LATEST UPDATE -2026- 100+ QUESTIONS AND VERIFIED
ANSWERS ALL THE BEST
System testing
The bringing together for testing purposes of all the programs that a system
comprises. Programs are typically integrated in a top-down, incremental fashion.
Parallel installation
Running the old information system and the new one at the same time until
management decides the old system can be turned off.
Single-location installation
Trying out a new information system at one site and using the experience to
decide if and how the new system should be deployed throughout the
organization.
Phased installation
Changing from the old information system to the new one incrementally, starting
with one or a few functional components and then gradually extending the
installation to cover the whole new system.
Stub testing
A technique used in testing modules, especially where modules are written and
tested in a top-down fashion, where a few lines of code are used to substitute for
subordinate modules.
Testing harness
, 2
An automated testing environment used to review code for errors, standards
violations, and other design flaws.
Acceptance testing
The process whereby actual users test a completed information system, the end
result of which is the users' acceptance of it once they are satisfied with it.
Alpha testing
User testing of a completed information system using simulated data.
Beta testing
User testing of a completed information system using real data in the real user
environment.
Installation
The organizational process of changing over from the current information system
to a new one.
Direct installation
Changing over from the old information system to a new one by turning off the
old system when the new one is turned on.
System documentation
Detailed information about a system's design specifications, its internal workings,
and its functionality.
Internal documentation
System documentation that is part of the program source code or is generated at
compile time.
External documentation
System documentation that includes the outcome of structured diagramming
techniques such as data-flow and entity-relationship diagrams.
User documentation
