当我运行 mockito 测试时发生 WrongTypeOfReturnValue 异常

2022-01-14 00:00:00 mockito java

错误详情:

org.mockito.exceptions.misusing.WrongTypeOfReturnValue: 
Boolean cannot be returned by updateItemAttributesByJuId()
updateItemAttributesByJuId() should return ResultRich
This exception might occur in wrongly written multi-threaded tests.
Please refer to Mockito FAQ on limitations of concurrency testing.

我的代码:

@InjectMocks
protected ItemArrangeManager arrangeManagerSpy = spy(new ItemArrangeManagerImpl());
@Mock
protected JuItemWriteService juItemWriteService;

when(arrangeManagerSpy
    .updateItemAttributes(mapCaptor.capture(), eq(juId), eq(itemTO.getSellerId())))
    .thenReturn(false);

如您所见，我在 updateItemAttributes 上调用 when(它确实返回 boolean)而不是在 updateItemAttributesByJuId.

As you can see, I am calling when on updateItemAttributes (which does return a boolean) not on updateItemAttributesByJuId.

  1. 为什么 Mockito 试图从 updateItemAttributesByJuId 返回一个 boolean?
  2. 如何改正?

推荐答案

根据https:///groups.google.com/forum/?fromgroups#!topic/mockito/9WUvkhZUy90，你应该改写你的

when(bar.getFoo()).thenReturn(fooBar)

到

doReturn(fooBar).when(bar).getFoo()
