What is black box texting?

Black box testing" is a method of software testing that examines the functionality of an application without peeking into its internal structures or workings. It is called a "black box" because, to the tester, the test object is a "black box" and its internal structures are unknown. The tester only knows what inputs are given to the system and what outputs are expected, but does not have access to the internal workings of the system. The goal of black box testing is to ensure that the system behaves as expected, regardless of its internal implementation.
