Detailed explanation-1: -A black box refers to a system whose behavior has to be observed entirely by inputs and outputs. Even if the internal structure of the application under examination can be understood, the tester chooses to ignore it. Black box is a software testing style that can describe various test methodologies.
Detailed explanation-2: -Black box testing is based on the requirements and checks the system to validate against predefined requirements.
Detailed explanation-3: -Black-box testing is a method of software testing that examines the functionality of an application without peering into its internal structures or workings. This method of test can be applied virtually to every level of software testing: unit, integration, system and acceptance.
Detailed explanation-4: -Black-box testing, also called functional testing, relies on the input/output behavior of the system. In particular, the system is subjected to external inputs, so that the corresponding outputs are used to verify the conformance of the system to the specified behavior, with no assumptions of what happens in between.
