현재 안드로이드 시장에는 다양한 플랫폼을 기반으로 한 디바이스들이 혼재하고 있고, 안드로이드의 성장세로 봤을 때 앞으로 더욱더 많은 플랫폼 및 디바이스가 출시될 것이다. 따라서 여러 플랫폼 및 디바이스에 대한 상호 호환성을 만족시키기 위해 안드로이드 소프트웨어 개발 단계부터 테스트의 중요도가 높아지고 있고, 테스팅 시간을 줄이기 위한 테스트 자동화 문제가 대두되고 있다. 이러한 환경에서 상호 호환성을 만족시키기 위해서는 소프트웨어적인 요소뿐만 아니라 프로그램의 전반적인 요소까지 고려해야 하지만 기존의 테스트 자동화 도구인 JUnit은 안드로이드 소프트웨어의 특정 상태에 대한 정보만을 도출하기 때문에 전반적인 요소에 대한 통합관리가 불가능하다. 따라서 본 논문에서는 안드로이드 소프트웨어의 전반적인 요소들에 대한 정보를 도출하여 테스트 케이스를 자동으로 생성하는 방안을 제안한다. 사용자가 도출하고자 하는 정보를 선택함으로써 테스트 케이스 생성에 대한 유연성이 증가하고, 이를 자동화함으로써 테스팅 시간 감소를 통해 생산성 향상 및 높은 품질의 안드로이드 소프트웨어를 기대할 수 있다.

In order to test reflecting the features of a development methodology and domain, it is required to tailor process standards and perform testing according to the tailored process. However, since commercial testing tools support only a part of the tailored process, it is essential to either acquire or develop testing tools appropriate for a development environment. This paper proposes a method to develop a test process execution tool which has common features of standards, and variousness in methodologies and domains. ‘Test Process Execution Tool: Test PET’ which is a test process execution tool developed adapting the concept of product line. Our Test PET generates the test process suitable for the development methodology and domain and then executes the produced test process.

With the rapid growth of WWW, the existing systems are integrated into web and various web-based systems are developed. Unlike the general applications, web aplications are developed by combining the various technologies and have their own complexities. So, we have much difficulties in the development and maintenance of web applications. To accommodate to the rapidly changing business environments and user requirements, the continuos evolution is required. In this paper, we present a method for supporting the effective development and maintenance of web applications. Our method involves the extraction of web application's structure information and analyzes web log ales containing the useful information about web site. We also describe a web testing method using the attracted information and our system developed for extracting hyperlink information and analyzing web log.

It is highly requested that the more complicated embedded software is used for high performance and multiple functions of the systems. This is inevitably increasing the errors. Therefore the embedded software testing is getting important recently. There are not general testing methods which are able to be applied for any embedded systems, but via this research, we introduce a testing method which is based on TTCN-3, a testing standard, for embedded systems. A testing environment for network-based embedded software is implemented with considering the features of TTCN-3 testing which is based on message exchange. The testing environment has two additional parts with TTCN-3 test system, the network analyzer to access the network-based systems and the communication interface which is suggested for embedded systems in previous work, and we have implemented the whole testing environment with interacting these two parts. In addition to the normal testing domain, called single node testing as a unit testing of V-model, we suggest another concept to test multiple nodes in network. It could be achieved by adding keywords such as supervisor and object which are describing the feature of TTCN-3 testing component and generating the TTCN-3 Executable code which contains new keywords. The testing has done for embedded software which is based on CAN network and the demonstration of the testing environment has been shown in this paper.

Recently relationships between reliability measures and the coverage have been developed for evaluation of software reliability. Particularly the mean value function of the coverage-based software reliability growth model is important because of its key role in rep-resenting the software reliability growth. In this paper, we first review the problems of the existing mean value functions with respect to the assumptions on which they are based. Then a new mean value function is proposed. The new mean value function is developed for a general testing environment in which imperfect fault detection and repeated construct execution are allowed. Finally performance of the proposed model is empirically evaluated by applying it to a real data set.

The context-awareness of mobile applications yields several issues for testing, since mobile applications should be able to be tested in any environment and under any contextual input. In previous studies of testing for Android applications as an event-driven system, many researchers have focused on using generated test cases considering only Graphical User Interface (GUI) events. However, it is difficult to find failures that could be detected when considering the changes in the context in which applications run. It is even more important to consider various contexts since the mobile applications adapt and use the new features and sensors of mobile devices. In this paper, we provide a method of systematically generating various executing contexts from permissions. By referring to the lists of permissions, the resources used by the applications for running Android applications can be easily inferred. To evaluate the efficiency of our testing method, we applied the method on two open source projects and showed that it contributes to improve the statement code coverage.

Component technologies which enable quickly and effectively to develop software have begun to come into the spotlight since early 1990s. Currently, a number of software development works are performed on the J2EE/EJB environment. However component testing is a very complicated task, in addition it requires more efforts than the previous Java class testing. Thus many developers do not perform sufficiently testing works. In this paper we propose an automatic testing method for EJB components based on the in-container testing strategy and implement a testing tool. Since our method builds automatically the test environment for EJB components, it is possible for developers or testers to save their time and efforts at the test preparation phase. Therefore we are convinced that the reliability of EJB components can be increased through sufficient testings with our method.

X-Forms 기반의 웹 UI(User Interface)를 개발하는 소프트웨어는 개발이 완료되어 운영되는 과정에도 사용자의요구, 성능향상, 기능개선, 기능추가 등의 이유로 변경이 가능하다. 이러한 소프트웨어의 유지보수도 일반적인 요구사항명세, 분석, 설계, 구현의 개발 프로세스를 따른다. 본 논문에서는 UI 개발 소프트웨어의 유지보수 단계에서 효율적인 테스트를 하기 위해 V-모델을 확장, 변형한 테스트 프로세스 제안한다. 제안한 테스트 프로세스의 주요 활동은 요구사항분석을 통한 테스트 계획, 테스트 데이터를 식별하고 환경을 구축하는 분석과 설계, 테스트 케이스를 명세화하고 테스팅 방법론을 적용하는 구현과 실현, 리포팅과 산출물을 정리하는 테스트 마감 활동으로 진행한다. 웹 UI 개발 소프트웨어의 특징에 맡게 테스트 프로세스를 구축하고 실무에 적용하여 에러 검출률, 테스트 시간, 테스트 결과의 효율성을 높일 수 있는 방법을 제안한다.

According to increasing requirments in embedded systems, embedded software has been more complicated then before, a software developer is required to test her/his software to make a efficient embedded system software in both time and space. This paper suggests a testing tool with which a software developer can easily test the embedded system software in cross-development environments. The suggested tool is designed based on host/target architecture, to provide an intuitive test environment in which a test case can be executed in a target board. The tool uses an XML-based test script to generate an appropriate test case. It includes a tree-based test script editor with which a developer can easily make a test case. Therefore, with the suggested tool, a develop can put down a burden on an software testing and get more productivity in software development related on embedded system.
