The functional testing process focuses solely on what the system does, not how, why, or even how well. The internal structure of the application is rarely considered during functional testing. Instead, it checks the program function against all available documentation prepared prior to development. The system’s compliance with these and other requirements are the primary focus of functional testing.
For each of the many functional testing types utilized, the tester identifies the expected behavior, creates data to use for the type of test being performed, determines the appropriate output, executes the tests, and then compares the actual and expected outputs based on the functional, business, or design requirements and specifications. Testers set out to verify each specific action and code function using manual or automated tests, or most often a mixture of both. User commands, data updates, searches, and UI functionality are examples of functions that are tested. Defects found during functional testing are very often related to the user interface or inter-process communication.
