30 Test::TypeTiny provides a few handy functions for testing type
31 constraints.
32
33 Functions
34 "should_pass($value, $type, $test_name)"
35 "should_pass($value, $type)"
36 Test that passes iff $value passes "$type->check".
37
38 "should_fail($value, $type, $test_name)"
39 "should_fail($value, $type)"
40 Test that passes iff $value fails "$type->check".
41
42 "ok_subtype($type, @subtypes)"
43 Test that passes iff all @subtypes are subtypes of $type.
44
45 "EXTENDED_TESTING"
46 Exportable boolean constant.
47
48 "matchfor(@things)"
49 Assistant for matching exceptions. Not exported by default. See
50 also Test::Fatal::matchfor.
51
53 If the "EXTENDED_TESTING" environment variable is set to true, this
54 module will promote each "should_pass" or "should_fail" test into a
55 subtest block and test the type constraint in both an inlined and non-
56 inlined manner.
57
58 This variable must be set at compile time (i.e. before this module is
59 loaded).

66 Type::Tiny.
67
68 For an alternative to "should_pass", see Test::Deep::Type which will
69 happily accept a Type::Tiny type constraint instead of a MooseX::Types
70 one.
