Abstract

The invention relates to a fuzzy test method and device based on text recognition. The method comprises the steps that a to-be-processed text is processed through a test data generation network, a first round of test data set for conducting a fuzzy test on a tested object is generated, the test data generation network comprises a text recognition sub-network and a data generation sub-network, andthe tested object is an executable object corresponding to the to-be-processed text; according to the first round of test data set and the test data generation network, multiple rounds of fuzzy test is performed on the tested object to obtain an intermediate test result of the multiple rounds of fuzzy test, the intermediate test result comprising a code coverage rate and an operation state of thetested object; and when the code coverage rate of the Nth round of fuzzy test is greater than or equal to a preset coverage rate threshold, an intermediate test result of the Nth round of fuzzy test is determined as a final test result. According to the embodiment of the invention, the code coverage rate and mining depth of the fuzzy test can be improved, and the effectiveness of the fuzzy test isenhanced.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular to a text recognition-based fuzz testing method and device. Background technique [0002] Fuzz testing is a software testing technique whose core idea is to input automatically or semi-automatically generated random data into the target system to find possible errors in the target system. Fuzz testing is commonly used to detect security vulnerabilities in software or computer systems. Among many software vulnerability mining methods, fuzz testing is a relatively mature one. However, fuzz testing generally has problems such as insufficient mining depth and low code coverage, which makes fuzz testing less effective. Contents of the invention [0003] In view of this, the present disclosure proposes a fuzzing technical solution based on text recognition. [0004] According to an aspect of the present disclosure, a text recognition-based fuzz testing method is provided, t...
