여러 장치들과 연동하여서 동작하는 네트워크 시스템 개발 시, 회귀 테스트는 전체 시스템의 안정성을 보장하기 위한 가장 필요한 테스트중의 하나이다. 그러나, 서비스가 되고 있거나 연동을 위한 추가적인 장비가 필요할 경우 테스트의 제약을 받게 된다. 본 논문에서는 자동 회귀 테스트를 위한 가상 네트워크 망을 제공하는 시뮬레이터를 디자인 한다. 또한, 시뮬레이터를 효율적으로 관리 및 동작하기 위한 UI 환경을 제안한다. 오픈 소스를 기반으로 제작된 본 시나리오의 관리 툴은 회귀 테스트의 자동화와 시나리오의 생성 및 배포가 가능하며 여러 프로토콜을 통합하여 사용할 수 있는 환경과 검증 코드를 제공한다. 이로 인해 네트워크 시스템 상의 소프트웨어에 대해 기능 및 회귀 테스트가 가능해 질것이고 결과적으로 프로그램의 개발 시간 단축과 유지보수에 탁월한 환경을 제공받게 될 것이다.

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.

Embedded system is tightly coupled with heterogeneous layers such as application, as kernel, device driver, HAL and hardware. Embedded system is customized for the specific purpose and hardware. In addition, the product cycle is so fast that software and hardware, which are developed by several vendors, are integrated together under unstable status. Therefore, there are lots of possibilities of faults in all layers. Because embedded software developers test their codes integrated with faulty layers, they cannot confirm 'whether testing of every aspects was completed, their code was failed, or integrated software/hardware has some problems'. In this paper, we propose an embedded software interface test method and a test tool called Justitia for detecting faults and tracing causes in the interface among heterogeneous layers. The proposed technique is an automated method which improves debugging upto professional testing using an emulator for helping developer.

Pavement crack sealing method, which is one of the methods to maintain and repair the road, prevents the extending of cracks by repairing cracks in its early occurrence and has already been applied to many roadworks in advanced foreign country for a long time. But in the conventional crack sealing method, traffic accidents occur frequently during the repair because it's commonly performed on the heavy traffic road or highway. It also has some difficulties in securing the safety of workers from the risk of burns caused by heated sealant. In an effort to solve these problems, automated pavement crack sealing machines such as ARMM, OCCSM, TTLS have been developed in advanced foreign country since early 1990s. Also APCS in 2004 and ACSTM in 2013 were already developed domestically. However, since these automated crack sealers developed from a number of research institutions have different test-bed conditions and productivity measurement models, it's difficult to compare and evaluate them objectively. In this study, the image processing time of the respective machines and the movement time of each motion on the work process were estimated by using fully autonomous mapping and semi-automatic mapping in order to measure the productivity in the same environmental conditions. In addition, the productivity measurement test-bed reflected domestic road characteristics was designed to estimate and compare the productivity of the automated crack sealing machines.
