The current tests do not cover this file. Therefore, you have two options to complete the last part of P1B:

(a) Write tests from scratch to cover that file OR
(b) Select another file currently covered by tests (under src/) that is NOT fully covered and do the following:

• Increase the coverage of the file by at least one line.
• Commit your changes to the same branch referenced in the PR.
• For the final part of the task (manual testing), activate at least one function of the file you selected from the user interface (UI).
