The goal of this exercise is to extend base method content associated with a role using Extends and Replaces variability.
In the Configuration view you will see that there is no tester role in the Basic Roles folder. It was replaced by the My Extend and Replace Tester role.
Also notice that other content elements in the base plug-in that referenced the tester role now reference the extend and replacing role instead. If you open the Disciplines folder and view the task Implement Test, you will see that the Primary Performer is now My Extend and Replace Tester. Extends and Replaces works in a similar way for tasks, artifacts, guidance and categories.
