Verification & Validation

Verification and Validation are two terms that are often used in the context of software testing, and they refer to two distinct but related processes:

Verification: Verification is the process of ensuring that a software product or system meets its specified requirements and specifications. It involves checking that the software has been built correctly, and that it meets the design and functional specifications that have been established for it. In other words, verification is focused on making sure that the software has been built according to the requirements.

Validation: Validation, on the other hand, is the process of ensuring that a software product or system meets the needs and expectations of its intended users or stakeholders. It involves checking that the software meets the business or user needs, and that it is fit for its intended purpose. In other words, validation is focused on making sure that the right software has been built, and that it meets the needs and expectations of its users.

To summarize, verification is about checking that the software has been built correctly according to the requirements, while validation is about checking that the right software has been built to meet the needs of its users. Both verification and validation are important processes in software testing, and they are often performed together to ensure that the software meets all of the necessary requirements and standards.
