Virtual Terminals

When CA Verify for CICS runs a test stream, it allocates virtual terminals for each terminal in the test stream. It uses terminal information, stored when the test stream was logged, to synchronize the status of the virtual terminal with the real terminal used in logging. Using virtual terminals:

• Saves system resources
• Does not restrict testing to the number of physical terminals available
• Does not affect users who need the real terminals

However, if you are using VTAM virtual terminals, you can specify that test streams be run with real terminals instead. Using real terminals may be useful when you are performing large-volume controlled tests. See Select a Terminal later in this chapter for instructions on running with real terminals.
