---

A pytest plugin that selectively runs tests impacted by codechanges via git introspection, ASL parsing, and dependency graph analysis.

• Configurable to meet your demands for both local and CI-driven invocations. :shipit:
• Built using a modern, best-of-breed Python stack, using astroid for Python code AST, NetworkX for dependency graph analysis, and GitPython for interacting with git repositories. :rocket:

Installation

You can install "pytest-impacted" via pipfrom PyPI:

$ pip install pytest-impacted

Usage

Use as a pytest plugin. Examples for invocation:

$ pytest --impacted --impacted-git-mode=unstaged --impacted-module=<my_root_module_name>

This will run all unit-tests impacted by changes to files which have unstaged modifications in the current active git repository.

$ pytest --impacted --impacted-git-mode=branch --impacted-base-branch=main --impacted-module=<my_root_module_name>

this will run all unit-tests impacted by changes to files which have been modified via any existing commits to the current active branch, as compared to the base branch passed in the --impacted-base-branch parameter.

Testing

Invoke unit-tests with:

uv run python -m pytest

Linting, formatting, static type checks etc. are all managed via pre-commit hooks. These will run automatically on every commit. You can invoke these manually on all files with:

pre-commit run --all-files
