NAME

       Test::Deep::UnorderedPairs - A Test::Deep plugin for comparing an unordered list of tuples

VERSION

       version 0.006

SYNOPSIS

           use Test::More;
           use Test::Deep;
           use Test::Deep::UnorderedPairs;

           cmp_deeply(
               {
                   inventory => [
                       pear => 6,
                       peach => 5,
                       apple => 1,
                   ],
               },
               {
                   inventory => unordered_pairs(
                       apple => 1,
                       peach => ignore,
                       pear => 6,
                   ),
               },
               'got the right inventory',
           );

DESCRIPTION

       This module provides the sub "unordered_pairs" (and "tuples", "samehash", as synonyms) to
       indicate the data being tested is a list of pairs that should be tested where the order of
       the pairs is insignificant.

       This is useful when testing a function that returns a list of hash elements as an
       arrayref, not a hashref.  One such application might be testing PSGI headers, which are
       passed around as an arrayref:

           my $response = [
               '200',
               [
                   'Content-Length' => '12',
                   'Content-Type' => 'text/plain',
               ],
               [ 'hello world!' ],
           ];

           # this test passes
           cmp_deeply(
               $response,
               [
                   '200',
                   unordered_pairs(
                       'Content-Type' => 'text/plain',
                       'Content-Length' => '12',
                   ],
                   [ 'hello world!' ],
               ],
               'check headers as an arrayref of unordered pairs',
           );

FUNCTIONS

   "unordered_pairs"
       Pass an (even-numbered) list of items to test

   "tuples", "samehash"
       "tuples" and "samehash" are aliases for "unordered_pairs".  I'm open to more names as
       well; I'm not quite yet sure what the best nomenclature should be.

       (Be aware that ""samehash"" is a bit of a misnomer, since if a key is repeated, the
       comparison is not equivalent to comparing as a hash.)
