Object Oriented Analysis and Design

Notes 9.2.1 Approaches to Systems Testing

Test is done according to
how it has been built

what it should do
It includes four quality measures:
Correspondence: It measures how well delivered system matches needs of operational
environment, as described in original requirements statement

Validation: It is defined as the task of predicting correspondence.

Did u know? True correspondence is only determined after system is in place.
Correctness: It measures consistency of product requirements with respect to design
specification

Verification: It is the exercise of determining correctness (correctness objective => always
possible to determine if product precisely satisfies requirements of specification)
