Java Mockito org.Mockito.exceptions.misusing.unfinishedstubingexception:检测到未完成的存根

我想使用mockito和powermockito为下一个spring MVC控制器编写单元测试用例

@Controller
@Configuration
@PropertySource("classpath:project/web/properties/RealTimeAPI.properties")
@RequestMapping("/learnon")
public class ClassManagerController {

    private final Logger logger = Logger.getLogger(ClassManagerController.class);
    @Autowired
    private ClassManagerService classManagerService;

    @Autowired
    private GroupUserService groupUserService;

    @RequestMapping(value = "/teacher", method = RequestMethod.GET)
    public ModelAndView showClassDetail(HttpServletRequest request, HttpSession httpSession,
                                        @RequestParam(value = "isbn", required = false) String isbn13,
                                        @RequestParam(value = "classId", required = false) Long classId) {

        String redirectUrl = "https://example.com/jsp/Login.jsp?reason=failedLogin&redirectUri=https://example.com/secure/Bookshelf";
        String accessDeniedUri = "https://example.com/jsp/AccessDenied.jsp";

        if (httpSession.getAttribute("USERID") == null) {
            return new ModelAndView("redirect:" + redirectUrl);
        }
        try {
            long userId = Long.parseLong(httpSession.getAttribute("USERID").toString());
            UserBean user = classManagerService.getUser(userId);
            if (httpSession.getAttribute("SCHOOLID") == null) {

            }
            String isbn10 = ISBNUtil.convertIsbn13ToIsbn10(isbn13);
            String title = "";

            ModelAndView mav = null;
            ClassManagerBean classBean = null;

            if(classId == null && httpSession.getAttribute("classId") != null){
                classId = (Long)httpSession.getAttribute("classId");
            }

            if(classId != null && classId > 0) {
                List<UserBean> userBeanList = classManagerService.getUserList(user.getSchoolId(), classId, isbn10);
                classBean = classManagerService.getClassById(classId);
                classBean.setUserNumber(userBeanList.size());
                title = classBean.getTitle();
                //Set the view to ClassManager.jsp
                mav = new ModelAndView("ClassManager");
                mav.addObject("userList", userBeanList);
                boolean authorized = userBeanList.stream().anyMatch(u->u.getUserId() == userId);

            return mav2;
        }
    }

}

我试图解决这个异常，但仍然没有成功。请帮助我解决此异常

编辑：

我删除了下面的一行 doReturn（false）.when（spyList.stream（）.anyMatch（u->u.getUserId（）==Mockito.anyLong（））

并更新测试，如下所示

@Test
    public void testShowClassDetail1() throws Exception {


        HttpServletRequest httpRequest = mock(HttpServletRequest.class);
        HttpSession httpSession = mock(HttpSession.class);

        Mockito.when(httpSession.getAttribute("USERID")).thenReturn(1l);

        UserBean beanMock = mock(UserBean.class);

        Mockito.when(classManagerService.getUser(1l)).thenReturn(beanMock);

        List<UserBean> beanList = new ArrayList<>(); 
        beanList.add(beanMock); 


        Mockito.when(classManagerService.getUserList(Mockito.anyLong(), Mockito.anyLong(), Mockito.anyString())).thenReturn(beanList);

        Mockito.when(beanMock.getUserId()).thenReturn(2l);


        RequestBuilder request = MockMvcRequestBuilders
                .get("/learnon/teacher")
                .param("isbn", "1234567890123")
                .param("classId", "1")  
                .accept(MediaType.APPLICATION_JSON);


        String modalView = "redirect:" + "https://example.com/jsp/AccessDenied.jsp";

        ResultActions result = mockMvc.perform(request)
                .andExpect(status().is3xxRedirection())
                .andExpect(view().name(modalView));

       }

@测试
public void testShowClassDetail1（）引发异常{
HttpServletRequest httpRequest=mock（HttpServletRequest.class）；
HttpSession-HttpSession=mock（HttpSession.class）；
Mockito.when（httpSession.getAttribute（“USERID”））。然后返回（1l）；
UserBean beanMock=mock（UserBean.class）；
Mockito.when（classManagerService.getUser（1l））.thenReturn（beanMock）；
List beanList=new ArrayList（）；
添加（beanMock）；
Mockito.when（classManagerService.getUserList（Mockito.anyLong（），Mockito.anyLong（），Mockito.anyString（））。然后返回（beanList）；
Mockito.when（beanMock.getUserId（））.thenReturn（2l）；
RequestBuilder request=MockMvcRequestBuilders
.get（“/learnon/teacher”）
.param（“isbn”、“1234567890123”）
.param（“classId”、“1”）
.accept（MediaType.APPLICATION_JSON）；
字符串modalView=“重定向：+”https://example.com/jsp/AccessDenied.jsp";
ResultActions result=mockMvc.perform（请求）
.andExpect（状态（）.is3xx重定向（））
.andExpect（view（）.name（modalView））；
}

现在，我得到以下AssetionError

java.lang.AssertionError:视图名称 预期：https://example.com/jsp/AccessDenied.jsp>但是 是：https://example.com/jsp/Login.jsp?reason=failedLogin&redirectUri=https:/

---

让我们看一下下面这行（为便于阅读而格式化）：

它包含两个错误，一个由异常报告，但我也将解释另一个

错误1：当 为了记录方法调用，必须将模拟的方法调用结果传递给when函数。代码中不是这样，因为

stream（）

返回真实对象

看

错误2：ArgumentMatchers的使用无效 不能将

Mockito.anyLong（）

用作任意值。这会编译，因为ArgumentMatcher返回伪值（零），但不会按预期工作（与anyLong（）的比较并不总是真的）

看

解决方案 模拟的目标是强制测试方法满足某些条件。 您的目标是在按id查找用户时返回false。 要实现它，只需使用空列表。这意味着可以删除整个有问题的行。

你能指出导致错误的那一行吗？我删除了错误行并更新了测试。但是我现在得到了断言错误。你能看看问题的编辑吗。让我知道测试失败的原因如果你需要你的

布尔授权

在测试中为真，您需要有一个UserBean，其userId等于您在会话中提供的userId（在测试中为1L）。只需将这样一个userBean添加到测试中创建的

列表中即可（如果创建userBean有困难，请添加一个带有
getUserId
返回1L的模拟）。谢谢@Lesiak。我更新了测试并添加了一个答案，看起来不错。我建议：1。重命名变量（
beanMock
->
userMock
，
beanList
->
userList
等）。2.提取神奇常量：
long userId=1L
。3.不清楚为什么
Mockito.when（beanMock.getUserId（））.thenReturn（2l）返回2L，而不是1L（同样，神奇常数）
