Agile development is mentioned a lot by developers these days. XP or Scrum is one of the popular development processes, and it says that unit test automation would drive an agile development successful. The success of unit test automation depends on how well to compare an execution result to its own expected result. that is why this paper focuses on the comparison part. This paper introduces how to build test codes for unit testing, and then concludes with mentioning two considerations of unit testing automation. First, test codes for void-typed methods need Mock Framework to monitor their behavior. Second, the comparison of execution results and expected results is hard to implement in case of testing void-typed methods. We check every sentences of a test path to decide if the testing is fail or pass.

ECU(Electric Control Unit) on the important features of the vehicle is equipped, ECU between sending and receiving messages is connected to one of the internal network(CAN BUS), but this network easily accessible from the outside and not intended to be able to receive attacks from an attacker, In this regard, the development of tools that can be used in order to verify the possibility of attacks on attacks from outside, However, the time costs incurred for developing tools and time to analyze from actual car for CAN messages to be used in the attack to find. In this paper, we want to solve it, propose a method to generate test cases required for the attack is publicly available tool called Sulley and it explains how to find the CAN messages to be used in the attack. Sulley add the CAN messages data generated library files in provided library file and than Sulley execute that make define and execute file conform to the CAN communication preferences and create message rules. Experiments performed by the proposed methodology is applied to the actual car and result, test cases generated by the CAN messages fuzzing through Sulley send in the car and as a result without a separate tool developed was operating the car.

Distributed systems are collection of physically distributed computers linked by a network. General use of wired/wireless Internet enables users to make use of distributed service anytime and anywhere. The explosive growth of distributed services strongly requires functional verification of services as well as verification of non-functional elements such as service quality. In order to verify distributed services it is necessary to build a test environment for distributed systems. Because, however, distributed systems are composed of physically distributed nodes, efforts to construct a test environment are required more than those in a test environment for a monolithic system. In this paper we propose a test framework to verify functional and non-functional features of distributed systems. The suggested framework automatically generates test cases through the message sequence charts, and includes a test driver composed of the virtual nodes which can simulate the physically distributed nodes. The test result can be checked easily through the various graphs and the graphical user interface (GUI). The test framework can reduce testing efforts for a distributed system and can enhance the reliability of the system.

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.

Web Applications are rapidly increasing and the structure becomes very complicated. However, when users explore such complex Web applications, they cannot often grasp the current location and get the information that they want. Therefore, a novel approach to model the navigation of Web application contents is required. In this study, a framework has been presented for modeling adaptive context-based contents navigation of Web applications. The framework performs activities including navigation analysis, navigation design, and navigation realization. first, in navigation analysis domain is analyzed by using use case, focusing on navigation. Next, in navigation design three models have been produced: a navigation information model, a profile, and a navigation interface model. Finally, in navigation realization a Webpage navigation model and a component navigation model have been produced. In this work, several formal definitions and rules for checking validity of navigation model have also been provided.

선행적이며 지속적인 테스트를 강조하는 테스트 주도개발이 시스템의 품질과 개발 생산성을 제고한다는 연구가 보고되고 있다 [4]. 그러나 대부분의 연구는 실험실 환경 또는 소규모 프로젝트를 대상으로 수행하였고, 개발 현장에서의 효과를 검증한 결과는 드물다 [2, 5, 18]. 본 연구는 비즈니스 환경의 대규모 프로젝트에 테스트 주도의 개발방법을 적용한 경험과 교훈을 보고한다. 다양한 데이터, 업무간 복잡한 연계, 철저한 검증의 필요성과 같은 전사적 응용체계의 요구사항은 기존의 테스트 주도 개발방법을 그대로 적용하기 어렵게 한다. 따라서 본 연구에서는 테스트 주도 개발방법의 전사적 적용을 위한 프레임워크를 제안하고, 이를 기반으로 한 테스트 지원도구를 개발하였다. 도구는 GUI 기반의 테스트 관리 화면을 제공하고 관계형 데이터베이스에 테스트 데이터를 저장하여 테스트 케이스의 생성, 테스트 실행, 그리고 테스트 데이터의 관리를 지원하였다. 도구는 또한 스크립트 방식이 아닌 저장된 테스트 데이터를 이용한 회귀 테스트의 실행을 가능케 하였다. 지원도구를 이용한 전사적 테스트 주도 개발은 테스트 결과의 실시간 파악과 빈번한 변경관리를 용이하게 하는 것으로 평가되었다. 또한 전사적 테스트 주도 개발방법의 보편적인 적용을 위해서는 전통적 개발방식에 익숙한 개발자들의 새로운 접근방법에 대한 거부감 해소, 테스트 주도 개발을 고려한 개발체계와 프로젝트 관리, 그리고 개발자 행태와 프로젝트 특성을 감안한 지원도구에 대한 후속 연구의 필요성이 식별되었다.

Because of the internet development, most of people can acquire the information freely. But it have the disadvantages. A remarkable thing among the disadvantages is the internet attack. Internet attacks were given damages to several fields. Specially, the damage is terrible to the economic side. Specially, company is susceptive to economic damage side. But it didn't execute a research about model that estimates damage to the economic side due to internet attacks. This paper presents a model that estimates the damage to economic side due to internet attacks.

In this paper, we propose an architecture for geosemantic services. With the rapid progress of web services, wireless internet technologies and popularization of smart phone in recent years, a lot of applications based on geographic information are being developed. Moreover the search portals empowered by semantic web technologies are enabling general users to access on-line resources more easily. However, several studies in GIS domain have pointed out the practical limitation of existing service patterns, which are limited only to linking heterogenous spatial databases, insufficient for several important use cases. Hence we draw functional elements of geosemantic services from GIS and semantic web standards, and present the use cases and a new architecture for geosemantic services. This approach could set a foundation to implement geoemantic services.

Capture-and-replay technique is a common automatic method for GUI testing. Testing applications on Android platform cannot use directly capture-and-replay technique due to the testing framework which is already set up and technical supported by Google and lack of automatic linking GUI elements to actions handling widget events. Without capture-and-replay testing tools testers must design and implement testing scenarios according to the specification, and make linking every GUI elements to event handling parts all by hand. This paper proposes a more improved and optimized approach than common capture-and-replay technique for automatic testing Android GUI widgets. XML is applied to extract GUI elements from applications based on tracing the actions to handle widget events. After tracing click events using monitoring in capture phase test cases will be created by communicating status of activated widget in replay phase with API events.

This study aims to figure out the development of Korean child welfare between 1950s and 1970s in the light of Children's Light as the oldest professional journal of social welfare in Korea. This journal had been published by CCF Superintendent Korea Conference from 1957. Particularly, this study has been conducted through the social historical perspective, and the collected data was analysed by three periods, institution-centered care era(1957-1961), home-centered care era(1962-1969), and expanded services era(1970-1979). Finally, the resultant themes are as follows: firstly, orphans' forster under social prejudice, social work inclined to Christianity, and institution-centered social casework based on faith; secondly, development of systematization on the whole social welfare, rising of social work professionalism, tasks for orphans and workers in orphanages, and expectations on the integration of practice; and thirdly, strengthening of children's education and health in the institution, questioning on deinstitutionalization, preparation against withdrawal of foreign aid agencies, and the government's passive correspondence. Unfortunately, this study limits to reveal the children's services by non-Christian agencies because of the data based on the services by Christian agencies.
