mockito example setter
I was writing below example
https://www.youtube.com/watch?v=ShO_Z64sGwI&list=PLZM-6wiKGRfGmXzuR8uX3UsE8g91K6Vp1&index=5
package com.gp.mockito;
import org.junit.Before;
import org.junit.Test;
import junit.framework.Assert;
import static org.mockito.Mockito.*;
public class CalculatorServiceTest {
CalculatorService calService;
@Before
public void setup(){
ICalculator cal_mock = mock(ICalculator.class);
when(cal_mock.add(2, 4)).thenReturn(6);
calService=new CalculatorService();
//calService.setCal(cal_mock);
}
@Test
public void testAddNumbers(){
Assert.assertEquals(6, calService.addTwoNumbers(2,4));
}
}
package com.gp.mockito;
public class CalculatorService {
ICalculator cal;
public ICalculator getCal() {
return cal;
}
public void setCal(ICalculator cal) {
this.cal = cal;
}
public int addTwoNumbers(int x, int y){
return cal.add(x, y);
}
}
package com.gp.mockito;
public interface ICalculator {
public int add(int x,int y);
}
why are they setting interface mock object to the calservice object
observerd one example here

Start your 7-day free trialIf you mock the dependency you need to tell the class under test to make use of the mocked dependency and not the real one. One way of doing it is via a setter method or a constructor or just use dependency injectionif i implement that interface in the class then there is no need of this setter here?
package com.gp.mockito;
public class CalculatorService implements ICalculator {
and then implements interface method here
public int add(int x, int y) {
// TODO Auto-generated method stub
return 0;
}

The ICalculator is a dependency of this class.
