An automated software testing system allows automated test script generation with fully parameterized scripts, execution, and result correlation in a recreatable and adaptable manner. A software Application Under Test (AUT) is identified and includes a process having Graphical User Interface (GUI) windows, objects and data elements. A test thread tree is generated corresponding to the windows, objects and data elements in the process. A grid is generated to enumerate test cases indicative of the windows, objects and data elements in the AUT process. Also generated is a parameterized script indicative of each of the test cases and having string values instead of hard-coded data of the AUT process. A global change manager automates modifying in the grid, data object attributes across multiple scripts. A Scenario view or data generation member generates Test Descriptions and automates documentation of test cases based on the script. The script is executed to apply each of the test cases to the AUT and receive a response for each test case from the AUT.
