WebEnvironment에서 springBootTest 주석을 사용할 때 NullPointerException이 발생했습니다.

Question

spring-boot 1.4.0.RELEASE을 사용하고 있습니다. 여기에 (스택 아래 추적)

그러나, 나는 webEnvironment= WebEnvironment.RANDOM_PORT을 제거하면 내 테스트 클래스

나는 (지금 아무것도 안하지만), 테스트에 의한 NullpointerException에 시작 실패이 테스트를 실행

@RunWith(SpringRunner.class) 
@SpringBootTest(webEnvironment= WebEnvironment.RANDOM_PORT) 
@WebAppConfiguration 
public class ApplicationTests { 

    @Test 
    public void contextLoads() { 
    } 

} 

입니다, 모든 것이 좋아 보인다.

당신은 봄 부팅 1.4의 테스트를 지원 @WebAppConfiguration 필요하지 않습니다.

그래서 단지 @WebAppConfiguration을 삭제 한 다음 ...

• 당신은이 WebApplicationContext 조롱하려는 경우 - 예를 들어, MockMvc를 사용하는 - (WebEnvironment.MOCK입니다) 기본 webEnvironment와 @SpringBootTest를 사용합니다.
• 당신은 당신의 웹 애플리케이션이 실제로 임베디드 서블릿 컨테이너에 배포하려는 경우 - 예를 들어, TestRestTemplate와 테스트 - @SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT) 또는 @SpringBootTest(webEnvironment = WebEnvironment.DEFINED_PORT)
