Black Box Testing

Black Box Testing is a software testing method where the tester evaluates the functionality of an application without having any knowledge of its internal code structure, implementation details, or internal paths. The primary focus of this testing approach is to validate the input and output of the software to ensure it meets the specified requirements. Testers using this method treat the software as a “black box,” where they cannot see the internal workings but only interact with the software through its user interface or external interfaces.

This approach is beneficial for detecting discrepancies, missing functions, and interface issues. Black Box Testing is commonly used in various levels of testing, including unit, integration, system, and acceptance testing. By mimicking the end-user experience, this method helps ensure that the software functions correctly in real-world scenarios, offering an unbiased assessment of the system’s behavior.
