This skill provides focused guidance, code recipes, and a project initializer for pytest. It helps you:

• Add or refactor tests with clear structure and naming
• Use fixtures, parametrization, and marks effectively
• Mock dependencies (monkeypatch, pytest-mock) and isolate IO with tmp_path
• Test async code, CLIs, web apps (FastAPI, Flask, Django), and pandas/SQLAlchemy logic
• Configure coverage, flaky tests, xfail/skip, and CI integration

See SKILL.md for the skill definition, guides.md for quick how-tos, and recipes.md for copy‑paste patterns.
