/**
 * TestCase Name : HttpInvokerSpringSupportTest <br>
 * <br>
 * [Description] : Spring에서 제공하는 기능인 Http Invoker 기반의 Movie 서비스를 구현하여 
 *                 서비스의 기능을 테스트할 수 있는 시나리오들을 정의한 TestCase이다. <br>
 * [Characteristic]
 * <li>RMI와 같이 자바의 표준 직렬화 매커니즘 사용</li>
 * <li>Hessian/Burlap과 같이 HTTP 기반의 Remoting 수행</li>
 * <li>제약 사항 존재-Spring에서만 제공하는 Remoting 기술로 클라이언트와 원격 서비스 모두 Spring 어플리케이션이어야 함</li>
 * <li>서버 구현: Spring에서 제공하는 org.springframework.remoting.httpinvoker.HttpInvokerServiceExporter 클래스를 이용하여 
 *               손쉽게 일반 Spring Bean으로 작성된 서비스를 HttpInvoker Service로 노출, 
 *               Spring MVC를 사용하여 HTTP 기반 HttpInvoker 컨트롤러 설정</li>
 * <li>클라이언트 구현: Spring에서 제공하는 org.springframework.remoting.httpinvoker.HttpInvokerProxyFactoryBean 클래스 이용</li>
 * <br>
 * [Assumption]
 * <li>-서버 : JettyServer 사용, Spring 설정 파일 이용</li>
 * <li>-클라이언트 : RemotingSpringTestCase 사용, Spring 설정 파일 이용</li>
 * <br>
 * [Main Flow]
 * <li>#-1 Positive Case : List 형태로 전체 목록을 조회한다.</li>
 * <li>#-2 Positive Case : Map 형태로 전체 목록을 조회한다.</li>
 * <li>#-3 Positive Case : Movie를 조회한다.</li>
 * <li>#-4 Positive Case : 신규 Movie를 생성한다.</li>
 * <li>#-5 Positive Case : Movie 정보를 변경한다.</li>
 * <li>#-6 Positive Case : Movie를 삭제한다.</li>
