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"}.
