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 ：

 

 

public class MyMethodInfo implements Comparable {     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();     }       public int compareTo(MyMethodInfo o) {        return this . method .getName().compareTo( o. method .getName() );     }   }

 

 

public class MethodArgPanel extends JPanel {       private static final long serialVersionUID = 1L;     private JScrollPane jScrollPane = null ;     private JTextArea argTextArea = null ;       /**       * This is the default constructor       */     public MethodArgPanel() {        super ();        initialize();     }       /**       * This method initializes this       *       * @return void       */     private void initialize() {        this .setSize(246, 230);        this .setLayout( new BorderLayout());        this .add(getJScrollPane(), BorderLayout. CENTER );     }       /**       * This method initializes jScrollPane       *       * @return javax.swing.JScrollPane       */     private JScrollPane getJScrollPane() {        if ( jScrollPane == null ) {            jScrollPane = new JScrollPane();            jScrollPane .setViewportView(getArgTextArea());        }        return jScrollPane ;     }       /**       * This method initializes argTextArea       *       * @return javax.swing.JTextArea          */     private JTextArea getArgTextArea() {        if ( argTextArea == null ) {            argTextArea = new JTextArea();        }        return argTextArea ;     }         public String getText() {        return argTextArea .getText();     }   }  // @jve:decl-index=0:visual-constraint="10,10 "

 

public class MainFrame extends JFrame {       private static final long serialVersionUID = 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 ;       /**       * This method initializes mainSplitPane       *       * @return javax.swing.JSplitPane       */     private JSplitPane getMainSplitPane() {        if ( mainSplitPane == null ) {            mainSplitPane = new JSplitPane();            mainSplitPane .setDividerLocation( 200 );            mainSplitPane .setRightComponent( getLeftSplitPane() );            mainSplitPane .setLeftComponent( getMethodScrollPane() );        }        return mainSplitPane ;     }       /**       * This method initializes leftSplitPane       *       * @return javax.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() );        }        return leftSplitPane ;
