A method and system for improving automated software testing is provided. The method includes identifying software elements of a software test specification executed by a hardware device of an IT system. Existing software objects associated with a software module for testing are mapped to the identified software elements and with physical operational values of the software module. The identified software elements of the software test specification and associated software parameters are verified and software values of the identified software elements are extracted. The software values are executed with respect to a library database and the software test specification in executed with respect to the software module. In response, software module test software for operationally testing software modules and associated hardware devices is generated resulting in improved operation of the software modules and associated hardware devices.
