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.
