The current way we test this is pretty cheap, i.e. we download previously released macOS dylibs and run against that. Ideally, we would require a full host running the appropriate version of macOS, and we'd execute the tests using SSH on that host. But since we don't have such hosts available easily for now, this is better than nothing. At the same time, also fix some tests that were failing when back deploying.
