+Testing
+=============================
+
+To make sure everything is correctly configured, the user is encouraged to test the library prior to use.
+
+In order to do this, install testing requirements and simply run ``pytest``:
+
+.. code-block:: bash
+
+   pip install ngs-toolkit[testing]
+   pytest --pyargs ngs_toolkit
+
+
+Pytest will output summary results (`see for example <https://travis-ci.org/afrendeiro/toolkit/jobs/580167563>`_) and further outputs can be seen in ``${TMPDIR}/pytest-of-${USER}/`` or ``/tmp/pytest-of-${USER}/`` if $TMPDIR is not defined.
