Problems solved by technology

But determining whether a bug detected by a static source code is a real bug takes a lot of effort
For the automatic detection and repair of software errors, the following solutions exist in the prior art, that is, do not care about the internal execution of the program to be tested, randomly generate use cases, and observe whether the program output is in line with expectations, but its defect is that the code coverage is low , so its error detection capability is limited

Abstract

The invention provides an automatic detection and correction method of codes; the method comprises: monitoring a program to be detected; inputting error constraints to path constraint conditions when a key command is executed; detecting erred error constraints on a current operating path, and marking the error constraints; judging whether an external function has a corresponding function model according to its function name; if yes, judging whether parameters of the function are associated with signs; if yes, executing the function model, tracking sign transfer, and performing actual execution. The automatic detection and correction method of codes has the advantages that error location efficiency is improved at the premise of not decreasing code coverage, and a code error seeking process is optimized.

Description

technical field [0001] The invention relates to software debugging, in particular to a code automatic detection and correction method. Background technique [0002] Software debugging occupies a considerable overhead in the overall software development. Although software companies have invested heavily in software debugging, serious errors will still be found after the software is released. Patching software bugs after release can still cause serious financial losses. Research has found that most of the software-related security incidents are caused by software errors introduced during the design or coding phase. But determining whether a bug detected by a static source code is a real bug takes a lot of effort. For the automatic detection and repair of software errors, the following solutions exist in the prior art, that is, do not care about the internal execution of the program to be tested, randomly generate use cases, and observe whether the program output is in line ...
