Abstract

The invention relates to a method for estimating intervals of software reliability indexes based on test features, comprising: analyzing the test features from multiple angles, designing corresponding criteria to measure the test features, and obtaining test feature measurement results; according to the test feature measurement results and According to the relationship between the reliability index and the regression model of the reliability index and the test feature measurement, the interval estimation of the reliability index is carried out according to the regression model of the reliability index and the test feature measurement. The present invention finds the relationship between the reliability index and the test feature by constructing a regression model of the reliability index and the test feature, which has a theoretical mathematical basis and is more scientific and rigorous; it uses the test feature data generated during the actual test to assist in the reliable The interval estimation of the reliability index improves the credibility of the interval estimation of the reliability index.

Description

technical field [0001] The invention relates to the technical field of software reliability evaluation, in particular to a software reliability index interval estimation method based on test features. Background technique [0002] Software is ubiquitous in our lives, and plays a very important role in various industries and fields. In safety-critical systems, software failures can have severe, fatal consequences. The unpredictability of software defects makes it impossible to know when and how software will fail. Although the reliability of hardware systems has developed in recent years, the reliability of software systems still cannot meet our expectations. It is precisely because of the importance of software reliability and the fact that there are many unsolved problems in this field that software reliability has received more and more attention. [0003] As a software measurement index, software reliability summarizes the reliable operation degree of software through ...
