What is the primary goal of executing regression tests?

The primary goal of executing regression tests is to ensure that new code changes do not introduce new defects into existing functionality. When modifications are made to the software, whether they are bug fixes, enhancements, or new features, there is a risk that these changes could inadvertently affect the already working parts of the application. Regression testing involves re-running previously completed tests to verify that previously developed and tested software still performs after a change. This helps maintain the integrity of existing features while allowing for the introduction of new ones.

While assessing usability, evaluating system performance, and confirming feature correctness are important testing activities, they do not specifically address the concern of ensuring that new code does not disrupt previously working functionality. These activities might be part of a broader testing strategy, but they do not target the unique need that regression testing fulfills in verifying the stability and reliability of the software as it evolves.
