"as"; very useful if :func:`patch` is creating a mock object for you.
:func:`patch` takes arbitrary keyword arguments. These will be passed to
- the :class:`Mock` (or *new_callable*) on construction.
+ :class:`AsyncMock` if the patched object is asynchronous, to
+ :class:`MagicMock` otherwise or to *new_callable* if specified.
``patch.dict(...)``, ``patch.multiple(...)`` and ``patch.object(...)`` are
available for alternate use-cases.
