+=head1 DESCRIPTION
+
+This module provides some useful test functions for Mouse 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 I<CODE> *which should contain normal tests) twice, and make each
+class in I<@class_names> immutable between the two runs.
