Testing

Tests require Pipenv and Bats. Run the tests with the following commands:

pipenv run lint  # Pre-commit hooks.
pipenv run doctest  # Doc tests.
pipenv run bats  # Bats tests.
pipenv run check  # Twine check.

Also, GitLab CI is setup for this project so every push to this repository is checked with all Python 2.7, Python 3.6 and later and all supported versions of PyPy.

Release

Release requires Pipenv. To bump the version run pipenv run bumpversion major|minor|patch to update the version and git commit and tag the changes, then run git push --follow-tags to push the git commit and tag. The GitLab CI will then build and upload a release to PyPI. To manually upload to PyPI run pipenv run build to build the Python package and pipenv run upload -s dist/* to upload a signed version.
