소프트웨어의 테스트는 소프트웨어의 품질결정을 위한 필수항목으로서 체계적인 방법과 절차에 따라서 진행되어야 한다. 많은 노력으로 개발되고 판매되는 소프트웨어서도 오류가 발견되며, 발견된 오류의 절반이상이 개발과정에서 발생 하므로 개발단계부터 결함으로 제거할 수 있는 소프트 테스트가 필요하다. 소프트웨어의 테스트는 소프트웨어가 좋은가를 검증하는 것이 아니라 요구된 명세서의 구현과 구현된 소프트웨어에 결함이 있는가를 찾는 행위이며, 소프트웨어 개발에 최종적인 검토이다. 본 연구에서는 객체지향 소프트웨어의 품질을 향상시키기 위하여 클래스 기반의 단위테스트 수행 시 "Error Seeding" 전략을 통한 동적테스트를 수행하고, 테스팅 과정에 대한 관리 및 성능 테스트를 제공하는 도구를 제안한다. 본 프레임워크는 테스트 유형을 테스트 수행자가 결정하고 테스트를 수행하므로 결과판독이 정확하고 빠른 장점이 있다.

인터넷의 급속한 보급과 웹 인터페이스를 기반으로 하는 사내 전산 시스템인 인트라넷(Intranet) 어플리케이션 개발이 보편화되고 있다. 그러나 인트라넷 도입에는 기존 시스템 및 데이터베이스와의 연동, 사내의 고유한 업무흐름(Workflow), 성능 및 보안 요구사항이 있어 패키지 형태의 인트라넷 제품은 그 확장성와 적용성에 한계를 가지고 있다. 본 논문에서는 인트라넷 어플리케이션 개발에 재사용될 수 있는 공통 기능 모듈들을 재사용 신기술인 '객체지향 프레임워크' 방식을 적용함으로써, 기업에서 인트라넷 어플리케이션을 개발할 때에 비용이나 기간을 단축하여 높은 효율을 갖고자 한다.

An object-oriented framework supports efficient component-based software development by providing a flexible architecture that can be decomposed into easily modifiable and composable classes. Object-oriented frameworks require thorough testing as they are intended to be reused repeatedly In developing numerous applications. Furthermore, additional testing is needed each time the framework is modified and extended for reuse. To test a framework, it must be instantiated into a complete, executable system. It is, however, practically impossible to test a framework exhaustively against all kinds of framework instantiations, as possible systems into which a framework can be configured are infinitely diverse. If we can classify possible configurations of a framework into a finite number of groups so that all configurations of a group have the same structural or behavioral characteristics, we can effectively cover all significant test cases for the framework testing by choosing a representative configuration from each group. This paper proposes a systematic method of classifying object structures of a framework hotspot and extracting structural test patterns from them. This paper also presents how we can select an instance of object structure from each extracted test pattern for use in the frameworks hotspot testing. This method is useful for selection of optimal test cases and systematic construction of executable test target.

Recently, OOM(Object-Oriented Method) access method which begins to apply to software development is emphasizing development cost and time reduction through independent software reuse. But because of planning to the exclusion of the lack of knowledge and expansion or performance for development technology many problems are coming out. Therefore, this thesis suggests Effective Object-Oriented Modeling methods considering the plan for higher productivity enhancement of software in the software development life cycle. Effective Object-Oriented Modeling method includes, methods, Use Case modeling methods, Analysis Modeling methods, Design Modeling methods and others. This thesis suggests Framework model method read in characteristics as follows. First, suggestion about effective object-oriented standard model development, Second, retrenchment of software development or maintenance cost, Third, solution about uncertain problems of projects in line with the application of new technology.

서비스의 중단 없이 소프트웨어를 동적으로 업그레이드하고 확장하기 위해서는 객체지향 소프트웨어의 작은 단위인 모듈 즉, 객체를 동적으로 교체할 수 있는 구조가 필요하다. 특히 컴퓨터통신 네트워크 분야에서는 서로 영역에 넓게 퍼져 있을 경우 특별히 복잡한 구조를 가지고 된다. 본 논문에서는 이러한 객체 핫 스와핑을 가능하게 방법들을 비교분석 하고 가장 효율적인 방법을 사용해서 객체 핫 스와핑이 가능하게 하는 프레임워크를 설계 및 구현하였다.

This paper proposes for practical engineers a lightweight modeling and simulation environment for continuous system models specified in ordinary differential equations, which are time-domain specification of such systems. We propose a block-oriented specification formalism that has two levels: one for atomic behavior and the other the structure of models. Also we provide with a simulation framework, called BlockSim++, which make models specified in the block-oriented formalism be easily translated in object-oriented program that runs with the proposed simulation framework. The proposed formalism and framework has advantage of reuse such that it can be easily integrated into application programs and heterogeneous simulators. We illustrates the usefulness of the proposed framework by a simple hybrid modeling simulation example.

This paper presents a UML CASE tool for collaboration work between remote place. It configured functions to support collaboration work and it applied framework concept to increase extension and reusability. It also constructed UML CASE tool based on framework. It result in not only reflecting various stakeholder's opinions but it also contributing to integrated and consistent modeling.

Due to the classes in object-orientation, which are too detailed and specific, their reusability can be decreased. Components, considered to be more coarse-grained compared to objects, help maintain software complexity effectively and facilitate software reuse. Furthermore, component technology becomes essential by the appearance of the new frameworks, such as MDA, SOA, etc. Consequently, it is necessary to reengineer an existing object-oriented system into a component-based system suitable to those new environments. In this paper, we propose a model-based quantitative reengineering methodology to identify components from object-oriented systems. We expand system model and process, which are defined in our prior work, more formally and precisely. A system model, constructed from object-oriented system, is used to extract and refine components in quantitative ways. We develop a supporting tool and show effectiveness of the methodology through applying it to an existing object-oriented system.
