8.4.2

pytest 8.4.2 (2025-09-03)

Bug fixes

• #13478: Fixed a crash when using console_output_style{.interpreted-text role="confval"} with times and a module is skipped.

• #13530: Fixed a crash when using pytest.approx{.interpreted-text role="func"} and decimal.Decimal{.interpreted-text role="class"} instances with the decimal.FloatOperation{.interpreted-text role="class"} trap set.

• #13549: No longer evaluate type annotations in Python 3.14 when inspecting function signatures.

  This prevents crashes during module collection when modules do not explicitly use from __future__ import annotations and import types for annotations within a if TYPE_CHECKING: block.

• #13559: Added missing [int]{.title-ref} and [float]{.title-ref} variants to the [Literal]{.title-ref} type annotation of the [type]{.title-ref} parameter in pytest.Parser.addini{.interpreted-text role="meth"}.

• #13563: pytest.approx{.interpreted-text role="func"} now only imports numpy if NumPy is already in sys.modules. This fixes unconditional import behavior introduced in [8.4.0]{.title-ref}.

Improved documentation

• #13577: Clarify that pytest_generate_tests is discovered in test modules/classes; other hooks must be in conftest.py or plugins.

Contributor-facing changes

• #13480: Self-testing: fixed a few test failures when run with -Wdefault or a similar override.
• #13547: Self-testing: corrected expected message for test_doctest_unexpected_exception in Python 3.14.
• #13684: Make pytest's own testsuite insensitive to the presence of the CI environment variable -- by ogrisel{.interpreted-text role="user"}.

v4.30.2 (2025-09-04)

Bugfixes - 4.30.2

- Previously, when tox ran in an automatically provisioned environment, it could hang waiting for a PEP 517 build backend
  if used in conjunction with the ``--installpkg`` option. This has been fixed by properly tearing down the automatically
  provisioned environment after the tests.
  - by :user:`vytas7` (:issue:`3600`)
v4.30.1 (2025-09-03)
Bugfixes - 4.30.1

• Prevent tox from hanging upon exit due to orphaned build threads and subprocesses when the --installpkg option is used with sdist.
  • by :user:vytas7 (:issue:3530)

v4.30.0 (2025-09-03)

Features - 4.30.0

- Add ``__TOX_ENVIRONMENT_VARIABLE_ORIGINAL_CI``, which passes through the ``CI`` variable if present. This is intended for use by other libraries to detect if tox is running under CI. (:issue:`3442`)
Bugfixes - 4.30.0

• Makes the error message more clear when pyproject.toml file cannot be loaded or is missing expected keys. (:issue:3578)

• The :func:tox_extend_envs() hook <tox.plugin.spec.tox_extend_envs> recently added in :pull:3591 turned out to not work well with tox run. It was fixed internally, not to exhaust the underlying iterator on the first use.

  -- by :user:webknjaz (:issue:3598)

v4.29.0 (2025-08-29)

Features - 4.29.0

- A new tox life cycle event is now exposed for use via :doc:`Plugins
  API </plugins>` -- by :user:`webknjaz`.
The corresponding hook point is :func:tox_extend_envs &lt;tox.plugin.spec.tox_extend_envs&gt;. It allows plugin authors to
declare ephemeral environments that they can then populate through
the in-memory configuration loader interface.
