@RunWith(MockitoJUnitRunner.class)

    @Mock
    private MapperFacade mapperFacade;

    @InjectMocks
    private MyService myService;

    // 测试方法...
}

@Test
public void testSomeMethod() {
    // 创建一个模拟的返回值
    SomeDTO expectedDTO = new SomeDTO();
    expectedDTO.setId(1);
    expectedDTO.setName("Mocked DTO");

    // 使用when方法模拟MapperFacade的返回值
    when(mapperFacade.map(any(SomeEntity.class), eq(SomeDTO.class))).thenReturn(expectedDTO);

    // 调用被测试的方法
    SomeDTO result = myService.someMethod(new SomeEntity());

    // 断言结果是否符合预期
    assertEquals(expectedDTO, result);
}
