What is Regression Testing?
Regression testing is a method of software application testing that entails rerunning or retesting a system or application after changes have been made to make sure that the functionality is still working as planned and that any new changes have not resulted in any unexpected consequences or bugs.
The prime aim of considering Regression testing is to identify flaws or bugs that may have entered into the software while changing or upgrading the codes. It aids in ensuring that the software’s modifications did not significantly impact its current functionality or cause any problems.
Regression testing usually involves executing a set of test cases that cover both the system’s affected areas and are potentially likely to be impacted by the modifications made in coding. To identify any changes or problems, the outcomes of these tests are then compared to those of earlier tests.
As it helps to assure the quality and stability of the product, regression testing is a crucial step in the software development process. Since it is usually done at different points in the development cycle, so hiring a software developer in India is a worthy decision to ensure peace of mind that your product’s quality is in safe hands.
