-Test::Moose - Test functions for Moose specific features
+ use Test::More plan => 1;
+ use Test::Moose;
-=head1 SYNOPSIS
+ 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, $attr_name, "... Foo has the 'bar' attribute");
- use Test::Moose plan => 1;
+=head1 DESCRIPTION
- does_ok ($class,$role,"Does $class do $role");
+This module provides some useful test functions for Moose based classes. It
+is an experimental first release, so comments and suggestions are very welcome.

-=item does_ok
+=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)>
- does_ok ($class,$role,$name);
+Tests if a class or object has a certain attribute, similar to what C<can_ok>
+does for the methods.
-Tests if a class does a certain role, similar to what isa_ok does for
-isa.
+=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.
