java - UISpec4J - AbstractMethodError(UISpecToolkit.createKeyboardFocusManagerPeer)

Question

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。我遇到过UISpec4J库并将其导入到我的 Maven 项目中，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 Material ，但根据一些教程，我设法找到以下代码应该可以工作:

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

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

但是它失败并出现以下异常:

我做错了什么？另外，UISpec4J 库是 Google 向我推荐的第一个库，但我也愿意征求其他功能测试库的建议。

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

而且，我认为注释不是必需的，因为您使用的是junit3(扩展UISpecTestCase，即扩展TestCase)

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

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