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 @BeforeMethod public 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 @Test public 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：

@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
