Error reproducing an example from the REAME.md

I reproduced the app example given in the README.txt and I got the following error:

I run pytest -s test_app.py on a new environment with the installed packages explained in the README. Here is my pip list:

Sounds like pytest fixture is returning an async iterable instead the value in the yield.
Could it be caused by some bug in some version of some package, or is a problem of the asgi-lifespan? Or I mess up with my setting?

Hi!

Yes, it’s likely the latest version of pytest-asyncio switched how async fixtures should be declared. I believe they should be @pytest_asyncio.fixture now, or something.

If you figure out this fixes the issue, I’d be happy to review a PR to update the README. :)

You were right about the problem and the solution.
I have updated the README.md in the PR #52
