junit模拟错误:org.mockito.exceptions.misusing.missingmethodinvoc

Question

我正在使用spring data JPA来创建服务，并且用于单元测试，我正在使用Junit和mockito。在以下代码中，我试图为服务类进行JUNIT测试。

房间帐户映射服务类取决于房间调查员映射服务类，因此我使用Mockito进行模拟房间调查员映射服务类方法，但是该方法调用了同一类的另一种方法。

我尝试过下面的尝试，但在Mockito中遇到了错误。有人可以告诉我如何嘲笑吗？

TestRoomAccountMappingservice类

public class TestRoomAccountMappingService {
    @MockBean
    RoomAccountMappingRepository roomAccountMapRepository;
    @Autowired
    RoomAccountMappingService roomAccountMappingService;
    @Autowired
    RoomInvestigatorMappingService roomInvestMapService;
    @Test
    public void deleteAccountMapping() {
        Integer[] RoomAllocationId= {1839};         
        //here getting error
        Mockito.when(roomInvestMapService.returnRoomWithinClusterByRoomAllocationID(1839)).thenReturn(RoomAllocationId);
        RoomAccountMapping roomAcctMap= new RoomAccountMapping();
        roomAcctMap.setnRoomAllocationId(1);
        List<RoomAccountMapping> roomList= new ArrayList<>();
        roomList.add(roomAcctMap);      
        Mockito.when(roomAccountMapRepository.findByNRoomAllocationId(1839)).thenReturn(roomList);
        Boolean actual = roomAccountMappingService.deleteAccountMapping(1839);
        assertEquals(true, actual );
    }
}

失败跟踪

org.mockito.exceptions.misusing.MissingMethodInvocationException: 
when() requires an argument which has to be 'a method call on a mock'.
For example:
    when(mock.getArticles()).thenReturn(articles);
Also, this error might show up because:
1. you stub either of: final/private/equals()/hashCode() methods.
   Those methods *cannot* be stubbed/verified.
   Mocking methods declared on non-public parent classes is not supported.
2. inside when() you don't call method on mock but on some other object.

Answer 1

正如错误消息告诉您...

2. 内部（）（）您不在模拟上调用方法，而在其他某些对象上调用方法。

这里可能是这种情况：

Mockito.when(roomInvestMapService.returnRoomWithinClusterByRoomAllocationID(1839))...

...因为：

@Autowired
RoomInvestigatorMappingService roomInvestMapService;

...可能不是模拟，因为您不使用@MockBean。至少对我而言，目前似乎是最合理的解释。
