Bump pytest from 8.3.4 to 9.0.0

[dependabot]

Bumps pytest from 8.3.4 to 9.0.0.

Release notes

Sourced from pytest's releases.

9.0.0

pytest 9.0.0 (2025-11-05)

New features

• #1367: Support for subtests has been added.

  subtests <subtests> are an alternative to parametrization, useful in situations where the parametrization values are not all known at collection time.

  Example:

  def contains_docstring(p: Path) -> bool:
      """Return True if the given Python file contains a top-level docstring."""
      ...
  def test_py_files_contain_docstring(subtests: pytest.Subtests) -> None:
  for path in Path.cwd().glob("*.py"):
  with subtests.test(path=str(path)):
  assert contains_docstring(path)

  Each assert failure or error is caught by the context manager and reported individually, giving a clear picture of all files that are missing a docstring.

  In addition, unittest.TestCase.subTest is now also supported.

  This feature was originally implemented as a separate plugin in pytest-subtests, but since then has been merged into the core.

  [!NOTE] This feature is experimental and will likely evolve in future releases. By that we mean that we might change how subtests are reported on failure, but the functionality and how to use it are stable.

• #13743: Added support for native TOML configuration files.

  While pytest, since version 6, supports configuration in pyproject.toml files under [tool.pytest.ini_options], it does so in an "INI compatibility mode", where all configuration values are treated as strings or list of strings. Now, pytest supports the native TOML data model.

  In pyproject.toml, the native TOML configuration is under the [tool.pytest] table.

  # pyproject.toml
  [tool.pytest]
  minversion = "9.0"
  addopts = ["-ra", "-q"]
  testpaths = [
      "tests",
      "integration",
  ]

... (truncated)

Pytest asyncio doesnt support 9.0 yet as far as I can tell.

	# We don't use nose style tests so disable them in pytest.
	# This stops pytest from running functions named `setup` in test files.

Should be migrated to rich config.

@dependabot please fix these issues and this should be good to go!

It won't be, there are changes that make the way we do mocks apparently non-functional on newer versions of pytest and pytest-xdist. We've seen similar issues on other projects (hence why a lot of the dependency bump PRs hold pytest & pytest extensions back).
