자동화 테스트 도구를 활용한 산업용 자동화 소프트웨어의 효율적인 회귀 테스트

In these days technologies of industrial automation have been drastically developed. The cycle of product development has been decreased and the complexity of product has been increased. Therefore the importance of an efficient regression testing came to grow for reliability of product. In this paper we propose the proxy module to connect testing automation tool with industrial automation software. This proxy module can analyze scripts from a testing automation tool and then provide proper functionality for application using APIs shared with software. We evaluated performance based on Return On Investment (ROI) with QuickTest Professional and XG5000. The performance result shows an initial expense for constructing testing automation system is costly. But total expense became cheaper than manual testing as regression testing accomplished repaetedly.
