Question

Write Junit test for the following class below:

public class Player {

  
   public int turnScore;
   public int roundScore;
   public int lastTurnScore;
   public String name;
   public int chipPile;
  

   public Player (String name) {
       this.name = name;
       this.turnScore = 0;
       this.chipPile = 50;
   }
  
  
   public int getChip() {
       return chipPile;
   }
  
   public void addChip(int chips) {
       chipPile += chips;
   }

  
   public int getRoundScore() {
       return roundScore;
   }
  
   public void setRoundScore(int points) {
       roundScore += points;
   }
  
   public int getTurnScore() {
       return turnScore;
   }

   public void setTurnScore(int turnScore) {
       this.turnScore = turnScore;
   }
  
   public boolean checkHundred () {
       if (getTurnScore() >= 100) {
           return true;
       }
       return false;
   }
}

Answer 1

I changed addChips method slightly to check if chips are not negative

public void addChip(int chips) {
   if(chips < 0) throw new IllegalArgumentException();
   else
chipPile += chips;
}

import static org.junit.Assert.*;

import org.junit.Assert;
import org.junit.Test;

public class PlayerTest {

  

   @Test
   public void testGetChip() {
       Player player = new Player("Jon");
       player.addChip(50);
       System.out.println(player.getChip());
       Assert.assertEquals(100, player.getChip());
      
   }

   @Test
   public void testAddChip() {
       Player player = new Player("Jon");
       player.addChip(10);
//       System.out.println(player.getChip());
       Assert.assertEquals(60, player.getChip());
   }
   @Test(expected = IllegalArgumentException.class)
public void testAddChipNegativeValue(){
       Player player = new Player("Jon");
       player.addChip(-10);
}
   @Test
   public void testGetRoundScore() {
       Player player = new Player("Jon");
       player.setRoundScore(50);
       Assert.assertEquals(50, player.getRoundScore());
   }

   @Test
   public void testSetRoundScore() {
       Player player = new Player("Jon");
       player.setRoundScore(10);
       Assert.assertEquals(10, player.getRoundScore());
   }

   @Test
   public void testGetTurnScore() {
       Player player = new Player("Jon");
       player.setTurnScore(10);
       Assert.assertEquals(10, player.getTurnScore());
   }

   @Test
   public void testSetTurnScore() {
       Player player = new Player("Jon");
       player.setTurnScore(10);
       Assert.assertEquals(10, player.getTurnScore());
   }

   @Test
   public void testCheckHundred() {
       Player player = new Player("Jon");
       player.setTurnScore(10);
       Assert.assertEquals(false, player.checkHundred());
       Player player1 = new Player("Jon1");
       player.setTurnScore(110);
       System.out.println("**"+player1.checkHundred() +" "+player1.getTurnScore());
       Assert.assertEquals(false, player1.checkHundred());

   }
