A device response template generator software program includes an interactive graphical-user-interface (GUI) for sending commands to devices under test and to capture and display the command responses. The GUI enables patternization of the command response to that the information contained in the response can be read, in the form of variable values, automatically, during subsequent execution of the commands by the same device or a group of devices. These values of the variables may be analyzed and may also be sent to other running testing scenarios.
