Contributors Guide

Testing

Use poetry and pytest for testing.

$ poetry install
$ poetry run pytest

To get code coverage information:

$ poetry run pytest --cov=src --cov-report=html

This will generate an html coverage report in htmlcov/ directory.

There are a few tests that are slow running. These tests are not run by default, but can be included by setting the env variable RUN_SLOW_TESTS to any value.

$ RUN_SLOW_TEST=1 poetry run pytest

Running checks on commit

This project has pre-commit configured. Pre-commit will run configured checks at git commit time. To enable pre-commit on your local repository run:

$ poetry run pre-commit install

Versioning and Deploy

Before deploying a new version, please update the CHANGELOG.md file with a description of what is being changed.

Deploys to PyPi are done automatically on merges to master. In order to avoid overwriting a previous deploy, the version should be updated on all changes. The semver versioning scheme should be used for determining the version number.

The version is found in the pyproject.toml file.

Merging

Merges to master should be done by the evergreen commit queue. After a PR has been reviewed, add a comment with the text evergreen merge to merge the PR.
