Pytest Async Testing

Purpose

Async testing requires special handling of event loops, context managers, and async fixtures. This skill provides production-ready patterns for testing all async scenarios in modern Python.

# pyproject.toml
[tool.pytest.ini_options]
asyncio_mode = "auto"  # Auto-detect async tests
asyncio_default_fixture_loop_scope = "function"  # Max isolation per test

Then write async tests naturally:
