Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0022] The embodiment of the present invention provides a method for software fault context location, such as figure 1 shown, including:

[0023] Step 101. Obtain input parameters, and determine suspicious input parameters and suspicious value subfields and non-suspicious value subfields of the suspicious input parameters in the input parameters.

[0024]Specifically, since the present invention locates the fault context for software, it can be considered that the...

Abstract

The embodiment of the invention provides a method and a device for carrying out context positioning on a software fault, relates to the technical field of software testing, and is used for providing a context environment where the software fault is generated for a programmer and improving accuracy of positioning the software fault. The method comprises: acquiring input parameters, and determining doubtful input parameters in the input parameters and doubtful value subdomains and non-doubtful value subdomains of the doubtful input parameters; according to the doubtful value subdomains and the non-doubtful value subdomains of the doubtful input parameters, acquiring doubtful input parameter variation pairs; acquiring execution information of the doubtful input parameter variation pairs; according to the execution information of the doubtful input parameter variation pairs, establishing a program dependency graph of an execution failure test case and a program dependency graph of a corresponding execution success test case; according to the program dependency graph of the execution failure test case and the program dependency graph of the corresponding execution success test case determining fault content statements.

Description

technical field [0001] The invention relates to the technical field of software testing, in particular to a method and device for locating software fault context. Background technique [0002] With the rapid development of information technology, computer software has penetrated into all fields of society. In order to ensure the quality of software, implementing a large number of software tests is an important step in software development. In the process of software testing, programmers often need to locate the software faults found. Traditional software fault detection and localization technologies are divided into two categories according to whether the process needs to run software: static fault detection based on static analysis and dynamic fault detection based on testing. The static analysis method is mainly based on the syntax and semantics of the programming language to analyze the dependency relationship between the software structure and the program entity, so as ...
