我在使用GWT和JUnit时遇到了一些问题。
首先，我使用Eclipse IDE，GWT 2.5.1和JUnit 4.我试图使用以下代码运行简单测试：
public class HelloWorldTest extends GWTTestCase {
/**
* must refer to a valid module that sources this class.
*/
public String getModuleName() {
return "helloworld.HelloWorldJUnit";
}
/**
* tests the FieldVerifier.
*/
public void testFieldVerifier() {
assertFalse(FieldVerifier.isValidName(null));
assertFalse(FieldVerifier.isValidName(""));
assertFalse(FieldVerifier.isValidName("a"));
assertFalse(FieldVerifier.isValidName("ab"));
assertFalse(FieldVerifier.isValidName("abc"));
assertTrue(FieldVerifier.isValidName("abcd"));
}
/**
* this test will send a request to the server using the greetServer
* method in GreetingService and verify the response.
*/
public void testGreetingService() {
/* create the service that we will test. */
GreetingServiceAsync greetingService =
GWT.create(GreetingService.class);
ServiceDefTarget target = (ServiceDefTarget) greetingService;
target.setServiceEntryPoint(GWT.getModuleBaseURL()
+ "helloworld/greet");
/* 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);
/* send a request to the server. */
greetingService.greetServer("GWT User",
new AsyncCallback<String>() {
public void onFailure(Throwable caught) {
/* The request resulted in an unexpected error. */
fail("Request failure: " + caught.getMessage());
}
public void onSuccess(String result) {
/* verify that the response is correct. */
assertTrue(result.startsWith("Hello, GWT User!"));
/* 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();
}
});
}
}
我开始测试后出现错误：

我已阅读此GWT+GAE error :failed org.mortbay.jetty.nio.SelectChannelConnector by running GWTTestCase-JUnit但是当我更改订单时，我收到以下错误：
Loading inherited module 'helloworld.HelloWorldJUnit'
[ERROR] Unable to find 'helloworld/HelloWorldJUnit.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source?
Loading inherited module 'helloworld.HelloWorldJUnit'
[ERROR] Unable to find 'helloworld/HelloWorldJUnit.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source?
有人可以给我一个如何解决这个问题的建议吗？
