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：
