build(deps-dev): bump pytest from 8.4.0 to 8.4.2

Bumps pytest from 8.4.0 to 8.4.2.

Release notes

Sourced from pytest's releases.

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"}.

8.4.1

pytest 8.4.1 (2025-06-17)

Bug fixes

• #13461: Corrected _pytest.terminal.TerminalReporter.isatty to support being called as a method. Before it was just a boolean which could break correct code when using -o log_cli=true).

• #13477: Reintroduced pytest.PytestReturnNotNoneWarning{.interpreted-text role="class"} which was removed by accident in pytest [8.4]{.title-ref}.

  This warning is raised when a test functions returns a value other than None, which is often a mistake made by beginners.

  See return-not-none{.interpreted-text role="ref"} for more information.

• #13497: Fixed compatibility with Twisted 25+.

Improved documentation

• #13492: Fixed outdated warning about faulthandler not working on Windows.
