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 <https://github.com/tobyink/p5-type-tiny/issues>.

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.
