In the context of database testing, what is regression testing, and why is it considered a best practice?
- Testing changes to ensure existing functionality is not affected
- Testing data integrity

Regression testing involves retesting the functionality of the database to ensure that changes or enhancements do not negatively impact existing features or functionalities. It is considered a best practice because it helps in identifying any unintended side effects of modifications or updates to the database schema, queries, or stored procedures. By conducting regression testing, teams can mitigate the risk of introducing defects or regressions into the system, thereby ensuring the stability and reliability of the database application.
