Changelog

2.0.0

Breaking Changes
++++++++++++++++

* ``mocker.spy`` attributes for tracking returned values and raised exceptions of its spied functions
are now called ``spy_return`` and ``spy_exception``, instead of reusing the existing
``MagicMock`` attributes ``return_value`` and ``side_effect``.

Version ``1.13`` introduced a serious regression: after a spied function using ``mocker.spy``
raises an exception, further calls to the spy will not call the spied function,
always raising the first exception instead: assigning to ``side_effect`` causes
``unittest.mock`` to behave this way (`175`_).

* The deprecated ``mock`` alias to the ``mocker`` fixture has finally been removed.
