如何配置GWTTestCase扩展类

标签： unit-testing gwt testing junit gwttestcase

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，在此我有一个文本框和一些处理程序根据值显示标签。

现在我想为这个类编写测试用例， 我尝试下面的代码，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
    }
}

我也想知道getModuleName（）方法有什么用？我给了我班上的字符串路径。

完成错误消息是：

我建议您使用gwt-test-utils，它有完整的文档和samples。

请检查Google GWT团队如何为小部件编写测试用例。您可以在google gwt trunk代码中查看它们 - http://code.google.com/p/google-web-toolkit/source/browse/trunk/user/test/com/google/gwt/user/client/ui

使用评论回复编辑：

更改getModuleName（）返回字符串以反映gwt模块文件的路径 com.rubirules.uibuilder.UIbuilder 。
