What is the difference between white and black box testing?..

Answer / log_vivek

Black-box doesn’t explicitly use knowledge of the internal
structure. Black-box test design is usually described as
focusing on testing functional requirements. 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.
