[Spring JPA 실습 #3] 회원 기능 테스트

package com.jpabook.service;

import com.jpabook.domain.Member;
import com.jpabook.repository.MemberRepository;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.transaction.annotation.Transactional;

import static org.junit.Assert.*;

@RunWith(SpringRunner.class)
@SpringBootTest
@Transactional
public class MemberServiceTest {

    @Autowired MemberService memberService;
    @Autowired MemberRepository memberRepository;

    //회원가입
    @Test
    public void save() throws Exception { 
        //given
        Member member = new Member();
        member.setName("kim");

        //when
        Long savedId = memberService.join(member);

        //then : db에 저장한거와 해당 member와 같나 체크
        assertEquals(member, memberRepository.findOne(savedId));
    }
    
    //중복회원 예외
    @Test
    public void duplicate() throws Exception {
        
    }
    

}

실행해서 console 쿼리를 보면 insert문이 날라가지 않는다.

그 이유는 테스트케이스에 @Transactional가 붙으면 기본적으로 롤백을 하기 때문에 insert문이 날라가지 않는다.

insert문을 보기위해서는 해당 케이스에 @Rollback(value = false)을 붙이면 된다.

//회원가입
    @Test
    @Rollback(value = false)
    public void save() throws Exception { 
        //given
        Member member = new Member();
        member.setName("kim");

        //when
        Long savedId = memberService.join(member);

        //then : db에 저장한거와 해당 member와 같나 체크
        assertEquals(member, memberRepository.findOne(savedId));
    }

 

다른방법으로

아래와 같이 @Autowired EntityManager em; 를 추가해서 em.flush()를 날려준다.

@RunWith(SpringRunner.class)
@SpringBootTest
@Transactional
public class MemberServiceTest {

    @Autowired MemberService memberService;
    @Autowired MemberRepository memberRepository;
    @Autowired EntityManager em;
    

    //회원가입
    @Test
    public void save() throws Exception { 
        //given
        Member member = new Member();
        member.setName("kim");

        //when
        Long savedId = memberService.join(member);

        //then : db에 저장한거와 해당 member와 같나 체크
        em.flush(); //db에 강제로 쿼리를 날린다.
        assertEquals(member, memberRepository.findOne(savedId));
    }
}

 

2. 중복회원 예외 테스트

//중복회원 예외
    @Test(expected = IllegalStateException.class)
    public void duplicate() throws Exception {
        //given
        Member member1 = new Member();
        member1.setName("kim");

        Member member2 = new Member();
        member2.setName("kim");

        //when
        memberService.join(member1);
        memberService.join(member2); //예외가 발생해야 한다!
                
        //then
        fail("예외가 발생해야 한다");
    }
