Test Case A set of test inputs, execution conditions, and expected results developed for a particular
objective, such as to test a particular program path or to verify compliance with a specific
requirement.
Testing The process of operating a system under specified conditions, observing or recording the
results, and making an evaluation of some aspect of the system.
Test Procedure (a) Specified way to perform a test.

TERM
DESCRIPTION
(b) Detailed instructions for the set-up and execution of a given set of test cases, and
instructions for the evaluation of results of executing the test cases.
Traceability Ability to trace the history, application or location of an entity by means of recorded
identifications.
Transient
Error
An error that occurs once, or at unpredictable intervals.
Validation The process of evaluating a system (and subset), during or at the end of the development
process to determine whether it satisfies specified requirements. Conformance to requirements
is no total assurance of acceptable risk.
Verification The process of evaluating a system (and subset) to determine whether the products of a given
development phase satisfy the conditions imposed at the start of the phase.
Volatile
Memory
Memory that requires a continuous supply of power to its internal circuitry to prevent the loss
