Testing
--------

For a fast test run using current environment, use pytest_::

    $ pytest tests

For more thorough testing, Tox_ configuration will run tests on python
versions 2.7 and 3.4 -- 3.7::

    $ tox

Additionally, test can be run with no local requirements other than the
ubiquitous docker::

    $ docker-compose up pgcopy
