Quiz 2.5: Assignments with sub-questions

Testing FizzBuzz

Given this class:

public class FizzBuzz {
    public String fizzbuzzer(int n) {
        if (n % 15 == 0) return "FizzBuzz";
        if (n % 3 == 0) return "Fizz";
        if (n % 5 == 0) return "Buzz";
        return String.valueOf(n);
    }
}

Subquestion 1a (2 points)

Which test is useful and working?

1. A test that asserts "Fizz" for input 9:

   @Test
   void nineGivesFizz() {
       assertEquals("Fizz", fizzBuzz.fizzbuzzer(9));
   }

2. A test that only checks that the result is not null:

   @Test
   void givesSomething() {
       assertNotNull(fizzBuzz.fizzbuzzer(1));
   }
