Research Of Software Quality Assurance Based On Test Design Standardization

With the extensive application of computer software, software quality has become the focus of attention, so software quality assurance has become a crucial task in software engineering field. The late 60 of the 20th century, C.A.Hoare and E.W.Dijkstra as a representative of a group of computer scientists, put forward a formal function of the statute to software quality problem, describe the user requirements and lay out a new method of software development that can greatly improve software quality, reduce or even abolition of software testing. However, software testing and evaluation have been the rapid development, in fact software testing and evaluation have become an essential part of software quality assurance in software production. Proven by software engineering, software testing is a complex, time-consuming and troublesome activities, so we must pay attention to scientific test strategy and methods in the test design process to reduce costs and to improve test efficiency.At present test design process still has a lot of problem, for example test case design is not standard, test strategy is difficult to ensure software quality. At home and abroad, the research of software quality assurance techniques have made a series of results, and is widely used in software engineering practices, such as Boehm, McCall, ISO/IEC 9126 and other quality metrics model. However, test design has few studies, therefore, research of test design process standardization, for example test case design standardization, in order to save resources and improve the efficiency of software testing is of great significance.In this paper on the learning of software quality assurance and software testing technical theory, on the basis of the existing research results, mainly to discuss and study at the following aspects:First, this paper gave a definition of test design, then according to this definition,described the work task of test design.Second, standardization is introduced into test design to ensure software quality. In order to achieve a limited time and resources to a more reasonable budget for testing, this paper discussed test case design standardization which is an important part of software testing process, so that get the most effective software quality assurance.Third, in order to make the software testing can find more bugs in test design, this paper gave an effective test strategy to improve software error detection rate,so to effectively save testing resources, improve test efficiency and achieve better software quality assurance purposes.Finally, through specific case in practice, we compared the test result of the improved model applied to the project with traditional test design, and concluded that test design standardization methods have more advantages in software quality assurance.
