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.
