What is black box testing?

Black box testing is a software testing method that focuses on the functionality of the software without considering its internal structure or code. Testers examine how the software behaves based on specified requirements and specifications to uncover errors or bugs.

During black box testing, testers operate the software as end-users, verifying input and output without knowledge of the system's internal workings. This approach confirms the software's correctness and completeness from a user's perspective.

Black box testing enables testers to validate the software against defined requirements, promoting independent testing without requiring access to internal code. In contrast, white box testing evaluates the system's internal logic, including code structure and paths.

This testing method is most beneficial in the later stages of software development when system functionalities are stable. It ensures that the software aligns with specified requirements and functions accurately for end-users, enhancing overall software quality.
