Abstract: Systems and methods for gathering, organizing and executing test cases irrespective of the language or format employed. Implementation of the present invention takes place in association with a harness that is interposed between a software package to be tested and a program module. Programming code comprising a connector interfaces the harness with the program module in order for the harness to receive a hierarchy that comprises one or more test cases, test suites and/or test modules. The harness traverses the hierarchy and executes test cases selected by a user on the developed software package. Therefore, in accordance with the present invention, individuals testing the software package can select any desired test case format (programming language, machine architecture, operating system, test sequence, etc.) that satisfies the demands of the developed software package, and the harness will gather, organize, and execute the developed test case(s) irrespective of the language or format employed.
