As we can see that the name shows that, a functional test is a kind of black box testing that is performed to confirm that the functionality of an application or system is behaving as expected. Functional testing is done to verify all the functionality of a product.
FUNCTIONAL TESTING is also known a type of software testing whereby the system is tested against the functional requirements/specifications. Functions (or features) are tested by feeding them input and examining the output. Functional testing ensures that the requirements are properly satisfied by the application.Functional testing is performed using the functional specification provided by the client and verifies the system against the functional requirements. Non-Functional testing checks the Performance, reliability, scalability and other non-functional aspects of the software system.Examples of functional testing are Smoke testing, Sanity testing, Regression testing, Usability testing.
Answer:
Functional testing is type of testing done against the business requirements of application.it is black box type of testing.
verification is a process of evaluating the intermediary work products of a software development life cycle to check if we are in the right of creating the final product.
Functional testing and verification attempts to confirm that the design meets requirements and is free of bugs.a variety of development and tasks can be used to check that the design ha been functionally tested and verified.these include checking that the requirement are correct i.e not in conflict . ,confirming that the design and software code meet the requirements .
verification is done during the development process.validation is done at
the end of the development process.so the functional testing is validation
because it is done at end of the development to verify the product meets
the planned specifications.some types of funtional testing is smoke
tests,sanity tests ,integration test ,acceptance testing and regression
testing.functional testing process do in three main steps 1) creat test(input
values) ,2) excute test cases ,3) compare actual and expected output
