verification and validation. Verification is the process of evaluating whether a product, system or software meets the specified requirements and standards. This is done by reviewing documents, code, and conducting static testing such as walkthroughs and inspections.
Validation, on the other hand, is the process of evaluating whether the software meets the actual user requirements and meets the intended use of the software. This is done by conducting dynamic testing such as functional testing, integration testing, and system testing.
In other words, verification checks whether the software is built right, while validation checks whether the right software is built.
By understanding the difference between verification and validation, software testers and developers can ensure that the software is both built correctly and meets the intended use and user requirements.
