What is validictation?

Validation is the process of evaluating whether something is valid, legal, or satisfactory. In the context of software engineering, validation is the process of evaluating whether software is compliant with its requirements, standards, and specifications.

Validation is part of the software development life cycle (SDLC) and is typically performed after software testing has been completed. It is important to note that validation is not the same as testing, as testing is the process of identifying defects, while validation is the process of ensuring that the software meets its requirements.

Validation techniques include:

* Code reviews

* Unit testing

* Functional testing

* Performance testing

* Security testing

* Usability testing
