Changelog

3.13.0

-------------------

* `417 <https://github.com/pytest-dev/pytest-mock/pull/417>`_: ``spy`` now has ``spy_return_list``, which is a list containing all the values returned by the spied function.
* ``pytest-mock`` now requires ``pytest>=6.2.5``.
* `410 <https://github.com/pytest-dev/pytest-mock/pull/410>`_: pytest-mock's ``setup.py`` file is removed.
If you relied on this file, e.g. to install pytest using ``setup.py install``,
please see `Why you shouldn't invoke setup.py directly <https://blog.ganssle.io/articles/2021/10/setup-py-deprecated.html#summary>`_ for alternatives.
