如何在静态方法上使用 Mockito.verify()？

Question

我正在研究 Junit 和 Mockito。在我的项目中，我有一个 SocialDataAccess 控制器，其代码如下所示：

public class SocialDataAccessController implements Controller{

private SocialAuthServiceProvider socialAuthServiceProvider;

@Override
    public ModelAndView handleRequest(HttpServletRequest request,
            HttpServletResponse response) throws Exception {
        String provider = request.getParameter("pId");
        String appCode =  request.getParameter("apc");

         * check if data in session is of the same provider orof different
         * provider, if different then remove auth and request token
         **/

        SocialUtility.removeOtherProviderAuthTokenFromSession(request,provider);

        try {
            /** creating the OAuthService object based on provider type **/
            OAuthService service = getSocialAuthServiceProvider().getOAuthServiceProvider(appCode, provider);
            .....
            ........
            ............            
return new ModelAndView("redirect:callback.html?pId=" + provider);
    }

public SocialAuthServiceProvider getSocialAuthServiceProvider() {
        return socialAuthServiceProvider;
    }

}

这就是我所做的。我提出了一个请求，我的请求成功调用了我的控制器。当我尝试使用Mockito.verify() 来测试我的静态方法是否被调用时，出现如下所示的错误。

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(
        locations={
            "file:/opt/div/BatchWorkspace/harvest_branch/WebContent/WEB-INF/test-servlet.xml"
        }
)

public class TestSocialDataAccessController {   
    @Autowired
    private WebApplicationContext wac;

    private MockMvc mockMvc;

    @Before
    public void setUp() {
        mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();      
    }


    @SuppressWarnings("static-access")
    @Test
    public void testBasicSetUp() throws Exception{
        RequestBuilder requestBuilder = MockMvcRequestBuilders.get("/social-connect.html")
                .param("apc","tj")
                .param("src","google")
                .param("pId","ggl")
                .param("cl","xxxxxxxxxxxxxx");

        mockMvc.perform(requestBuilder)
       .andDo(MockMvcResultHandlers.print())
       .andExpect(MockMvcResultMatchers.status().isMovedTemporarily())
       .andExpect(MockMvcResultMatchers.redirectedUrl("xxxxxxxx"));

           SocialUtility sutil = new SocialUtility();
           SocialUtility spy = Mockito.spy(sutil);
           MockHttpServletRequest request = requestBuilder.buildRequest(wac.getServletContext());
           Mockito.verify(spy).removeOtherProviderAuthTokenFromSession(request,Matchers.anyString());          

    }
}

我得到的错误：

org.mockito.exceptions.misusing.UnfinishedVerificationException: 
Missing method call for verify(mock) here:
-> at com.tj.harvest.testcase.TestSocialDataAccessController.testBasicSetUp(TestSocialDataAccessController.java:88)

Example of correct verification:
    verify(mock).doSomething()

Also, this error might show up because you verify either of: final/private/equals()/hashCode() methods.
Those methods *cannot* be stubbed/verified.
Mocking methods declared on non-public parent classes is not supported.

我的问题是：

1. 我可以在我的方法removeOtherProviderAuthTokenFromSession(request,provider) 上使用Mockito.verify()。如果“是”怎么办？ & 如果“否”，为什么？ SocialUtility 是类名，方法是静态的。请求与到达控制器的请求相同。提供者是一个字符串。我不想使用 PowerMockito。

2. 我还想在getOAuthServiceProvider(appCode, provider) 上使用验证。 我该怎么做？

任何帮助都将不胜感激。

Answer 1

使用 Mockito 验证静态方法 -> MockedStatic。

如果方法有参数并且你想验证它，那么它将通过这种方式进行验证：

@Test
void testMethod() {
  try (MockedStatic<StaticProperties> theMock = Mockito.mockStatic(StaticProperties.class)) {
    theMock.when(StaticProperties.getProperty("abc", "xyz", "lmn"))).thenReturn("OK");

    //code .....

    theMock.verify(() -> StaticProperties.getProperty("abc", "xyz", "lmn"));
  }
  
}

1. 您必须使用 PowerMockito，因为仅此 Mockito 无法验证这一点

   PowerMockito.doNothing().when(SocialUtility.class,
                                 "removeOtherProviderAuthTokenFromSession", 
                                 any(MockHttpServletRequest.class),
                                 anyString());
   

2. 您可以模拟您的getSocialAuthServiceProvider() 或在您调用SocialDataAccessController 时窥探它

Answer 3

关于你的第二个问题：

我还想在 getOAuthServiceProvider(appCode, provider) 上使用验证。我该怎么做？

答案可能是这样的：

Mockito.verify(this.getSocialAuthServiceProvider())
       .getOAuthServiceProvider(Mockito.isA(String.class), Mockito.isA(String.class));

如果我遗漏了什么，请告诉我。
