# Validation (Python) This guide provides Python-specific validation commands for projects using Hatch environments. For shared validation expectations, see the [validation guide](validation.md). ## Commands Run validation commands with `hatch --env develop run `. **linters** Runs code quality checks including Ruff linting, Pyright type checking, and optional language-specific linting configured by the project. **pytest** Runs quick tests for rapid development feedback. **testers** Runs the full test suite with coverage reporting. Coverage artifacts are typically written under `.auxiliary/artifacts/coverage-pytest/`. **packagers** Builds distribution packages using Hatch. Projects with executable outputs may also run PyInstaller in this stage. **docsgen** Builds project documentation and link checks. Artifacts are typically written under `.auxiliary/artifacts/sphinx-html/`. **make-all** Runs the full quality sequence (linters, testers, packagers, docsgen). ## Workflow 1. **During Development**: Use `pytest` for quick feedback. 2. **Before Committing**: Run `linters` to catch quality and type issues. 3. **Before Pull Requests**: Run `make-all` for comprehensive validation. All required validation commands must pass before contributions can be accepted. If Git hooks are installed, they will run part of this workflow automatically.
