Question

我希望A类中继承的getter返回Mock of MyObject。如果不直接在A中使用getMyObject（）方法（即通过使用一些MockBase类），我怎么能这样做呢？

     public class Base {
         @Autowired
         private MyObject obj;
         public MyObject getMyObject(){
            return obj;
         }
     }


    public class A extends Base {
     @Autowired
     private SomeObject xyz; 

     public void myMethod(){
       MyObject  obj = getMyObject();
       //do something here
      }

    }

  public void MockBase {
      @Mock
      protected MyObject obj;

      public MyObject getMyObject(){
            return obj;
      }
  }

  public class ATest extends MockBase  {
    @InjectMocks
    private A a;

    @Mock
    private SomeObject xyz;


    @BeforeMethod
    public void setUp(){
        MockitoAnnotations.initMocks(this);
    } 

    public void MyMethod_SomeCondition_ExpectedResult{
       a.myMethod();
    }
   }

那里有什么问题？它按预期工作，也许你使用旧版Mockito。例如，版本1.9.5：

Heres是您要测试的班级的父级：

public class Base {
    private BaseObjectDependency base_object_dependency;

    public BaseObjectDependency getBase_object_dependency() {
        return base_object_dependency;
    }
}

以下是您要测试的课程：

public class Child extends Base {
    private ChildObjectDependency child_object_dependency;

    public void myMethod() {
        BaseObjectDependency obj = getBase_object_dependency();
        //do something here
    }

    public ChildObjectDependency getChild_object_dependency() {
        return child_object_dependency;
    }
}

以下是依赖项：

public class BaseObjectDependency { }

public class ChildObjectDependency { }

现在这里是测试的父类：

import org.mockito.Mock;

public class MockBase {
    @Mock protected BaseObjectDependency base_test_dependency_mock;
}

最后测试：

import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.MockitoAnnotations;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;

import static org.testng.Assert.assertEquals;
import static org.testng.Assert.assertNotNull;

public class ChildTest extends MockBase {
    @InjectMocks private Child child;

    @Mock private ChildObjectDependency child_test_dependency_mock;


    @BeforeClass
    public void setUp() {
        MockitoAnnotations.initMocks(this);
    }

    @Test
    public void check_that_mocks_are_correctly_injected() {
        assertNotNull(child.getBase_object_dependency());
        assertEquals(base_test_dependency_mock, child.getBase_object_dependency());

        assertNotNull(child.getChild_object_dependency());
        assertEquals(child_test_dependency_mock, child.getChild_object_dependency());
    }
}

你会发现我无处可去getBase_object_dependency()。

使继承的getter返回mock对象
