Software Quality Assurance Practice Exam

What technique is used to ensure that transactions are completed properly?

1. Data validation

2. Business tier testing

3. Code refactoring

4. Launch readiness assessments

The correct answer is: Business tier testing

The technique utilized to ensure that transactions are completed properly is primarily associated with business tier testing. This approach focuses on validating the business logic and workflow of the application, which encompasses how transactions are processed and managed within the business layer of the software. By engaging in thorough testing at this level, teams can ensure that all rules governing transactions are enforced correctly, leading to proper completion and integrity of the operations. Business tier testing involves verifying that the application handles transactions as intended, including verifying that inputs are processed correctly, outputs are accurate, and any associated data manipulations align with business requirements. This type of testing helps identify potential issues in transaction handling before they reach the end-user, thereby increasing the overall reliability of the system. While other options like data validation and launch readiness assessments play important roles in software quality assurance, they do not specifically focus on the transaction completion aspect of the application. Data validation ensures that input data meets certain criteria but does not directly verify transaction processing. Launch readiness assessments evaluate the overall state of the application before deployment but do not focus exclusively on transactions either. Code refactoring relates to improving code structure and readability and does not pertain to the transactional validation process. Therefore, business tier testing is the most relevant technique for ensuring proper transaction completion.
