In-Depth Information
Decision table:
A table showing combinations of inputs and/or stimuli (causes)
with their associated outputs and/or actions (effects), which can be used to design
test cases.
Decision table testing:
A black box test design technique in which test cases are
designed to execute the combinations of inputs and/or stimuli (causes) shown in a
decision table.
Decision testing:
A white box test design technique in which test cases are designed
to execute decision outcomes.
Decision outcome:
The result of a decision (which therefore determines the
branches to be taken).
Defect:
A flaw in a component or system that can cause the component or system
to fail to perform its required function (e.g., an incorrect statement or data defini-
tion). A defect, if encountered during execution, may cause a failure of the compo-
nent or system.
Defect density:
The number of defects identified in a component or system divided
by the size of the component or system (expressed in standard measurement terms—
for example, lines of code, number of classes, or function points).
Defect Detection Percentage (DDP):
the number of defects found by a test phase,
divided by the number found by that test phase and any other means afterwards.
Defect management:
The process of recognizing, investigating, taking action and
disposing of defects. It involves recording defects, classifying them and identifying
the impact. [IEEE 1044]
Defect management tool:
A tool that facilitates the recording and status tracking
of defects. They often have workflow-oriented facilities to track and control the
allocation, correction, and retesting of defects and provide reporting facilities. See
also
incident management tool
.
Defect masking:
An occurrence in which one defect prevents the detection of
another. [IEEE 610]
Defect report:
A document reporting on any flaw in a component or system that can
cause the component or system to fail to perform its required function. [IEEE 829]
Defect tracking tool:

defect management tool
.
Definition-use pair:
The association of the definition of a variable with the use of
that variable. Variable uses include computational (e.g., multiplication) or to direct
the execution of a path (“predicate” use).
Deliverable:
Any (work) product that must be delivered to someone other than the
(work) product's author.
Delivery manager:
Person who manages outsourced projects from customers from
service provider's side. A delivery manager can manage all projects belonging to a
specific area (e.g., manufacturing, customer relationship management). Delivery
manager is distinct from project managers as he is the single point contact for the
customer from service provider's side.
