java - Change the comportement of one method inside a class using Mockito

Question

I'm learning Mockito and I currently have a problem (I'm sorry for my english level ...) I have this class :

public class MySuperClass {
     int x;
     int y;

     MySuperClass(int x, int y) { this.x = x; this.y = y)

     int mehtod1() {
         int b = x + method2(y);
         return b;
     }

     int method2() {
         return x + y;
     }
}

And now, I would like to return 0 when I call the method2(). I have this test but this test isn't concluent ...

MySuperClass mockSuperClass = Mockito.spy(new mockSuperClass(5, 6));

Mockito.when(mockSuperClass.method2()).thenReturn(0));

assertEquals(5, mockSuperClass.method1());

I think this question is very basic but I don't find the solution ... Thanks your very much !

NB : Mockito 3.6 ; Junit 5.7
