The relevant part of the test script is
# Build a wrapper script to launch gimp
cat > gimp-launch.sh << EOF
/usr/bin/gimp -i -b "(mmtests-open-image \"$FILENAME\")" -b "(gimp-quit 0)" > $LOGDIR_RESULTS/gimp-out.1 2>&1
echo \$? > gimp-exit-code
chmod u+x gimp-launch.sh
$TIME_CMD xinit ./gimp-launch.sh 2> $LOGDIR_RESULTS/time.1
It's clumsy because the application would start with no window manager
and looking at it again, it probably was not even necessary because of
the -i switch in gimp.
Previously when I needed to automate an X app I configured the machine to
login automatically, exported the DISPLAY variable in the test script and
used wmctrl to detect if an application had a window displayed yet.
