这是我的testCase：

public class TelekanalServiceImpltest extends GWTTestCase {

    @Override
    public String getModuleName() {
        // Todo Auto-generated method stub
        return "com.karq.tvkava.tvkavaJUnit";
    }



    public void testTelekanalService(){
        // Create the service that we will test.
        TelekanalServiceAsync telekanalService = GWT.create(TelekanalService.class);
        ServiceDefTarget target = (ServiceDefTarget) telekanalService;
        target.setServiceEntryPoint(GWT.getModuleBaseURL() + "tvkava/telekanalService");

        // Since RPC calls are asynchronous,we will need to wait for a response
        // after this test method returns. This line tells the test runner to wait
        // up to 10 seconds before timing out.
        delayTestFinish(10000);
        //Test data
        Telekanal telekanal = new Telekanal();
        telekanal.setNimetus("test");
        telekanal.setKirjeldus("see on test");
        // Send a request to the server.
        telekanalService.saveOrUpdateTelekanal(telekanal,new AsyncCallback<Void>() {
          public void onFailure(Throwable caught) {
            // The request resulted in an unexpected error.
            fail("Request failure: " + caught.getMessage());
          }

          public void onSuccess(Void result) {
            // Verify that the response is correct.
            boolean isSaved = true;
            assertTrue(isSaved);
            // Now that we have received a response,we need to tell the test runner
            // that the test is complete. You must call finishtest() after an
            // asynchronous test finishes successfully,or the test will time out.
            finishtest();
          }
        });
    }

}

在com.karq.tvkava中,我有一个名为tvKavaJUnit.gwt.xml的模块文件

<?xml version="1.0" encoding="UTF-8"?>
<module>
  <!-- Inherit our applications main module.                      -->
  <inherits name='com.karq.tvkava.tvkava'/>

  <!-- Specify the path to any remote services.                   -->
  <servlet path="/tvkava/telekanalService" class="com.karq.tvkava.server.services.TelekanalServiceImpl" />

</module>

而且我的主要模块在com.karq.tvkava和它的名为tvkava.gwt.xml
