NAME
Test::Memory::Cycle - Check for memory leaks and circular memory references VERSION
Version 1.04 SYNOPSIS
Perl's garbage collection has one big problem: Circular references can't get cleaned up. A circular reference can be as simple as two reference that refer to each other: my $mom = { name => "Marilyn Lester", }; my $me = { name => "Andy Lester", mother => $mom, }; $mom->{son} = $me; "Test::Memory::Cycle" is built on top of "Devel::Cycle" to give you an easy way to check for these circular references. use Test::Memory::Cycle; my $object = new MyObject; # Do stuff with the object. memory_cycle_ok( $object ); You can also use "memory_cycle_exists()" to make sure that you have a cycle where you expect to have one. FUNCTIONS
"memory_cycle_ok( $reference, $msg )" Checks that $reference doesn't have any circular memory references. "memory_cycle_exists( $reference, $msg )" Checks that $reference does have any circular memory references. "weakened_memory_cycle_ok( $reference, $msg )" Checks that $reference doesn't have any circular memory references, but unlike "memory_cycle_ok" this will also check for weakened cycles produced with Scalar::Util's "weaken". "weakened_memory_cycle_exists( $reference, $msg )" Checks that $reference does have any circular memory references, but unlike "memory_cycle_exists" this will also check for weakened cycles produced with Scalar::Util's "weaken".

NAME
Test::Dir - test directory attributes SYNOPSIS
use Test::More ...; use Test::Dir; DESCRIPTION
This modules provides a collection of test utilities for directory attributes. Use it in combination with Test::More in your test programs. FUNCTIONS
dir_exists_ok(DIRNAME [, TESTNAME] ) Ok if the directory exists, and not ok otherwise. dir_not_exists_ok(DIRNAME [, TESTNAME] ) Ok if the directory does not exist, and not ok otherwise. dir_empty_ok(DIRNAME [, TESTNAME] ) Ok if the directory is empty (contains no files or subdirectories), and not ok otherwise. dir_not_empty_ok(DIRNAME [, TESTNAME] ) Ok if the directory is not empty, and not ok otherwise. dir_readable_ok(DIRNAME [, TESTNAME] ) Ok if the directory is readable, and not ok otherwise. dir_not_readable_ok(DIRNAME [, TESTNAME] ) Ok if the directory is not readable, and not ok otherwise. dir_writable_ok(DIRNAME [, TESTNAME] ) Ok if the directory is writable, and not ok otherwise. dir_not_writable_ok(DIRNAME [, TESTNAME] ) Ok if the directory is not writable, and not ok otherwise. dir_executable_ok(DIRNAME [, TESTNAME] ) Ok if the directory is executable, and not ok otherwise. dir_not_executable_ok(DIRNAME [, TESTNAME] ) Ok if the directory is not executable, and not ok otherwise. TO DO
I know there are a lot more directory attributes that can be tested. If you need them, please ask (or better yet, contribute code!). AUTHOR
