What is a functional test

A functional test is a type of software testing that is performed to verify whether each function of an application is working correctly. It aims to test the overall functionality of the software system, ensuring that it meets the requirements specified in the functional specifications. This type of testing is often done from the user's point of view to ensure that the software behaves as expected and delivers the desired results. Functional tests typically cover various use cases and scenarios to validate the application's features, data manipulation, user interfaces, and integrations with other systems.
