Hi, just to clarify, both testing methods I mentioned, is() and is_deeply() are from Test::More. The latter is often enough for comparing two arrays, for example, but if things get more complex then indeed you may want to move up to Test::Deep, which is much more flexible and powerful, providing cmp_deeply(), cmp_bag(), ignore() and other useful tools.

Or, you can do as I do and simply always use: 

use Test::Most 'die';

# tests

done_testing;
__END__

[download]
... because Test::Most provides Test::Deep as well as several other useful libraries (and exports 'die' and loads strict and warnings).

You are right; there are a lot of testing libraries and tools (and you can make your own!). Using them is one of the most satisfying parts of Perl software development, for me.

Hope this helps!


The way forward always starts with a minimal test.
