Failed to load ApplicationContext 오류 해결 방법

[질문 내용]
회원기능 테스트에서 분명 강사님이 하신거랑 똑같이 따라했고 오타가 있을까하여 강의 소스 코드도 점검하고 복사붙여넣기 까지 했는데 같은 오류가 계속 반복해서 발생합니다..

오류:
java.lang.IllegalStateException: Failed to load ApplicationContext for [WebMergedContextConfiguration@f849027 testClass = jpabook.jpashop.service.MemberServiceTest, locations = [], classes = [jpabook.jpashop.JpashopApplication], contextInitializerClasses = [], activeProfiles = [], propertySourceDescriptors = [], propertySourceProperties = ["org.springframework.boot.test.context.SpringBootTestContextBootstrapper=true"], contextCustomizers = [org.springframework.boot.test.autoconfigure.actuate.observability.ObservabilityContextCustomizerFactory$DisableObservabilityContextCustomizer@1f, org.springframework.boot.test.autoconfigure.properties.PropertyMappingContextCustomizer@0, org.springframework.boot.test.autoconfigure.web.servlet.WebDriverContextCustomizer@5c2375a9, org.springframework.boot.test.context.filter.ExcludeFilterContextCustomizer@492691d7, org.springframework.boot.test.json.DuplicateJsonObjectContextCustomizerFactory$DuplicateJsonObjectContextCustomizer@67545b57, org.springframework.boot.test.mock.mockito.MockitoContextCustomizer@0, org.springframework.boot.test.web.client.TestRestTemplateContextCustomizer@1c93f6e1, org.springframework.boot.test.context.SpringBootTestAnnotation@5495e57], resourceBasePath = "src/main/webapp", contextLoader = org.springframework.boot.test.context.SpringBootContextLoader, parent = null]

이 링크와 같은 문제인 것 같은데 h2를 재설치 해도 해결 되지 않네요 ㅜㅜ 도움 받을 수 있을까요?
