MockMvc: forwardedUrl is null

Question

I am having problems to make this test work. Assertion always fails because it can't verify forwardedUrl which is always null. If I remove this assumption, it can't verify return model. I suppose it is due to missing forwarded Url. My test class looks like this:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:test-application-config.xml"})
@WebAppConfiguration
public class UserControllerTest {
  private MockMvc mockMvc;

  @Mock
  private UserService userServiceMock;

  @Inject 
  private WebApplicationContext wac;

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

  @Test
  public void users_ShouldAddUserEntriesToModelAndRenderUserListView() throws Exception {
    User firstUser = generateSampleUser("Pera", "Peric");
    User secondUser = generateSampleUser("Maja", "Majic");

    when(userServiceMock.getAllUsers()).thenReturn(Arrays.asList(firstUser, secondUser));

    mockMvc.perform(get("/users"))
         .andExpect(status().isOk())
         .andExpect(view().name("users"))
         .andExpect(forwardedUrl("/WEB-INF/velocity/users.vm"))
         .andExpect(model().attribute("users", hasSize(2)))
         .andExpect(model().attribute("users", hasItem(
                 allOf(
                         hasProperty("id", is(1L)),
                         hasProperty("firstName", is("Pera")),
                         hasProperty("LastName", is("Peric"))
                 )
         )))
         .andExpect(model().attribute("users", hasItem(
                 allOf(
                         hasProperty("id", is(2L)),
                         hasProperty("firstName", is("Maja")),
                         hasProperty("LastName", is("Majic"))
                 )
         )));

    verify(userServiceMock, times(1)).getAllUsers();
    verifyNoMoreInteractions(userServiceMock);
  }

  private User generateSampleUser(String firstName, String lastName) {
    User user = new User();
    user.setFirstName(firstName);
    user.setLastName(lastName);
    user.setEmail("[email protected]");
    user.setBirthday(new Date());
    user.setGender(Gender.MALE);
    user.setPersonalNumber("1234567890123");

    return user;
  }
}

And test configuration file looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:p="http://www.springframework.org/schema/p"
    xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd">

<import resource="classpath:data-config-hsql.xml" />

<mvc:annotation-driven />

<context:component-scan base-package="com.code9" />

<bean id="velocityConfig"
    class="org.springframework.web.servlet.view.velocity.VelocityConfigurer">
    <property name="resourceLoaderPath" value="/WEB-INF/velocity/" />
</bean>

<bean id="viewResolver"
    class="org.springframework.web.servlet.view.velocity.VelocityLayoutViewResolver">
    <property name="cache" value="true" />
    <property name="prefix" value="" />
    <property name="layoutUrl" value="layout.vm" />
    <property name="suffix" value=".vm" />
    <property name="exposeSessionAttributes" value="true" />
</bean>

I must note that I'm just a beginner with spring mvc and that I'm not familiar with controller tests.

Edit: I forgot to add UserController implementation:

   @Controller
public class UserController {

    @Inject
    private UserService userService;

    @RequestMapping(value = "/users", method = RequestMethod.GET)
    public ModelAndView getAllUsers() {
        List<User> users = userService.getAllUsers();

        return new ModelAndView("users", "users", users);
    }
}

Edit: This is the full stack trace of exception that is causing this problem:

Does it work if you use your production config files instead of your test-application-config?

e.g.

@ContextConfiguration({"file:src/main/webapp/WEB-INF/applicationContext.xml", 
     "file:src/main/webapp/WEB-INF/dispatcher-servlet.xml"})

Maybe you need to add some ../ in the resourceLoaderPath.

e.g.

<property name="resourceLoaderPath" value="../main/webapp/WEB-INF/velocity/" />
