The Unpaid Backbone of Open Source: Solo Maintainers Face Increasing Security Demands
Solo open source maintainers face burnout and security challenges, with 60% unpaid and 60% considering quitting.
########## Async Mock ##########
Awaitable mocks for async code.

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.
Install using pip:
.. code-block:: bash
pip install asyncmock
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.
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()
