Abstract

The invention relates to a software reliability testing method and device based on code tracking, belongs to the technical field of software testing, and solves the problems that in the prior art, code tracking is lacked, and static information extraction is not suitable for detecting the consistency of a model and a code. The method comprises the steps of tracking from a reliability strategy model to the code to obtain a reliability strategy code, wherein tracking comprises positioning and mapping; acquiring a Log file based on reliability strategy code instrumentation, wherein the Log filecomprises execution path information of the reliability strategy code; constructing a code LTS based on the Log file; constructing a reliability strategy UML time sequence diagram model; converting the reliability strategy UML time sequence diagram model into a model LTS; extracting branch paths of the code LTS as code paths, and extracting all branch paths of the model LTS as model paths; and judging whether the model path is matched with the code path. Code tracking and an accurate model and code dynamic consistency checking method are realized.

Description

technical field [0001] The invention relates to the technical field of software testing, in particular to a code tracking-based software reliability testing method and device. Background technique [0002] Software reliability refers to "the ability of software to perform the required functions under limited conditions within a given period of time". In the requirements description phase of a software system, system requirements are usually described as functional requirements and non-functional requirements. As an important part of non-functional requirements, reliability requirements describe the reliability constraints of the system. Reliability design is to formulate decisions and provide solutions for reliability requirements, and it is a mechanism to ensure that the system can operate normally when it encounters a failure. [0003] In the design stage, modeling based on reliability design provides guidance and basis for code developers to realize the expected design....
