委托方法不适用于Jmockit单元测试

Question

我只想从HttPServletRequest中设置属性。以下是Jmockit的代码片段。

new Expectations() { 
     private final Delegate requestAttributeDelegate = new Delegate() { 

      final Map<String, Object> attributes = new HashMap<String, Object>(); 

      Object getAttribute(String key) { 
       return attributes.get(key); 
      } 

      void setAttribute(String key, Object value) { 
       attributes.put(key, value); 
      } 
     }; { 
     req.getParameter(ParameterConstant.ACTION); result = ActionConstant.REMOVE; 
     req.getParameter(ParameterConstant.EMAIL); result = myEMail; 
     req.getRequestDispatcher(PageConstant.USER_REMOVE_GROUP_FORM); result = dispatcher; 
     req.setAttribute(ConfigurationConstant.GROUPS, groups); result = requestAttributeDelegate; 
     dispatcher.forward(req, resp); times = 1; 
    }}; 

该行的结果：req.setAttribute(ConfigurationConstant.GROUPS, groups); result = requestAttributeDelegate;从不与委托方法一起使用。

这是错误信息提示：

什么这个是错的???

发现了问题：

new Expectations() { 
     private final Delegate requestSetAttributeDelegate = new Delegate() { 

      final Map<String, Object> attributes = new HashMap<String, Object>(); 

      void setAttribute(String key, Object value) { 
       attributes.put(key, value); 
      } 
     }; { 
     req.getParameter(ParameterConstant.ACTION); result = ActionConstant.REMOVE; 
     req.getParameter(ParameterConstant.EMAIL); result = myEMail; 
     req.setAttribute(ConfigurationConstant.GROUPS, groups); result = requestSetAttributeDelegate; 
     req.getRequestDispatcher(PageConstant.USER_REMOVE_GROUP_FORM); result = dispatcher; 
     dispatcher.forward(req, resp); times = 1; 
    }}; 

1）首先，序列的setAttribute被错误插入。它必须在req.getRequestDispatcher行之上。
2）委托方法必须删除getAttribute方法。
