Contributing Guide

All contributions are greatly appreciated! Before contributing, please read the code of conduct.

Development Setup

This project uses Poetry to manage dependencies and builds, and you will need to install it before working on Decoy.

Once Poetry is installed, you should be good to set up a virtual environment and install development dependencies. Python 3.11 is recommended for development.

git clone https://github.com/mcous/decoy.git
cd decoy
poetry install

Development Tasks

Decoy uses poethepoet to manage development tasks. If you want to quickly check everything, run the following:

poetry run poe all

Tests

Decoy's tests are run using pytest. To run tests in watch mode:

poetry run poe test

To run tests once and report coverage

poetry run poe test-once
poetry run poe coverage

In an exciting twist, since version 1.6.0, Decoy's tests rely on Decoy itself to test (and more importantly, design) the relationships between Decoy's internal APIs. This means:

  • Decoy's unit test suite serves as an end-to-end test of Decoy by virtue of existing (wow, very meta, actually kind of cool).
  • Changes that break a small part of Decoy may result in a large number of test failures, because if Decoy breaks it can't be used to test itself.

If you find yourself in a situation where Decoy's test suite has blown up, concentrate on getting the test suites that don't use Decoy to pass. From there, lean on the type-checker to guide you to any components that aren't properly hooked up. Decoy also has a end-to-end smoke test suite (tests/test_decoy.py) that can be helpful in getting things back to green.

Checks

Decoy's source code is typechecked with mypy and linted/formatted with ruff.

poetry run poe check
poetry run poe lint
poetry run poe format

Documentation

Decoy's documentation is built with mkdocs, which you can use to preview the documentation site locally.

poetry run docs

Deploying

The library and documentation will be deployed to PyPI and GitHub Pages, respectively, by CI. To trigger the deploy, cut a new version and push it to GitHub.

Decoy adheres to semantic versioning, so care should be taken to bump accurately.

# checkout the main branch and pull down latest changes
git checkout main
git pull

# bump the version
# replace ${bump_version} with a bump specifier, like "minor"
poetry version ${bump_version}

# add the bumped pyproject.toml
git add pyproject.toml

# commit and tag the bump
# replace ${release_version} with the actual version string
git commit -m "chore(release): ${release_version}"
git tag -a v${release_version} -m "chore(release): ${release_version}"
git push --follow-tags
