Fuzzy test method and device, electronic equipment and storage medium

The invention relates to a fuzzy testing method and device, electronic equipment and a storage medium, and relates to the technical field of software testing. The method comprises the steps that running information of an application program is obtained, a local library interface function calling sequence in the running process is intercepted, and data information of a local library interface function in the calling sequence is recorded; and performing a fuzzy test on the local library interface function according to the operation information and the data information to obtain a defect report of the local library interface function. According to the method and the device, the local library interface function is adaptively intercepted, so that the test coverage of the local library code is improved, the code defect and security vulnerability of the local library can be effectively detected, and the reliability and security of the mobile terminal application program are enhanced. 本公开关于一种模糊测试方法、装置、电子设备及存储介质，涉及软件测
