springboot03-unittest mockmvc单元测试
整个项目结构：
定义user实体类
package com.mlxs.springboot.dto; import java.util.HashMap; import java.util.Map; /** * User类描述: * * @author yangzhenlong * @since 2017/2/13 */ public class User { private int id; private String name; public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public static Map<Integer, User> buildUserList(){ Map<Integer, User> userMap = new HashMap<>(); for(int i=1; i<=5; i++){ User user = new User(); user.setId(i); user.setName("测试" + i); userMap.put(i, user); } return userMap; } }
MainApp启动类：
package com.mlxs.springboot.web; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.context.ConfigurableApplicationContext; /** * MainApp类描述: * * @author yangzhenlong * @since 2017/2/13 */ @SpringBootApplication public class MainApp { public static void main(String[] args) { ConfigurableApplicationContext context = SpringApplication.run(MainApp.class, args); /*String[] beanDefinitionNames = context.getBeanDefinitionNames(); System.out.println("-------- bean名称打印 --------"); for (String name : beanDefinitionNames) { System.out.println(name); }*/ } }
UserService接口类：
public interface UserService { /** * 查询所有用户 * @return */ Map<Integer, User> getAllUsers(); /** * 根据Id查询 * @param id * @return */ User getUserById(Integer id); /** * 更新 * @param user * @return */ User updateUserById(User user); /** * 添加 * @param user * @return */ User addUser(User user); /** * 删除 * @param id * @return */ boolean deleteUser(Integer id); }
Service实现类：
@Service public class UserServiceImpl implements UserService{ private static Map<Integer, User> userMap = User.buildUserList(); /** * 查询所有用户 * @return */ public Map<Integer, User> getAllUsers(){ return userMap; } /** * 根据Id查询 * @param id * @return */ public User getUserById(Integer id){ return userMap.get(id); } /** * 更新 * @param user * @return */ public User updateUserById(User user){ if(null == userMap.get(user.getId())){ throw new RuntimeException("用户不存在"); } userMap.put(user.getId(), user); return user; } /** * 添加 * @param user * @return */ public User addUser(User user){ if(null != userMap.get(user.getId())){ throw new RuntimeException("用户已存在"); } userMap.put(user.getId(), user); return user; } /** * 删除 * @param id * @return */ public boolean deleteUser(Integer id){ if(null == userMap.get(id)){ throw new RuntimeException("用户不存在"); } userMap.remove(id); return true; } }
rest接口类UserController：
@RestController() @RequestMapping("/") public class UserController { private static Map<Integer, User> userMap = User.buildUserList(); /** * 查询所有用户 * @return */ @RequestMapping(value = "/user", method = RequestMethod.GET) public Map<Integer, User> getAllUsers(){ return userMap; } /** * 根据Id查询 * @param id * @return */ @RequestMapping(value = "/user/{id}", method = RequestMethod.GET) public User getUserById(Integer id){ return userMap.get(id); } /** * 更新 * @param user * @return */ @RequestMapping(value = "/user", method = RequestMethod.PUT) public User updateUserById(User user){ if(null == userMap.get(user.getId())){ throw new RuntimeException("用户不存在"); } userMap.put(user.getId(), user); return user; } /** * 添加 * @param user * @return */ @RequestMapping(value = "/user", method = RequestMethod.POST) public User addUser(User user){ if(null != userMap.get(user.getId())){ throw new RuntimeException("用户已存在"); } userMap.put(user.getId(), user); return user; } /** * 删除 * @param id * @return */ @RequestMapping(value = "/user", method = RequestMethod.DELETE) public String deleteUser(Integer id){ if(null == userMap.get(id)){ throw new RuntimeException("用户不存在"); } userMap.remove(id); return "delete success"; } }
1.mockmvc针对service的单元测试：
UserServiceTest
import com.fasterxml.jackson.core.JsonProcessingException; import com.fasterxml.jackson.databind.ObjectMapper; import com.mlxs.springboot.dto.User; import com.mlxs.springboot.web.MainApp; import com.mlxs.springboot.web.UserService; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.SpringApplicationConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; /** * UserWebTest类描述: * * @author yangzhenlong * @since 2017/2/13 */ @RunWith(SpringJUnit4ClassRunner.class) @SpringApplicationConfiguration(MainApp.class) public class UserServiceTest { @Autowired private UserService userService; @Autowired private ObjectMapper om; @Test public void testAll() throws JsonProcessingException { this.list(); this.add(); this.update(); this.delete(); } @Test public void list() throws JsonProcessingException { System.out.println("\n----------查询----------"); this.print(userService.getAllUsers()); } @Test public void add(){ System.out.println("\n----------添加----------"); User add = new User(); add.setId(10); add.setName("这是新添加"); userService.addUser(add); this.print(userService.getAllUsers()); } @Test public void update(){ System.out.println("\n----------更新----------"); User user = userService.getUserById(2); user.setName("测试222"); userService.updateUserById(user); this.print(userService.getAllUsers()); } @Test public void delete(){ System.out.println("\n----------删除----------"); userService.deleteUser(3); this.print(userService.getAllUsers()); } private void print(Object obj){ try { System.out.println(om.writeValueAsString(obj)); } catch (JsonProcessingException e) { e.printStackTrace(); } } }
执行testAll()方法结果：
2.mockmvc针对rest接口类的测试：
UserWebTest：
import com.mlxs.springboot.web.UserController; import org.hamcrest.Matchers; import org.junit.Before; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.boot.test.SpringApplicationConfiguration; import org.springframework.mock.web.MockServletContext; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import org.springframework.test.context.web.WebAppConfiguration; import org.springframework.test.web.servlet.MockMvc; import org.springframework.test.web.servlet.request.MockMvcRequestBuilders; import org.springframework.test.web.servlet.result.MockMvcResultMatchers; import org.springframework.test.web.servlet.setup.MockMvcBuilders; /** * UserWebTest类描述: * * @author yangzhenlong * @since 2017/2/13 */ @RunWith(SpringJUnit4ClassRunner.class) @SpringApplicationConfiguration(MockServletContext.class) @WebAppConfiguration //启动一个真实web服务，然后调用Controller的Rest API，待单元测试完成之后再将web服务停掉 public class UserWebTest { private MockMvc mockMvc; @Before public void setMockMvc(){ mockMvc = MockMvcBuilders.standaloneSetup(new UserController()).build();//设置要mock的Controller类，可以是多个 } @Test public void testAll() throws Exception { //1.查询 String queryResult = mockMvc.perform(MockMvcRequestBuilders.get("/user")) .andExpect(MockMvcResultMatchers.status().isOk()) .andExpect(MockMvcResultMatchers.content().string(Matchers.containsString("id"))) .andReturn().getResponse().getContentAsString(); System.out.println("----------查询----------\n" + queryResult); //2.添加 String addResult = mockMvc.perform(MockMvcRequestBuilders.post("/user").param("id", "10").param("name", "新添加")) .andReturn() .getResponse() .getContentAsString(); System.out.println("----------添加----------\n" + addResult); //3.更新 String updateResult = mockMvc.perform(MockMvcRequestBuilders.put("/user").param("id", "3").param("name", "更新333")) .andReturn() .getResponse() .getContentAsString(); System.out.println("----------更新----------\n" + updateResult); //4.删除 String deleteResult = mockMvc.perform(MockMvcRequestBuilders.delete("/user").param("id", "1")) .andReturn() .getResponse() .getContentAsString(); System.out.println("----------删除----------\n" + deleteResult); } }
执行testAll()方法后结果：
