def fixture_logging_setup(request):
    """
    Not exactly sure why :/ but, this fixture needs to be scoped to function level and not
    session or class. If you invoke pytest with tests across multiple test classes, when scopped
    at session, the root logger appears to get reset between each test class invocation.
    this means that the first test to run not from the first test class (and all subsequent
    tests), will have the root logger reset and see a level of NOTSET. Scoping it at the
    class level seems to work, and I guess it's not that much extra overhead to setup the
    logger once per test class vs. once per session in the grand scheme of things.
