Reuse existing event loop if one is already running

[medihack]

When I run async tests using pytest-asyncio after integration tests using playwright-pytest (only using playwright.sync_api calls), then those tests fail with the error already described in #359 . I don't know much about the internals of pytest-asyncio, but wouldn't it be possible to reuse the event loop when one is already running (and only try to start a new one when not)?

Just as a note (to help others that stumble upon this) there is a simple workaround. Install nest_asyncio and then put this into the root conftest.py:

def pytest_configure():
    nest_asyncio.apply()
