Software Quality Assurance Practice Exam

What is being verified when testing the business tier?

1. The backend data entry and management routines

2. That recovery can be done using current backups

3. That transactions are completed properly

4. That graphics are the correct size and resolution

The correct answer is: That transactions are completed properly

When testing the business tier, the focus is on ensuring that transactions are completed properly. The business tier, often referred to as the business logic layer, is responsible for processing data and managing business rules and workflows. This tier acts as an intermediary between the presentation layer (what the user interacts with) and the data layer (where data is stored and retrieved). Verifying the proper completion of transactions is critical because it ensures that all business processes execute as intended, leading to the correct functioning of the application. This includes validating that all operations—such as calculations, data validations, and state changes—are processed accurately and efficiently according to specification. Testing the business tier encompasses checking various aspects, such as: - Ensuring that data input is correctly processed according to business rules. - Validating that outcomes are as expected after transactions are performed. - Monitoring for errors or exceptions that might occur during transaction processing. The other options relate more to different aspects of software testing. For instance, backend data entry and management routines focus on the operational side of data handling rather than transaction logic. Recovery and backup testing is about data integrity and availability, not necessarily about the logical correctness of business transactions. Testing graphics pertains specifically to the presentation layer, which is unrelated to the business logic
