pytest-asyncio 1.2.0

1.2.0 - 2025-09-12

Added

• --asyncio-debug CLI option and asyncio_debug configuration option to enable asyncio debug mode for the default event loop. (#980)
• A pytest.UsageError for invalid configuration values of asyncio_default_fixture_loop_scope and asyncio_default_test_loop_scope. (#1189)
• Compatibility with the Pyright type checker (#731)

Fixed

• RuntimeError: There is no current event loop in thread 'MainThread' when any test unsets the event loop (such as when using asyncio.run and asyncio.Runner). (#1177)
• Deprecation warning when decorating an asynchronous fixture with @pytest.fixture in [strict]{.title-ref} mode. The warning message now refers to the correct package. (#1198)

Notes for Downstream Packagers

• Bump the minimum required version of tox to v4.28. This change is only relevant if you use the tox.ini file provided by pytest-asyncio to run tests.
• Extend dependency on typing-extensions>=4.12 from Python<3.10 to Python<3.13.
