+Testing
+=======
+PySAML2 uses the `pytest <http://doc.pytest.org/en/latest/>`_ framework for
+testing. To run the tests on your system's version of python 
+
+1. Create and activate a `virtualenv <https://virtualenv.pypa.io/en/stable/>`_.
+2. Inside the virtualenv, install the dependencies needed for testing :code:`pip install -r tests/test_requirements.txt`
+3. Run the tests :code:`py.test tests`
+
+To run tests in multiple python environments, you can use
+`pyenv <https://github.com/yyuu/pyenv>`_ with `tox <https://tox.readthedocs.io/en/latest/>`_.
