Updates pytest from 9.1.0 to 9.1.1

Release notes

Sourced from pytest's releases.

9.1.1

pytest 9.1.1 (2026-06-19)

Bug fixes

• #14220: Fixed a logic bug in pytest.RaisesGroup which would might cause it to display incorrect "It matches FooError() which was paired with BarError" messages.
• #14591: Fixed a regression in pytest 9.1.0 which caused overriding a parametrized fixture with an indirect @​pytest.mark.parametrize to fail with "duplicate parametrization of '<fixture name>'".
• #14606: Fixed list-item typing errors from mypy in @pytest.mark.parametrize <pytest.mark.parametrize ref> argvalues parameter.
• #14608: Fixed a regression in pytest 9.1.0 where conftest.py files located in <invocation dir>/test* were no longer loaded as initial conftests when invoked without arguments. This could cause certain hooks (like pytest_addoption) in these files to not fire.

Updates anyio from 4.13.0 to 4.14.0

Release notes

Sourced from anyio's releases.

4.14.0

• Added support for Python 3.15

• Added an asynchronous implementation of the itertools module (#998; PR by @​11kkw)

• Added the local_port parameter to connect_tcp() to allow binding to a specific local port before connecting (#1067; PR by @​nullwiz)

• Added support for custom capacity limiters in async path and file I/O functions and classes

• Added the create_task() task group method for easier asyncio migration (returns a TaskHandle) (#1098)

• Changed TaskGroup.start_soon() to return a TaskHandle

• Added an option for TaskGroup.start() to return a TaskHandle (which then contains the start value in the start_value property)

• Added the cancel() convenience method to TaskGroup as a shortcut for cancelling the task group's cancel scope

• Improved the error message when a known backend is not installed to suggest the install command (#1115; PR by @​EmmanuelNiyonshuti)

• Improved anyio.Path to preserve subclass types by returning Self in methods that return path objects (#1130; PR by @​EmmanuelNiyonshuti)

• Changed the parameter type annotation in anyio.Path.write_bytes() to accept any ReadableBuffer, thus allowing it to accept bytearray and memoryview to match pathlib.Path.write_bytes() (#1135; PR by @​SAY-5)

• Changed several type annotations to only accept callables returning coroutine-like objects instead of arbitrary awaitables:

  • TaskGroup.start_soon()
  • TaskGroup.start()
  • anyio.from_thread.run()

  This reverts an earlier change from v3.7.0 which was made in error. (#1153)

• Changed anyio.run to support callables returning arbitrary awaitables at runtime on all backends. Previously, this only worked on asyncio (#1171; PR by @​gschaffner)

• Changed several classes (and their subclasses) to have __slots__ (with __weakref__):

  • anyio.CancelScope
  • anyio.CapacityLimiter
  • anyio.Condition
  • anyio.Event
  • anyio.Lock
  • anyio.ResourceGuard
  • anyio.Semaphore

• Fixed cancellation exception escaping a cancel scope when triggered via check_cancelled() in a worker thread (#1113)

• Fixed TaskGroup raising AttributeError instead of a clear error when entered more than once (#1109; PR by @​bahtya)

• Fixed lost type information when passing arguments to lru_cache (#1104; PR by @​Graeme22)

• Fixed test resumption after KeyboardInterrupt in async generator fixtures on the asyncio backend (#1060; PR by @​EmmanuelNiyonshuti)
