Black box testing

Black box testing is a type of testing that is focused on evaluating the functionality of a software application or system, without knowledge of its internal implementation or structure. Black box testing is based on the external specifications of the system, such as its input, output, and behavior, and does not require any knowledge of the internal workings of the system.

Black box testing can be used to test a variety of aspects of a software application or system, including its functional requirements, compatibility, performance, and security. It can also be used to test the system’s behavior in different environments and scenarios.

Black box testing is often contrasted with white box testing, which is a type of testing that is based on knowledge of the internal implementation and structure of the system. Black box testing is a useful technique for testing the overall functionality and behavior of a system, while white box testing is more focused on individual components and code.
