The "white box testing" methodology enforces what kind of restriction?


A. The internal operation of a system is completely known to the tester.
B. Only the external operation of a system is accessible to the tester.
C. Only the internal operation of a system is known to the tester.
D. The internal operation of a system is only partly accessible to the tester.

Correct Answer: A

Explanation:

White-box testing (also known as clear box testing, glass box testing, transparent box testing, and structural testing) is a method of testing software that tests internal structures or workings of an application, as opposed to its functionality (i.e. black-box testing). In white-box testing an internal perspective of the system, as well as programming skills, are used to design test cases.
