# Tests to ensure that the monkeysphere is working

# these tests might be best run under fakeroot, particularly the
# "server-side" tests.  Using fakeroot, they should be able to be run
# as a non-privileged user.

# NOTE: these tests have *not* themselves been tested yet
# (2008-09-13).  Please exercise with caution!

# these tests assume a commonly-trusted "Admin's key", a fake key
# permanently stored in ./admin:

gpgadmin() {
    GNUPGHOME=./admin gpg "$@"
}


# cleanup:

cleanup() {
    # FIXME: stop the sshd process

    rm -f "$SOCKET"

    # FIXME: how should we clear out the temporary $VARLIB?

    # FIXME: clear out ssh client config file and known hosts.
}

## set up some variables to ensure that we're operating strictly in
## the tests, not system-wide:

TESTDIR=$(pwd)
export MONKEYSPHERE_SYSDATADIR="$TESTDIR"/var
export MONKEYSPHERE_SYSCONFIGDIR="$TESTDIR"/etc
export SOCKET="$TESTDIR"/ssh-socket

### SERVER TESTS

# Use the local copy of executables first, instead of system ones.
# This should help us test without installing.
export PATH="$TESTDIR"/../src:"$TESTDIR"/../src/keytrans:"$PATH"
export MONKEYSPHERE_SHARE="$TESTDIR"/../src

# create a new host key

echo | monkeysphere-server gen-key --expire 2d

HOSTKEYID=$( monkeysphere-server show-key | tail -n1 | cut -f3 -d\  )

# certify it with the "Admin's Key".
# (this would normally be done via keyservers)
monkeysphere-server gpg-authentication-cmd "--armor --export $HOSTKEYID" | gpgadmin --import

gpgadmin --sign-key "$HOSTKEYID"

# FIXME: how can we test publish-key without flooding junk into the
# keyservers?

# indicate that the "Admin's" key is an identity certifier for the
# host

monkeysphere-server add-identity-certifier ./home/admin/.gnupg/pubkey.gpg

# write the sshd_config
cat <<EOF > "$TESTDIR"/etc/ssh/sshd_config
HostKey ${TESTDIR}/etc/ssh/ssh_host_rsa_key
EOF

# launch sshd with the new host key.

mkfifo "$SOCKET"

/usr/sbin/sshd -f "$TESTDIR"/etc/ssh/sshd_config -i <>"$SOCKET"



### TESTUSER TESTS

# connect to sample sshd host key, using monkeysphere to verify the
# identity before connection.

## FIXME: implement!

# create a new client side key, certify it with the "CA", use it to
# log in.
