What does black box testing evaluate?

Black box testing evaluates the functionality of an application without examining its internal workings. The primary focus of this testing method is on the inputs and outputs of the software rather than its internal processes or code structure. Testers interact with the software by providing inputs and observing the outputs, thus assessing how well the application meets its specified requirements. This approach allows for the evaluation of user experience and application behavior, making it crucial in ensuring that the software functions correctly from an end-user perspective.

This method is beneficial for identifying discrepancies between what the software is expected to do and its actual behavior while remaining agnostic to how those results are achieved within the system’s architecture. It allows testers to identify issues based solely on functionality and ensures that the application delivers value to its users without needing detailed knowledge of the underlying code or hardware specifics.
