=head1 NAME

Test::Moose - Test functions for Moose specific features

=head1 VERSION

version 2.1206

=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.

=item B<with_immutable { CODE } @class_names>

Runs B<CODE> (which should contain normal tests) twice, and make each
class in C<@class_names> immutable in between the two runs.

The B<CODE> block is called with a single boolean argument indicating whether
or not the classes have been made immutable yet.
