Java org.mockito.exceptions.misusing.invalidUseofMatcherException

我有这个测试

@Test
public void addVacancy() throws Exception{

        Vacancy mockVacancy = Mockito.mock(Vacancy.class);
        BindingResult mockResult= Mockito.mock(BindingResult.class);
        RedirectAttributes mockRedirectAttributes=Mockito.mock(RedirectAttributes.class);
        Model mockModel = Mockito.mock(Model.class);

        ModelAndView modelAndView;

        when(mockResult.hasErrors()).thenReturn(false);

        VacancyService vacancyService = Mockito.mock(VacancyService.class);
        vacancyMenuController.vacancyService = vacancyService;

        modelAndView = vacancyMenuController.addVacancy(mockVacancy, mockResult, mockModel, mockRedirectAttributes); 
        Mockito.verify(vacancyService, Mockito.times(1)).add(Mockito.any(Vacancy.class));//good work
        Mockito.verify(mockRedirectAttributes,Mockito.times(1)).addAttribute("message",anyString());// exception
    }

Mockito.verify(mockRedirectAttributes,Mockito.times(1)).addAttribute("message",anyString());// exception

对于此方法：

@RequestMapping("/addVacancy")
    public ModelAndView addVacancy(@ModelAttribute("myVacancy") @Valid Vacancy vacancy,BindingResult result, Model model,RedirectAttributes redirectAttributes){
        if(result.hasErrors()){
            model.addAttribute("message","validation error");
            return new ModelAndView("vacancyDetailsAdd");
        }
        vacancyService.add(vacancy);
        ModelAndView mv = new ModelAndView("redirect:goToVacancyDetails");
        mv.addObject("idVacancy", vacancy.getId());
        redirectAttributes.addAttribute("message", "added correctly at "+ new Date());
        return mv;
    }

Mockito.verify(mockRedirectAttributes,Mockito.times(1)).addAttribute("message",anyString());// exception

为什么该字符串工作良好：

Mockito.verify(vacancyService, Mockito.times(1)).add(Mockito.any(Vacancy.class));//good work

Mockito.verify(mockRedirectAttributes,Mockito.times(1)).addAttribute("message",anyString());// exception

但在这里我看到了例外

Mockito.verify(mockRedirectAttributes,Mockito.times(1)).addAttribute("message",anyString());// exception

完整跟踪：

Mockito.verify(mockRedirectAttributes,Mockito.times(1)).addAttribute("message",anyString());// exception

org.mockito.exceptions.misusing.InvalidUseOfMatchersException: 
Invalid use of argument matchers!
2 matchers expected, 1 recorded:
-> at com.epam.hhsystem.web.controllers.VacancyMenuControllerTest.addVacancy(VacancyMenuControllerTest.java:186)

This exception may occur if matchers are combined with raw values:
    //incorrect:
    someMethod(anyObject(), "raw String");
When using matchers, all arguments have to be provided by matchers.
For example:
    //correct:
    someMethod(anyObject(), eq("String by matcher"));

For more info see javadoc for Matchers class.

您的

addAttribute（）

验证需要在字符串“message”周围有

eq（）

。 使用其中一个匹配器时，必须对方法中的所有参数使用它

Mockito.verify(mockRedirectAttributes,Mockito.times(1)).addAttribute("message",anyString());// exception

Mockito.verify(mockRedirectAttributes,Mockito.times(1)).addAttribute(eq("message"),anyString());

---

请参阅添加的

eq

Mockito.eq（仅适用于5月份的情况）。您可以检查此字符串是否为invoke ModelAndView mv=new ModelAndView（“重定向：goToVacancyDetails”）？

Mockito.verify(mockRedirectAttributes,Mockito.times(1)).addAttribute("message",anyString());// exception
