交互测试接口的简单实现 reflect（反射） + XStream

交互测试接口的简单实现

 

1.       问题

或者你已经习惯了写 Hardcode JUnit Test Case。但这里有问题：

l         你写的代码要经过 Java compiler 才可运行，但实际的环境下不一定允许这样

l         很难用于交互测试与开发期的错误跟踪。不能要求你的交互测试环境总有一个 Java IDE。

 

上述问题在 Java Application 的 RMI 接口测试和错误跟踪时就更明显。

 

 

2.       解决方法

要做交互测试与错误跟踪，要面对的情况是不可料的，故很难用 Hardcode 的静态语言 Java 去做。但我对动态语言（如 BeanShell ）也不大了解。但相对比较了解 Java 的反射机制与 XStream(http://xstream.codehaus.org/) 的从 XML 文本到 Java Object 的应用

 

Java 的 reflect（反射） + XStream 的 文本到 Object instance ：

 

 

publicclass MyMethodInfo implements Comparable<MyMethodInfo> {

    public Method method;

 

    public MyMethodInfo(Method method) {

       this.method = method;

    }

 

    public String toString() {

       StringBuilder builder = new StringBuilder();

       builder.append( method.getName() ).append( " (" );

       Class[] params = method.getParameterTypes();

       for( int i = 0 ; i < params.length; i++ ) {

           builder.append( params[i].getSimpleName() );

           if( i < params.length - 1 ) {

              builder.append( ", " );

           }

       }

       builder.append( ')' );

       return builder.toString();

    }

 

    publicint compareTo(MyMethodInfo o) {

       returnthis.method.getName().compareTo( o.method.getName() );

    }

 

}

 

 

publicclass MethodArgPanel extends JPanel {

 

    privatestaticfinallongserialVersionUID = 1L;

    private JScrollPane jScrollPane = null;

    private JTextArea argTextArea = null;

 

    /**

    public MethodArgPanel() {

       super();

       initialize();

    }

 

    /**

     *@returnvoid

     */

    privatevoid initialize() {

       this.setSize(246, 230);

       this.setLayout(new BorderLayout());

       this.add(getJScrollPane(), BorderLayout.CENTER);

    }

 

    /**

     *ThismethodinitializesjScrollPane

     *

     *@returnjavax.swing.JScrollPane

    private JScrollPane getJScrollPane() {

       if ( jScrollPane == null ) {

           jScrollPane = new JScrollPane();

           jScrollPane.setViewportView(getArgTextArea());

       }

       returnjScrollPane;

    }

 

    /**

     *ThismethodinitializesargTextArea

     *

     *@returnjavax.swing.JTextArea  

     */

    private JTextArea getArgTextArea() {

       if ( argTextArea == null ) {

           argTextArea = new JTextArea();

       }
