BLACK BOX TESTING, also known as Behavioral Testing, is a software testing method in which the internal structure/design/implementation of the item being tested is not known to the tester. These tests can be functional or non-functional, though usually functional.

This method is named so because the software program, in the eyes of the tester, is like a black box; inside which one cannot see.

This method attempts to find errors in the following categories:

> Incorrect or missing functions.
> Interface errors.
> Errors in data structures or external database access.
> Behavior or performance errors.
> Initialization and termination errors.

Option D is the correct answer.

Option A is correct.

According to me option B is correct one because in black box testing we made the assumption about stability in concern with input and output of the system.

I think option A is correct because in the black box testing we give inputs and outputs but we are not concerned with the processing or how the input is converted into output.
