0. 구성도

 

1. WelcomeController 클래스를 생성 후 코드입력

package kr.com.cyh.RRS.interfaces;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class WelcomeController {

    @GetMapping("/")
    public String hello() {
        return "Hello, World!!";
    }
}

 

2. RestaurantReservationSystemApplication 을 실행

package kr.com.cyh.RRS;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class RestaurantReservationSystemApplication {

	public static void main(String[] args) {
		SpringApplication.run(RestaurantReservationSystemApplication.class, args);
	}

}

4. RestaurantController 추가

package kr.com.cyh.RRS.interfaces;

import kr.com.cyh.RRS.domain.Restaurant;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.ArrayList;
import java.util.List;

@RestController
public class RestaurantController {

    @GetMapping("/restaurants")
    public List<Restaurant> list() {
        List<Restaurant> restaurants = new ArrayList<>();

        Restaurant restaurant = new Restaurant("Bob zip", "Seoul", 1004L);

        restaurants.add(restaurant);

        return restaurants;
    }
}

 

5. Restaurant 추가

package kr.com.cyh.RRS.domain;

import org.springframework.web.bind.annotation.RestController;

//@RestController
public class Restaurant {

    private final String address;
    private final String name;
    private final long id;

    public Restaurant(String name, String address, long id) {
        this.name = name;
        this.address = address;
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public String getAddress() {
        return address;
    }

    public String getInformation() {
        return name + " in " + address;
    }

    public Long getId() {
        return id;
    }
}

 

6. RestaurantControllerTest 추가 및 단위테스트 실행

package kr.com.cyh.RRS.interfaces;

import org.junit.jupiter.api.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import sun.tools.jconsole.JConsole;

import static org.hamcrest.Matchers.containsString;
import static org.junit.Assert.*;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

@RunWith(SpringRunner.class)
@WebMvcTest(RestaurantController.class)
public class RestaurantControllerTest {

    @Autowired
    private MockMvc mvc;

    @Test
    public void test() throws Exception {
        mvc.perform(get("/restaurants"))
                .andExpect(status().isOk())
                .andExpect(content().json(  //json array
                        "[{\"address\":\"Seoul\",\"name\":\"Bob zip\",\"id\":1004,\"information\":\"Bob zip in Seoul\"}]"
                ));
//                .andExpect(content().json(
//                        //json object
//                        "{'data':[{'useRegEx':'false','hosts':'v2v2v2'}]}"
//                ));
    }

    @Test
    public void list() throws Exception {
        mvc.perform(get("/restaurants"))
                .andExpect(status().isOk())
                .andExpect(content().string(
                        containsString("\"id\":1004")
                ))
                .andExpect(content().string(
                    containsString("\"name\":\"Bob zip\"")
                ));
    }
}

 

7. RestaurantTests 추가 및 단위테스트 실행

package kr.com.cyh.RRS.domain;


import org.junit.jupiter.api.Test;

import static org.hamcrest.core.Is.is;
import static org.junit.Assert.*;

public class RestaurantTests {
    @Test
    public void creation() {
        Restaurant restaurant = new Restaurant("Bob zip", "Seoul", 1004L);

        assertThat(restaurant.getId(), is(1004L));
        assertThat(restaurant.getName(), is("Bob zip"));
        assertThat(restaurant.getAddress(), is("Seoul"));
    }

    @Test
    public void information() {
        Restaurant restaurant = new Restaurant("Bob zip", "Seoul", 1004L);

        assertThat(restaurant.getInformation(), is("Bob zip in Seoul"));
    }
}
