Abstract

The invention relates to a fuzzy testing method based on a deterministic strategy and coverage guidance. The fuzzy testing method comprises the following steps: compiling and instrumenting a tested program; aiming at a test result of a seed variation generation sample, optimizing a seed variation scheduling model according to a deterministic strategy, and performing seed compiling selection through instrumentation feedback information; and when the code coverage rate of the tested program is not increased any more and no new vulnerability is generated within the set time, the fuzz test is stopped. The invention further relates to a fuzzy testing tool based on the deterministic strategy and coverage guidance. The fuzzy testing method and tool based on the deterministic strategy and the coverage guidance aim at solving the problem that traditional fuzzy testing has great effect differences for different software.

Description

technical field [0001] The invention relates to the technical field of software security testing, in particular to a fuzzy testing method and tool based on deterministic strategy and coverage guidance. Background technique [0002] In recent years, under the background of the "Internet +" era, with the continuous development of the Internet industry, the number of various types of software on the market has exploded. In addition, due to the introduction of agile, DevOps and other development modes in software development and the development of data governance and artificial intelligence applications, the software delivery cycle is gradually shortened, and the technical complexity is constantly increasing, which makes the current software manual testing more and more difficult. Investment and application of automated testing technology. In addition, the previous testing often focused on the testing requirements of software functions, and often ignored the evaluation of softw...
