize syntax for data-driven tests, and marker configurations. The conftest.py section is brief but shows the shared fixture pattern most projects need. The async test example is almost too minimal, just showing the decorator, but the commands section at the end is genuinely handy for things like running tests in parallel or filtering by marker. This is the kind of cheat sheet you want open when you're setting up a new test suite or can't remember the exact syntax for fixture scopes.
