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).
