What is Verification?The verifying process includes checking documents, design, code, and program. What is Validation?Validation is a dynamic mechanism of Software testing and validates the actual product. Verification vs Validation: Key Difference Verification Validation The verifying process includes checking documents, design, code, and program It is a dynamic mechanism of testing and validating the actual product It does not involve executing the code It always involves executing the code Verification uses methods like reviews, walkthroughs, inspections, and desk- checking etc. It uses methods like Black Box Testing, White Box Testing, and non-functional testing Whether the software conforms to specification is checked It checks whether the software meets the requirements and expectations of a customer It finds bugs early in the development cycle It can find bugs that the verification process can not catch Target is application and software architecture, specification, complete design, high level, and database design etc. Target is an actual product QA team does verification and make sure that the software is as per the requirement in the SRS document. With the involvement of testing team validation is executed on software code. It comes before validation It comes after verification Example of verification and validation In Software Engineering, consider the following specification A clickable button with name Submet Verification would check the design doc and correcting the spelling mistake. Otherwise, the development team will create a button like So new specification is A clickable button with name Submit Once the code is ready, Validation is done. A Validation test found – Owing to Validation testing, the development team will make the submit button clickable
