Software Quality Assurance Practice Exam

What must a black-box tester focus on?

1. Knowledge at the source code level

2. How each individual piece of the application works

3. Expected outputs of the program, but not every input

4. What a program is supposed to do and who it is for

The correct answer is: What a program is supposed to do and who it is for

A black-box tester primarily focuses on what the software application is expected to do and the needs of the user it is designed for. This approach emphasizes the functionality of the application based on requirements and specifications, rather than delving into the internal workings or source code of the software. Understanding the intended functionality allows black-box testers to create tests that validate whether the software meets its design specifications and user expectations without needing access to the internal code structure. This perspective is crucial for assessing usability, compliance with business requirements, and overall user satisfaction. Other options delve into areas that are more relevant to white-box testing or software development processes. For instance, knowledge of the source code level or the inner workings of individual components is not pertinent for black-box testing, as the tester does not concern themselves with how the program achieves its outcomes, but rather with what results are delivered from an end-user perspective.
