unit-testing - 如何配置 GWTTestCase 扩展类

我想为我创建的 GWT 复合组件编写测试用例，我有一个扩展 com.google.gwt.user.client.ui.Composite 的类 Count，在这个 Count 中我有一个文本框和一些处理程序根据值显示标签。

现在我想为这个类写测试用例，我试过下面的代码，但它总是显示相同的错误:java.lang.NoSuchMethodError: org.mortbay.thread.Timeout.(Ljava/lang/Object;)V

我的代码是:

    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
    }
}

我还想知道 getModuleName() 方法有什么用？我已经给出了被测类的字符串路径。

完整的错误信息是:

最佳答案

请检查 Google GWT 团队如何为小部件编写测试用例。您可以在 GitHub 上的 GWT 存储库中找到示例。 .

实现 getModuleName() 以便它返回反射(reflect) GWT 模块文件 com.rubirules.uibuilder.UIbuilder 路径的字符串。
