Problems solved by technology

The method based on the Musa software operation profile is essentially a description of the unconditional probability distribution of the input space elements, without involving the interdependence between input variables, and thus cannot reflect the influence of time factors on software use, and cannot accurately describe the software use process
However, the profile construction method based on the Markov process reflects the dependence of software input to a certain extent, but the assumed non-consequence of software use cannot accurately reflect the historical use process of software.
Since the current software, especially embedded software, is complex to use and has many constraints between inputs, a more effective method is needed, which can not only describe the complex software usage, but also facilitate the generation of software reliability test data. Methods

Abstract

The invention discloses a method for generating the reliability test data of real time embedded software, belonging to the field of software reliability. The method comprises the following steps of analyzing interfaces and relative environments of tested real-time embedded software and hardware of the tested real-time embedded software, sorting out input and output variables, and establishing a system analysis chart; establishing use types of the input and output variables; establishing use profiles and operation description graphs according to the use condition of a tested system; organizing data and randomly sampling according to the information of the established use profiles and operation description graphs, and then generating software reliability test data. The method of the invention clearly describes the use process and the use input distribution of the software, can more efficiently and automatically generate the software reliability test data, and improves the efficiency of the software reliability test.

Description

technical field [0001] The invention relates to the field of software reliability, in particular to a method for generating test data for real-time embedded software reliability testing. Background technique [0002] The process of software analysis, design and implementation is the process of introducing software defects, while software testing is the process of eliminating defects in software. It has become a consensus that software testing can discover potential software defects and improve software quality. However, conventional software testing, such as unit testing, integration testing, system testing, etc., is aimed at discovering software defects, but it can't do anything for the quantitative measurement of software reliability. Because software reliability is closely related to software usage, it is necessary to reflect the user's usage of the software in the test, which is a statistical testing method based on user usage. Software reliability testing can use the ...
