# The tests of the Ghostscript drivers happen during build of the ghostscript-testing package:

Testing Ghostscript drivers, so called Ghostscript 'devices'
by running them with the Ghostscript example files
and other test files.

%prep
# Nothing to do here.

%build
# Testing Ghostscript drivers, so called Ghostscript 'devices'
# by running them with the Ghostscript example files
# and other test files,
# (see Source1 README.SUSE).
# Do not let the build fail when one particular gs call fails
# to ensure that during one build always all drivers are tested
# but in case of failures report gs stdout and stderr in the buildlog.
# At the end after all drivers had been tested let the bulid fail
# when at least one particular gs call had failed.
# When gs fails it usually means a driver fails
# but it does not mean it fails when there is wrong output
# i.e. the build succeeds for any output
# cf. "How to test a printer driver package" at
# https://en.opensuse.org/openSUSE:How_to_contribute_to_the_Printing_project

# but many Ghostscript drivers do not work with /dev/null as OutputFile
# so that at least for now only some in practice important example drivers are tested
# that work with /dev/null as OutputFile:
