Test::Deep provides deep comparisons of any data structures, including hashes. It is also capable of very advanced testing - what regular expressions do for strings, Test::Deep does for data structures.
use Test::Deep; if (eq_deeply($hash1, $hash2)) { print "they match" }

The fancy stuff comes in when you do something like

$animals = set("cat", "dog"); $people = set("john", "mary"); $a_p = set($animals, $people); print eq_deeply($structure, $a_p);
Ths is an example of testing set equality. It tests that $structure is an array with 2 elemenents (in any order) where each of those elements is an array with 2 elements, one containiing "cat" and "dog" (in any order) the other containing "john" and "mary" (in any order)

When used as part of the Test::Builder framework it gives diagnostics on where the structures differed.

to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
