use Test::More tests => 1; use Test::Singleton; is_singleton( "Some::Class", "new", "instance" );
** If you are unfamiliar with testing read Test::Tutorial first! **
This is asimple, basic module for checking whether a class is a Singleton. A Singleton describes an object class that can have only one instance in any system. An example of a Singleton might be a print spooler or system registry, or any kind of central dispatcher.
For a description and discussion of the Singleton class, see "Design Patterns", Gamma et al, Addison-Wesley, 1995, ISBN 0-201-63361-2.
