NAME

Test::Memory::Cycle - Check for memory leaks and circular memory references

VERSION

Version 1.00

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 objects 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( $object, $msg )

Checks that $object doesn't have any circular memory references.

memory_cycle_exists( $object, $msg )

Checks that $object does have any circular memory references.
