Problems solved by technology

[0016] At the same time, the researchers found that the effectiveness of software testing technology is affected by the type of failure mode. At the same time, for block and strip modes, an efficient ART (adaptive random testing) method was proposed, but the ART algorithm for block and strip failures Great pattern effect, poor performance for dot pattern
At the same time, how to obtain the scope of the failure area is also a difficulty when the internal code of the program cannot be understood

Abstract

The invention discloses a method and a system for constructing a software failure area mode, which are used for positioning a program error and improving the technical performance of software testing,and comprise the following steps of: 1, obtaining a first failure point in software by adopting an efficient ART algorithm group according to an input domain of a software system, namely, inputting abnormal output of a program; 2, according to the first failure point, successively obtaining other failure region points under limited test resources; 3, obtaining more failure region information by using the existing failure point set to construct a failure region mode. and 4, determining the area of a failure area by adopting a multi-dimensional convex hull algorithm and aiming at the failure point set obtained in the step 2 or the step 3, determining the range of the failure area by adopting a linear programming method, determining the type of the failure area, and generating a failure areainformation file. The method saves the cost in software testing, and fills the blank in the field of obtaining the software failure area.

Description

technical field [0001] The invention belongs to the field of software testing, and relates to a method for constructing a software failure area mode, which clarifies the scope of the software failure area and realizes the location of the failure area. In the case of a clear failure area mode, the appropriate test technology is selected in a targeted manner, so as to improve the effectiveness of the test technology. Background technique [0002] With the vigorous development of software engineering technology, how to ensure the quality of software products has attracted more and more people's attention, and software testing has undoubtedly become an important part of ensuring software quality. Software testing is mainly divided into "white box testing" and "black box testing". Box testing", and for "black box testing", researchers have proposed many effective methods. However, the research found that the effectiveness of software testing technology is affected by the software...
