Under real world conditions, SAPGUI-application users submit unpredictable combinations of data into forms. One goal of effective SAPGUI application testing is to emulate such irregular and diverse user behavior in test scripts.
You can customize the user-input data that is entered into forms during testing with the Parameter Wizard. The Parameter Wizard lets you specify values to be entered into form fields, enabling your test scripts to be more realistic by replacing recorded user input data with randomized, parameterized data.
After you create a new parameter, that parameter is added to the existing parameters and is available for further customizations.
Initiate a Try Script run with the random variable function in your test script to confirm that the script runs without error.
