 To run the test suite, ensure you are running a local instance of MongoDB on

+the standard port, and run: ``python setup.py nosetests``.
+
+To run the test suite on every supported Python version and every supported PyMongo version,
+you can use ``tox``.
+tox and each supported Python version should be installed in your environment:
+
+.. code-block:: shell
+
+    # Install tox
+    $ pip install tox
+    # Run the test suites
+    $ tox
+
+If you wish to run one single or selected tests, use the nosetest convention. It will find the folder,
+eventually the file, go to the TestClass specified after the colon and eventually right to the single test.
+Also use the -s argument if you want to print out whatever or access pdb while testing.
+
+.. code-block:: shell
+
+    $ python setup.py nosetests --tests tests/test_django.py:QuerySetTest.test_get_document_or_404 -s
