v1.1.0: pytest-asyncio 1.1.0

Compare Source

Added

• Propagation of ContextVars from async fixtures to other fixtures and tests on Python 3.10 and older (#​127)
• Cancellation of tasks when the loop_scope ends (#​200)
• Warning when the current event loop is closed by a test

Fixed

• Error about missing loop when calling functions requiring a loop in the finally clause of a task (#​878)
• An error that could cause duplicate warnings to be issued

Notes for Downstream Packagers

• Added runtime dependency on backports.asyncio.runner for use with Python 3.10 and older

v1.0.0: pytest-asyncio 1.0.0

Compare Source

1.0.0 - 2025-05-26

Removed

• The deprecated event_loop fixture.
  (#​1106)

Added

• Prelimiary support for Python 3.14
  (#​1025)

Changed

• Scoped event loops (e.g. module-scoped loops) are created once rather
  than per scope (e.g. per module). This reduces the number of fixtures
  and speeds up collection time, especially for large test suites.
  (#​1107)
• The loop_scope argument to pytest.mark.asyncio no longer forces
  that a pytest Collector exists at the level of the specified scope.
  For example, a test function marked with
  pytest.mark.asyncio(loop_scope="class") no longer requires a class
  surrounding the test. This is consistent with the behavior of the
  scope argument to pytest_asyncio.fixture.
  (#​1112)

Fixed

• An error caused when using pytest's [--setup-plan]{.title-ref}
  option.
  (#​630)
• Unsuppressed import errors with pytest option
  --doctest-ignore-import-errors
  (#​797)
• A "fixture not found" error in connection with package-scoped loops
  (#​1052)

Notes for Downstream Packagers

• Removed a test that had an ordering dependency on other tests.
  (#​1114)

v0.26.0: pytest-asyncio 0.26.0

Compare Source

• Adds configuration option that sets default event loop scope for all tests #​793
• Improved type annotations for pytest_asyncio.fixture #​1045
• Added typing-extensions as additional dependency for Python <3.10 #​1045

v0.25.3: pytest-asyncio 0.25.3

Compare Source

• Avoid errors in cleanup of async generators when event loop is already closed #​1040

v0.25.2: pytest-asyncio 0.25.2

Compare Source

• Call loop.shutdown_asyncgens() before closing the event loop to ensure async generators are closed in the same manner as asyncio.run does #​1034

v0.25.1: pytest-asyncio 0.25.1

Compare Source

• Fixes an issue that caused a broken event loop when a function-scoped test was executed in between two tests with wider loop scope #​950
• Improves test collection speed in auto mode #​1020
• Corrects the warning that is emitted upon redefining the event_loop fixture

v0.25.0: pytest-asyncio 0.25.0

Compare Source

0.25.0 (2024-12-13)

• Deprecated: Added warning when asyncio test requests async @pytest.fixture in strict mode. This will become an error in a future version of flake8-asyncio. #​979
• Updates the error message about pytest.mark.asyncio's scope keyword argument to say loop_scope instead. #​1004
• Verbose log displays correct parameter name: asyncio_default_fixture_loop_scope #​990
• Propagates contextvars set in async fixtures to other fixtures and tests on Python 3.11 and above. #​1008

v0.24.0: pytest-asyncio 0.24.0

Compare Source

0.24.0 (2024-08-22)

• BREAKING: Updated minimum supported pytest version to v8.2.0
• Adds an optional loop_scope keyword argument to pytest.mark.asyncio. This argument controls which event loop is used to run the marked async test. #​706, #​871
• Deprecates the optional scope keyword argument to pytest.mark.asyncio for API consistency with pytest_asyncio.fixture. Users are encouraged to use the loop_scope keyword argument, which does exactly the same.
• Raises an error when passing scope or loop_scope as a positional argument to @pytest.mark.asyncio. #​812
• Fixes a bug that caused module-scoped async fixtures to fail when reused in other modules #​862 #​668
