이 시험 자체에 근본적인 경쟁 조건과 관련이있을 것 같지 않지만, 테스트를 괴짜 원인 : 나는 다음과 같은 오류를 참조하십시오. 누구든지이 버그에 대한 해결 방법이 있습니까?

Answer 1

검색 서비스 테스트 구성없이 테스트에서 Search Service Indexer를 사용했기 때문입니다. 문제를 해결하기 위해 올바른 구성을 추가하면 문제가 해결됩니다.

private final LocalServiceTestHelper helper = 
     new LocalServiceTestHelper(
       new LocalSearchServiceTestConfig()); 

@Before 
public void setUp() throws Exception { 
    helper.setUp(); 
} 

@After 
public void tearDown() { 
    helper.tearDown(); 
}
