Release notes

Sourced from pytest-asyncio's releases.

pytest-asyncio v1.4.0

1.4.0 - 2026-05-26

Deprecated

• Overriding the event_loop_policy fixture is deprecated. Use the pytest_asyncio_loop_factories hook instead. (#1419)

Added

• Added the pytest_asyncio_loop_factories hook to parametrize asyncio tests with custom event loop factories.

  The hook returns a mapping of factory names to loop factories, and pytest.mark.asyncio(loop_factories=[...]) selects a subset of configured factories per test. When a single factory is configured, test names are unchanged.

  Synchronous @pytest_asyncio.fixture functions now see the correct event loop when custom loop factories are configured, even when test code disrupts the current event loop (e.g., via asyncio.run() or asyncio.set_event_loop(None)). (#1164)

Changed

• Improved the readability of the warning message that is displayed when asyncio_default_fixture_loop_scope is unset (#1298)
• Only import asyncio.AbstractEventLoopPolicy for type checking to avoid raising a DeprecationWarning. (#1394)
• Updated minimum supported pytest version to v8.4.0. (#1397)

Fixed

• Fixed a ResourceWarning: unclosed event loop warning that could occur when a synchronous test called asyncio.run() or otherwise unset the current event loop after pytest-asyncio had run an async test or fixture. (#724)

Notes for Downstream Packagers

• Added dependency on sphinx-tabs >= 3.5 to organize documentation examples into tabs. (#1395)
