Description: Regression test groups are sets of test cases that are executed to ensure that recent changes have not negatively affected existing functionality. These groups are fundamental in the software development process, as they allow for verification that new features, bug fixes, or updates do not introduce failures in previously implemented functionalities. Regression refers to the possibility that a change in the code causes unexpected behavior in parts of the software that were already functioning correctly. Therefore, regression testing is an essential practice in quality assurance, as it helps maintain the stability and reliability of the software over time. These tests can be manual or automated, and their design must be meticulous to cover all critical aspects of the system. Regular execution of regression tests, especially after each development iteration, is crucial for early problem detection and ensuring that the software meets the required quality standards before its release to the market.
