Answer / sudhakar8

Black Box testing: The software tester only knows what the
system is supposed to do, he does not know how it works
internally. He has to test on the basis of expected
outputs.
E.g.: System Testing

White Box testing: The software tester has access to the
program/ code and examine it for errors. Also called Clear
Box testing or Structural Testing
E.g.: Unit Testing

Answer / mfsi_krushnas

Black-box and white-box are test design methods. Black-box
test design
treats the system as a "black-box", so it doesn't explicitly use
knowledge of the internal structure. Black-box test design
is usually
described as focusing on testing functional requirements.
Synonyms for
black-box include: behavioral, functional, opaque-box, and
closed-box. White-box test design allows one to peek inside
the "box",
and it focuses specifically on using internal knowledge of
the software
to guide the selection of test data. Synonyms for white-box
include:
structural, glass-box and clear-box.
