Software verification and validation is the process of investigating that a software system satisfies specifications and standards and it fulfills the required purpose.
More specifically, software verification testing is the process of checking that a 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.
Software verification is a kind of software testing that is called static testing, a software testing technique in which the software is tested without executing the code. Methodology involved in software verification testing include:
- Inspections
- Reviews
- Walkthroughs
- Desk Checking
Software validation, on the other hand, is the process of checking whether the software product is up to the mark or in other words product has high level requirements. This is all about checking the validation of product. For example, software validation checks that what is being developed is the right product.
Software validation requires a kind of software testing that is called dynamic testing, a software testing method used to test the dynamic behavior of software code. Methodology involved in software validation testing includes:
- Black box testing
- White box testing
- Unit testing
- Integration testing
Software verification testing can find the bugs in the early stage of the development. The goal of verification is application and software architecture and specification.
In software validation testing, testers look for bugs that could not be found by the verification process. It consists of execution of program and is performed by computer.
