What is Black Box Testing?

Black box testing is a software testing method where the internal structure, design, or implementation of the item being tested is not known to the tester. Instead, the tester focuses on providing inputs and observing outputs, without knowing how the system processes the inputs to produce the outputs. This approach is analogous to treating the software as a “black box” whose internal workings are hidden from view. The goal of black box testing is to evaluate the functionality and behavior of the software, identifying any discrepancies between expected and actual results. It is particularly useful for validating requirements, finding bugs, and assessing overall system quality without delving into the complexities of the code.
