java - 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 Controller ，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，我的请求成功地调用了我的 Controller 。当我尝试使用 Mockito.verify() 来测试我的静态方法是否被调用时，我收到如下所示的错误。

@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.

    at java.lang.reflect.Method.invoke(Method.java:597).

我的问题是:

1. 我可以在我的方法 removeOtherProviderAuthTokenFromSession(request,provider) 上使用 Mockito.verify() 吗？如果"is"如何？ ＆如果“否”为什么？ SocialUtility 是类名，方法是静态的。请求与到达 Controller 的请求相同。 provider 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？

任何帮助将不胜感激。

使用 Mockito -> MockedStatic 验证静态方法。

如果方法有参数，你想验证它，那么会通过这种方式验证:

@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"));
  }
  
}
