Error No ModelAndView found

Hello, just starting to learn spring, maven, hibernate. Trying to write a simple crud application. I launch, jumps out the error java.lang.AssertionError: No ModelAndView found. Could you tell me what could be the problem? Test class:

@RunWith(SpringJUnit4ClassRunner.class) @WebAppConfiguration @ContextConfiguration("file:src/main/webapp/WEB-INF/mvc-dispatcher-servlet.xml") public class AppTests { private MockMvc mockMvc; @SuppressWarnings("SpringJavaAutowiringInspection") @Autowired protected WebApplicationContext wac; @Before public void setup() { this.mockMvc = webAppContextSetup(this.wac).build(); } @Test public void simple() throws Exception { mockMvc.perform(get("/")) .andExpect(status().isOk()) .andExpect(view().name("hello")); } } 

Controller:

 @Controller public class UserController { private UserService userService; @Autowired(required = true) @Qualifier(value = "userService") public void setUserService(UserService userService) { this.userService = userService; } @RequestMapping(value = "/users", method = RequestMethod.GET) public String listUsers(Model model){ model.addAttribute("user", new User()); model.addAttribute("listUsers", this.userService.getListUsers()); return "users"; } @RequestMapping(value = "/users/add", method = RequestMethod.POST) public String addUser(@ModelAttribute("user") User user){ if(user.getId() == 0){ this.userService.addUser(user); }else { this.userService.updateUser(user); } return "redirect:/users"; } @RequestMapping("/remove/{id}") public String removeUser(@PathVariable("id") int id){ this.userService.removeUser(id); return "redirect:/users"; } @RequestMapping("edit/{id}") public String editUser(@PathVariable("id") int id, Model model){ model.addAttribute("user", this.userService.getUserById(id)); model.addAttribute("listUsers", this.userService.getListUsers()); return "users"; } @RequestMapping("/userdata/{id}") public String userData(@PathVariable("id") int id, Model model){ model.addAttribute("user", this.userService.getUserById(id)); return "userdata"; } }
