JSFServerSession null

[victoria122]

 // Send an HTTP request for the initial page
 JSFSession jsfSession = new JSFSession("/index.jsp");

Hi Victoria,

Luckily, this does look like a simple one. The initial page needs to map to the FacesServlet. The above line should something like:

JSFSession jsfSession = new JSFSession("/index.jsf");

See the javadoc for JSFSession here for more details:
http://www.jboss.org/file-access/default/members/jsfunit/freezone/apidocs/org/jboss/jsfunit/jsfsession/JSFSession.html#JSFSession(java.lang.String)

Thanks for using JSFUnit.

Oops, looks like I wiped out the original post. Here is the original text:

Hello,

I've downloaded the new version (B3) and have been trying to get a few tests to work. After a little struggling with the jar files, It's now got past the class not found exceptions and on to a new one:

java.lang.NullPointerException
at org.jboss.jsfunit.jsfsession.JSFServerSession.getCurrentViewID(JSFServerSession.java:69)

The same thing occurs for the two tests I have,
Here's the code for one test(you might recognise it):

| package uk.co.inl.tracking.presentation.junit.scanner;
|
| import java.io.IOException;
|
| import javax.faces.component.UIComponent;
|
| import junit.framework.Test;
| import junit.framework.TestSuite;
| import org.jboss.jsfunit.jsfsession.JSFClientSession;
| import org.jboss.jsfunit.jsfsession.JSFServerSession;
| import org.jboss.jsfunit.jsfsession.JSFSession;
| import org.xml.sax.SAXException;
|
|
| public class JSFUnitTest extends org.apache.cactus.ServletTestCase
| {
| public static Test suite()
| {
| return new TestSuite( JSFUnitTest.class );
| }
|
| public void testInitialPage() throws IOException, SAXException
| {
| // Send an HTTP request for the initial page
| JSFSession jsfSession = new JSFSession("/index.jsp");
|
| // A JSFClientSession emulates the browser and lets you test HTML
| JSFClientSession client = jsfSession.getJSFClientSession();
|
| // A JSFServerSession gives you access to JSF state
| JSFServerSession server = jsfSession.getJSFServerSession();
|
| // Test navigation to initial viewID
| assertEquals("/index.jsp", server.getCurrentViewID());
|
| // Assert that the prompt component is in the component tree and rendered
| UIComponent prompt = server.findComponent("greeting");
| assertTrue(prompt.isRendered());
|
| // Test a managed bean
| assertEquals("Stan", server.getManagedBeanValue("#{foo.text}"));
| }
| }
|

when it gets to assertEquals("/index.jsp", server.getCurrentViewID());
server is not null, but the two fields inside are null and hence getCurrentViewID() will throw the following exception:

null

I'm hoping it's something really simple.
Any ideas?
Thank you

Hi Stan,

Thank you for the response.
I must admit I was being lazy. Anyway, after your responce, I added the faces stuff and tried again, but no luck. Probably something to do with the fact that I'd created a new project and had left something vital out. So I decided to try again and place the JSFUnit tests in my main project and have now got the tests working well.

Thank you
Victoria

P.s The new version (B3) is very good. I had some tests written in htmlunit before which were very complicated and long. The same tests have been re-written using JSFUnit with less code and complications.

Great to hear. Thanks for using JSFUnit.

I'm still seeing a very similar issue. This is my first time trying JSFUnit, so I'm trying to get a simple testcase to work. I'm getting a JSFServerSession back from the JSFSession, but both the clientIDs and currentFacesContext are null. This results in a NPE for any calls using the JSFServerSession.

Here's my test case:

import java.io.IOException;
import javax.faces.component.UIComponent;
import junit.framework.Test;
import junit.framework.TestSuite;
import org.apache.cactus.ServletTestCase;
import org.jboss.jsfunit.jsfsession.JSFClientSession;
import org.jboss.jsfunit.jsfsession.JSFServerSession;
import org.jboss.jsfunit.jsfsession.JSFSession;
import org.xml.sax.SAXException;

public class JSFUnitTest extends ServletTestCase {

 public static Test suite()
 {
 return new TestSuite( JSFUnitTest.class );
 }

 public void testInitialPage() throws IOException, SAXException
 {
 // Send an HTTP request for the initial page
 JSFSession jsfSession = new JSFSession("/test.faces");

 // A JSFClientSession emulates the browser and lets you test HTML
 JSFClientSession client = jsfSession.getJSFClientSession();

 // A JSFServerSession gives you access to JSF state
 JSFServerSession server = jsfSession.getJSFServerSession();

 // Test navigation to initial viewID
 try{
 assertEquals("/test.jsp", server.getCurrentViewID());
 }
 catch(Throwable e)
 {
 e.printStackTrace();
 }

 // Assert that the prompt component is in the component tree and rendered
 UIComponent prompt = server.findComponent("text1");
 assertTrue(prompt.isRendered());

 // Test a managed bean
 //assertEquals("Stan", server.getManagedBeanValue("#{foo.text}"));
 }

}

Both of the actions on the server(JSFServerSession) object result in a NPE. Here's the stacktrace:

Is there something I could be missing in my configuration? I added the required filters and servlets mentioned in the "Getting Started" guide. All JSFUnit and the web content that it's trying to test is deployed in a single war file. I can access my "Hello World" jsp file at /test.faces without any problems. Any ideas? Let me know if you need more details. Thanks, Mike

Hi,

You need a workaround for WebSphere. I just created a new wiki page for it. Please let me know if the wiki solves your problem:

Hi Stan,

Yes, the workaround you documented worked like a charm! Thanks!
