Can’t you use Python’s existing CLI <https://docs.python.org/3.6/using/cmdline.html#cmdoption-w> and environment variable <https://docs.python.org/3.6/using/cmdline.html#envvar-PYTHONWARNINGS> to control the ResourceWarning messages?

Warnings where enabled by default when using the “unittest” module in Issue 10535. There is probably a way to disable them, at least by using the “warnings” module directly. But I think ResourceWarning should stay enabled by default when running tests. As you said, the warnings help testing for bugs.
