Embodiment Construction

[0053] The complexity analysis method of the software defect detection system of the present invention will be further described in detail below in conjunction with the accompanying drawings and the embodiments of the present invention.

[0054] The complexity analysis method of the defect detection system (DTS) based on the module decomposition technology of the present invention includes:

[0055] Step 1, according to the defect detection principle of the software DTS, its analysis process can be abstracted into three logically independent modules (Module) (namely, the front-end input preprocessing module (Input Preprocessor), pre-analysis module (Pre-Analysis) and the formal analysis module (Formal Analysis)), that is, the front-end input preprocessing step is completed by the front-end input preprocessing module (Input Preprocessor), the pre-analysis step is completed by the pre-analysis module (Pre-Analysis), and the formal analysis module ( Formal Analysis) to complete t...

Abstract

The invention discloses a complexity analysis method of a software defect testing system (DTS) based on a modular decomposition technology, which comprises the following steps that: A. according to a DTS defect testing principle, the flow of the analysis method comprises a front-end input pre-processing step completed by a front-end input pre-processing module, a pre-analysis step completed by a pre-analysis module, and a formal analysis step completed by a formal analysis module; B. the complexity of all analysis units inside the front-end input pre-processing module, the pre-analysis module, and the formal analysis module is sequentially analyzed according to the calling sequence and the dependence relationship to obtain the property and the law of complexity distribution of each analysis unit; and C. according to the analysis results of a step B, the complexity distribution situation of the whole DTS System is obtained by statistic. By using the complexity analysis method, the complexity distribution situation of the whole DTS system is obtained by statistic through the complexity analysis of the analysis unit inside each module, and the defects that the traditional complexity analysis method is not systemic and comprehensive enough and the like are overcome.

Description

technical field [0001] The present invention relates to software testing technology, in particular to a method for analyzing the complexity of a software defect testing system (DTS, Defect Testing System) based on module decomposition technology, so as to discover the performance bottleneck of the defect testing system and improve the efficiency of defect testing and concurrent Perform multiple test tasks to provide a rationale. Background technique [0002] Static program analysis technology can obtain the semantic information of the program without dynamically executing the program by analyzing the source code. Complete program analysis technology can be applied to the process of defect finding, type checking, compilation optimization, etc. through the abstraction of program semantics (over-approximation). However, the negative impact of the abstraction of program semantics is that it increases the amount of calculation, resulting in a decrease in analysis efficiency. ...
