The package specifically only extends mock_ and not any other part of unittest.

.. _mock: https://mock.readthedocs.io/en/latest/


.. note::
   Mock 4.0+ (included within Python 3.8+) now includes an awaitable mock ``mock.AsyncMock``. 
   This is recommended for new projects.


Installation
============

Install using *pip*:

.. code-block:: bash

    pip install asyncmock


Usage
=====

Async Mock is a drop in replacement for a `Mock` object eg:

.. code-block:: python

    my_mock = AsyncMock()

    await my_mock("foo", bar=123)

    my_mock.assert_called_with("foo", bar=123)


This also works with nested methods:

.. code-block:: python

    my_mock = AsyncMock()

    await my_mock.my_method("foo", bar=123)

    my_mock.my_method.assert_called_with("foo", bar=123)


Side effects and return values can also be awaited.

Including a non-awaitable item:

.. code-block:: python

    my_mock = AsyncMock()

    my_mock.my_method.not_async = True
    my_mock.my_method("foo", bar=123)


The `not_async` option can also be provided as an init argument. The `not_async` 
argument is not inherited by sub-mocks.


pytest Example
==============

These examples use pytest_ along with the pytest-asyncio_ plugin.

.. _pytest: https://docs.pytest.org/en/latest/
.. _pytest-asyncio: https://github.com/pytest-dev/pytest-asyncio


Generating an exception:

.. code-block:: python

    @pytest.mark.asyncio
    async def test_raise_exception():
        my_mock = AsyncMock(side_effect=KeyError)

        with pytest.raises(KeyError):
            await my_mock()

        my_mock.assert_called()
