Regression Testing: Regression testing, also known as generic testing, revolves around re-running functional and non-functional tests. It is especially done to ensure whether previously developed and tested software still performs the same after a change or not. It can be performed either manually or using automated tests.
Re-testing: Re-testing, also known as planned testing, is used for specific bugs after it has been fixed by the developers. Re-testing is performed to check the scenario under the same environmental conditions after detection has been fixed.
Regression vs Retesting:
| Regression | Retesting |
|---|---|
| It is performed to make sure that the changes haven’t affected the unchanged part. | It is performed to make sure that the test cases that were filed in the last execution are passed after the detects are fixed by developers. |
| It is not carried out for specific detect fixes. | It is usually carried out based on defect fixes. |
| It is only the previous version functionality-centric. | It is current or previous version functionality-centric. |
| It can be performed parallel with retesting. | It is needed to perform before regression testing. |
| It does not include the verification of bugs. | It includes the verification of bugs. |
| In this type of testing, test cases can be automated and the testing style is generic. | In this type of testing, test cases cannot be automated and the testing is done in a planned manner. |
| It is only used for passed test cases. | It is only used for failed test cases. |
