 All unit tests should be run using tox. To run Ironic's entire test suite::

 To run a specific test or tests, use the "-e" option followed by the tox target
 name. For example::
 
-    # run the unit tests under py27 and also run the pep8 tests
-    tox -epy27 -epep8

+    tox -epy36 -epep8
 
 You may pass options to the test programs using positional arguments.
 To run a specific unit test, this passes the desired test
