UISpec4J - AbstractMethodError(UISpecToolkit.createKeyboardFocusManagerPeer)

标签: java swing maven uispec4j

我正在构建一个简单的基于Swing的Java应用程序,并希望添加一些简单的端到端测试。我遇到了UISpec4J库,并将其导入我的Maven项目,如下所示:

<dependency>
    <groupId>org.uispec4j</groupId>
    <artifactId>uispec4j</artifactId>
    <version>2.4</version>
    <scope>test</scope>
</dependency>

我还有以下主类:

public class Main
{
    public static void main(String[] args)
    {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                MainWindow window = new MainWindow();
                window.setLocationRelativeTo(null);
                window.setVisible(true);
            }
        });
    }
}

互联网上似乎没有很多关于UISpec4J的资料,但根据我设法找到的一些教程,下面的代码应该可以工作:

public class CanFillInABasicFormTest extends UISpecTestCase
{
    @BeforeClass
    public void setUp() {
        setAdapter(new MainClassAdapter(Main.class, new String[0]));
    }

    @Test
    public void test() 
    {
        Window mainWindow = getMainWindow();
    }
}

但它失败并出现以下异常:

我做错了什么?此外,UISpec4J库是Google向我推荐的第一个库,但我也向其他功能测试库提出了建议。

2 个答案:

答案 0 :(得分:1)

切换到jdk1.6 update 0对我有用。我使用的是jdk1.7,我也遇到了同样的错误。

此外,我认为注释不是必需的,因为你使用的是junit3(扩展UISpecTestCase,扩展了TestCase)

public class CanFillInABasicFormTest extends UISpecTestCase {
    public void setUp() {
        setAdapter(new MainClassAdapter(Main.class, new String[0]));
    }

    public void test() {
        Window mainWindow = getMainWindow();
    }
}

答案 1 :(得分:0)

问题出现在java 1.7之前创建的类<​​em> org.uispec4j.interception.toolkit.UISpecToolkit 中。类 UISpecToolkit 实现抽象类 org.uispec4j.interception.toolkit.ToolkitDelegate ToolkitDelegate 扩展了另一个抽象类 SunToolkit 。类 SunToolkit 是问题的根源。在Java 1.7中有一个新的抽象方法:

  

KeyboardFocusManagerPeer sun.awt.SunToolkit.getKeyboardFocusManagerPeer()

此方法未在UISpecToolkit类中实现。在Java 1.7中的 SunToolkit 中也是新方法:

  

protected abstract boolean syncNativeQueue(final long timeout);

无法轻松地将此 SunToolkit 的新实现添加到uispec4j。因此,如果没有新的库发布或一些非常重要的努力,它就无法在java 1.7中使用uispec4j库。
