 Alternatively, there are the py27 and py35 tox jobs which will run the unit
 tests with the corresponding version of python.
 
+One common activity is to just run a single test, you can do this with tox
+simply by specifying to just run py27 or py35 tests against a single test::
+
+    $ tox -e py27 -- -n tempest.tests.test_microversions.TestMicroversionsTestsClass.test_config_version_none_23
+
+Or all tests in the test_microversions.py file::
+
+    $ tox -e py27 -- -n tempest.tests.test_microversions
+
+You may also use regular expressions to run any matching tests::
+
+    $ tox -e py27 -- test_microversions
+
+Additionally, when running a single test, or test-file, the ``-n/--no-discover``
+argument is no longer required, however it may perform faster if included.
+
+For more information on these options and details about stestr, please see the
+`stestr documentation <http://stestr.readthedocs.io/en/latest/MANUAL.html>`_.
