Problems solved by technology

[0007] The problem to be solved by the present invention is: at present, the positioning and repairing of software defects by developers is still mainly based on experience, which is easily affected by subjective ideas. Using the objective information of the program for defect positioning and visual guidance can help developers locate faster and more accurately until software bugs are fixed

Embodiment Construction

[0039] The present invention is a method for guiding software defects of programmers based on frequency spectrum positioning and visualization, which aims to provide developers with better defect positioning and repair guidance, and at the same time make up for inaccuracies that may be caused by subjective factors such as personal experience Even wrong.

[0040] The core technology of the present invention is to combine static scanning and dynamic execution, use the collected two kinds of data to establish a model and apply it to frequency spectrum positioning, obtain calculation of suspicious values ​​and visualize them.

[0041] First, static analysis is used to obtain the control flow graph structure of the program. As the basis of the subsequent analysis of the present invention and the display of the objective structure of the program, the control flow graph plays a crucial supporting role. Next, use dynamic execution to use unit test cases to test and execute the source ...

Abstract

The invention discloses a method for positioning software defects on basis of frequency spectrum positioning and visualization, and aims at providing better defect positioning and restoration guidance for developers and remedying the inaccuracy and mistakes caused by subjective factors such as personal experiences and the like. The method comprises the following steps of: obtaining a control flow diagram on the logic of a program by utilizing static analysis; applying a coverage rate, for a program, of a test case obtained through dynamic execution and an own execution result to frequency spectrum positioning; carrying out calculation to obtain the possibility that a program unit comprises defects; distinguishing suspicious degrees through sorting, discretization and grouping; and finally realizing the suspicious degrees on a development tool in a visualization manner.

Description

technical field [0001] The invention belongs to the field of computer technology, relates to the field of software engineering in IT technology, is used to guide programmers on software defects, and is a method based on frequency spectrum positioning and visualization. Background technique [0002] With the increasing popularity of software, software quality has become the focus of people's attention. Among the many methods to ensure software quality, the behavior of developers acts as the first line of defense. Developers need to use testing to ensure the correctness of the software they develop, and when a fault occurs, debugging becomes a way to find a solution to the software defect. [0003] Debugging includes the process of locating software defects and repairing them. The most important and difficult step is to locate the location of the defect. Traditional software error location is manually performed by developers, and these techniques include running the software...
