GWTTestSuite - ClassCastException on executing test suite

[Jan]

Hello,

I created a module containing GWTTestCases as described here (I am
using GWT 1.5.2 on Windows XP):

http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5&s=google-web-toolkit-doc-1-5&t=DevGuideJUnitSuites

and here

http://60-248-16-66.hinet-ip.hinet.net/GWT/doc/html/com.google.gwt.doc.DeveloperGuide.JUnitIntegration.html

I have one GWTTestCase class and one GWTTestSuite class. Here is the
code:

8< - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

package test.client;

import junit.framework.Test;
import junit.framework.TestSuite;

import com.google.gwt.junit.tools.GWTTestSuite;

public class TestTestSuite extends GWTTestSuite {

        public static Test suite() {
                TestSuite suite = new TestSuite("Tests");
                suite.addTestSuite(TestTest.class);
                return suite;
        }

}

---

package test.client;

import com.google.gwt.junit.client.GWTTestCase;

public class TestTest extends GWTTestCase {

        @Override
        public String getModuleName() {
                return "test.Test";
        }

        public void testStuff() {
                assertTrue(2 + 2 == 4);
        }

}


>8 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

And here is the Module xml:

<module>

    <inherits name='com.google.gwt.junit.JUnit'/>

</module>

Invoking the test case using the following command line works:

@java -Dgwt.args="-out www-test" -Xmx256M -cp ".\src;.\bin;.\lib
\junit.jar;.\lib\gwt-user.jar;.\lib\gwt-dev-windows.jar"
junit.textui.TestRunner test.client.TestTest %*

Invoking the TestTestSuite using the following command line:

@java -Dgwt.args="-out www-test" -Xmx256M -cp ".\src;.\bin;.\lib
\junit.jar;.\lib\gwt-user.jar;.\lib\gwt-dev-windows.jar"
junit.textui.TestRunner test.client.TestTestSuite %*

fails with the error message:

Error: java.lang.ClassCastException: class test.client.TestTestSuite

I checked the class path several times. All src folders and jars are
present.

I played around with the code a bit. Letting the TestTestSuite class
inherit from GWTTestCase works (to some extend). Here is the changed
code:

package test.client;

import junit.framework.Test;

import com.google.gwt.junit.client.GWTTestCase;
import com.google.gwt.junit.tools.GWTTestSuite;

public class TestTestSuite extends GWTTestCase {


         @Override
        public String getModuleName() {
                return "test.Test";
        }

        public static Test suite() {
                GWTTestSuite suite = new GWTTestSuite("Tests");
                suite.addTestSuite(TestTest.class);
                return suite;
        }

}


Now the test case is run. However, the GWT compiler complains with
some error messages:

Removing units with errors
   [ERROR] Errors in 'file:/<path goes here>/src/test/client/
TestTestSuite.java'
      [ERROR] Line 17: No source code is available for type
com.google.gwt.junit.tools.GWTTestSuite; did you forget to inherit a
required module?

I have no idea which module could be missing.

Any ideas from the GWT experts?

Cheers,

Jan
