Bug test evaluation method for quality of each stage of software life cycle

Abstract

The invention discloses a Bug test evaluation method for the quality of each stage of a software life cycle, which can realize the automation of evaluation and improve the software quality evaluation efficiency and reliability. The method is realized through the following technical scheme: according to different stages of a software life cycle, taking six aspects of a program error Bug introduction stage, a Bug discovery stage, a Bug defect grade, a Bug number, a Bug generation reason and a Bug correction coefficient as metric elements, and respectively establishing software quality mathematical evaluation models of demand analysis, design, coding and test stages; using an improved weighted fuzzy number entropy weight method, and calculating the Bug generation reason metric element weight coefficient of each stage; introducing a Bug correction coefficient according to the software correction error cost, and obtaining a subtraction item of the third dimension in the test stage; and establishing a software quality evaluation system model according to an overall quality reduction evaluation formula S = R + D + C + T, and iteratively obtaining software overall quality evaluation S.

Description

technical field [0001] The invention relates to a quality evaluation method at different stages of a software life cycle (SoftwareLifeCycle, SLC), mainly including quality evaluation methods at a requirement stage, a design stage, a coding stage, a testing stage and an overall software quality evaluation method. Background technique [0002] With the advancement of science and technology and the development of computer technology, the application range of computers is becoming more and more extensive, and software products occupy an increasingly important position in daily production, life and work. As a result, computer software has become more and more complex. The life of a product is the quality of the product. Computer software products are like other products. Quality problems also exist in the entire life cycle of software products, and now the problem of software quality is increasingly prominent, so software quality evaluation has become a subject of increasing conc...

Problems solved by technology

[0005] The current software quality-related standards are the basis for most companies to evaluate software quality, but the existing standards are not aimed at a specific stage, but are conceptually general and abstract general models. Software quality evaluation and implementation in specific stages are not yet mature in our country, and Most of the evaluation technologies come from foreign software quality-related standards, with almost no independent property rights, and a unique evaluation system

In addition, in China, software quality evaluation is still in its infancy, domestic research work is mainly concentrated on the qualitative research of software characteristics and sub-characteristics, and there are relatively few studies on software metrics

For the stages most closely related to software quality issues in the software life cycle, including requirements analysis, software design, software coding and software testing, on the one hand, there is a lack of extraction of qualitative and quantitative indicators; on the other hand, there is no scientific Rigorous Stage Quality Evaluation Model
