Non-Regression testing (NRT) is an approach of software testing which verifies if the desired previous functionalities of a software application were not compromised after the introduction of new procedures or functional modifications in a new release. The observation of undesired behaviours generally indicates a software regression, i.e. the new features added to the software introduced software bugs in the functionalities that were working in the right way in its previous version.
