Abstract

Described is a software testing facility which allows the ability to display mixed data types on a single monitor screen during code testing. The facility allows the user to simultaneously display test source, test case log data and Fax page images.

Mixed Data Type Display Interface

       Described is a software testing facility which allows the
ability to display mixed data types on a single monitor screen during
code testing. The facility allows the user to simultaneously display
test source, test case log data and Fax page images.

      In prior art, the ability to display mixed data type
information, such as text and images, during the testing of
application programs which run in a multi-protocol interactive system
environment has been difficult.  This is primarily due to the
complicated control and lack of flexibility inherent in displaying
mixed data types during software testing.  So as to foster
productivity and to provide verification of a Fax test system, an
easily controlled man-machine interface with the capability for both
textual and image data presentation was required.

      The concept described herein operates in conjunction with
inbound controller testing (ICT) systems for the testing of inbound
Fax con troller (IFC) devices.  An ICT system simulates a host system
that controls an IFC.  The IFCs act as a gateway-concentrator for Fax
documents into a host system controlled store and forward FAX
service. The ICT system and the IFC compresses Fax pages and also
exchanges various command, response, and status message
communications via a TCP/IP protocol (protocol of the FTP Software
Corporation) across an Ethernet local area network (LAN).

      The difficulty in testing within a multi-protocol interactive
environment that had intermixed text and image data prompted the
necessity for a multi-data type, simply controlled, and easily
understood tester interface.  The concept described herein combines
items such as:
      -    Indication and display of each application source code
line as it executes.
      -    Low overhead textual screen layout of mixed windowed and
scrolled data.
      -    Software decompression/compression of bit image under
keyboard control.
      -    Single keystroke control of all textual and bit image
screens.

      The concept concentrates on satisfying the simultaneous display
of types of test data as follows:
      -    Test language source as it executes
      -    Test case textual log data
      -    Fax page images
The concept is composed of the following three segments as follows:
     1. Textual mode cathode ray tube (CRT) screen (windowed and
scrolled).
     2. Bit image mode CRT screen.
     3. Single keystroke controls.

      Fig. 1 shows the features of the textual mode CRT screen
layout, and Fig. 2 shows the features of the bit image mode CRT
screen layout.
