You can publish the Player to Knowledge Center with Test It! mode included. When you launch the Player through Knowledge Center, you can play Test It! mode. All of the play modes, including Test It! are tracked, and the results are included in the Test It! Summary report.
When a Player with Test It! mode is published to or imported into Knowledge Center, [Test] is appended to the title. This is to differentiate it from a regular Player for learning purposes.
