== Tests result: SUCCESS ==

1 test OK.

Total duration: 121 ms
Total tests: run=58
Total test files: run=1/1
Result: SUCCESS

This can be fixed by moving away from legacy @_async_test and by using stabel IsolatedAsyncioTestCase.

def _async_test(func):
"""Decorator to turn an async function into a test case."""
@functools.wraps(func)
def wrapper(*args, **kwargs):
coro = func(*args, **kwargs)
asyncio.run(coro)
return wrapper
