[스프링부트/웹 애플리케이션 개발]회원 기능 테스트

테스트 요구사항

- 회원가입 성공

- 회원가입 할 때 같은 이름이 있으면 예외 발생

 

 

 

회원가입 test

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

    @Autowired MemberService memberService;
    @Autowired MemberRepository memberRepository;

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

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

        //then
        assertEquals(member, memberRepository.findOne(saveId));
    }
}

- transacrional  > insert문 확인 할 수 없음

 

 

insert문 확인하는 방법 1. @Rollback(false) 추가

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

    @Autowired MemberService memberService;
    @Autowired MemberRepository memberRepository;

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

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

        //then
        assertEquals(member, memberRepository.findOne(saveId));
    }
}

 

insert문 확인하는 방법 2. em 코드 추가

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

    @Autowired MemberService memberService;
    @Autowired MemberRepository memberRepository;

    @Autowired EntityManager em;

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

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

        //then
        em.flush();
        assertEquals(member, memberRepository.findOne(saveId));
    }
}

- flush가 db에 쿼리를 날리고 테스트가 끝날 때 @Transactional이 rollback

- 테스트할 때 rollback이 필요한 이유는 테스트를 반복해야 하기 때문에 데이터가 남으면 안 됨

 

 

 

회원중복 test

@Test(expected = IllegalStateException.class)
    public void 중복_회원_예외() 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.");
    }

 

 

 

MemberServiceTest

package jpabook.jpashop.service;

import jpabook.jpashop.domain.Member;
import jpabook.jpashop.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.assertEquals;
import static org.junit.Assert.fail;

@RunWith(SpringRunner.class)
@SpringBootTest
@Transactional
public class MemberServiceTest {
    @Autowired MemberService memberService;
    @Autowired MemberRepository memberRepository;

    @Test
    //@Rollback(false) > insert문 확인 방법1.
    public void 회원가입() throws Exception {
        //given
        Member member = new Member();
        member.setName("kim");

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

        //then
        //em.flush();
        assertEquals(member, memberRepository.findOne(saveId));
    }

    @Test(expected = IllegalStateException.class)
    public void 중복_회원_예외() 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.");
    }
}

 

 

 

- 어노테이션 의미

@RunWith(SpringRunner.class) : Junit 실행하면서 스프링도 함께 실행

@SpringBootTest : 스프링부트를 띄운 상태로 테스트

@Transactional : 롤백

 

 

 

- 테스트케이스 작성 참고

(http://martinfowler.com/bliki/GivenWhenThen.html)

 

 

 

- 테스트를 완전히 격리된 환경에서 하도록 설정 

1) test에 resources 디렉토리 추가

2) resources에 application.yml 복사 붙여 넣기

3) application.yml > spring > datasource > url 수정

spring:
  datasource:
  url: jdbc:h2:mem:testdb
  username: sa
  password:
  driver-class-name: org.h2.Driver

 

참고. 스프링부트에서는 별도의 설정이 없으면 메모리 모드로 돌린다. 따라서 application.yml의 코드 생략 가능

spring:
#  datasource:
#    url: jdbc:h2:mem:testdb
#    username: sa
#    password:
#    driver-class-name: org.h2.Driver

#  jpa:
#    hibernate:
#      ddl-auto: create-drop
#    properties:
#      hibernate:
#        show_sql: true
#        format_sql: true

logging:
  level:
    org.hibernate.SQL: debug
    org.hibernate.type: trace
