Functional Testing, also referred to as System Testing of software is the practice of testing the completed software to confirm that it meets the requirements defined for the software. A functional test is typically a test of user interactions, but can also involve communication with external systems. We contrast functional testing with unit testing. We also show how functional testing provides different benefits than unit testing.

Foundation Series: Unit Testing of Software
Testing software is more than just manually banging around (also called monkey testing) and trying to break different parts of the software application. Unit testing is testing a subset of the functionality of a piece of software. A unit test is different from a system test in that it provides information only about a particular subset of the software. In our previous Foundation series post on black box and white box testing, we used the inspections that come bundled with an oil change as examples of unit tests.
