Pull request overview
This PR experiments with modernizing pytest’s build/dev infrastructure by adopting uv lockfiles and PEP 735 dependency groups, and integrating tox-uv into CI to speed up environment creation and installs.
Changes:
- Add a
uv.locklockfile and define adevdependency group inpyproject.toml. - Switch tox environments to use
dependency_groups(and addtox-uv) instead of thedevextra. - Update GitHub Actions workflows to install
tox-uvalongsidetox.

LGTM but I don't know much about uv/pyproject.toml

This is an experimental change to modernize the build infrastructure: - Add uv.lock for reproducible dependency resolution - Migrate from optional-dependencies to dependency-groups (PEP 735) - Configure tox to use tox-uv for faster dependency installation - Update all GitHub Actions workflows to install tox-uv - Update minimum version pins to sensible modern values: - iniconfig>=2, packaging>=24, pygments>=2.15, tomli>=2 - attrs>=23.1, hypothesis>=6.75, numpy>=1.26, pytest-xdist>=3.5 - coverage>=7.5, pexpect>=4.9, pre-commit>=4 - Remove py library from dev deps (pytest vendors its own minimal version) Usage: uv sync --group dev # Install with dev dependencies uv run pytest # Run tests uvx --with tox-uv tox # Run tox with uv backend Co-authored-by: Cursor AI <ai@cursor.sh> Co-authored-by: Anthropic Claude <claude@anthropic.com>
The PEP 735 dependency group is a superset of the old optional extra and nothing in the repo references pytest[dev] anymore. Co-authored-by: Cursor AI <ai@cursor.sh> Co-authored-by: Anthropic Claude Opus 4 <claude@anthropic.com>
Keep optional-dependencies.dev so CONTRIBUTING's pip install -e ".[dev]" still works, and allowlist uv for the plugins tox env. Co-authored-by: Cursor AI <ai@cursor.sh> Co-authored-by: Cursor Grok 4.5 <grok@x.ai>
The warning is attributed to stdlib pty (stacklevel=1), not ptyprocess, and only fails under filterwarnings=error on Python 3.15+ (especially macOS, where Mach counts extra runtime threads). Co-authored-by: Cursor AI <ai@cursor.sh> Co-authored-by: Cursor Grok 4.5 <grok@x.ai>
Python 3.15 defaults pdb to PyREPL, which adds ANSI/bracketed-paste sequences that break exact pexpect matching on macOS. Co-authored-by: Cursor AI <ai@cursor.sh> Co-authored-by: Cursor Grok 4.5 <grok@x.ai>
Keep PYTHON_BASIC_REPL for pdb selftests and restore the strict assert. Make optional-dependencies.dev an empty stub scheduled for removal, document dependency-group installs, and rely on the pyproject.toml forkpty warning filter only. Co-authored-by: Cursor AI <ai@cursor.sh> Co-authored-by: Cursor Grok 4.5 <grok@x.ai>
Keep the published `dev` extra for external repos that still use it, have `[dependency-groups].dev` pull from that extra, and document only the group-based install path for contributing. Co-authored-by: Cursor AI <ai@cursor.sh> Co-authored-by: Cursor Grok 4.5 <grok@x.ai>
