Functional testing is a type of black-box testing that is part of the quality assurance (QA) process and bases its test cases on the requirements of the software component being tested. Internal software structure is rarely taken into account when testing functions; instead, input is provided and the results are examined (unlike white-box testing). Functional testing is done to determine whether a system or component complies with the required functional specifications. Functional testing typically outlines the system's functionality. 

Before your software is published to consumers, functional testing may help guarantee that it is free of errors and complies with all necessary requirements. Functional testing approaches can help you uncover and correct bugs before they have a severe negative impact on your company's operations or its clients.
