无法在测试中自动关联依赖项

我想写一个Spring集成测试来确保 @Autowired

考试班

@RunWith(SpringRunner.class)
@DataJpaTest
@EntityScan(basePackageClasses = {ClassUnderTest.class, SomRepository.class, SomeEntity.class})
public class ClassUnderTestIT{

    @Autowired private InterfaceUnderTest cut;

    @Test public void autowires() {
        assertThat(cut).isNotNull();
    }

}

应该测试一下这个 @Service

@Service
@Transactional
public class ClassUnderTest implements InterfaceUnderTest {

    private final SomeRepository repository;

    @Autowired
    public DefaultWatchlistDataModifier(SomeRepository repository) {
        this.repository = repository;
    }

}

特别注意有线依赖关系

@Repository
@Transactional(readOnly = true)
@Scope(value = BeanDefinition.SCOPE_PROTOTYPE)
public interface SomeRepository extends JpaRepository<SomeEntity, String> {
}

然而,我得到的只是一个例外

org.springframework.beans.factory.NoSuchBeanDefinitionException:
No qualifying bean of type 'com.[...].InterfaceUnderTest' available:
expected at least 1 bean which qualifies as autowire candidate.
Dependency annotations: 
{@org.springframework.beans.factory.annotation.Autowired(required=true)}

同时,我还尝试了各种附加注释,例如 @ComponentScan @EnableJpaRepositories ... 无论我能从无数关于这个话题的问题中挖掘出什么,都是徒劳的。
