TestNG - How do I test Seam components?

[charliebarjel]

Hi,

I have written a simple Test to return all users from my LDAP Identity Store.
But the tests always fail with "No application context active".

Im not sure what im doing wrong or I have forgotten to set anything up.

Can anyone help?

package au.com.statewater.koncentrator.test;

import java.util.List;


import org.jboss.seam.Component;
import org.jboss.seam.mock.SeamTest;
import org.jboss.seam.security.management.IdentityManager;
import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;

public class LdapUserTest extends SeamTest {
     
     private IdentityManager identityManager;
     
     @Test
     public void testLdapSearch() {
          
          List<String> users = identityManager.listUsers();
          
          for (String s : users) {
               System.out.println("User: " + s);
          }

    }
    
    @BeforeClass
    public void init() 
    {
         identityManager = (IdentityManager) Component.getInstance("identityManager");
    }
    
    @AfterClass
    public void destroy()
    {
       
    }
}

Hi Charlie,

try this in a @BeforeClass or @BeforeMethod annotated method:

       Lifecycle.beginCall();
       Lifecycle.beginSession(session.getAttributes(), null);

maybe you also need

      Identity.setSecurityEnabled(false);

for testing

Hi Michael,

Thanks for your response.

What library is the Lifecycle class available in?

Thanks

[charliebarjel]

Please ignore my previous Post.

I've run into a couple of exceptions now with the changes you suggested.
Im not sure what im doing wrong.

Test Class:

package au.com.statewater.koncentrator.test;

import java.util.List;


import org.jboss.seam.Component;
import org.jboss.seam.contexts.Lifecycle;
import org.jboss.seam.mock.SeamTest;
import org.jboss.seam.security.management.IdentityManager;
import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;

public class LdapUserTest extends SeamTest {
     
     private IdentityManager identityManager;
     
     @Test
     public void testLdapSearch() {
          
          
          List<String> users = identityManager.listUsers();
          
          for (String s : users) {
               System.out.println("User: " + s);
          }
          
    }
    
    @BeforeClass
    public void init() 
    {     
         begin();
         
         Lifecycle.beginCall();
         Lifecycle.beginSession(session.getAttributes(), null);
         identityManager = (IdentityManager) Component.getInstance("identityManager", true);
         
    }
    
    @AfterClass
    public void destroy()
    {
         end();
         session.invalidate();
         
         Lifecycle.endCall();  
         Lifecycle.endSession(session.getAttributes());
    }
}

Im getting the exceptions:

java.lang.IllegalStateException: Please end the HttpSession via org.jboss.seam.web.Session.instance().invalidate()
     at org.jboss.seam.contexts.Lifecycle.endSession(Lifecycle.java:267)
     at org.jboss.seam.contexts.ServletLifecycle.endSession(ServletLifecycle.java:160)
     at org.jboss.seam.mock.AbstractSeamTest.end(AbstractSeamTest.java:903)
     at org.jboss.seam.mock.SeamTest.end(SeamTest.java:37)

and

java.lang.NullPointerException
     at au.com.statewater.koncentrator.test.LdapUserTest.testLdapSearch(LdapUserTest.java:22)
... Removed 22 stack frames

when trying to invoke the component.
It seems like the component is coming back as NULL.

Not sure why that is.

What am i missing?

Thanks
Charlie

Simply wrap your tests in a FacessRequest, all the mocking and lifecycle call are done for you. Read more here Integration testing Seam application user interactions
