STATUS

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

DESCRIPTION

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

ENVIRONMENT

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).

BUGS

62       Please report any bugs to

SEE ALSO

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.
