Black box testing focuses on validating software behavior based on inputs and expected outputs, without considering internal implementation details. This makes it effective for identifying functional gaps and incorrect behavior from a user or system perspective.

By applying black box testing, teams can uncover issues related to requirements, integrations, and end-to-end workflows that may not surface during unit or code-level testing. It is commonly used for testing user interfaces, APIs, and interconnected systems.

Including black box testing in a broader testing strategy helps teams ensure that software behaves correctly in real-world scenarios and continues to meet user expectations.
