With greater utilization of web application and growth of its market, the function of such application is being expanded With today's increasing demand for high quality software, we see a sharp rise in the interest for web application test. The current trend is that web applications are being developed based on a framework of developmental environment. Hence, as the scope of that framework expands, each module of the entire web application is being configured by the combination of heterogeneous files. The distinctive characteristics of a web application are based on the fact that the framework that is provided in partially completed form controls the structure of all objects of development. The present study defines the web business logic as a minimal unit which has meaning as a unit of application for the web application. In this paper, we define web business logic as a least meaningful execution unit of web applications, propose how to generate automatically the BizUnit test code for it, and analyze the effectiveness of testing of the web application via the BizUnit test codes.

복잡하고 난해한 웹 응용을 이해하고 테스트하는 것은 사용자가 요구하는 품질을 만족시키기 위한 필수적인 과정이지만 실제로 이 과정을 제대로 수행하는 것은 쉬운 일이 아니다. 지금까지 웹 응용의 테스트를 위해 여러 가지 프레임워크가 제시되어 사용되고 있지만 이러한 프레임워크의 효율성은 어떤 접근법을 사용하느냐에 의존적인 경우가 많다. 본 논문에서는 웹 응용 상태를 표현하는 도메인 모델과 테스트 활동 그래프를 통해 객체의 활동과 의존성을 표현하여 웹 응용의 정확성을 검증하는 테스트 기법을 제안하고자 한다. 이 기법은 웹 응용을 사용자가 이해하기 쉬운 활동으로 모델링하여 테스트할 수 있도록 도와줄 수 있으므로 업무의 효율성과 편의성을 증대시킬 수 있을 것으로 기대된다.

The web environment is evolving rapidly. Testing in the web based software is an essential process to improve stability and productivity. Testing of complex web contents and ill(user interface) is most important thing. Implemented test cases are efficient when they are automated and reusable. But, most of the testing automation tools are focused on technical accessibility and functions still. A collaboration of the persons concerned and reusability of implemented test case are ignored. In this paper we propose an efficient way to design automated test case in web environment, and to share and pattern automated test cases we introduce testing framework called NTAF(NHN Test Automation Framework.). The NTAF is based on open source framework. It provides integrated testing environment that web testing cane be automated and managed continuously.

최근 많은 웹 어플리케이션은 오픈소스 프레임워크를 이용하여 개발되면서 개발환경과 개발방법이 표준화 되어 개발 생산성이 향상되었다. 그러나 여전히 운영 및 유지보수 측면에서의 비용은 줄어들고 있지 않다. 하지만 테스트를 자동화 하면 시스템을 수정할 때 좀더 안전하게 수정하고 또한 수정하는 부분이 시스템 전체에 미치는 영향을 최소화 할 수 있다. 이에 본 논문에서는 오픈소스 프레임워크인 Struts2를 이용하여 웹 어플리케이션의 테스트 자동화 방법을 제안한다.

Due to the increase of the attention on relation extraction systems, the construction of test collections for assessing their performance has emerged as an important task. In this paper, we propose semi-automatic framework capable of constructing test collections for relation extraction on a large scale. Based on this framework, we develop a test collection which can assess the performance of various approaches to extracting relations between technical terminologies in scientific literatures. This framework can minimize the cost of constructing this kind of collections and reduce the intrinsic fluctuations which may come from the diversity in characteristics of collection developers. Furthermore, we can construct balanced and objective collections by means of controlling the selection process of seed documents and terminologies using the proposed framework.

In this paper we design and implement a management framework base on JMX to control and manage ubiquitous home networks. To do this, we organize the ubiquitous home network test-bed that consists of information electronics and sensor devices. In the test-bed network, we implement the management framework which can control and manage various applications and devices in home network environment. In addition, it can also define and add new services easily. Moreover, it is possible to provide various management interfaces with multi-protocols. The framework is formed to integrate legacy management systems readily.

Capacity of modem storage devices is becoming larger than yesterday and integration of disk is increasing. It refers that physical errors can damage a lot of digital information on storage devices. So we propose file system test framework in this paper to test integrity and robustness of file systems. We develop the tool for generating bad sectors on disks and the tool which creates all physical errors defined in storage devices. We also develop the tool for immediately monitoring the condition of read and write execution on storage devices. So, by integrating those tools, we develop FORT, test framework for confirming robustness of file system. We analyze robustness of ext3 file systems by FORT. Lastly, we present draft of intelligent system merging file system and device driver's layer architecture.

Simulation is the work that identifies the characteristics of some problem through the simulated experiments. During the experiments it is frequently required to change or replace the simulation models, algorithms, or input/output data. Especially, in the case of the simulation works performed by replacing algorithms, if a replaceable component that implements a specific algorithm is not correct with respect to its functionality it is very difficult to carry out the simulation works successfully. In this paper, we suggest a test framework that verifies functional correctness of the replaceable component in the software-based GNSS (Global Navigation Satellite System) simulation environments. When a component is replaced, this framework enables us to properly execute the functional test for the component according to its context.

Most of sensor networks are difficult to be debugged, verified, and upgraded once they are deployed in the fields, for they are usually deployed in real world and large scale. Therefore, before deploying the sensor networks, we should test and verify them sufficiently in realistic testbeds. However, since we need to control physical environments which interact with sensor networks, it takes much of time and cost to test and verify sensor networks at the level of resource-constrained sensor nodes in such environments. This paper proposes an efficient software framework for evaluating and verifying sensor networks in the view points of network and application operations (i.e., accuracy of sensing algorithms). Applying the proposed software framework to the development of a simulator for a smart parking application based on wireless sensor network, this paper verifies the feasibility of the proposed framework.
