Once we have a gMSA server side the impact of deleting root keys becomes real and so we must do this in a quiet place where it can not impact on other things. Likewise, we want the samba.tests.dsdb_quiet_provision_tests tests to run somewhere that is not doing other things, so we can see what a bare provision will do. We must not allow test ordering inside the file to cause tests that create root keys to run before checking if provision created a usable root key.
