나는 인터넷 검색을 할 때이 질문을 접하게되었다. 나는 정확히 같은 질문을했다.
나는 (매우 많은 테스트를 거친) Maven 플러그인을 작성했습니다. 현재는 WAR 만 지원하지만 쉽게 확장 할 수 있습니다. 또한이 플러그인을 만족시키기 위해 많은 속성 집합을 유지해야하는 번거 로움을 싫어하기 때문에 실제로 콩을로드하는 것은 어렵지 않습니다.

하고, 제로 생각 자동으로 자료 해결책을 찾기 위해 기대했다 그러나 당신은 좋은 지적을합니다. 실제로 조금 생각해야 할 것 같네요. 불평. 감사. – Ickster
Gweebz,이 소스 코드를 공유 하시겠습니까? 나는 내 프로젝트에서이 JUnit 테스트를하고 싶다. –
@Cory - 나는이 코드를 찾으려고 노력할 것입니다. 제가 SVN을 살펴보아야 할 것입니다. –
