Spring 핵심 원리 - 주문과 할인 도메인 테스트

1. 직접 main 메소드로 테스트 해보기 (JUnit 사용하지 않음)

package Goat.core;

import Goat.core.member.Grade;
import Goat.core.member.Member;
import Goat.core.member.MemberService;
import Goat.core.member.MemberServiceImpl;
import Goat.core.order.Order;
import Goat.core.order.OrderService;
import Goat.core.order.OrderServiceImpl;

public class OrderApp {
    public static void main(String[] args) {
        MemberService memberService = new MemberServiceImpl();
        OrderService orderService = new OrderServiceImpl();

        Long memberId = 1L;
        Member member = new Member(memberId,"Goat", Grade.VIP);
        memberService.join(member);

        Order order = orderService.createOrder(memberId,"itemA",10000);
        System.out.println("order = "+order);

    }
}

2. JUnit 사용

package Goat.core.order;

import Goat.core.member.Grade;
import Goat.core.member.Member;
import Goat.core.member.MemberService;
import Goat.core.member.MemberServiceImpl;
import org.assertj.core.api.Assertions;
import org.junit.jupiter.api.Test;

public class OrderServiceTest {

    MemberService memberService = new MemberServiceImpl();
    OrderService orderService = new OrderServiceImpl();

    @Test
    void createOrder(){
        Long memberId = 1L;
        Member member = new Member(memberId, "Goat", Grade.VIP);
        memberService.join(member);

        Order order = orderService.createOrder(memberId, "itemA", 10000);

        Assertions.assertThat(order.getDiscountPrice()).isEqualTo(1000);
    }
}
