###--------------------------------------------------------------------------
### Set up the test cases.
###
### The mdup-test program takes a command-line representation of an mdup_fd
### array, calls mdup, and checks the result.  In particular, it ensures that
### the file descriptors returned are the ones asked for, and that the
### resulting file descriptors actually correspond to the requested files.
### (It does the latter by comparing inodes before and after.)

## Very simple tests.
cases="$cases 3:4"
cases="$cases 4:3"

## Overlapping sources and destinations.
cases="$cases 4:3,3:5,5:6"

## Repeated sources.
cases="$cases 3:4,3:3,3:-1"
cases="$cases 5:8,3:4,3:5,4:6"

## Cycles.
cases="$cases 5:7,3:4,3:5,4:6,5:3"
cases="$cases 5:8,3:4,3:5,4:6,5:3"

###--------------------------------------------------------------------------
### Actually run the tests.

## Initialize counters.
win=0
lose=0
total=0

## Run the tests.
for case in $cases; do
  total=$(expr $total + 1)
  case=$(echo "$case" | sed 'y/,/ /')
  printf "%d: %-60s  " $total "$case"
  if $test $case >mdup.$total.out 2>mdup.$total.err; then
    echo "ok"
    win=$(expr $win + 1)
    rm mdup.$total.out mdup.$total.err
  else
    echo "FAIL"
    lose=$(expr $lose + 1)
  fi
done

## Announce the outcome.
if [ $win = $total ]; then
  echo "All $total tests successful."
  rc=0
else
  echo "FAILED $lose of $total tests."
  rc=1
fi

## And exit.
exit $rc
