spring集成TestNg测试

1，在eclipse中安装TestNg插件，这里省略。。

2，编写测试spring Dao层的代码

package test.com.smart.dao;import com.smart.dao.UserDao;import com.smart.domain.User;import com.smart.service.UserService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.testng.AbstractTestNGSpringContextTests;import org.testng.annotations.Test;import java.util.Date;import static org.testng.Assert.assertEquals;import static org.testng.Assert.assertNotNull;import static org.testng.Assert.assertTrue;@ContextConfiguration(locations = {"classpath:resources/applicationContext.xml"})public class UserDaoTest extends AbstractTestNGSpringContextTests {    @Autowired    private UserDao userDao;    @Test    public void hasMatchUser() {        int count  = userDao.getMatchCount("admin1", "123456");        assertTrue(count>0);    }    @Test    public void findUserByUserName() {        User user = userDao.findUserByUserName("admin");        assertNotNull(user);        assertEquals(user.getUserName(), "admin");    }}

注意：@ContextConfiguration(locations = {"classpath:resources/applicationContext.xml"})这个注解是的localtion属性使用的是src类路径下面的

resources/applicationContext.xml spring配置文件

2，由于TestNg测试持久层和测试服务层十分类似，这里省略了，这里给出测试层的代码

a,项目编写封装了客户端请求的类

package com.smart.web;public class LoginCommand {    private String userName;    private String password;    public String getPassword() {        return password;    }    public void setPassword(String password) {        this.password = password;    }    public String getUserName() {        return userName;    }    public void setUserName(String userName) {        this.userName = userName;    }}

b.下面编写控制类的代码

package com.smart.web;import java.util.Date;import javax.servlet.http.HttpServletRequest;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.servlet.ModelAndView;import com.smart.domain.User;import com.smart.service.UserService;@Controller@RequestMapping(value = "/admin")public class LoginController {    @Autowired    private UserService userService;    @RequestMapping(value = "/login.html")    public String loginPage() {        return "login";    }    @RequestMapping(value = "/loginCheck.html")    public ModelAndView loginCheck(HttpServletRequest request, LoginCommand loginCommand) {        boolean isValidUser =                userService.hasMatchUser(loginCommand.getUserName(),                        loginCommand.getPassword());        if (!isValidUser) {            return new ModelAndView("login", "error", "用户名或密码错误。");        } else {            User user = userService.findUserByUserName(loginCommand                    .getUserName());            user.setLastIp(request.getLocalAddr());            user.setLastVisit(new Date());            userService.loginSuccess(user);            request.getSession().setAttribute("user", user);            return new ModelAndView("main");        }    }}

c,编写好控制类的代码，我们就可以测试这个控制类了，下面的代码是使用TestNg测试controller十分正确

package test.com.smart.web;import com.smart.domain.User;import com.smart.web.LoginController;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.mock.web.MockHttpServletRequest;import org.springframework.mock.web.MockHttpServletResponse;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.testng.AbstractTestNGSpringContextTests;import org.springframework.test.util.ReflectionTestUtils;import org.springframework.web.client.RestTemplate;import org.springframework.web.servlet.HandlerMapping;import org.springframework.web.servlet.ModelAndView;import org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter;import org.testng.annotations.BeforeMethod;import org.testng.annotations.Test;import static org.testng.Assert.assertEquals;import static org.testng.Assert.assertNotNull;import static org.testng.Assert.assertNull;@ContextConfiguration(locations = {"classpath:applicationContext.xml","file:d:/actionSpring/chapter/chapter1/src/main/webapp/WEB-INF/viewspace-servlet.xml"})public class LoginControllerTest extends AbstractTestNGSpringContextTests {    @Autowired    private AnnotationMethodHandlerAdapter handlerAdapter;    @Autowired    private LoginController controller;//声明Request与Response模拟对象private MockHttpServletRequest request;private MockHttpServletResponse response;//执行测试前先初始模拟对象@BeforeMethodpublic void before() {request = new MockHttpServletRequest();request.setCharacterEncoding("UTF-8");response = new MockHttpServletResponse();        request.setAttribute(HandlerMapping.INTROSPECT_TYPE_LEVEL_MAPPING, true); //Spring3.1 存在的BUG}// 测试LoginController#loginCheck()方法@Testpublic void loginCheck() throws Exception {        //测试登陆成功的情况    request.setRequestURI("/admin/loginCheck.html");request.addParameter("userName", "admin"); // 设置请求URL及参数request.addParameter("password", "123456");//向控制发起请求 ” /loginCheck.html”ModelAndView mav = handlerAdapter.handle(request, response, controller);User user = (User) request.getSession().getAttribute("user");assertNotNull(mav);assertEquals(mav.getViewName(), "main");assertNotNull(user);        request.getSession().removeAttribute("user");        //测试登陆失败的情况        request.setRequestURI("/admin/loginCheck.html");        request.addParameter("userName", "test");        request.addParameter("password", "123456");        mav = handlerAdapter.handle(request, response, controller);        user = (User) request.getSession().getAttribute("user");        assertNotNull(mav);        assertEquals(mav.getViewName(), "login");        assertNull(user);}}

注意：

1. @ContextConfiguration(locations = {"classpath:applicationContext.xml","file:d:/actionSpring/chapter/chapter1/src/main/webapp/WEB-INF/viewspace-servlet.xml"})  这个注解可以整合多个spring配置文件中"file:d:/actionSpring/chapter/chapter1/src/main/webapp/WEB-INF/viewspace-servlet.xml"表示的是文件系统的形式给出配置文件
