如何在静态方法上使用 Mockito.verify()？

Question

I am working on Junit & Mockito. In my project I have a SocialDataAccess Controller whose code goes like this:

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;
    }

}

This is what I have done. I have made a request and my request successfully calls my controller. When I try to use Mockito.verify() to test whether my static method is called or not, I get an error as shown below.

@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());          

    }
}

The error which I got:

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).

My questions are:

1. Can I use Mockito.verify() on my method removeOtherProviderAuthTokenFromSession(request,provider) . If "yes" How? & If "NO" why? SocialUtility is the name of class and the method is static. Request is the same request which comes to the controller. And provider is a string. I don't want to use PowerMockito.

2. I also want to use verify on getOAuthServiceProvider(appCode, provider) . How can I do this?

Any Help would be appreciable.

Answer 1

To verify a static method using Mockito -> MockedStatic.

If the method has parameters and you want to verify it then it will be verify by this way:

@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"));
  }
  
}

Answer 2

1. You have to use PowerMockito for this Mockito alone wont be able to verify this

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

2. You can mock your getSocialAuthServiceProvider() or spy it when you call your SocialDataAccessController

Answer 3

Regarding your 2nd question:

I also want to use verify on getOAuthServiceProvider(appCode, provider). How can I do this?

Answer may be like this:

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

Let me know if I'm missing something.
