Difference Between Regression Testing and Re-testing in SAP Testing

Regression testing and re-testing are two essential testing processes in SAP Testing, each serving distinct purposes.

Regression Testing

Regression testing involves re-executing test cases on the entire application to ensure that new code changes have not affected the existing functionality. It aims to uncover any unintended side effects of new developments and ensures that the software still performs as expected after modifications.

Re-testing

Re-testing, on the other hand, focuses on validating that specific defects identified in previous testing cycles have been successfully fixed. It involves running test cases related to the reported issues to confirm that the reported bug has been resolved.

Key Differences

• Regression testing validates overall system functionality after changes, while re-testing verifies specific bug fixes.
• Regression testing is more comprehensive and involves running a full suite of test cases, whereas re-testing is targeted at specific areas of concern.
• Regression testing helps detect unintended consequences of code changes, while re-testing ensures that reported issues have been resolved satisfactorily.

Both regression testing and re-testing are crucial components of SAP Testing, and understanding their differences is essential for effective quality assurance processes.
