Cactus借助Jetty测试Servlet

这是一个WebProject，但不需要web.xml，因为用不到它

 

首先是待测试的LoginServlet.java

 

package com.jadyer.servlet;



import java.io.IOException;

import java.io.PrintWriter;



import javax.servlet.ServletException;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;



public class LoginServlet extends HttpServlet {

	private static final long serialVersionUID = 6655227641354075528L;



	@Override

	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

		PrintWriter out = response.getWriter();

		out.println("<table><tr><td>username</td><td>password</td></tr></table>");

		out.flush();

		out.close();

	}

	

	public boolean login(HttpServletRequest request){

		String loginUser = (String)request.getSession().getAttribute("loginUser");

		if(null==loginUser || !"http://blog.csdn.net/jadyer".equals(loginUser)){

			System.out.println("用户[" + loginUser + "]登录失败");

			return false;

		}

		System.out.println("用户[" + loginUser + "]登录成功");

		return true;

	}

}

下面是Cactus编写的位于test SourceFolder下的测试用例LoginServletTest.java

 

其实它和上一篇文章"Cactus入门"里面的测试用例是一样的

 

package com.jadyer.servlet;



import java.io.IOException;



import javax.servlet.ServletException;



import junit.framework.Assert;



import org.apache.cactus.ServletTestCase;

import org.apache.cactus.WebRequest;

import org.xml.sax.SAXException;



import com.meterware.httpunit.WebResponse;



public class LoginServletTest extends ServletTestCase {

	private LoginServlet loginServlet;

	

	//它是在ServerSide执行的

	public void setUp(){

		loginServlet = new LoginServlet();

	}

	

	//beginXxx()方法是在ClientSide执行的

	//如果想在testLogin()中获取到这里request添加的username参数,那么这个方法就应该命名为beginLogin()

	public void beginLogin(WebRequest request){

		request.addParameter("username", "Jadyer");

	}

	

	//它是在ServerSide执行的

	public void testLogin(){

		//获取GET参数

		Assert.assertEquals(request.getParameter("username"), "Jadyer");

		//登录失败

		//session.setAttribute("loginUser", "玄玉<http://blog.csdn.net/jadyer>");

		Assert.assertFalse(loginServlet.login(request));

		//登录成功

		session.setAttribute("loginUser", "http://blog.csdn.net/jadyer");

		Assert.assertTrue(loginServlet.login(request));

	}

	

	//它是在ServerSide执行的

	public void testDoGet() throws ServletException, IOException {

		loginServlet.doGet(request, response);

	}

	

	//endXxx()方法是在ClientSide执行的,该方法对应testDoGet()

	public void endDoGet(WebResponse resp) throws SAXException {

		//这里使用com.meterware.httpunit.WebResponse,而非org.apache.cactus.WebResponse,前者提供了很多增强功能

		//但在使用httpunit中的WebResponse时,要额外借助Tidy.jar作为辅助包

		Assert.assertEquals(resp.getTables()[0].getCellAsText(0,0), "username");

		Assert.assertEquals(resp.getTables()[0].getCellAsText(0,1), "password");

	}

}

最后是JUnit3.8编写的测试套件TestAllUseJetty.java（为什么这么用，详见注释）

 

 

package com.jadyer.servlet;



import junit.framework.Test;

import junit.framework.TestSuite;



import org.apache.cactus.extension.jetty.Jetty5xTestSetup;



/**

 * Jetty中使用Cactus测试Servlet步骤如下

 * @see 0)Cactus下载地址为http://archive.apache.org/dist/jakarta/cactus/

 * @see   关于Jetty的简单用法,可参考我的博文http://blog.csdn.net/jadyer/article/details/9299485

 * @see 1)加入所依赖的jar

 * @see   aspectjrt-1.5.3.jar

 * @see   cactus.core.framework.uberjar.javaEE.14-1.8.1.jar

 * @see   cactus.integration.ant-1.8.1.jar

 * @see   cactus.integration.shared.api-1.8.1.jar

 * @see   commons-codec-1.6.jar

 * @see   commons-discovery-0.4.jar

 * @see   commons-httpclient-3.1.jar

 * @see   commons-logging-1.1.jar

 * @see   geronimo-j2ee-management_1.0_spec-1.1.jar

 * @see   httpunit-1.6.jar

 * @see   nekoHTML.jar

 * @see   xercesMinimal.jar

 * @see   org.mortbay.jetty-5.1.9.jar(取自cactus-1.8.1-bin.zip)

 * @see 2)编写测试用例

 * @see   这里即LoginServletTest.java

 * @see 3)编写测试套件

 * @see   我们要在beginXxx之前启动Jetty,而Cactus不支持JUnit4中的annotation

 * @see   所以为了实现类似@BeforeClass的功能,我们就借助JUnit3.8中测试套件,最后测试时直接运行此测试套件即可

 * @see   关键JUnit3.8和JUnit4的测试套件编写规则,详见http://blog.csdn.net/jadyer/article/details/6013743

public class TestAllUseJetty {

	public static Test suite(){

		//此时就不需要cactus.properties文件了,并且注意这里的值就不能以下划线结尾了,而端口则可任意设定

		//另外在web.xml中也不需要配置org.apache.cactus.server.ServletTestRedirector及其映射了

		System.setProperty("cactus.contextURL", "http://127.0.0.1:8088/testJettyAndCactus");

		

		TestSuite suite = new TestSuite();
