Software Quality Assurance Practice Exam

Which statement matches the Data validation section of the business layer testing area?

1. Tests to detect errors in knowledge collected from customers

2. Tests to uncover errors in transaction processing, such as credit card processing, e-mailing verifications, and so on

3. Tests whether the application meets documented operational specifications

4. Tests the usability and user interface of the application

The correct answer is: Tests to detect errors in knowledge collected from customers

The statement that aligns with the Data validation section of the business layer testing area focuses on ensuring that the information processed by the application is accurate and meets specific criteria. Data validation tests are designed to confirm that the data collected—from customers or other sources—does not contain any errors or inconsistencies. This can include validating input fields, checking for data types, ensuring required fields are filled, and that the data adheres to defined rules or formats. This is critical in maintaining the integrity of the data that drives the application's functionality and ensuring that users can rely on accurate information. The emphasis here is on the correctness and appropriateness of the data rather than the functionality of transactions, operational specifications, or the user interface. Such validation is essential for preventing issues further down the process, such as database errors or incorrect processing results, which can lead to significant problems for users and the business.
