# Preliminaries
# =============
#
# Set the variables (The executable is in the build tree). Do the
# basic checks to see if the executable is made or if the defaults
# file exists (basicchecks.sh is in the source tree).
psf=psf.fits
prog=convolve
img=mkprofcat1.fits
execname=../bin/$prog/ast$prog
# Skip?
# =====
#
# If the dependencies of the test don't exist, then skip it. There are two
# types of dependencies:
#
# - The executable was not made (for example due to a configure option),
#
# - The input data was not made (for example the test that created the
# data file failed).
if [ ! -f $execname ]; then echo "$execname not created."; exit 77; fi
if [ ! -f $img ]; then echo "$img does not exist."; exit 77; fi
if [ ! -f $psf ]; then echo "$psf does not exist."; exit 77; fi
# Actual test script
# ==================
#
# 'check_with_program' can be something like Valgrind or an empty
# string. Such programs will execute the command if present and help in
# debugging when the developer doesn't have access to the user's system.
