Not documented.  The GPGME test suite does this, however.

Never done that.

Yes.  In GPGME, we also use the old passphrase-fd mechanism for gpg
(for this, we unset GPG_AGENT_INFO).

However, for a function like genkey this is not sufficient.

Right.

This is possible, but such a pinentry has not been implemented yet.
It would be quite easy to script one, though, as it does not have to
do much.

You could also use the preset passphrase mechanism of gpg-agent.
However, it would be good idea to start a new gpg-agent for the test
session then for cleanliness.

Applied, thanks.

Should already be the case.  In doc/gnupg.texi:

@direntry
* gpg2: (gnupg).           OpenPGP encryption and signing tool.
* gpgsm: (gnupg).          S/MIME encryption and signing tool.
@end direntry

Thanks,
