How configure GWTTestCase extended class

Question

I want to write test case for GWT composite component i created, I had class Count which extends com.google.gwt.user.client.ui.Composite and in this Count i had a text box and some handler for this to display labels according to the values.

Now i want to write test case for this class, i tried like code below but it always show same Error : java.lang.NoSuchMethodError: org.mortbay.thread.Timeout.(Ljava/lang/Object;)V

my code is:

    package com.rubirules.uibuilder.client;
import org.junit.Test;
import com.google.gwt.junit.client.GWTTestCase;
public class CountTest extends GWTTestCase {
    @Override
    public String getModuleName() {
        return "com.rubirules.uibuilder.client.Count";
    }
    @Test
    public void testNullConstructor(){  
            assertFalse(true);
                        //TODO need to add some code to test Count class
    }
}

also i want to know what is the use of getModuleName() method? I had given the string path of my class under test.

the compleate error message is:

I recommend you to use gwt-test-utils, It has complete documentations and samples.

sir, actually i feel like my problem is with the getModuleName() method, i don't know exact module path. When i use null and didn't refer on Count it shows no error, but to use Count class i have to give exact module path. Do you know what will be the module path? – Dipak Jan 02 '13 at 09:47
It is the path of your *.gwt.xml located plus module name. For example: com.googlecode.gwt.test.sample.SpringSample – Saeed Zarinfam Jan 02 '13 at 11:53

Please check how Google GWT Team writes test case for widgets. You can find examples in the GWT repository on GitHub.

Implement getModuleName() so that it returns a string which reflects the path to your GWT module file com.rubirules.uibuilder.UIbuilder.

package com.google.gwt.user.client.ui; public class ButtonTest extends GWTTestCase { private static final String html = "helloworld"; @Override public String getModuleName() { return "com.google.gwt.user.User"; } will you tell me what exactly this getModuleName() returns? – Dipak Jan 02 '13 at 09:58
It is a hard coded string "com.google.gwt.user.User" corresponding to gwt module file for gwt-user.jar – appbootup Jan 02 '13 at 10:17
Thank you for that link. I got solved my problem, i changed com.google.appengine.eclipse.sdkbundle_1.7.4 to 1.7.3 and my getNameModule path to com.rubirules.uibuilder.UIbuilder, corresponding to module file. thank you. :) – Dipak Jan 02 '13 at 10:47
