------

*2025-09-16*

* `529 <https://github.com/pytest-dev/pytest-mock/issues/529>`_: Fixed ``itertools._tee object has no attribute error`` -- now ``duplicate_iterators=True`` must be passed to ``mocker.spy`` to duplicate iterators.

3.15.0

------

*2025-09-04*

* Python 3.8 (EOL) is no longer supported.
* `524 <https://github.com/pytest-dev/pytest-mock/pull/524>`_: Added ``spy_return_iter`` to ``mocker.spy``, which contains a duplicate of the return value of the spied method if it is an ``Iterator``.

3.14.0

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

* `415 <https://github.com/pytest-dev/pytest-mock/pull/415>`_: ``MockType`` and ``AsyncMockType`` can be imported from ``pytest_mock`` for type annotation purposes.

* `420 <https://github.com/pytest-dev/pytest-mock/issues/420>`_: Fixed a regression which would cause ``mocker.patch.object`` to not being properly cleared between tests.

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.

3.11.0

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

* Fixed introspection for failed ``assert_has_calls`` (`365`_).

* Updated type annotations for ``mocker.patch`` and ``mocker.spy`` (`364`_).

.. _365: https://github.com/pytest-dev/pytest-mock/pull/365
.. _364: https://github.com/pytest-dev/pytest-mock/pull/364

3.10.0

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

* Added new ``mocker.stop(m)`` method to stop specific ``mocker.patch`` or ``mocker.spy`` calls (`319`_).

.. _319: https://github.com/pytest-dev/pytest-mock/pull/319

3.9.0

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

* Expose ``NonCallableMagicMock`` via the ``mocker`` fixture (`318`_).

.. _318: https://github.com/pytest-dev/pytest-mock/pull/318

3.8.2

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

- Fixed ``AsyncMock`` support for Python 3.7+ in ``mocker.async_stub`` (`302`_).

.. _298: https://github.com/pytest-dev/pytest-mock/issues/298

3.8.0

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

* Add ``MockerFixture.async_mock`` method. Thanks `PerchunPak`_ for the PR (`296`_).

.. _PerchunPak: https://github.com/PerchunPak
.. _296: https://github.com/pytest-dev/pytest-mock/pull/296

3.7.0

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

* Python 3.10 now officially supported.
* Dropped support for Python 3.6.

3.6.1

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

* Fix ``mocker.resetall()`` when using ``mocker.spy()`` (`237`_). Thanks `blaxter`_ for the report and `shadycuz`_ for the PR.

.. _blaxter: https://github.com/blaxter
.. _shadycuz: https://github.com/shadycuz
.. _237: https://github.com/pytest-dev/pytest-mock/issues/237

3.6.0

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

* pytest-mock no longer supports Python 3.5.

* Correct type annotations for ``mocker.patch.object`` to also include the string form.
Thanks `plannigan`_ for the PR (`235`_).

* ``reset_all`` now supports ``return_value`` and ``side_effect`` keyword arguments. Thanks `alex-marty`_ for the PR (`214`_).

.. _plannigan: https://github.com/plannigan
.. _214: https://github.com/pytest-dev/pytest-mock/pull/214
.. _235: https://github.com/pytest-dev/pytest-mock/pull/235

3.5.1

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

* Use ``inspect.getattr_static`` instead of resorting to ``object.__getattribute__``
magic. This should better comply with objects which implement a custom descriptor
protocol. Thanks `yesthesoup`_ for the PR (`224`_).

.. _yesthesoup: https://github.com/yesthesoup
.. _224: https://github.com/pytest-dev/pytest-mock/pull/224

3.5.0

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

* Now all patch functions will emit a warning instead of raising a ``ValueError`` when used
as a context-manager. Thanks `iforapsy`_ for the PR (`221`_).

* Additionally, ``mocker.patch.context_manager`` is available when the user intends to mock
a context manager (for example  ``threading.Lock`` object), which will not emit that
warning.

.. _iforapsy: https://github.com/iforapsy
.. _221: https://github.com/pytest-dev/pytest-mock/pull/221

3.4.0

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

* Add `mock.seal` alias to the `mocker` fixture (`211`_). Thanks `coiax`_ for the PR.

* Fixed spying on exceptions not covered by the ``Exception``
superclass (`215`_), like ``KeyboardInterrupt`` -- PR `216`_
by `webknjaz`_.

Before the fix, both ``spy_return`` and ``spy_exception``
were always assigned to ``None``
whenever such an exception happened. And after this fix,
``spy_exception`` is set to a correct value of an exception
that has actually happened.

.. _216: https://github.com/pytest-dev/pytest-mock/pull/216

3.3.1

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

* Introduce ``MockFixture`` as an alias to ``MockerFixture``.

Before ``3.3.0``, the fixture class was named ``MockFixture``, but was renamed to ``MockerFixture`` to better
match the ``mocker`` fixture. While not officially part of the API, it was later discovered that this broke
the code of some users which already imported ``pytest_mock.MockFixture`` for type annotations, so we
decided to reintroduce the name as an alias.

Note however that this is just a stop gap measure, and new code should use ``MockerFixture`` for type annotations.

* Improved typing for ``MockerFixture.patch``  (`201`_). Thanks `srittau`_ for the PR.

.. _srittau: https://github.com/srittau
.. _201: https://github.com/pytest-dev/pytest-mock/pull/201

3.3.0

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

* ``pytest-mock`` now includes inline type annotations and exposes them to user programs. The ``mocker`` fixture returns ``pytest_mock.MockerFixture``, which can be used to annotate your tests:

.. code-block:: python

     from pytest_mock import MockerFixture

     def test_foo(mocker: MockerFixture) -> None:
         ...

The type annotations were developed against mypy version ``0.782``, the
minimum version supported at the moment. If you run into an error that you believe to be incorrect, please open an issue.

Many thanks to `staticdev`_ for providing the initial patch (`199`_).

.. _staticdev: https://github.com/staticdev
.. _199: https://github.com/pytest-dev/pytest-mock/pull/199

3.2.0

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

* `AsyncMock <https://docs.python.org/3/library/unittest.mock.html#unittest.mock.AsyncMock>`__ is now exposed in ``mocker`` and supports provides assertion introspection similar to ``Mock`` objects.

Added by `tirkarthi`_ in `197`_.

.. _tirkarthi: https://github.com/tirkarthi
.. _197: https://github.com/pytest-dev/pytest-mock/pull/197

3.1.1

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

* Fixed performance regression caused by the ``ValueError`` raised
when ``mocker`` is used as context manager (`191`_).

.. _191: https://github.com/pytest-dev/pytest-mock/issues/191

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`_.

.. _scorphus: https://github.com/scorphus
.. _182: https://github.com/pytest-dev/pytest-mock/pull/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!

.. _179: https://github.com/pytest-dev/pytest-mock/issues/179
.. _frankie567: https://github.com/frankie567

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.

.. _175: https://github.com/pytest-dev/pytest-mock/issues/175

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/169#issuecomment-555729265

1.12.0

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

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

.. _AlexGascon: https://github.com/AlexGascon
.. _168: https://github.com/pytest-dev/pytest-mock/pull/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`_).

which implement ``__call__`` (`157`_). Thanks `pbasista`_  for
the report.

.. _157: https://github.com/pytest-dev/pytest-mock/issues/157
.. _pbasista: https://github.com/pbasista

* Fix ``setup.py`` to correctly read the ``README.rst``. Thanks `ghisvail`_ for the fix (`107`_).

.. _107: https://github.com/pytest-dev/pytest-mock/issues/107

1.7.0

-----

.. _102: https://github.com/pytest-dev/pytest-mock/issues/102

1.6.3

-----

* Fix ``UnicodeDecodeError`` during assert introspection in ``assert_called_with`` in Python 2.
Thanks `AndreasHogstrom`_ for the report (`91`_).


.. _AndreasHogstrom: https://github.com/AndreasHogstrom

.. _91: https://github.com/pytest-dev/pytest-mock/issues/91

1.6.2

-----

* Provide source package in ``tar.gz`` format and remove obsolete ``MANIFEST.in``.

1.6.1

-----

* Fix ``mocker.resetall()`` by ignoring mocker objects which don't have a
``resetall`` method, like for example ``patch.dict``.
Thanks `jdavisp3`_ for the PR (`88`_).

.. _jdavisp3: https://github.com/jdavisp3

.. _88: https://github.com/pytest-dev/pytest-mock/pull/88

1.6.0

-----

* The original assertions raised by the various ``Mock.assert_*`` methods
now appear in the failure message, in addition to the message obtained from
pytest introspection.
Thanks `quodlibetor`_ for the initial patch (`79`_).

.. _quodlibetor: https://github.com/quodlibetor

.. _79: https://github.com/pytest-dev/pytest-mock/pull/79

1.5.0

-----

* New ``mocker.mock_module`` variable points to the underlying mock module being used
(``unittest.mock`` or ``mock``).
Thanks `blueyed`_ for the request (`71`_).

.. _71: https://github.com/pytest-dev/pytest-mock/pull/71

1.4.0

-----

* New configuration variable, ``mock_use_standalone_module`` (defaults to ``False``). This forces
the plugin to import ``mock`` instead of ``unittest.mock`` on Python 3. This is useful to import
a newer version than the one available in the Python distribution.

* Previously the plugin would first try to import ``mock`` and fallback to ``unittest.mock``
in case of an ``ImportError``, but this behavior has been removed because it could hide
hard to debug import errors (`68`_).

* Now ``mock`` (Python 2) and ``unittest.mock`` (Python 3) are lazy-loaded to make it possible to
implement the new ``mock_use_standlone_module`` configuration option. As a consequence of this
the undocumented ``pytest_mock.mock_module`` variable, which pointed to the actual mock module
being used by the plugin, has been removed.

* `DEFAULT <https://docs.python.org/3/library/unittest.mock.html#default>`_ is now available from
the ``mocker`` fixture.

.. _68: https://github.com/pytest-dev/pytest-mock/issues/68

1.3.0

-----

* Add support for Python 3.6. Thanks `hackebrot`_ for the report (`59`_).

* ``mock.mock_open`` is now aliased as ``mocker.mock_open`` for convenience.
Thanks `pokidovea`_ for the PR (`66`_).

.. _59: https://github.com/pytest-dev/pytest-mock/issues/59
.. _66: https://github.com/pytest-dev/pytest-mock/pull/66

1.2

---

* Try to import ``mock`` first instead of ``unittest.mock``. This gives the user flexibility
to install a newer ``mock`` version from PyPI instead of using the one available in the
Python distribution.
Thanks `wcooley`_ for the PR (`54`_).

* ``mock.sentinel`` is now aliased as ``mocker.sentinel`` for convenience.
Thanks `kjwilcox`_ for the PR (`56`_).

.. _kjwilcox: https://github.com/kjwilcox
.. _54: https://github.com/pytest-dev/pytest-mock/issues/54
.. _56: https://github.com/pytest-dev/pytest-mock/pull/56

1.1

---

* From this version onward, ``pytest-mock`` is licensed under the `MIT`_ license (`45`_).

* Now the plugin also adds introspection information on differing call arguments when
calling helper methods such as ``assert_called_once_with``. The extra introspection
information is similar to pytest's and can be disabled with the ``mock_traceback_monkeypatch``
option.
Thanks `asfaltboy`_ for the PR (`36`_).

* ``mocker.stub()`` now allows passing in the name for the constructed ``Mock``
object instead of having to set it using the internal ``_mock_name`` attribute
directly. This is useful for debugging as the name is used in the mock's
``repr`` string as well as related assertion failure messages.
Thanks `jurko-gospodnetic`_ for the PR (`40`_).

* Monkey patching ``mock`` module for friendlier tracebacks is automatically disabled
with the ``--tb=native`` option. The underlying
mechanism used to suppress traceback entries from ``mock`` module does not work with that option
anyway plus it generates confusing messages on Python 3.5 due to exception chaining (`44`_).
Thanks `blueyed`_ for the report.

* ``mock.call`` is now aliased as ``mocker.call`` for convenience.
Thanks `jhermann`_ for the PR (`49`_).

(`42`_). Thanks `blueyed`_ for the PR.

.. _blueyed: https://github.com/blueyed
.. _42: https://github.com/pytest-dev/pytest-mock/issues/42

0.11.0

------

* `PropertyMock <https://docs.python.org/3/library/unittest.mock.html#unittest.mock.PropertyMock>`_
is now accessible from ``mocker``.
Thanks `satyrius`_ for the PR (`32`_).

* Fix regression using one of the ``assert_*`` methods in patched
functions which receive a parameter named ``method``.

0.10.1

------

* Fix regression in frozen tests due to ``distutils`` import dependency.
Thanks `The-Compiler`_ for the report (`29`_).

* Fix regression when using ``pytest-mock`` with ``pytest-2.7.X``.
Thanks `akscram`_ for the report (`28`_).

.. _28: https://github.com/pytest-dev/pytest-mock/issues/28
.. _29: https://github.com/pytest-dev/pytest-mock/issues/29

0.10

----

* ``pytest-mock`` now monkeypatches the ``mock`` library to improve pytest output
for failures of mock call assertions like ``Mock.assert_called_with()``.
Thanks to `Chronial`_ for idea and PR (`26`_, `27`_)!

.. _Chronial: https://github.com/Chronial
.. _26: https://github.com/pytest-dev/pytest-mock/issues/26
.. _27: https://github.com/pytest-dev/pytest-mock/issues/27

0.9.0

-----

* New ``mocker.resetall`` function, which calls ``reset_mock()`` in all mocked
objects up to that point. Thanks to `mathrick`_ for the PR!

0.8.1

-----

* ``pytest-mock`` is now also available as a wheel. Thanks `rouge8`_ for the PR!

0.8.0

-----

* ``mock.ANY`` is now accessible from the mocker fixture (`17`_), thanks `tigarmo`_ for the PR!

.. _17: https://github.com/pytest-dev/pytest-qt/issues/17

0.7.0

-----

Thanks to `fogo`_, mocker.spy can now prey upon staticmethods and classmethods. :smile:

0.6.0

-----

* Two new auxiliary methods, ``spy`` and ``stub``. See ``README`` for usage.
(Thanks `fogo`_ for complete PR!)

0.5.0

-----

* ``Mock`` and ``MagicMock`` are now accessible from the ``mocker`` fixture,
many thanks to `marcwebbie`_ for the complete PR!

0.4.3

-----

* ``mocker`` fixture now returns the same object (`8`_). Many thanks to `RonnyPfannschmidt`_ for the PR!

.. _8: https://github.com/pytest-dev/pytest-qt/issues/8

0.4.2

-----

* Small fix, no longer using wheel as an alternate package since it
conditionally depends on mock module based on Python version,
as Python >= 3.3 already includes ``unittest.mock``.
Many thanks to `The-Compiler`_ for letting me know and providing a PR with the fix!

0.4.1

-----

* Small release that just uses ``pytest_mock`` as the name of the plugin,
instead of ``pytest-mock``: this makes it simple to depend on this plugin
explicitly using ``pytest_plugins`` module variable mechanism.

0.4.0

-----

* Changed fixture name from ``mock`` into ``mocker`` because it conflicted
with the actual mock module, which made using it awkward when access to both
the module and the fixture were required within a test.

Thanks `kmosher`_ for request and discussion in `4`_. :smile:

.. _4: https://github.com/pytest-dev/pytest-qt/issues/4

0.3.0

-----

* Fixed bug `2`_, where a patch would not be uninstalled correctly after
patching the same object twice.

0.2.0

-----

* Added ``patch.dict`` support.

0.1.0

-----

First release.
