technology. This measurement may be used as a basis for the measurement of pro-
ductivity, the estimation of the needed resources, and project control.
Functional integration:
An integration approach that combines the components
or systems for the purpose of getting a basic functionality working early. See also
integration testing
.
Functional requirement:
A requirement that specifies a function that a compo-
nent or system must perform. [IEEE 610]
Functional test design technique:
Procedure to derive and/or select test cases based
on an analysis of the specification of the functionality of a component or system
without reference to its internal structure. See also
black box test design technique
.
Functional testing:
Testing based on an analysis of the specification of the func-
tionality of a component or system. See also
black box testing
.
Functionality:
The capability of the software product to provide functions that
meet stated and implied needs when the software is used under specified condi-
tions. [ISO 9126]
Functionality testing:
The process of testing to determine the functionality of a
software product.
G
Glass box testing:
See
white box testing
.
H
Heuristic evaluation:
A static usability test technique to determine the compliance
of a user interface with recognized usability principles (the so-called heuristics).
High-level test case:
A test case without concrete (implementation level) values for
input data and expected results. Logical operators are used; instances of the actual
values are not yet defined and/or available. See also
low-level test case
.
Horizontal traceability:
The tracing of requirements for a test level through the
layers of test documentation (e.g., test plan, test design specification, test case speci-
fication and test procedure specification, or test script).
I
Impact analysis:
The assessment of change to the layers of development documen-
tation, test documentation, and components, in order to implement a given change
to specified requirements.
Incident:
Any event occurring that requires investigation. [IEEE 1008]
Incident logging:
Recording the details of any incident that occurred (e.g., dur-
ing testing).
