Testing allows you to check out your settings before they are activated. Clicking on the “Test” button will automatically show what the recommendation results will look like.
The “Property” box is designed for users who would like to customize the testing for particular items and users. Typing in Item IDs and User IDs will set the context for the logic, and the test will show you what the action will recommend to a given user or on a given product page. The “Property Browser” button allows the user to easily search items and users.
