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).
