Verification and validation are two important processes in software testing that help ensure the quality of the software product. Here are the key differences between verification and validation based on the search results:
Verification:
- It is the process of checking that software achieves its goal without any bugs.
- It is the process to ensure whether the product that is developed is right or not.
- It verifies whether the developed product fulfills the requirements that we have.
- It is static testing.
- It includes checking documents, design, codes, and programs.
- It does not include the execution of the code.
- Methods used in verification are reviews, walkthroughs, inspections, and desk-checking.
Validation:
- It is the process of checking whether the software product is up to the mark or, in other words, the product has high-level requirements.
- It is the process of checking the validation of the product, i.e., it checks whether what we are developing is the right product.
- It is dynamic testing.
- It includes testing and validating the actual product.
- It includes the execution of the code.
- Methods used in validation are Black Box Testing, White Box Testing, and non-functional testing.
- It involves activities like unit testing, integration testing, system testing, and user acceptance testing.
In summary, verification is about building the product right, while validation is about building the right product. Verification is static testing, while validation is dynamic testing. Verification checks documents, design, codes, and programs, while validation tests and validates the actual product. Verification does not include the execution of the code, while validation includes the execution of the code.
