8.3.5

pytest 8.3.5 (2025-03-02)

Bug fixes

• #11777: Fixed issue where sequences were still being shortened even with -vv verbosity.
• #12888: Fixed broken input when using Python 3.13+ and a libedit build of Python, such as on macOS or with uv-managed Python binaries from the python-build-standalone project. This could manifest e.g. by a broken prompt when using Pdb, or seeing empty inputs with manual usage of input() and suspended capturing.
• #13026: Fixed AttributeError{.interpreted-text role="class"} crash when using --import-mode=importlib when top-level directory same name as another module of the standard library.
• #13053: Fixed a regression in pytest 8.3.4 where, when using --import-mode=importlib, a directory containing py file with the same name would cause an ImportError
• #13083: Fixed issue where pytest could crash if one of the collected directories got removed during collection.

Improved documentation

• #12842: Added dedicated page about using types with pytest.

  See types{.interpreted-text role="ref"} for detailed usage.

Contributor-facing changes

• #13112: Fixed selftest failures in test_terminal.py with Pygments >= 2.19.0
• #13256: Support for Towncrier versions released in 2024 has been re-enabled when building Sphinx docs -- by webknjaz{.interpreted-text role="user"}.

Mypy Release Notes

Next Release

Different Property Getter and Setter Types

Mypy now supports using different types for property getter and setter.

class A:
    value: int
@property
def f(self) -> int:
    return self.value
@f.setter
def f(self, x: str | int) -> None:
    try:
        self.value = int(x)
    except ValueError:
        raise Exception(f"'{x}' is not a valid value for 'f'")

Contributed by Ivan Levkivskyi (PR 18510)

Selectively Disable Deprecated Warnings

It's now possible to selectively disable warnings generated from warnings.deprecated using the --deprecated-calls-exclude option.

# mypy --enable-error-code deprecated
#      --deprecated-calls-exclude=foo.A
import foo
foo.A().func()  # OK, the deprecated warning is ignored
file foo.py
from typing_extensions import deprecated
class A:
@​deprecated("Use A.func2 instead")
def func(self): pass
