The test code changes the color of the LED based on the potentiometer position. In addition, the buzzer turns on and off at a specific potentiometer position. The compiled test code can be found in lab8_test.out. If you want to look at it, the underlying code can be found in this CCS project, which you’ll need to import as usual: lab8_test.zip.
