Test::TypeTiny(3)

NAME
Test::TypeTiny - useful functions for testing the efficacy of type constraints

SYNOPSIS
   use strict;
   use warnings;
   use Test::More;
   use Test::TypeTiny;

   use Types::Mine qw(Integer Number);

   should_pass(1, Integer);
   should_pass(-1, Integer);
   should_pass(0, Integer);
   should_fail(2.5, Integer);

   ok_subtype(Number, Integer);

   done_testing;

STATUS
This module is covered by the Type-Tiny stability policy.

DESCRIPTION
Test::TypeTiny provides a few handy functions for testing type constraints.

  Functions

"should_pass($value, $type, $test_name)"
"should_pass($value, $type)"
    Test that passes iff $value passes "$type->check".

"should_fail($value, $type, $test_name)"
"should_fail($value, $type)"
    Test that passes iff $value fails "$type->check".

"ok_subtype($type, @subtypes)"
    Test that passes iff all @subtypes are subtypes of $type.

"EXTENDED_TESTING"
    Exportable boolean constant.

"matchfor(@things)"
    Assistant for matching exceptions. Not exported by default. See also Test::Fatal::matchfor.

ENVIRONMENT
If the "EXTENDED_TESTING" environment variable is set to true, this module will promote each "should_pass" or "should_fail" test into a subtest block and test the type constraint in both an inlined and non-inlined manner.

This variable must be set at compile time (i.e. before this module is loaded).

BUGS
Please report any bugs to <http://rt.cpan.org/Dist/Display.html?Queue=Type-Tiny>.

SEE ALSO
Type::Tiny.

For an alternative to "should_pass", see Test::Deep::Type which will happily accept a Type::Tiny type constraint instead of a MooseX::Types one.
