Incorporating User Defined Display Partition Recognition into a Non-invasive Automation of Workstation Testing

       Disclosed is a PC-based test tool that is capable of
driving emulated Keyboard and Mouse data to multiple workstations
through an Intelligent Response Interface Element (IRIE).  In this
way it simulates the activity of human operators on one to eight
workstations.

      Its unique feature is the ability to non-invasively monitor and
obtain a signature of not only the entire display of the machine
under test, but especially to limit the area of display to be
examined to "partitioned" areas of that display.  This feature is
unique for the following reasons:
      1.   It allows the computer system tester to define and examine
only those areas of the display that are of interest when analyzing
system software function.
      2.   By rapidly monitoring successive selected parts of the
tested display, several areas of information of interest can be
checked without impeding the flow of the automated test or the
activity on other workstations attached to the test driver.
      3.   Portions of the tested display screen may be selected for
exclusion from the area to be recognized, thus isolating those areas
which may be subject to unpredictable change, such as flashing cursor
or messages.
      4.   The system under test is monitored in a non-invasive way,
in that any hardware attached to it is attached passively, with no
electrical perturbation.  Additionally, no test software is resident
on the system under test, thus eliminating the likelihood of
impacting or being impacted by the software applications on the
tested system.  Hardware monitoring is accomplished by capturing
display data directly from the video signals and by driving the
peripheral inputs for Mouse and Keyboard through a specially designed
interface element (IRIE).
THE DISPLAY CONTENT MONITOR (DCM):

      Interpretation of the contents of the display image of a
workstation under test is based on extracting the display dot data
and making it available to the monitoring computer.  The high data
rates and serial nature of video display data rule out real-time
monitoring by conventional computers.
