[FIXED] Mockito Verify : Wanted but not invoked error

Issue

I am actually trying to do below: My service class

 @Service   
    public class serviceclass{
    
    @Autowired  
    MessageReplyingSender rclass;
    
    public void doMethod(){
    Object o = rlcass.something("hey","hey",null,1000);
    }
    }
    
    public interface MessageReplyingSender {
    
        public <T> Object something(String sendertopic,T message,Map<String, Object> headers, long replyTimeout)
                throws Exception;
    }
    
    
    
    Test Class:  
    @RunWith(MockitoJUnitRunner.class)  
    public class testclass{  
    @InjectMocks  
        private serviceclass sclass;
        
        @Mock
        MessageReplyingSender rclass;
    
       public void test throws Exception{
    Mockito.verify(rclass).something(Mockito.anyString(), Mockito.anyString(), Mockito.any(), Mockito.anyLong());

Mockito.when(rclass.something(Mockito.anyString(), Mockito.anyString(), Mockito.any(), Mockito.anyLong())).thenReturn("gh");
sclass.doMethod();
        
            
    }
    }

This gives me wanted by not invoked,actually there were Zero interactions with this mock. Any idea what am i doing wrong??

Solution

You're verifying that rclass#something is called. But that's not happening because you forgot to trigger it with serviceclass#doMethod
