Question

Add two more statements to main() to test inputs 3 and -1. Use print statements similar to the existing one (don't use assert).

...

import java.util.Scanner;

public class UnitTesting {
   // Method returns origNum cubed
   public static int cubeNum(int origNum) {
      return origNum * origNum * origNum;
   }

   public static void main (String [] args) {

      System.out.println("Testing started");
      System.out.println("2, expecting 8, got: " + cubeNum(2));

      /* Your solution goes here */

      System.out.println("Testing completed");
   }
}

Answer 1

public class UnitTesting {
    public int cubeNum(int origNum) {
        return origNum * origNum * origNum;
    }

    public static void main(String[] args) {
        UnitTesting cubeTester = new UnitTesting();
        System.out.println("Testing started");
        System.out.println("2, expecting 8, got: " + cubeTester.cubeNum(2));

        System.out.println("3, expecting 27, got: " + cubeTester.cubeNum(3));
        System.out.println("-1, expecting -1, got: " + cubeTester.cubeNum(-1));

        System.out.println("Testing completed");
    }
}
