spring - SpringBoot JPA テスト Bean がコンテキストにない

Question

私はこれを理解することができません..何らかの理由で、Spring Junit が私の Bean をコンテキストに追加していません。ウェルプしてください!!

原因: org.springframework.beans.factory.NoSuchBeanDefinitionException: タイプ 'com.api.demo.store.FileStorage' の適格な Bean がありません: autowire 候補として適格な Bean が少なくとも 1 つ必要です。依存関係の注釈: {@org.springframework.beans.factory.annotation.Autowired(required=true), @org.springframework.beans.factory.annotation.Qualifier(value=com.api.demo.store.FileStorageMemDB)} at org .springframework.beans.factory.support.DefaultListableBeanFactory.raiseNoMatchingBeanFound(DefaultListableBeanFactory.java:1493) at org.springframework.beans.factory.support.DefaultListableBeanFactory.doResolveDependency(DefaultListableBeanFactory.java:1104) at org.springframework.beans.factory.support org.springframework.beans の .DefaultListableBeanFactory.resolveDependency(DefaultListableBeanFactory.java:1066)。

       entityManager.persist(fileInfo);
            fileStorage.retrieveAllFiles();

    }
}
