Which of the following would best describe the difference between white-box testing and black-box testing?

A.
White-box testing is performed by an independent programmer team.

B.
Black-box testing uses the bottom-up approach.

C.
White-box testing examines the program internal logical structure.

D.
Black-box testing involves the business units

Explanation:
White box software testing gives the tester access to program source code, data structures, variables, etc.
White box testing gives the tester access to the internal logical structure of the program, while black box testing
gives the tester no internal details: The software is treated as a black box that receives inputs.
Incorrect Answers:A: White-box testing can be performed by any programmer who has access the source code.
B: Black-box testing just hides the internal details of the program. Black-box testing does not use either a
bottom-up, or top down approach.
D: Black-box testing is blind to business units, as it has not access to any internal details of the program.
