Embodiment Construction

[0034] The present invention will be further described below with reference to the accompanying drawings in conjunction with the embodiments, so that those skilled in the art can better understand the present invention and implement it, but the given embodiments are not intended to limit the present invention.

[0035] Content of the present invention mainly is following 3 parts:

[0036] 1. Construction method of judgment matrix

[0037] The credible nature of software quality is composed of many elements, such as MTTF, integrity, stability, etc. for reliability; MTTUF, integrity, and confidentiality for security; MTTUF, integrity, and confidentiality for maintainability. The elements are easy to analyze, easy to change, stability and so on. Of course, these elements do not necessarily reflect a certain credible nature, and there may be overlaps between them. For example, integrity is an element reflecting both reliability and security; stability is an element reflecting mai...

Abstract

The invention discloses a method for calculating a minimal software believability test case number. The method comprises the following steps of: constructing a hierarchical structure model by an analytic hierarchy process (AHP), and establishing a judgment matrix according to the hierarchical structure model; determining the value of the judgment matrix by a professional Delphi method; and determining the minimal test case number in an engineering practice by a classical statistical hypothesis theory. The hierarchy of software believability comprises a destination layer, a criterion layer and an object layer, factors in each layer are compared in couples, a coupled comparison matrix is established, and the judgment matrix is constructed on the basis of the coupled comparison matrix. The method has the advantages that the minimal test case number of the believability is calculated by the AHP and the classical statistical hypothesis theory according to elements which are provided by ISO/IEC9126 and influence the software believability, and on the premise of ensuring the complete test of believable software, test cases are reduced as many as possible, and test cost is saved.

Description

【Technical field】 [0001] The invention relates to software testing, in particular to a calculation method for the minimum number of test cases of software credibility. 【Background technique】 [0002] Software has penetrated into various fields of national economy and national defense construction, and plays a vital role in the information society, and people are increasingly dependent on software. However, the quality of the software is unsatisfactory, and the software often fails, which has adverse effects on people's work and life, and even causes huge losses. For example, the failure of the Ariana 5 rocket launch and the accident of the Therac225 radiation therapy device are blood lessons. These influences and facts make people pay great attention to the trustworthy properties of software such as correctness, reliability and security. In the United States, DARPA, NSF, NASA, NSA, NIST, FAA, FDA and other DoD agencies are actively involved in the research and development ...
