`pytest-asyncio <https://pytest-asyncio.readthedocs.io/en/latest/>`_ is a `pytest <https://docs.pytest.org/en/latest/contents.html>`_ plugin. It facilitates testing of code that uses the `asyncio <https://docs.python.org/3/library/asyncio.html>`_ library.
Specifically, pytest-asyncio provides support for coroutines as test functions. This allows users to *await* code inside their tests. For example, the following code is executed as a test item by pytest:
.. code-block:: python
@pytest.mark.asyncio
async def test_some_asyncio_code():
res = await library.do_something()
assert b"expected result" == res
More details can be found in the `documentation <https://pytest-asyncio.readthedocs.io/en/latest/>`_.
Note that test classes subclassing the standard `unittest <https://docs.python.org/3/library/unittest.html>`__ library are not supported. Users
are advised to use `unittest.IsolatedAsyncioTestCase <https://docs.python.org/3/library/unittest.html#unittest.IsolatedAsyncioTestCase>`__
or an async framework such as `asynctest <https://asynctest.readthedocs.io/en/latest>`__.
pytest-asyncio is available under the `Apache License 2.0 <https://github.com/pytest-dev/pytest-asyncio/blob/main/LICENSE>`_.
Installation
------------
To install pytest-asyncio, simply:
.. code-block:: bash
$ pip install pytest-asyncio
This is enough for pytest to pick up pytest-asyncio.
Contributing
------------
Contributions are very welcome. Tests can be run with ``tox``, please ensure
the coverage at least stays the same before you submit a pull request.
