DeprecationWarning: asyncio.async() function is deprecated, use ensure_future()

[adamrothman]

I am getting a ton of these warnings during test runs:

.tox/py36/lib/python3.6/site-packages/pytest_asyncio/plugin.py:77: DeprecationWarning: asyncio.async() function is deprecated, use ensure_future()
    asyncio.async(pyfuncitem.obj(**testargs), loop=event_loop))

Environment:

• Python 3.6.1
• pytest 3.1.0
• pytest-asyncio 0.5.0

This is because pytest 3.1 integrates the pytest-warnings.

As a quick workaround (specific for pytest-asyncio 0.5.0), I added the option -Wignore:::pytest_asyncio.plugin:77 to the pytest command line.

Acknowledged, thanks for the report.
