Comment:
your test plan sounds reasonable - selftest provisions a client config via write_clientconf (in selftest/selftest.pl), so you might be able to pass that path down to your test for restoration. I'd suggest raising this question directly on the samba-technical at lists.samba.org , as you'll reach a much wider audience.
