DataJpaTest 오류: `Property 'spring.profiles.include' imported from location 'class path resource [application-test.properties]' is invalid in a profile specific resource [origin: class path resource [application-test.properties]`

이전 노션 블로그의 DataJpaTest 오류: `Property 'spring.profiles.include' imported from location 'class path resource [application-test.properties]'... (2023.09.12)로부터 마이그레이션된 글입니다.

schema.sql, data.sql 을 @Sql(location = {}) 으로 연결해서 스키마 생성하고 데이터 넣는 방법 절대 추천하지 않음. 로컬에서 Github actions 인스턴스까지 계속 문제 발생함.

무조건 프로젝트/src/test/resources/ 안에 테스트용 application-test.yml 생성하고, h2 설정하는 것을 추천

@ActiveProfiles("test")
@DataJpaTest
@TestPropertySource(locations = {"classpath:application-test.yml"})
@AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)
class CustomerRepositoryTest {

}

yml이 아니라 properties 확장자 사용하면 발생하는 오류

application-test.properties 가 아니라, applicaiton-test.yml 을 설정해야 한다.
