Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] The current research on software fault location is trying to use a certain calculation method to predict the error-prone location of the program and recommend it to the user. However, through research and analysis, it is found that some of these studies ignore the factors of human participation, resulting in the effect of fault location. Not as expected. This method eliminates the fault location method of perfect understanding assumptions, takes the artificial historical debugging track as the analysis object, finds out the commonality, and proposes a label-based key information identification method, which is recommended to users as a recommendation basis.

[0034] Such as figure 1 As shown, the present invention implements a monitoring plug-in for monitoring and debugging personnel's behavior track. When a user generates a debugging behavior, the m...

Abstract

The invention discloses a software fault location method for removing the perfect understanding hypothesis. The method realizes the Eclipse monitoring plug-in and saves the debugging information of auser in a MYSQL database, and the information includes the debugging behavior information of the user and the program context scenario information. Through analysis of this information, it is found that the debugging trajectory of the same fault debugger is related to each other, the key information in debugging is given by referring to the key class, the key information identification method based on label is adopted as a general recommendation rule, and the key information is directly fed back to the user's integrated development environment as the recommendation content, so the debugger isassisted to locate the fault.

Description

technical field [0001] The invention relates to a software fault location method, especially when the assumption of perfect understanding is removed, key information is defined and identified, and the critical degree is calculated and recommended to users to assist debuggers to locate faults. Background technique [0002] For software debugging, how to find the key information that can be used for recommendation is the most important part of the application of recommendation system in fault location. This motivated Lisa Burnell and Eric Horvitz to investigate how logical and probabilistic reasoning can be used to support software debugging, and they describe a method based on logical composition and probabilistic reasoning [18] , can be used to identify the source and location of faults in complex software. This method can be used to diagnose errors at runtime in the Saber system, which is the largest time-sharing reservation system in the world. The verification results sho...
