SYNOPSIS use Test::Warn;

  warning_is    {foo(-dri => "/")} "Unknown Parameter 'dri'", "dri != dir gives warning";
  warnings_are  {bar(1,1)} ["Width very small", "Height very small"];

  warning_is    {add(2,2)} undef, "No warning to calc 2+2"; # or
  warnings_are  {add(2,2)} [],    "No warning to calc 2+2"; # what reads better :-)

  warning_like  {foo(-dri => "/"} qr/unknown param/i, "an unknown parameter test";
  warnings_like {bar(1,1)} [qr/width.*small/i, qr/height.*small/i];

  warning_is    {foo()} {carped => 'didn't found the right parameters'};
  warnings_like {foo()} [qr/undefined/,qr/undefined/,{carped => qr/no result/i}];

  warning_like {foo(undef)}                 'uninitialized';
  warning_like {bar(file => '/etc/passwd')} 'io';

  warning_like {eval q/"$x"; $x;/} 
               [qw/void uninitialized/], 
               "some warnings at compile time";

DESCRIPTION This module provides a few convenience methods for testing warning based code.

If you are not already familiar with the Test::More manpage now would be
the time to go take a look.

THANKS Many thanks to Adrian Howard, chromatic and Michael G. Schwern, who all had given me a lot of ideas.
