Software Quality Assurance Practice Exam

What is the primary purpose of testing in the business layer?

1. To verify graphics resolution

2. To ensure data is collected correctly

3. To validate user interface design

4. To assess load capacity

The correct answer is: To ensure data is collected correctly

The primary purpose of testing in the business layer focuses on ensuring that data is collected correctly. This layer is responsible for the business logic and rules, which are critical in manipulating and processing data to align with the organization's requirements. Testing in this layer involves validating that the data flows correctly through the system, that calculations and business rules are applied accurately, and that the outputs meet the expected outcomes based on the inputs. Testing at this level is vital for confirming that the underlying business processes work as intended before they are exposed to user interfaces or other systems. It ensures that the functionality is not only present but operates accurately, supporting the overall integrity and reliability of the application. While the other options touch on important areas of testing, they focus on different layers or aspects. For instance, verifying graphics resolution pertains to the presentation layer, validating user interface design is associated with usability and the user experience, and assessing load capacity relates to performance testing rather than business logic validation. Therefore, ensuring data collection accuracy in the business layer is key to maintaining effective software functionality and ultimately fostering trust in the application’s outputs.
