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 client-server 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.
