--- description: Difference Between Verification and Validation in Software Testing with Example: Learn the difference between Verification Vs. Validation. title: Differences Between Verification and Validation image: https://www.guru99.com/images/blog/submet.png --- [Skip to content](#main) ## Key Difference between Verification vs Validation * Verification process includes checking documents, design, code, and program, whereas Validation process includes testing and validation of the actual product. * Verification does not involve code execution, while Validation involves code execution. * Verification uses methods like reviews, walkthroughs, inspections, and desk-checking, whereas Validation uses methods like [black box testing](https://www.guru99.com/black-box-testing.html), white box testing, and non-functional testing. * Verification checks whether the software confirms a specification, whereas Validation checks whether the software meets the requirements and expectations. * Verification finds the bugs early in the development cycle, whereas Validation finds the bugs that verification can not catch. * Comparing validation and verification in software testing, the Verification process targets software architecture, design, database, etc., while the Validation process targets the actual software product. * Verification is done by the QA team, while Validation is done by the involvement of the testing team with the QA team. * Comparing Verification vs Validation testing, the Verification process comes before validation, whereas the Validation process comes after verification. [](https://www.guru99.com/images/verification-and-validation.png) Verification vs Validation ## What is Verification in Software Testing? **Verification in Software Testing** is a process of checking documents, design, code, and program in order to check if the software has been built according to the requirements or not. The main goal of verification process is to ensure quality of software application, design, architecture etc. The verification process involves activities like reviews, walk-throughs and inspection. ## What is Validation in Software Testing? **Validation in Software Engineering** is a dynamic mechanism of testing and validating if the software product actually meets the exact needs of the customer or not. The process helps to ensure that the software fulfills the desired use in an appropriate environment. The validation process involves activities like unit testing, integration testing, system testing and user acceptance testing. ## Difference Between Verification and Validation in Software Testing Here is the main difference between Verification and Validation in Software Testing: | 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](https://www.guru99.com/white-box-testing.html), 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 | ### RELATED ARTICLES * [ How To Become a Software Tester (Career Path) ](https://www.guru99.com/software-testing-career-complete-guide.html "How To Become a Software Tester (Career Path)") * [ What is SOA Testing?
