Spring Test

---

1. Spring Boot 테스트 기능 소개

   • Spring Boot Test by ToastMeetup

2. Spring Boot 테스트 관련 Use-Case

   • test-driven-spring-boot

3. Spring Boot EmbeddedDatabase 설정 시 빈 등록 샘플 코드

   • API Reference : https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/jdbc/datasource/embedded/EmbeddedDatabaseBuilder.html

     private DataSource dataSource() {
         EmbeddedDatabaseBuilder builder = new EmbeddedDatabaseBuilder();
         EmbeddedDatabase db = builder
             .setType(EmbeddedDatabaseType.H2)
             .setName("testdb;DATABASE_TO_UPPER=false;MODE=Oracle")
             .addScript("schema.sql")
             .addScript("data.sql")
             .build();
         return db;
     }

4. @DataJpaTest을 사용한 DataJpa 테스트 예제 코드
   • @DataJPATest with Spring Boot
5. JpaVendorAdapter 인터페이스를 구현 객체를 @Bean으로 동록하여 EntityManagerFactoryBean 등록 예제 코드
   • 테스트 내장 디비 설정 시 사용.
