Spring boot 시작하기 - 4강(테스트)

테스트 케이스를 만들고 테스트를 해보겠습니다. 아래와 같이 테스트 패키지-hello.hellospring 패키지 아래에 repository패키지와 MemoryMemberRepositoryTest클래스를 구성합니다.

1. MemoryMemberRepositoryTest클래스

package hello.hellospring.repository;

import hello.hellospring.domain.Member;
import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;
import java.util.List;

import static org.assertj.core.api.Assertions.assertThat;

public class MemoryMemberRepositoryTest {

    MemoryMemberRepository repository = new MemoryMemberRepository();

    @AfterEach
    public void afterEach(){
        repository.clearStore();
    }

    @Test
    public void save(){
        Member member = new Member();
        member.setName("spring");

        repository.save(member);

        Member result = repository.findById(member.getId()).get();
        //Assertions.assertEquals(member, null); (기대값, 실제값)
        assertThat(member).isEqualTo(result); //(기대값, 실제값)

    }

    @Test
    public void indByName(){
        Member member1 = new Member();
        member1.setName("spring1");
        repository.save(member1);

        Member member2 = new Member();
        member2.setName("spring2");
        repository.save(member2);

        Member result = repository.findByName("spring1").get();

        assertThat(result).isEqualTo(member1);
    }

    @Test
    public void findAll(){
        Member member1 = new Member();
        member1.setName("spring1");
        repository.save(member1);

        Member member2 = new Member();
        member2.setName("spring2");
        repository.save(member2);

        List<Member> result = repository.findAll();

        assertThat(result.size()).isEqualTo(2);
    }
}
