It supports asyncio, trio, and curio as async backends, automatically parametrizing tests across all installed backends by default. The plugin handles contextvars correctly for both async and sync fixtures, and includes a helper fixture (aiosleep) that abstracts over the sleep function of whichever backend is currently running.\n\nYou install it alongside pytest and write async test functions as you normally would; the plugin intercepts them at collection time and runs them through the appropriate event loop. You can customize which backends run globally via a fixture override, or mark individual tests to run on specific backends. It's designed for straightforward async testing without boilerplate.","worth_installing":"Yes. It is a lightweight, permissively licensed plugin with no security vulnerabilities, low install friction, and straightforward async test support. The aging maintenance status is not a blocker\u2014the codebase is stable and the repo remains active. Install it if you need to test async Python code with pytest and want to avoid boilerplate or test across multiple async backends."},"id":"pytest-aio","links":{"html":"https://skillfed.io/packages/pytest-aio","md":"https://skillfed.io/packages/pytest-aio.md","pypi":"https://pypi.org/project/pytest-aio/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2026-02-12","license_spdx":"MIT","license_treatment":"permissive","name":"pytest-aio","python_support":"supports_current","summary":"Pytest plugin for testing async python code"},"popularity":{"monthly_downloads":77898,"position":14483,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.1.7"}
