Which of the following types of testing would determine whether a new or modified system can operate in its
target environment without adversely impacting other existing systems?

A.
Parallel testing

B.
Pilot testing

C.
Interface/integration testing

D.
Sociability testing

Explanation:
The purpose of sociability testing is to confirm that a new or modified system can operate in its target
environment without adversely impacting existing systems. This should cover the platform that will perform
primary application processing and interfaces with other systems, as well as changes to the desktop in a clientserver or web development. Parallel testing is the process of feeding data into two systems-the modified
system and an alternate system-and comparing the results. In this approach, the old and new systems operate
concurrently for a period of time and perform the same processing functions. Pilot testing takes place first at
one location and is then extended to other locations. The purpose is to see if the new system operates
satisfactorily in one place before implementing it at other locations. Interface/integration testing is a hardware or
software test that evaluates the connection of two or more components that pass information from one area to
another.The objective is to take unit-tested modules and build an integrated structure.
