我是靠谱客的博主动听小懒虫，最近开发中收集的这篇文章主要介绍写了个Servlet的测试用例，初学单元测试，大家帮我看看。，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

用的JUnit是4.4版，EasyMock2.3。

这是Servlet：

package net.javayuan.servlet;

import java.io.IOException;

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

/**
 * @(#)LoginServlet.java 2008-6-4 下午11:39:05
 * 
 * @author Yuan
 * LoginServlet
 */
public class LoginServlet extends HttpServlet {

	/**

* 

*/
	private static final long serialVersionUID = -7068817837964223972L;

	@Override
	public void doPost(HttpServletRequest request, HttpServletResponse response)
	throws IOException,ServletException{

String username = request.getParameter("username").trim();

String password = request.getParameter("password");

if ("yuan".equals(username) && "123456".equals(password))

response.sendRedirect("welcome.jsp");

else

response.sendRedirect("error.jsp");
	}
}

这是Test Case：

package net.javayuan.servlet;

import static org.easymock.EasyMock.*;

import java.io.IOException;

import org.junit.Test;
import org.junit.After;
import org.junit.Before;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
 * @(#)LoginServlet.java 2008-6-5 上午09:19:42
 * 
 * @author Yuan
 * LoginServlet Test Case
 */
public class LoginServletTest {

	private LoginServlet servlet;
	private HttpServletRequest mockRequest;
	private HttpServletResponse mockResponse;

	@Before
	public void setUp(){


servlet = new LoginServlet();


//创建request和response的Mock

mockRequest = createMock(HttpServletRequest.class);

mockResponse = createMock(HttpServletResponse.class);
	}

	@After
	public void tearDown(){


//为了验证指定的调用行为确实发生了，要调用verify(mock)进行验证。

verify(mockRequest);

verify(mockResponse);
	}

	/**

* 测试doPost方法

* @throws IOException

* @throws ServletException

* */
	@Test
	public void testDoPost() throws IOException, ServletException{


//录制request和response的动作

mockRequest.getParameter("username");

expectLastCall().andReturn("yuan");//设置前一方法被调用时的返回值


mockRequest.getParameter("password");

expectLastCall().andReturn("123456");


mockResponse.sendRedirect("welcome.jsp");


//回放

replay(mockRequest);

replay(mockResponse);


//开始测试Servlet的doPost方法

servlet.doPost(mockRequest, mockResponse);
	}

}
