What is the Maven config to run GWT test with GAE runtime

What is the needed POM configuration to test a GWT library on top a a GAE Runtime?

Such that when running $mvn install it will run test for the GWT library.

I am having this idea to test a GWT library (this is not working just my idea):

public class LocalDatastoreTest {
    private final LocalServiceTestHelper helper =
            new LocalServiceTestHelper(new LocalDatastoreServiceTestConfig());  

    @Before
    public void setUp() {
        helper.setUp();
    }

    @After
    public void tearDown() {
        helper.tearDown();
    }   

    @Test
    public void testGWTLibrary() {
       Glimpsecode gcode = new Glipsecode(); // <-- GWT library
       gcode.put("testId", "testType", "testJSON", new GlimpsecodeCallback() {
               @Override
               public void success(Object o) {
                  // test response object  
               }
           }
           @Override
           public void failure(Throwable throwable) {
             // stuff
           }
        });
    }

}

The GWT library about is working fine in a separate GWT + GAE application (by running mvn gwt:codeserver then running mvn appengine:devserver. However to keep things test driven, we need to add testing inside the GWT library.

The GWT library:

• Uses Restlet-GWT to call a RESTlet service (and uses GWT.create() internally)


• The Restlet service saves the request from GWT (via Restlet-GWT) to the Datastore

How can I test this code? Where it is important that the test will access the localhost GAE, not just a mock test.
