EP600DC-3 Article About

Traditional software testing is in the "software is the code" to expand on the form. Changes in the way of software for many years, more and more service-based software architecture began to appear, and with the rise of SOA, this trend becomes more apparent. The new service is based on packaged software will be assembled from components, so the quality of components becomes very important. Any defective component could cause the hidden commercial systems. In recent years, how to more effectively test the components to ensure the quality of software engineering will become an urgent problem areas, the most challenging problems. To this end, Beihang software component testing technology and its focus on support tools have been carried out years of research work. They proposed a "common software testing technology" and its support tools QETest have been a number of software companies and large-scale software testing project has been successfully applied. On this basis, the cooperation of the component technology to establish joint laboratory will focus on the promotion component testing technology and its support tools in the development and practical use.
