Problem using MockRoundtrip class

问题

I have following code:

@Test
 public void testSaveValid() throws Exception {
  MockRoundtrip trip = new MockRoundtrip(mockServletContext,
    ContactFormActionBean.class, mockSession);

  trip.setParameter("contact.email", "test@test.com");
  trip.setParameter("contact.phoneNumber", "654-456-4567");
  trip.execute("save");

  ContactFormActionBean bean =
   trip.getActionBean(ContactFormActionBean.class);

  assertEquals(0,
    bean.getContext().getValidationErrors().size());

  PhoneNumber pn = bean.getContact().getPhoneNumber();
  assertEquals("654", pn.getAreaCode());
  assertEquals("456", pn.getPrefix());
  assertEquals("4567", pn.getSuffix());

  assertTrue(
    trip.getDestination().startsWith("/ContactList.action"));
 }

I encounter this error:

If I delete

trip.setParameter("contact.email", "test@test.com");
trip.setParameter("contact.phoneNumber", "654-456-4567");

I won't get any errors but will get following message from jUnit:

java.lang.AssertionError: expected:<0> but was:<1>

which seems logical. This is my ContactFormActionBean class

public class ContactFormActionBean extends ContactBaseActionBean {
private static final String FORM="/WEB-INF/jsp/contact_form.jsp";

@DefaultHandler
public Resolution form() {
    return new ForwardResolution(FORM);
}
public Resolution save() {
    Contact contact = getContact();
    contact.setUser(getUser());
    contactDao.save(contact);
    contactDao.commit();
    getContext().getMessages().add(
        getLocalizableMessage("contactSaved", contact)
    );
    return new RedirectResolution(ContactListActionBean.class);
}
@ValidationMethod(on="save")
public void validateEmailUnique(ValidationErrors errors) {
    String email = getContact().getEmail();
    Contact other = contactDao.findByEmail(email, getUser());
    if (other != null && !other.equals(getContact())) {
        errors.add("contact.email", new LocalizableError(
          getClass().getName()+".contactEmailAlreadyUsed", other));
    }
    }
}

Why this error happens?

[ADDED]

This is my Setup() function where I configure mockServletContext before running any test functions:

... 
    private static MockServletContext mockServletContext;
    private static MockHttpSession mockSession;

    @BeforeClass
    public static void setup() throws Exception {
        mockServletContext = new MockServletContext("webmail");

        Map<String,String> params = new HashMap<String,String>();
        params.put("ActionResolver.Packages", "stripesbook.action");

        params.put("Extension.Packages", "stripesbook.ext,"
                + "net.sourceforge.stripes.integration.spring");

        mockServletContext.addFilter(StripesFilter.class,
                "StripesFilter", params);

        mockServletContext.setServlet(DispatcherServlet.class,
                "DispatcherServlet", null);

        mockSession = new MockHttpSession(mockServletContext);


        mockServletContext.addInitParameter("contextConfigLocation",
        "/WEB-INF/applicationContext-test.xml");

        ContextLoaderListener springContextLoader =
            new ContextLoaderListener();
        springContextLoader.contextInitialized(
                new ServletContextEvent(mockServletContext));
        // Load mock user
        MockRoundtrip trip = new MockRoundtrip(mockServletContext,
                MockDataLoaderActionBean.class, mockSession);
        trip.execute();

        // Login mock user
        trip = new MockRoundtrip(mockServletContext,
                LoginActionBean.class, mockSession);
        trip.setParameter("username", "freddy");
        trip.setParameter("password", "nadia");
        trip.execute("login");
    }
...

I think there could be some config problems cause when I remove

<classpathentry kind="src" path="src/main/webapp" /> 

from class path I get different error :

org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from ServletContext resource [/WEB-INF/applicationContext-test.xml]; nested exception is java.io.FileNotFoundException: Could not open ServletContext resource [/WEB-INF/applicationContext-test.xml]

回答1:

There seems to be a Stripes configuration problem.

Did you configure the mockServletContext correctly?

回答2:

U tried with Spring ?

I have done it with :

Object test= springContextListener.getContextLoader().getCurrentWebApplicationContext().getBean("MyActionBean");

annoted your class with : @RunWith(SpringJUnit4ClassRunner.class)

回答3:

concerning org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from ServletContext resource [/WEB-INF/applicationContext-test.xml]; nested exception is java.io.FileNotFoundException: Could not open ServletContext resource [/WEB-INF/applicationContext-test.xml]

add :

@RunWith(SpringJUnit4ClassRunner.class to your test Class

and add Spring-test Jar to your project.

回答4:

recheck the line : filterParams.put("ActionResolver.Packages", "yourapplicationpackagesPath.action");
