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 a code exception locating and processing method. The method comprises the steps of generating a use case and then inputting an error constraint to a path constraint condition; solving a new path constraint condition and generating a use case triggering software errors; performing modeling on an external function and monitoring symbol transmission caused by the external function; and locating code errors through the symbol transmission. According to the code exception locating and processing method provided by the invention, on the premise of not reducing the code coverage rate, the error locating efficiency is improved, and a code error search process is optimized.

Description

technical field [0001] The invention relates to software debugging, in particular to a method for locating and processing abnormal codes. 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 li...
