Software validation checks that the software product satisfies or fits the intended use (high-level checking), i.e., the software meets the user requirements, not as specification artifacts or as needs of those who will operate the software only; but, as the needs of all the stakeholders (such as users, operators, administrators, managers ...
Verification is intended to check that a product, service, or system meets a set of design specifications. [6] [7] In the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service, or system, then performing a review or analysis of the modeling results.
It is distinct from software quality assurance which encompasses processes and standards for ongoing maintenance of high quality of products, e.g. software deliverables, documentation and processes - avoiding defects. Whereas software quality control is a validation of artifacts compliance against established criteria - finding defects.
Software verification is a discipline of software engineering, programming languages, and theory of computation whose goal is to assure that software satisfies the expected requirements. Broad scope and classification
In the prototyping stage, engineers create actual working samples of the product they plan to produce. Engineering verification testing (EVT) is used on prototypes to verify that the design meets pre-determined specifications and design goals.
The software development process is a typical application of Fagan inspection. As the costs to remedy a defect are up to 10 to 100 times less in the early operations compared to fixing a defect in the maintenance phase, [1] it is essential to find defects as close to the point of insertion as possible.
It ensures the continuing function of a piece of software under unforeseen circumstances. Defensive programming practices are often used where high availability, safety, or security is needed. Defensive programming is an approach to improve software and source code, in terms of: General quality – reducing the number of software bugs and problems.
Data validation is intended to provide certain well-defined guarantees for fitness and consistency of data in an application or automated system. Data validation rules can be defined and designed using various methodologies, and be deployed in various contexts. [1]
