| ``Mock`` objects which are not unsafe will now raise an | |
| ``AttributeError`` when accessing an attribute that matches the name | |
| of an assertion but without the prefix ``assert_``, e.g. accessing | |
| ``called_once`` instead of ``assert_called_once``. | |
| This is in addition to this already happening for accessing attributes | |
| with prefixes ``assert``, ``assret``, ``asert``, ``aseert``, | |
| and ``assrt``. |
