An Approach to Testing Real-Time Processing of a Computer-Based Information

An approach to testing real-time processing of a computer-based information system is known as the integrated test facility (ITF) technique.This approach involves:

A) testing the computer hardware at the same time as test transactions enter the real-time system.
B) validating as well as editing all input transactions entering the real-time system.
C) running monthly activities simultaneously with current transactions so that the two are integrated in the result of the test.
D) setting up a small set of records for a fictitious entity in the master files and then processing dummy transactions against the fictitious entity.
