Q. What do you understand by black box testing?

Black Box Testing:-Black Box Testing is as well called behavioural testing focuses on the functional requirements of the software. It allows the software engineer to derive sets of input conditions that will fully exercise all functional requirements for a program. It is a complementary approach that is probable to uncover a different class of errors than white box testing.

Black Box Testing attempts to discover errors in the following categories:-

1) Incorrect or else missing functions.

2) Interface errors.

3) Errors in data structures or else external database access.

4) Behaviour or else performance errors.

5) Initialization as well as termination errors.

Black Box Testing be likely to be applied during later stages of testing because black box testing purposely disregards control structures attention is focused on the information domain.
