89 # ABSTRACT: Test functions for Moose specific features
97 use Test::More plan => 1;
100 meta_ok($class_or_obj, "... Foo has a ->meta");

102 has_attribute_ok($class_or_obj, $attr_name, "... Foo has the 'bar' attribute");
106 This module provides some useful test functions for Moose based classes. It
107 is an experimental first release, so comments and suggestions are very welcome.
109 =head1 EXPORTED FUNCTIONS
113 =item B<meta_ok ($class_or_object)>
115 Tests if a class or object has a metaclass.
117 =item B<does_ok ($class_or_object, $role, ?$message)>
119 Tests if a class or object does a certain role, similar to what C<isa_ok>
120 does for the C<isa> method.
122 =item B<has_attribute_ok($class_or_object, $attr_name, ?$message)>
124 Tests if a class or object has a certain attribute, similar to what C<can_ok>
125 does for the methods.
127 =item B<with_immutable { CODE } @class_names>
129 Runs B<CODE> (which should contain normal tests) twice, and make each
130 class in C<@class_names> immutable in between the two runs.
138 =item Convert the Moose test suite to use this module.
140 =item Here is a list of possible functions to write
144 =item immutability predicates
146 =item anon-class predicates
148 =item discovering original method from modified method
150 =item attribute metaclass predicates (attribute_isa?)
