TestNG and user Principal

[kirkor.grzegorz.bernas.com.pl]

Hi!
I try to write test that uses Session Bean with

@In
 Principal userPrincipal;

public class MyTest extends SeamTest {
    private Log log = Logging.getLog(KwerendyTest.class);

    @SuppressWarnings("unused")
    @Test
    private void testMyBean() throws Exception {
        new ComponentTest() {

            @Override
            protected void testComponents() throws Exception {
                EntityManager entityManager = (EntityManager) getInstance("entityManager");

                setValue("#{identity.username}", "admin");
                setValue("#{identity.password}", "");

                invokeMethod("#{identity.login}");
                
                User user = (User) getInstance("logedInUser");     

                /* ... */
            }
        }.run();
    }
}

@Name("logedInUser")
@Scope(ScopeType.SESSION)
@AutoCreate
public class LogedInUser {

    @Logger
    Log log;
    @In
    private Session hibernateSession;

    @In
    Principal userPrincipal;

    @Unwrap
    public User getUser() {

        User user = null;
        String username = userPrincipal.getName();

        /* ... */
    }
}

after that I get this error:

org.jboss.seam.RequiredException: @In attribute requires non-null value: logedInUser.userPrincipal

Why Principal is null?

I resolve my problem.
First of all, I used wrong context. This should be an new FacesRequest();
To set a principal, I need to override method getPrincipalName, without need of login.

 new FacesRequest() {
            public String getPrincipalName() {
                return "admin";
            };
            
            @Override
            protected void updateModelValues() throws Exception {
                setValue("#{identity.username}", "admin");
                setValue("#{identity.password}", "");
            }

            @Override
            protected void invokeApplication() {
                log.info(invokeMethod("#{identity.login}"));
                log.info("principal: " + getValue("#{userPrincipal.name}"));                
                
                /* ... */
            }

        }.run();

and it works,

 
@In
Principal userPrincipal;

is injected.
