The problem is that when the test is repeated using the -R, asyncio has cached already StreamReader and StreamWriter into globals, not triggering the warning again.

I'm curious if collections.__getattr__ suffers from the same problem?
asyncio uses basically the same technique for deprecating global names on import.
pablogsal commentedon Jun 4, 2019
Very likely, the problem is that there is no test in test_collections for the deprecation warning, so this situation never happens.
