'This test ensures that the correct set of methods from `QuerySet`
are copied onto `Manager`.
It\'s particularly useful to prevent accidentally leaking new methods
into `Manager`. New `QuerySet` methods that should also be copied onto
`Manager` will need to be added to `ManagerTest.QUERYSET_PROXY_METHODS`.'
