Running Unit Tests
==================

Unit tests are located in the ``tests`` directory.

To test both the pure Python and C extension module based implementations,
run the command:

::

    tox

By default tests are run for Python 2.6, 2.7, 3.3, 3.4 and PyPy, with and
without the C extensions.

::

    py26-without-extensions
    py27-without-extensions
    py33-without-extensions
    py34-without-extensions

    py26-with-extensions
    py27-with-extensions
    py33-with-extensions
    py34-with-extensions

    pypy-without-extensions

If wishing to run tests for a specific Python combination you can run
``tox`` with the ``-e`` option.

::

    tox -e py33-with-extensions

If adding more tests and you need to add a test which is Python 2 or
Python 3 specific, then end the name of the Python code file as
``_py2.py`` or ``_py3.py`` appropriately.

For further options refer to the documentation for ``tox``.

Coverage
--------

Coverage is collected and sent to `Coveralls <https://coveralls.io>`_ when
running the tests automatically in `Travis CI <https://travis-ci.org>`_.
To collect and view coverage results locally, here's the sequence of
commands:

::

    export COVERAGE_CMD="coverage run -m"
    export COVERAGE_DEP=coverage
    tox
    coverage combine
    coverage html --ignore-errors

At this point there's a directly called ``htmlcov`` with the formatted
results.

Add documentation for running coverage locally.
