Regression Testing

Regression Testing: Regression testing is a critical phase in software development, designed to ensure that recent code changes have not adversely affected the existing functionality of the application. This type of testing involves re-running previously completed tests to confirm that the application still performs as expected after updates or enhancements. By systematically testing various parts of the application, regression testing helps identify any unintended side effects introduced by new changes, thereby maintaining the overall integrity and quality of the software. The process of regression testing can be both manual and automated, depending on the complexity and scale of the software. Automated regression tests are particularly valuable for large applications with frequent updates, as they save time and reduce human error by quickly executing a suite of tests. Effective regression testing not only ensures the reliability of new features but also helps in preserving the user experience and operational stability of the software product.
