Software Validation And Testing. It is carried out at the end of the SDLC. Software experts have come up with two broad approaches to verification.
The business requirement logic or scenarios have to be tested in detail. Dynamic verification is performed during the execution of software and dynamically checks its behaviour. Software validation testing is an important part of the software development lifecycle SDLC apart from verification debugging and certification.
Static verification is the process of checking that software meets requirements by inspecting the code before it runs.
After verification testing validation testing takes place. As Wikipedia defines it. Software validation and other related good software engineering practices discussed in this guidance are a principal means of avoiding such defects and resultant recalls. It may also be referred to as software quality control.
