Abstract

The invention discloses a code defect detection method, which belongs to the technical field of software testing, and can improve the code defect detection accuracy. The method comprises the following steps of slicing a to-be-identified code according to a preset slicing criterion to obtain a to-be-detected slice code segment, inputting the to-be-detected slice code segment to a preset code defect detection model, and taking an output result of the preset code defect detection model as a code defect detection result, wherein the preset code defect detection model is a network model obtained by performing segmented learning on a statement semantic vector and a statement type vector in each slice code segment in a training stage.

Description

technical field [0001] The invention relates to the technical field of software testing, in particular to a code defect detection method. Background technique [0002] Code analysis and software testing are the main means of checking and discovering security flaws and exploits in software codes, and have always been research hotspots in the field of information security and software security. However, with the increasing complexity and scale of safety-critical and sensitive systems, as well as the frequent occurrence of software defects and the continuous increase of hacker attack methods, the difficulty of software defect detection is also increasing. Traditional code defect detection methods are difficult to balance high detection capability and detection efficiency, and cannot meet the needs of shortening software maintenance cycles and improving software quality and reliability. [0003] Existing code defect detection methods mainly include defect detection based on lex...
