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
