Embodiment Construction

[0024] In order to improve the efficiency of software error location, the present invention provides a software error location device, the device includes a processor, the processor is used to execute instructions to implement the software error location method of the present invention, the following in conjunction with the accompanying drawings and embodiments, the The method is described in detail.

[0025] The overall flowchart of the method is as follows figure 1 shown.

[0026] First, if figure 2 As shown, with the source code of the test case driver, under the Ubuntu 12.04.2 operating system and the gcc-4.6.3 compiler, use the Gcov component of gcc to obtain the execution path information of the program, and obtain the corresponding program execution through the test language As a result, a successful execution path and a failure execution path are obtained.

[0027] Then, in order to avoid the impact of accidental correctness on software error location, the improved...

Abstract

The invention relates to a software error positioning method and device. The method comprises the steps that through a source code of a testing case driving program, execution path information and a corresponding execution result of the program are acquired, wherein a successful execution path and a failure execution path are involved; an NJW spectral clustering algorithm is adopted for conductingclustering division on the execution path information of the program, an accidental correctness testing case is identified, and the identified accidental correctness testing case is removed; the suspicious degrees of codes are calculated, and a highly-suspicious code of which the suspicious degree is higher than a set suspicious degree threshold value is acquired; an association code associated with the highly-suspicious code is mined on the failure execution path; with the mined association code as a code inspection object, software error positioning is conducted. The software error positioning method has low false report rate and missing report rate on accidental correctness testing case identification, the accuracy rate of software error positioning is increased, and the efficiency ofsoftware error positioning is improved.

Description

technical field [0001] The invention belongs to the technical field of software analysis and testing, and in particular relates to a software error location method and device. Background technique [0002] Software has become an important part of the modern information society and an important factor to ensure national information security and the healthy development of the software industry. The improvement of software quality can improve people's life and work, and has a significant role in promoting the development of national economy and information industry. As the scale and complexity of software increase, the frequency of software errors increases rapidly, and software errors may cause great losses or disasters to human beings. [0003] Software testing is the process of executing the program in order to display the errors existing in the program, which is an important link in the software life cycle; software debugging is the process of finding and repairing errors....
