contextLoads() 테스트 실패

CoreApplicationTests 속 contextLoads() 테스트를 실행하였는데

java.lang.IllegalStateException: Failed to load ApplicationContext for [WebMergedContextConfiguration@3f9f71ff testClass = hello.core.CoreApplicationTests, locations = [], classes = [hello.core.CoreApplication], contextInitializerClasses = [], activeProfiles = [], propertySourceDescriptors = [], propertySourceProperties = ["org.springframework.boot.test.context.SpringBootTestContextBootstrapper=true"], contextCustomizers = [org.springframework.boot.test.autoconfigure.actuate.observability.ObservabilityContextCustomizerFactory$DisableObservabilityContextCustomizer@1f, org.springframework.boot.test.autoconfigure.properties.PropertyMappingContextCustomizer@0, org.springframework.boot.test.autoconfigure.web.servlet.WebDriverContextCustomizer@35aea049, org.springframework.boot.test.context.filter.ExcludeFilterContextCustomizer@3b6ddd1d, org.springframework.boot.test.json.DuplicateJsonObjectContextCustomizerFactory$DuplicateJsonObjectContextCustomizer@2f217633, org.springframework.boot.test.mock.mockito.MockitoContextCustomizer@0, org.springframework.boot.test.web.client.TestRestTemplateContextCustomizer@6fd83fc1, org.springframework.boot.test.context.SpringBootTestAnnotation@8daef27a], resourceBasePath = "src/main/webapp", contextLoader = org.springframework.boot.test.context.SpringBootContextLoader, parent = null]

이런 오류가 나면서 실패합니다. 왜 이런가요?

참고용으로 AutoAppConfig 와 AppConfig 코드 입니다.

AutoAppConfig

package hello.core.order;

import hello.core.member.MemberRepository;
import hello.core.member.MemoryMemberRepository;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.FilterType;

@Configuration
@ComponentScan(
    excludeFilters = @ComponentScan.Filter(type = FilterType.ANNOTATION, classes = Configuration.class)
)
public class AutoAppConfig {
/*
  @Bean(name = "memoryMemberRepository")
  public MemberRepository memberRepository() {
    return new MemoryMemberRepository();
  }
  */
}

AppConfig

package hello.core;

import hello.core.order.OrderServiceImpl;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class AppConfig {

    //call AppConfig.memberService
    //call AppConfig.memberRepository

    return new MemberServiceImpl(memberRepository());
  }

  @Bean

    return new MemoryMemberRepository();
  }

  @Bean
  public OrderService orderService() {
    System.out.println("call AppConfig.orderService");
    return new OrderServiceImpl(memberRepository(), discountPolicy());
  }

  @Bean
  public DiscountPolicy discountPolicy() {

  }
}
