We welcome contributions in the form of pull requests.
If proposing changes to package source code, please run the test suite in python2 and python3 by running pytest or python setup.py test from within the repository root.
If using pytest directly, we suggest first activating the appropriate Python version's virtual environment and running pip install --ugprade ./.
Otherwise, simply specify the appropriate Python version, i.e. python2 setup.py test or python3 setup.py test.
