Question

I need help to write a test case.

1. Go to the ConcertTicketTest.java file and write test cases for the compareTo method you just implemented.

/* ConcertTicket.java file */

package SearchingSorting;

/**
*
* @author clatulip
*/
public class ConcertTicket implements Comparable<ConcertTicket> {

private String name;
private int price;
private char row;
private int seat;

public ConcertTicket(String name, int price) {
this.name = name;
this.price = price;
// randomly create a row and seat
// assumes 60 seats across width of venue
// seat 1 at far left
seat = (int)(Math.random()*60 + 1);
// assume 26 rows from front to back
// row A at front
row = (char)((int)(Math.random()*26) + 65); // 065 is ASCII code for 'A'
}

public ConcertTicket() {
name = "";
price = 0;
}

public String getName() {
return name;
}

public int getPrice() {
return price;
}

public char getRow() {
return row;
}

public int getSeat() {
return seat;
}

@Override
public String toString() {
return "ConcertTicket{" + "\t price=" + price + "\t row=" + row + "\t seat= " + seat + "\t name=" + name +'}';
}
  
@Override
public int compareTo(ConcertTicket o) {
  
  
if(this.price == o.price){
return 0;
}
else if(this.price < o.price){
return -1;
}

if(this.price > o.price){
return 1;
}
  
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}

}

public class ConcertTicketTest {

ConcertTicket ct2;
ConcertTicket ct3;
ConcertTicket ct4;
  
public ConcertTicketTest() {
ct1 = new ConcertTicket("Niche Artist", 5);
ct2 = new ConcertTicket("Popular Artist", 6);
ct3 = new ConcertTicket("International Superstar", 7);
ct4 = new ConcertTicket("Pop Star", 7);
}

/**
* Test of compareTo method, of class ConcertTicket.
*/
@Test
public void testCompareTo() {
System.out.println("compareTo");
  

//TODO: Test the compareTo method for the ConcertTicket class
throw new UnsupportedOperationException("Not supported yet");
}
  
}

Answer 1

The completed code is given below.
Please do rate the answer if it helped. Thank you.

/* ConcertTicketTest.java */

package SearchingSorting;
import SearchingSorting.ConcertTicket;
import org.junit.Test;
import static org.junit.Assert.*;

/**
*
* @author Kyle
*/
public class ConcertTicketTest {

   ConcertTicket ct1;
   ConcertTicket ct2;
   ConcertTicket ct3;
   ConcertTicket ct4;

   public ConcertTicketTest() {
       ct1 = new ConcertTicket("Niche Artist", 5);
       ct2 = new ConcertTicket("Popular Artist", 6);
       ct3 = new ConcertTicket("International Superstar", 7);
       ct4 = new ConcertTicket("Pop Star", 7);
   }

   /**
   * Test of compareTo method, of class ConcertTicket.
   */
   @Test
   public void testCompareTo() {
       System.out.println("compareTo");
       assertEquals(ct1.compareTo(ct2), -1);
       assertEquals(ct3.compareTo(ct2), 1);
       assertEquals(ct3.compareTo(ct3), 0);
   }

}
