How does automated regression testing benefit software development?

Automated regression testing plays a crucial role in software development by ensuring that any new code changes integrate seamlessly with the existing codebase without causing unintended side effects. This process involves running predefined test cases to verify that the functionality that worked previously still functions correctly after new updates or modifications are made. By doing so, automated regression testing helps to maintain the stability and reliability of the software, thereby reducing the risk of bugs being introduced when enhancements or fixes are implemented.

This approach also promotes rapid development cycles, as developers can confidently make changes, knowing that the automated tests will catch any regressions. This not only saves time in the long run but also fosters a culture of quality assurance within development teams.

While the elimination of manual testing, a focus solely on user interface testing, and a reduction in code size may involve aspects of software testing or development, they do not encapsulate the primary objective of regression testing, which is to safeguard existing functionality amid ongoing development.
