The term "black box" is used because the actual program being executed is not examined. In computing in general, a black box program is one where the user cannot see the inner workings (perhaps because it is a closed source program) or one which has no side effects and the function of which need not be examined, a routine suitable for re-use.
[5] Spinuzzi notes that in most cases self-regulating black boxes can’t propagate because the opaque internal work is too extempore and ad hoc to work on a broad scale. Black-boxing as an approach has been criticized by scholars such as Langdon Winner for being excessively formulaic in method and too narrow in focus. [6]

On the other hand, black-box testing has been said to be "like a walk in a dark labyrinth without a flashlight." [ 11 ] Because they do not examine the source code, there are situations when a tester writes many test cases to check something that could have been tested by only one test case or leaves some parts of the program untested.
The data, which totals more than a thousand parameters, is swiftly saved electronically into the flight data recorder (FDR), one of the so-called black boxes that aviation safety investigators say ...
