Question

Create Junit tests for the following classes

public class Dice

{
   private Die die1;
   private Die die2;

   public Dice()
   {
       this.die1 = new Die();
       this.die2 = new Die();
   }

   public Dice(int[] programmedRolls)
   {
       int[] programmableroll = programmedRolls;
       this.die1 = new Die(programmableroll);
       this.die1 = new Die(programmableroll);
      
   }
  
   public Dice(Die die1, Die die2)
   {
       this.die1 = die1;
       this.die2 = die2;
   }
  
   public void roll() {
       die1.roll();
       die2.roll();
   }
  
   public int getDie1Value() {
       return die1.getLastRoll();
   }

  
   public int getDie2Value() {
       return die2.getLastRoll();
   }

  
   public int getDiceValue()
   {
       return die1.getLastRoll() + die2.getLastRoll();
   }

   public int getLastRoll() {
       return die1.getLastRoll() + die2.getLastRoll();
   }  
}

public class SkunkDice extends Dice{

   public SkunkDice() {
      
   }
  

   public boolean isSkunk()
   {
       return (getDie1Value() == 1 || getDie2Value() == 1 && getDiceValue() != 2);
   }

   public boolean isDoubleSkunk() {
       return (getDiceValue() == 2);
   }
  
}
