用cactus测试servlet

1.  为了使得项目的开发正规化,准备在3u的这个项目中使用专门的测试工具，经过多方面的比较，最后选择cactus，使用工具eclipse3.3+cactus+junit

   还有就是这里的配置只是用于测试Servlet的，当然也可以用同样的方法配置其可以测试Filter,Jsp等，不过可能要换一个新一点的Cactus的包。   

   1.解压cactus安装文件到某一目录下

   2.将lib下的jar拷贝到项目\web-inf\lib 下

   3.创建cactus.properties文件，并加入classpath（可选，在这里是为为了可以直接用eclipse的junit进行测试，所以这里还是加上吧）

   4.我需要被测试的类

package com.test.web;

import java.io.FileNotFoundException;
import java.io.IOException;

import javax.servlet.RequestDispatcher;
// import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import org.jdom.JDOMException;

// import com.ca.website.mainpage.MainPageSupport;
// import com.error.ErrorProcesser;
// import com.jem.orm.sql.BsSQLHandler;
// import com.jem.orm.sql.BsSqlXmlPaser;
import com.jem.transdata.BsFormData;
import com.jem.transdata.BsFormTable;

// import com.orm.util.SQLStatementIDS;

public class LoginEdge extends HttpServlet {

     public boolean isValidUser(HttpServletRequest request) {
         String username = request.getParameter("username");
         String password = request.getParameter("password");
         if (username == null || password == null || !username.equals("justin")
                 || !password.equals("123456")) {
             return false;
         } else {
             return true;
         }
     }
}

package com.test.web;

import java.io.FileNotFoundException;
import java.io.IOException;

import javax.servlet.RequestDispatcher;
// import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import org.jdom.JDOMException;

// import com.ca.website.mainpage.MainPageSupport;
// import com.error.ErrorProcesser;
// import com.jem.orm.sql.BsSQLHandler;
// import com.jem.orm.sql.BsSqlXmlPaser;
import com.jem.transdata.BsFormData;
import com.jem.transdata.BsFormTable;

// import com.orm.util.SQLStatementIDS;

public class LoginEdge extends HttpServlet {

     public boolean isValidUser(HttpServletRequest request) {
         String username = request.getParameter("username");
         String password = request.getParameter("password");
         if (username == null || password == null || !username.equals("justin")
                 || !password.equals("123456")) {
             return false;
         } else {
             return true;
         }
     }
}

6.我的测试类

package com.test;

import org.apache.cactus.ServletTestCase;
import org.apache.cactus.WebRequest;
import com.test.web.LoginEdge;

public class LoginEdgeTest extends ServletTestCase {

     public void beginValidUser(WebRequest webRequest) {
         webRequest.addParameter("username", "justin");
         webRequest.addParameter("password", "123456");
     }

     public void testValidUser() {
         LoginEdge loginServlet = new LoginEdge();
         assertTrue(loginServlet.isValidUser(request));
     }

     public void beginInValidUser(WebRequest webRequest) {
         webRequest.addParameter("username", "guest");
         webRequest.addParameter("password", "guest");
     }

     public void testInValidUser() {
         LoginEdge loginServlet = new LoginEdge();
         assertFalse(loginServlet.isValidUser(request));
     }

}

package com.test;

import org.apache.cactus.ServletTestCase;
import org.apache.cactus.WebRequest;
import com.test.web.LoginEdge;

public class LoginEdgeTest extends ServletTestCase {

     public void beginValidUser(WebRequest webRequest) {
         webRequest.addParameter("username", "justin");
         webRequest.addParameter("password", "123456");
     }

     public void testValidUser() {
         LoginEdge loginServlet = new LoginEdge();
         assertTrue(loginServlet.isValidUser(request));
     }

     public void beginInValidUser(WebRequest webRequest) {
         webRequest.addParameter("username", "guest");
         webRequest.addParameter("password", "guest");
     }

     public void testInValidUser() {
         LoginEdge loginServlet = new LoginEdge();
         assertFalse(loginServlet.isValidUser(request));
     }

}

7.在web.xml需要如下配置

xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4"
xmlns=""
xmlns:xsi=""
xsi:schemaLocation="
<A href="/web-app_2_4.xsd" target=_blank>/web-app_2_4.xsdA>">

<servlet>
<servlet-name>ServletRedirectorservlet-name>
<servlet-class>org.apache.cactus.server.ServletTestRedirectorservlet-class>
servlet>
<servlet>
<servlet-name>ServletTestRunnerservlet-name>
<servlet-class>org.apache.cactus.server.runner.ServletTestRunnerservlet-class>
servlet>

<servlet-mapping>
<servlet-name>ServletRedirectorservlet-name>
<url-pattern>/ServletRedirectorurl-pattern>
servlet-mapping>
<servlet-mapping>
<servlet-name>ServletTestRunnerservlet-name>
<url-pattern>/ServletTestRunnerurl-pattern>
servlet-mapping>

web-app>

   
ServletRedirector     
org.apache.cactus.server.ServletTestRedirector
    
      
ServletTestRunner   
org.apache.cactus.server.runner.ServletTestRunner   
        

    
ServletRedirector     
/ServletRedirector
    
    
ServletTestRunner    
/ServletTestRunner  

8.在cactus.properties需要如下配置

cactus.contextURL =

cactus.servletRedirectorName = ServletRedirector

cactus.enableLogging=true

9开始测试

输入以下 //这里应该是把测试类当作一个suite传给TestRunner来运行，这跟平时用JUnit是一样的。

将出现测试结果：

xml version="1.0" encoding="UTF-8" ?>
- <testsuites>
- <testsuite name="com.test.LoginEdgeTest" tests="2" failures="0" errors="0" time="0.625">
<testcase name="testValidUser" time="0.5" />
<testcase name="testInValidUser" time="0.016" />
testsuite>
testsuites>
