인프런 커뮤니티 질문&답변

안녕하세요~

아래와 같이 계속 오류가 발생하고 있는데,,, 해결 방법이 있을까요??

org.junit.runners.model.InvalidTestClassError: Invalid test class 'jpabook.jpashop.MemberRepositoryTest':

  1. The class jpabook.jpashop.MemberRepositoryTest is not public.

  2. Test class should have exactly one public constructor

MemberRepositoryTest.java

package jpabook.jpashop;

import org.assertj.core.api.Assertions;
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.annotation.Rollback;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.transaction.annotation.Transactional;

import javax.persistence.EntityManager;

@RunWith(SpringRunner.class)
@SpringBootTest
class MemberRepositoryTest {

    @Autowired MemberRepository memberRepository;

    @Test
    @Transactional
    @Rollback(false)
    public void testMember() throws Exception{
        //given
        Member member = new Member();
        member.setUsername("memberA");

        //when
        Long savedId = memberRepository.save(member);
        Member findMember = memberRepository.find(savedId);

        //then
        Assertions.assertThat(findMember.getId()).isEqualTo(member.getId());
        Assertions.assertThat(findMember.getUsername()).isEqualTo(member.getUsername());

    }


}
