不使用容器 进行 测试 jsp

参照： 容器外的JSP页面测试技术
由于上面给出例 复杂 。一般人很难理解。我也是 ^_^
但仔细看我还是自己写出一个比较简单的，望大家一起讨论。

被测试jsp

<% @ taglib prefix = " html "  uri = " /WEB-INF/struts-html.tld "   %>
<% @ taglib prefix = " c "  uri = " /WEB-INF/c-1_0-rt.tld "   %>
< html:html >
     < c:if  test ="${name != pass}" >
       ${name}   < br >
       ${pass}  < br >
       <!-- <html:text property="in" ></html:text> -->
     </ c:if >
</ html:html >

ant直接把他放在 eclipes 工程的根目录下 build.xml
    但有有3个参数要设置 tomcat.home  Tomcat 的地址
                        webapp.path 工程中的根目录，下面有WEB-INF
                        src 原代码 （到时候jsp会翻译成.java
                                    到这个目录的 org.apache.jsp.jsp 下）

< project  name ="Webapp Precompilation"  default ="all"  basedir ="." >  

   <!--  tomcat dir  -->
   < property  name ="tomcat.home"  value ="D:\Tomcat 5.0" />
  
   <!--  this=..//WEB-INF (in eclipes)   -->
   < property  name ="webapp.path"  value =".\WebRoot" />
   <!--  src (in eclipes)  -->
   < property  name ="src"  value ="./src" />

TEST

package  jetty.test.supper;


import  javax.servlet.http.HttpServletRequest;
import  javax.servlet.http.HttpServletResponse;

import  org.apache.jsp.jsp.MyJsp_jsp;

import  com.meterware.httpunit.GetMethodWebRequest;
import  com.meterware.httpunit.WebRequest;
import  com.meterware.httpunit.WebResponse;
import  com.meterware.servletunit.InvocationContext;
import  com.meterware.servletunit.ServletRunner;
import  com.meterware.servletunit.ServletUnitClient;

import  junit.framework.TestCase;

public   class  JSPCTest  extends  TestCase{
     private  InvocationContext ic  =   null  ;

     protected   void  setUp()  throws  Exception {
        ServletRunner sr  =   new  ServletRunner();
            //  向环境中注册 jsp
        sr.registerServlet( " HelloWorld " , MyJsp_jsp. class .getName());
        ServletUnitClient  sc  =  sr.newClient();
        WebRequest request  =   new  GetMethodWebRequest( " http://localhost/HelloWorld " );
         ic  =  sc.newInvocation(request);

    }
    
     public   void  testJspC()  throws  Exception{
        HttpServletRequest re  =   ic .getRequest();
        HttpServletResponse rq  =   ic.getResponse();
        re.setAttribute( " name " , " liukaiyi " );
        re.setAttribute( " pass " , " 123456 " );
        
        MyJsp_jsp is  =  (MyJsp_jsp) ic.getServlet();
        is._jspService(re,rq);
        
        WebResponse response  =  ic.getServletResponse();
// 输出
        System.out.println( response.getText() );
        
    }
}

结果是

< html >
    
       liukaiyi   < br >
       123456  < br >
    
    
</ html >

后面用 HttpUnit 和 HtmlUnit 测试就不用我说了把 网上一大把。
