=head1 NAME
Test::Moose - Test functions for Moose specific features
=head1 SYNOPSIS
use Test::More plan => 1;
use Test::Moose;
meta_ok($class_or_obj, "... Foo has a ->meta");
does_ok($class_or_obj, $role, "... Foo does the Baz role");
has_attribute_ok($class_or_obj, $attr_name, "... Foo has the 'bar' attribute");
=head1 DESCRIPTION
This module provides some useful test functions for Moose based classes. It
is an experimental first release, so comments and suggestions are very welcome.
=head1 EXPORTED FUNCTIONS
=over 4
=item B<meta_ok ($class_or_object)>
Tests if a class or object has a metaclass.
=item B<does_ok ($class_or_object, $role, ?$message)>
Tests if a class or object does a certain role, similar to what C<isa_ok>
does for the C<isa> method.
=item B<has_attribute_ok($class_or_object, $attr_name, ?$message)>
Tests if a class or object has a certain attribute, similar to what C<can_ok>
does for the methods.
=back
=head1 TODO
=over 4
=item Convert the Moose test suite to use this module.
=item Here is a list of possible functions to write
=over 4
=item immutability predicates
=item anon-class predicates
=item discovering original method from modified method
=item attribute metaclass predicates (attribute_isa?)

=head1 BUGS
All complex software has bugs lurking in it, and this module is no
exception. If you find a bug please either email me, or add the bug
to cpan-RT.
