• JUnit test

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration("classpath:/applicationContext.xml")
public class ScopedBeanTests {

  @Autowired
  private UserService userService;
  @Autowired
  private MockHttpServletRequest httpServletRequest;
  @Autowired
  private MockHttpSession httpSession;

  @Test
  public void testScopedBeans() {
    httpServletRequest.setParameter("username", "jdoe");
    httpServletRequest.setParameter("password", "secret");
    httpSession.setAttribute("theme", "blue");
    Assert.assertEquals("jdoe",userService.getLoginAction().getUsername());
    Assert.assertEquals("secret", userService.getLoginAction().getPassword());
    Assert.assertEquals("blue", httpSession.getAttribute("theme"));
