仅在 Intellij 调试器中检测到 Mockito 未完成的存根异常 [英] Mockito unfinished stubbing exception detected ONLY in Intellij Debugger
问题描述
仅当我尝试通过 IntelliJ 调试器调试测试时才会出现此问题.当我只是简单地运行测试时，它不会发生.
The problem only occurs when I am trying to debug a test via the IntelliJ debugger. It does not happen when I just simply run the test.
CustomerChoiceRepository 是一个普通的 Spring Boot JPA 存储库，这里使用 @Mock 进行模拟.
CustomerChoiceRepository is a normal Spring Boot JPA repository which here is being mocked with @Mock.
当此行在调试器中执行时，我在变量的监视部分收到以下错误:
When this line executes in the debugger I get the following error in the watch section of the variables:
整个错误信息是:
Method threw 'org.mockito.exceptions.misusing.UnfinishedStubbingException' exception. Cannot evaluate com.item.repository.jpa.CustomerChoiceRepository$MockitoMock$1318657964.toString()
这只是在 IntelliJ 调试器中检测到的，因此测试失败只有在我调试它时.
Again this is only is detected in the IntelliJ debugger, as a result the test fails only when I am debugging it.
所以我的问题是:这里发生了什么?
So my question is: what is happening here?
这是一个错误吗?这是因为我对 Mockito 的内部结构不是特别了解而无法理解的吗?
Is this a bug ? Is this something that I fail to understand because I do not know the internals of Mockito particularly well ?
推荐答案
你的 IntelliJ 在 stubbing 期间在 mock 上调用 toString，导致异常.
Your IntelliJ is calling toString on the mock during stubbing, which causes the exception.
检查您的调试器设置
默认情况下，IntelliJ 在调试器窗口中的对象上调用 toString，但仅在覆盖该方法的对象上调用.此行为是可自定义的，目前在 Preferences ->;构建工具->调试器->数据视图 ->爪哇->启用 'toString' 对象视图，但 IDE 版本之间的设置可能有所不同.
By default, IntelliJ calls toString on objects in debugger window, but only on objects that override that method. This behaviour is customizable, currently in Preferences -> Build Tools -> Debugger -> Data Views -> Java -> Enable 'toString' object view, but the settings mey differ between IDE versions.

在存根期间不要调用模拟对象的方法
