I think the issue comes down to: how do I compare two arrays for equality. Note: the equality test needs to sort the arrays first or ignore array order

is_deeply is the best way to compare two data structures for equality. If the order of an array doesn't matter in the test, then it's fine to sort first: is_deeply([sort @got_files], [sort @expected_files]); (or you can sort the arrays earlier if you like). The other way to hold unsorted data would be with a hash (the difference being that an array allows duplicate values while a hash does not allow duplicate keys, and that an array will keep the order of its values while a hash will not), however is_deeply can also easily compare two hashes. So e.g. my %files = map { $_ => 1 } @files; is_deeply \%files, \%expect_files;
