Question

You only need to use Junit to test 3 methods of the Nurse class.

public Nurse(int a, float s) { ... }

public boolean isBusy() {...}

public void retire() {....}

code:

public class Nurse {
   private int numOfPatients;
   private float salary;

   // Helping function
   // private void trace(char* s) { cout << s << endl; }

   // Implementor function
   public Nurse(int a, float s) { numOfPatients =a; salary=s; }

   // Access function
   public int getNumOfPatients() { return numOfPatients; }
   public float getSalary() {  return salary; }
   public void  setNumOfPatients(int a) {   numOfPatients=a; }
   public void  setSalary(float s) {   salary=s; }
   public boolean isBusy() {
         // trace("predicate");
         return numOfPatients > 30;
   }

   // Implentor function
   public void retire() {
      // trace("implementor");
      numOfPatients=0
      salary=0;
   }
   public void payRaise(float raise) {
      // trace("implementor");
      salary += raise;
   }

   public static void main(String atgv[])
   {
      Nurse mary= new Nurse(25, 80000);
      if (mary.isBusy())
         System.out.println("Mary is busy");
      else
         System.out.println("Mary is not busy");
      mary.payRaise(3000);
      System.out.println("Mary's salary is " + mary.getSalary());
      mary.retire();
      System.out.println("Mary has " 
             + mary.getNumOfPatients() 
             + " of patients after she retired.");
   }
}

import org.junit.Test;
import static org.junit.Assert.assertEquals;
public class Testlogic {
public void   testEquals(){
       final int value = 25;
   final float value1 = 80000;

   Nurse mary = new Nurse(value,value1);   
   assertEquals(4,Nurse(value,value1);
   assertEquals(-1,Nurse(value,value1);
   }
   public void isBusy(){
   assertEquals(4,Nurse.isBusy());
   assertEquals(-1,Nurse.isBusy());
   }
   public void retire(){
   assertEquals(4,Nurse.retire());
   assertEquals(-1,Nurse.retire());
   }
}
