You want to unit test a rule to ensure that the rule executes as intended,...

To populate a test page with valid data before testing the rule, you can run a data transform to create the test page or copy data from an existing clipboard page. A data transform is a rule that defines how to convert data that is in one format and class (the source) into data of another format and class (the target). The clipboard is a temporary memory area on the server that stores property values for your application.
