You can't use that.  The regression tests use this to seed the
passphrase cache:

  gpg-preset-passphrase --preset -P def 50B2D4FA4122C212611048BC5FC31BD44393626E

You also need to use the --allow-preset-passphrase in gpg-agent.conf.
Obviously it does not work while generating keys.

Another, more flexible way, is to write your own pinentry which loops
back to your test script.  gpg passes the envvar PINENTRY_USER_DATA all
the way up to the pinentry; this can be used to convey a context.

For testing we have the %no-protection batch parameter:

  $GPG --quiet --batch --gen-key <<EOF
  Key-Type: DSA
  Key-Length: 1024
  Subkey-Type: ELG
  Subkey-Length: 1024
  Name-Real: Harry H.
  Name-Comment: test key 
  Name-Email: hh@@ddorf.de
  Expire-Date: 1
  %no-protection
  %transient-key
  %commit
  EOF
 

Salam-Shalom,

   Werner
