title: 'pytest-asyncio: pytest support for asyncio'
pytest-asyncio is an Apache2 licensed library, written in Python, for
testing asyncio code with pytest.
asyncio code is usually written in the form of coroutines, which makes
it slightly more difficult to test using normal testing tools.
pytest-asyncio provides useful fixtures and markers to make testing
easier.
@pytest.mark.asyncio
async def test_some_asyncio_code():
res = await library.do_something()
assert b"expected result" == res
pytest-asyncio has been strongly influenced by
pytest-tornado.
Features
fixtures for creating and injecting versions of the asyncio event
loop
fixtures for injecting unused tcp/udp ports
pytest markers for treating tests as asyncio coroutines
easy testing with non-default event loops
support for [async def]{.title-ref} fixtures and async generator
fixtures
support auto mode to handle all async fixtures and tests
automatically by asyncio; provide strict mode if a test suite
should work with different async frameworks simultaneously, e.g.
asyncio and trio.
BREAKING: The default asyncio_mode is now strict. [#293](https://github.com/pytest-dev/pytest-asyncio/issues/293) <https://github.com/pytest-dev/pytest-asyncio/issues/293>_
Removes setup.py since all relevant configuration is present setup.cfg. Users requiring an editable installation of pytest-asyncio need to use pip v21.1 or newer. [#283](https://github.com/pytest-dev/pytest-asyncio/issues/283) <https://github.com/pytest-dev/pytest-asyncio/issues/283>_
