This PR updates pytest-mock from 1.11.0 to 3.1.0.

Changelog

3.1.0

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

* New mocker fixtures added that allow using mocking functionality in other scopes:

* ``class_mocker``
* ``module_mocker``
* ``package_mocker``
* ``session_mocker``

Added by `scorphus`_ in `182`_.

3.0.0

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

* Python 2.7 and 3.4 are no longer supported. Users using ``pip 9`` or later will install
a compatible version automatically.

* ``mocker.spy`` now also works with ``async def`` functions (`179`_). Thanks `frankie567`_ for the PR!

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.

1.13.0

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

* The object returned by ``mocker.spy`` now also tracks any side effect
of the spied method/function.

1.12.1

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

* Fix error if ``mocker.patch`` is used in code where the source file
is not available, for example stale ``.pyc`` files (`169`_).

.. _169: https://github.com/pytest-dev/pytest-mock/issues/169issuecomment-555729265

1.12.0

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

* Now all patch functions also raise a ``ValueError`` when used
as a context-manager. Thanks `AlexGascon`_ for the PR (`168`_).

1.11.2

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

* The *pytest introspection follows* message is no longer shown
if there is no pytest introspection (`154`_).
Thanks `The-Compiler`_ for the report.

* ``mocker`` now raises a ``ValueError`` when used as a context-manager.
Thanks `binarymason`_ for the PR (`165`_).

.. _165: https://github.com/pytest-dev/pytest-mock/pull/165
.. _binarymason: https://github.com/binarymason

1.11.1

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

* Fix ``mocker.spy`` on Python 2 when used on non-function objects
which implement ``__call__`` (`157`_). Thanks `pbasista`_  for
the report.
