Environmental Protection Class Software Quality Evaluation Model And Practice

Software quality is the life of software products, software, software quality assurance testing as a means of more and more people's attention, rigorous testing is to ensure that an important part of software product quality. Software testing to follow a certain standard (technical), if not at the standard test, the quality must be poor, so in strict accordance with norms and standards for testing is the key to quality assurance testing. China third-party evaluation institutions with special reference to the test standard is more than one GB/T16260 "Software Engineering Product Quality" series of standards (ISO / IEC 9126:2001, IDT). Application of the GB/T16260 in the initial stage of data and experience is almost zero. So, the implementation details of GB/T16260 is necessary.Software testing is put into operation in the software before the software requirements analysis, design specifications and coding of the final review, is a key step in software quality assurance. Software testing is to find errors and execution process [1], so the purpose of software testing is as much as possible to find and correct software errors, improve software quality. EW Dijkstra once said: "Program testing can only show the existence of the error, but can not show that the errors do not exist." Visible, testing is to make software defects implied in less than a certain value, the output, input than the maximum.This paper is to address the problem of China's software testing organization as a member of the Union claim the protection class I units of software quality evaluation model and practical issues, type of software evaluation model for environmental protection were innovative and exploratory research. By GB/T16260.1 and GB/T16260.2 analysis and applied research, the formation of some of the accepted areas of software quality models and metrics element to improve the level of understanding and application of standards to improve the operability of the software evaluation and comparable sex.Firstly, through the analysis of environmental protection type software, type of software commonly summarized environmental functions, features, quality requirements and application profiles, and the characteristics for environmental protection and conventional type of software quality requirements, that software should be the focus of the test . On this basis, describes the evaluation of product quality related to quality characteristics involved, the choice of sub-feature basis and method, and gives a more general class of software quality models for environmental protection. The main contents are:1. The quality of software definitions and measurement yuan determine;2. Combined with a practical environmental protection software products, given the quality of environmental protection type of software application of the model example, in the example illustrates the evaluation process, evaluation results, and the practice of common problems and solutions.3. How to apply the quality evaluation model for the application of its quality in environmental protection software products.
