Mockito를 사용하여 슈퍼클래스의 메서드 호출을 모의하는 방법: 실용 가이드

<code class="java">class BaseService {  
    public void save() {...}  
}

public Childservice extends BaseService {  
    public void save(){  
        //some code  
        super.save();
    }  
}   </code>

<code class="java">class BaseService {

    public void validate(){
        fail(" I must not be called");
    }

    public void save(){
        //Save method of super will still be called.
        validate();
    }
}

class ChildService extends BaseService{

    public void load(){}

    public void save(){
        super.save();
        load();
    }
}

@Test
public void testSave() {
    ChildService classToTest = Mockito.spy(new ChildService());

    // Prevent/stub logic in super.save()
    Mockito.doNothing().when((BaseService)classToTest).validate();

    // When
    classToTest.save();

    // Then
    verify(classToTest).load();
}</code>
