Which of the following is a benefit of Black Box Testing?

1. Deep understanding of code

2. Verification from a user's perspective

3. Complete debugging of software

4. Faster development times

The correct answer is: Verification from a user's perspective

Black Box Testing primarily focuses on examining the functionality of an application without any knowledge of its internal structures or workings. The main advantage is that it allows for verification from a user's perspective. Testers interact with the software as an end-user would, validating whether the software meets the user requirements and behaves as expected under various conditions. This type of testing is crucial for ensuring user satisfaction and finding issues that could affect the user experience, which may not be evident from the code alone. In contrast, having a deep understanding of code is more aligned with White Box Testing, which examines the internal logic and structure of the code. Black Box Testing does not aim to debug the software comprehensively; instead, it identifies discrepancies between the actual outputs and the expected outputs. Lastly, while Black Box Testing may streamline some aspects of the testing process, it does not inherently lead to faster development times, as thorough testing requires careful planning and execution, independent of the testing method employed.
