The reason why it shows "Not implemented" is that you used
gpgme_set_passphrase_cb () with GPGME_PROTOCOL_CMS.  gpgsm does not
support a passphrase callback in the same way as gpg does.  In
particular gpgme sets up a command line edit handler to push the
passphrase via the callback to to gpg.  gpgsm has no --command-fd option
but only a --passphrase-fd option which can be used with
--pinentry-mode=loopback.

Right, this should be fixed.  I think we already have a feature request
for this.

As a workaround, you should 

  gpgme_set_passphrase_cb (ctx, NULL, NULL);

after switching to GPGME_PROTOCOL_CMS.  This will then use the pinentry
and thus you need to provide a dummy pinentry for your test suite (or
use no passphrase at all).
