# Since here we're doing black-box testing on the stow executable,
# this looks like it should be robust:
#
#my $STOW = dirname(__FILE__) . '/../bin/stow';
#
# but unfortunately it breaks things like "make distcheck", which
# builds the stow script into a separate path like
#
# stow-2.3.0/_build/sub/bin
#
# before cd'ing to something like
#
# stow-2.3.0/_build/sub
#
# and then running the tests via:
#
# make check-TESTS
# make[2]: Entering directory '/path/to/stow/src/stow-2.3.0/_build/sub'
# dir=../../t; \
# /usr/bin/perl -Ibin -Ilib -I../../t -MTest::Harness -e 'runtests(@ARGV)' "${dir#./}"/*.t
#
# So the simplest solution is to hardcode an assumption that we run
# tests either from somewhere like this during distcheck:
#
# stow-2.3.0/_build/sub
#
# or from the top of the source tree during development. This can be done
# via the following, which also follows the KISS principle:
my $STOW = "$^X bin/stow";
`$STOW --help`;
is($?, 0, "--help should return 0 exit code");
my $err = `$STOW --foo 2>&1`;
is($? >> 8, 1, "unrecognised option should return 1 exit code");
like($err, qr/^Unknown option: foo$/m, "unrecognised option should be listed");
