Automation frameworks facilitate consistent test execution, which is crucial for reliable and accurate results. Consistency ensures that tests are performed uniformly, reducing the likelihood of errors and inconsistencies.

Test automation frameworks offer a systematic methodology for designing and executing database tests. These tests encompass various aspects such as validating data integrity, testing database performance, and ensuring compliance with business rules.

In this scenario, the vulnerability identified is Insecure Direct Object References (IDOR). It occurs when an application exposes internal implementation objects to users without proper authorization. To address this, the application should implement proper access controls and validate user permissions before granting access to sensitive features or data.

SQL query testing aims to find logical errors such as incorrect join conditions or incorrect data filtering, which may not result in syntax or runtime errors.

The DELETE statement is commonly exploited in SQL injection attacks because it allows attackers to delete data from the database, potentially causing data loss or manipulation.

Automation frameworks for database testing need to support various database instances to cater to different database management systems. This flexibility ensures compatibility and effectiveness across diverse environments.

Integration tests are typically run as part of the CI/CD pipeline for database changes. These tests ensure that individual database components work together correctly, and integrations with other systems or modules are functioning as expected. They help catch issues early in the development process and ensure the overall stability and reliability of the database changes.

ETL (Extract, Transform, Load) testing ensures the successful migration and transformation of data across various systems, databases, or applications. Therefore, the correct option is "Systems."

The principle of "least privilege" dictates that users should be granted only the minimum level of access or permissions necessary to perform their tasks, reducing the risk of unauthorized access or misuse of sensitive data. This helps enhance security by limiting potential vulnerabilities.

The correct option is "ROLLBACK." When starting a transaction with BEGIN TRANSACTION, it must be followed by a corresponding ROLLBACK statement to undo the changes made within the transaction if necessary.
