If I only had seven test cases before a release I would input seven different numbers in the program. Since the program is only supposed to take in whole numbers, the first test can be inputting a whole number from 1 to 8. Next, a whole number greater than 8 can be used. The number and a negative number are two more test cases. The fourth test case is a blank. The fifth is using a number that is not a whole number between 1 and 8. The sixth and seventh are non-whole numbers greater than 8 and less than 1, respectively. This seven test cases will test how robust the program was built.
