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);

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

          ok_subtype(Number, Integer);

          done_testing;

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.

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.
