Both asynccontextmanager and AsyncExitStack do not require asyncio is their implementations. Using asyncio as a helper to write tests is totally OK. For example, I use asyncio to test asynchronous generators (PEP 525). async/await is a generic language feature; asyncio is a framework that uses it. Things like asynccontextmanager are framework agnostic, they can be used in programs built with asyncio, Twisted, Tornado, etc. +1 to put both in contextlib. Yury
