Feel free to clone the project on GitHub.
Once you made a change, try to add a test for your feature/fix. At least assume that you have'nt broke anything by running tox:
$ tox
...
py34: commands succeeded
py35: commands succeeded
flake8: commands succeeded
docs: commands succeeded
congratulations :)
You can run tests for a specific version:
$ tox -e py35
Running individual test:
$ tox -e py35 tests/test_manager.py::test_connection
You can also build the docs with:
$ tox -e docs
And check the result:
$ firefox .tox/docs/tmp/html/index.html
