100 This module provides some useful test functions for Moose based classes. It
101 is an experimental first release, so comments and suggestions are very welcome.
103 =head1 EXPORTED FUNCTIONS
107 =item B<meta_ok ($class_or_object)>
109 Tests if a class or object has a metaclass.
111 =item B<does_ok ($class_or_object, $role, ?$message)>
113 Tests if a class or object does a certain role, similar to what C<isa_ok>
114 does for the C<isa> method.
116 =item B<has_attribute_ok($class_or_object, $attr_name, ?$message)>
118 Tests if a class or object has a certain attribute, similar to what C<can_ok>
119 does for the methods.
121 =item B<with_immutable { CODE } @class_names>
123 Runs B<CODE> (which should contain normal tests) twice, and make each
124 class in C<@class_names> immutable in between the two runs.
132 =item Convert the Moose test suite to use this module.
134 =item Here is a list of possible functions to write
138 =item immutability predicates
140 =item anon-class predicates
142 =item discovering original method from modified method
144 =item attribute metaclass predicates (attribute_isa?)
