최근 GUI 컴포넌트는 소프트웨어의 중요한 성공 요소이다. 따라서 GUI 컴포넌트는 반드시 검증되어야 한다. 그러나 소프트웨어의 GUI 검증을 위한 테스트에는 많은 시간과 비용이 소요된다. 이러한 자원의 소비를 줄이기 위해서는 GUI 테스트의 자동화가 필연적이다. 본 논문에서는 GUI 테스트를 수행하기 위해 고려해야 할 문제를 논하고 기존치 Record & Play-back 기술을 기반으로 한 GUI 테스트 케이스 생성 기법을 보완한다. 이를 위해 스파이 기술을 이용한 이벤트 생성 방법과 이렇게 생성된 이벤트를 그룹화하여 다양하고 효과적인 시나리오 생성 방법을 제안한다. 그리고 이렇게 생성된 시나리오를 바탕으로 GUI 테스트 케이스 생성 방법을 기술한다.

The aim of this paper is development of resistivity seismic dilatometer (RSDMT) system. The resistivity module for obtaining apparent resistivity depth plot and seismic module for obtaining shear wave velocity (Vs) depth plot are attached to the conventional flat dilatometer testing equipment. From shear wave velocity profile, the stiffness at low strains of a site can be evaluated in undisturbed condition. And the resistivity value contains some information about water content and mineral characteristics of clayey soil. Specially manufactured resistivity and seismic modules were connected between commercialized DMT blade and drilling rod. To enhance reliability and repeatability of RSDMT test, automatic testing system including notebook based data acquisition system and automatic surface source system were developed. RSDMT system can be performed rapidly and can obtaine more reliable data at the same point compared with the separated testing system. The verification studies for the developed RSDMT system are going to be performed. From these studies, the effectiveness of integrated hybrid testing system will be checked in light of proper evaluation of geotechnical design parameters of clayey soils.

소프트웨어가 대형화 및 복잡화되고 품질보증 및 관리에 대한 요구가 한층 커짐에 따라 소프트웨어 테스트 활동이 중요시되고 있다. 소프트웨어 테스트 활동은 시스템에 존재하는 결함 발견과 처리가 주요 목적이지만, 현재 시스템의 위험요소를 관리하기 위한 요구 또한 존재한다. 하지만 일반적인 테스트 자동화 도구에서는 테스트케이스를 이용하여 동일한 순서로 테스트를 수행하며, 이러한 테스트 방식은 빈번하게 변경되는 소프트웨어를 테스트함에 있어 결함을 조기에 발견할 가능성이 낮아지고 처리되는 시간이 늦어지게 된다. 이에 따라 본 논문에서는 과거 테스트 이력을 이용하여 테스트케이스에 동적인 가중치를 부여함으로써 위험도가 높은 테스트케이스를 우선적으로 테스트 하여 결함을 빠르게 발견할 수 있도록 가중치를 이용한 테스트케이스 동적 관리 기법을 설계하였다.

Parallel processing has the potential to be cost effectively used on computationally intense power system problems. But this technology is not still available is not only parallel computer but also parallel processing scheme. Testing these algorithms to ensure accuracy, and evaluation of their performance is also an issue. Although a significant amount of parallel algorithms of power system problem have been developed in last decade, actual testing on processor architectures lies in the beginning stages. This paper presents the parallel processing algorithm to supply the base being able to treat power flow by newton's method by the distributed memory type parallel computer. This method is to assign and to compute teared blocks of sparse matrix at each parallel processors. The testing to insure accuracy of developed method have been done on serial computer by trying to simulate a parallel environment.

Stockigt sizing test, which is readily affected by individual tester's bias as well as testing conditions in recognizing red coloration, had to be modified to improve its reliability and reproducibility. The novel testing system with the automatic recognizing program of red coloration was developed with the auxiliary equipments including an automatic liquid dispenser and a specimen shifter. The analysis program used a hue value of a droplet image in recognizing a point of time on red coloration instead of RGB values that are not similar to human perception of color. Hue was more sensitive in recognizing the red coloration of a droplet than the other two factors, Saturation and Value. During the test, the program records the time consumed up to a specific hue value of a droplet on a specimen. Differently from the conventional test, the automatic test could obtain a reliable and reproducible sizing degree with a minor error. Furthermore, the Stockigt sizing degree measured by the automatic system showed great correlations with contact angle and Hercules sizing degree. It means that such great correlations will contribute to the development of an integrated measuring system capable of predicting contact angle, surface tension, surface energy and Hercules sizing degree of paper and paperboards through the Stbckigt sizing test. It was meaningful to note that the automatic system for Stbckigt sizing test might be able to used to predict contact angle, Hercules and Cobb sizing degree, based upon the high correlation coefficients.

Computer testing system for pumps is an automatic measuring and testing system micro computer. There are two functions to this system. 1. Automatically controlling the testing processes. It includes controlling to testing devices, adjusting test points and starting or stopping the pump. 2. Automatically collecting and calculating the testing data. It includes the collection and calculation of the parameters to be measured, printing the testing reports and plotting the testing curves. When using it the measuring accuracy may be improved and the time for testing may be compressed by use the system . So it is used widely on the world. In this paper the basic construction and the work principle and the testing processes are described.

This paper introduces the development of automatic system for estimation of digital relay performance. We have developed an automatic estimation system "HRV2004(Himap Relay function Verifier 2004)" for digital relay in 2004 and it has been verified in the field for one years. This paper describes the development details and field experience of HRV2004. HRV2004 can perform a series of jobs required for the relay testing in one environment and could handle most of all models of protective relay currently produced by Hyundai Heavy Industries. The functionality of this program consists of GUI of relay setting for beginner, fault record analysis and relay performance estimation. The core of this system is an automatic reporting of estimation test. If user is only click a button for relay estimation and one will received testing report to deliver customer. Additional benefit is fast response than the manual estimation. For example, the manual estimation takes spending 6 hours but this system is about 15 minutes.
