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;       /**      *Thisisthedefaultconstructor      */     public MethodArgPanel() {        super();        initialize();     }       /**      *Thismethodinitializesthis      *      *@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();        }        returnargTextArea;     }         public String getText() {        returnargTextArea.getText();     }   } // @jve:decl-index=0:visual-constraint="10,10"

 

publicclass MainFrame extends JFrame {       privatestaticfinallongserialVersionUID = 1L;       private JPanel jContentPane = null;       private JSplitPane mainSplitPane = null;       private JSplitPane leftSplitPane = null;       private JPanel cmdPanel = null;       private JButton execButton = null;       private JScrollPane argsScrollPane = null;       private JPanel argsPanel = null;       private JScrollPane resultScrollPane = null;       private JTextArea resultTextArea = null;       private JScrollPane methodScrollPane = null;       private JList methodList = null;       private MethodArgPanel[] methodArgPanels;       private Object proxy;       /**      *ThismethodinitializesmainSplitPane      *      *@returnjavax.swing.JSplitPane      */     private JSplitPane getMainSplitPane() {        if ( mainSplitPane == null ) {            mainSplitPane = new JSplitPane();            mainSplitPane.setDividerLocation( 200 );            mainSplitPane.setRightComponent( getLeftSplitPane() );            mainSplitPane.setLeftComponent( getMethodScrollPane() );        }        returnmainSplitPane;     }       /**      *ThismethodinitializesleftSplitPane      *      *@returnjavax.swing.JSplitPane      */     private JSplitPane getLeftSplitPane() {        if ( leftSplitPane == null ) {            leftSplitPane = new JSplitPane();            leftSplitPane.setOrientation( JSplitPane.VERTICAL_SPLIT );            leftSplitPane.setDividerSize( 8 );            leftSplitPane.setDividerLocation( 400 );            leftSplitPane.setBottomComponent( getResultScrollPane() );            leftSplitPane.setTopComponent( getCmdPanel() );        }        returnleftSplitPane;
