当我运行mockito测试时发生WrongTypeOfReturnValue Exception [英] when I run mockito test occurs WrongTypeOfReturnValue Exception

问题描述

错误详细信息：

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);

如你所见，我在 > updateItemAttributes （确实返回 boolean ）不在 updateItemAttributesByJuId 。

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

1. 为什么Mockito试图从返回布尔 updateItemAttributesByJuId ？


2. 如何纠正？

1. Why is Mockito attempting to return a boolean from updateItemAttributesByJuId?
2. How can this be rectified?

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()
