인프런 커뮤니티 질문&답변

안녕하세요. 강의 잘 듣고있습니다 :)

allopen 관련 질문이 하나 있는데요.

이전 강의에서 UserService를 코틀린으로 리팩토링했었는데 해당 과정부터 이번 BookService 리팩토링 강의까지 allopen 관련 에러가 발생하는 것 같습니다.

Failed to resolve parameter [com.group.libraryapp.domain.user.UserRepository userRepository] in constructor [public com.group.libraryapp.service.user.UserServiceTest(com.group.libraryapp.domain.user.UserRepository,com.group.libraryapp.service.user.UserService)]: Failed to load ApplicationContext
org.junit.jupiter.api.extension.ParameterResolutionException: Failed to resolve parameter [com.group.libraryapp.domain.user.UserRepository userRepository] in constructor [public com.group.libraryapp.service.user.UserServiceTest(com.group.libraryapp.domain.user.UserRepository,com.group.libraryapp.service.user.UserService)]: Failed to load ApplicationContext

리팩토링을 완료하고 테스트 코드를 실행시켜보면 위와 같은 에러가 발생합니다.

하지만 UserService의 클래스와 메소드들에 open을 붙여주면 정상적으로 돌아가더라구요.

tasks.named('test') {
    useJUnitPlatform()

compileKotlin {
    kotlinOptions {

    }
}

compileTestKotlin {
    kotlinOptions {
        jvmTarget = "11"
    }
}

현재 제 build.gradle 파일도 같이 첨부합니다.

감사합니다 :)
