Computer Science - System Analysis and Design - Discussion

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.

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.

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.

Option D is the correct answer.

Option A is correct.
