Security Advisories (1)
CVE-2025-40909 (2025-05-30)

Perl threads have a working directory race condition where file operations may target unintended paths. If a directory handle is open at thread creation, the process-wide current working directory is temporarily changed in order to clone that handle for the new thread, which is visible from any third (or more) thread already running. This may lead to unintended operations such as loading code or accessing files from unexpected locations, which a local attacker may be able to exploit. The bug was introduced in commit 11a11ecf4bea72b17d250cfb43c897be1341861e and released in Perl version 5.13.6

NAME

Test2::Tools::Class - Test2 implementation of the tools for testing classes.

DESCRIPTION

Test2 based tools for validating classes and objects. These are similar to some tools from Test::More, but they have a more consistent interface.

SYNOPSIS

use Test2::Tools::Class;

isa_ok($CLASS_OR_INSTANCE, $PARENT_CLASS1, $PARENT_CLASS2, ...);
isa_ok($CLASS_OR_INSTANCE, [$PARENT_CLASS1, $PARENT_CLASS2, ...], "Test Name");

can_ok($CLASS_OR_INSTANCE, $METHOD1, $METHOD2, ...);
can_ok($CLASS_OR_INSTANCE, [$METHOD1, $METHOD2, ...], "Test Name");

DOES_ok($CLASS_OR_INSTANCE, $ROLE1, $ROLE2, ...);
DOES_ok($CLASS_OR_INSTANCE, [$ROLE1, $ROLE2, ...], "Test Name");

EXPORTS

All subs are exported by default.

can_ok($thing, @methods)
can_ok($thing, \@methods, $test_name)

This checks that $thing (either a class name, or a blessed instance) has the specified methods.

If the second argument is an arrayref then it will be used as the list of methods leaving the third argument to be the test name.

isa_ok($thing, @classes)
isa_ok($thing, \@classes, $test_name)

This checks that $thing (either a class name, or a blessed instance) is or subclasses the specified classes.

If the second argument is an arrayref then it will be used as the list of classes leaving the third argument to be the test name.

DOES_ok($thing, @roles)
DOES_ok($thing, \@roles, $test_name)

This checks that $thing (either a class name, or a blessed instance) does the specified roles.

If the second argument is an arrayref then it will be used as the list of roles leaving the third argument to be the test name.

Note 1: This uses the $class->DOES(...) method, not the does() method Moose provides.

Note 2: Not all perls have the DOES() method, if you use this on those perls the test will be skipped.
