Anytime something is changed in the Core, all existing unit tests must be run to ensure that nothing was broken. Adding unit tests """"""""""""""""" The use of unit tests is strongly encouraged. Every time a new feature is introduced or an existing one is modified, a unit test should be added. Conventions for unit tests """""""""""""""""""""""""" Unit tests should be as concise as possible. Since the :code:`setUp()` and :code:`tearDown()` methods always have the same responsibility, these methods do *not* need a documentation block. Since unit tests never return anything, they do not need an :code:`@return` tag.
