Abstract

Validation entails methods to ascertain that the system built is the right one, whereas verification implies reaching a certain level of confidence in the correctness of the software system. Although there is substantial grey area in-between, validating a software system reduces to determining whether it meets the specified requirements. On the other hand, verification involves establishing that the software will work properly, both in terms of functionalities and in terms of satisfying certain properties, such as safety properties. Object-oriented software development brings about a new set of concepts, such as inheritance, polymorphism, and dynamic binding, calling for the emergence of a new set of analytical methodologies.
