Problems solved by technology

These technical solutions will mark the text modification that would not have any impact on the running results of the program as differences, causing developers to manually find the semantic difference that really affects the running results among the large number of identified differences

Abstract

The invention relates to a method and a device for identifying semantic difference between source code versions. In one embodiment of the invention, a method for identifying the semantic difference between the source code versions is provided, comprising: respectively obtaining first debugging information of a first source code version and second debugging information of a second source code version; comparing the first debugging information with the second debugging information, and determining whether a second function matched with a first function in the first source code version exists in the second source code version; and identifying the semantic difference based on the determined result. In one embodiment of the invention, a device for identifying the semantic difference between the source code versions is provided. By adopting the method and the device provided by the invention, the semantic difference between the source code versions can be identified quickly and accurately.

Description

technical field [0001] Embodiments of the invention relate to software development, and more particularly, to methods and apparatus for identifying semantic differences between source code versions during software development. Background technique [0002] With the increase of user needs, the functions of computer software are also becoming more and more complex. During the software development cycle, different source code versions in various development stages need to be tested frequently. Regression testing refers to re-testing after modifying the old code to confirm that the modification does not introduce new errors or cause errors in other codes. As an important part of software development, regression testing occupies a large proportion of workload in the whole software development process. Generally speaking, developers step through each function in the software design and ensure the correctness of the source code based on regression testing. [0003] For example, ...
