Software testing device and method based on parameterization

The invention discloses a software testing device and method based on parameterization, and relates to the technical field of software testing. According to the main technical scheme, an editable use case list and an editable variable list associated based on a'use case input parameter 'attribute field in the use case list are provided and displayed by utilizing a front-end module; a user-defined use case input parameter is obtained based on the use case list, user-defined parameter configuration on variables is obtained based on the variable list, modification executed by the two lists is independent of each other, and the situation of redundant and repeated modification is avoided; then, a data engine module is utilized to generate use case input parameter preview data corresponding to each use case ID based on the flexibly modified use case input parameter and variable list, so that a storage module stores the use case input parameter and the use case input parameter preview data corresponding to the same
