Regression testing: Here regression testing conduct while you are executing test cases or executing automation scripts you found any bug then that bug will correct by the developers after that we execute another time only that test cases and surrounding test cases. Why because that It ensures the previously identify the bugs have been fix. Old bug fixes are not broken else where. No new bugs are not introduced due to code modifications or edition of new code for enhancements. We execute all the test cases against the released build that called regression testing. Retesting: When a bug is first found by a s/w tester it�s logged and assigned to a programmer to be fixed. Once the programmer fixes the code he assigns it back to the tester. Tester performs a retest to conform that bug is really fixed or not.

Hi! The answer is retesting involves the check for the functionality of the previous and the present build is stable or not, incase of Regression testing is checking for the newly added functionality causing any errors in terms of functionality and the common functionality should be stable in the latest and the previous versions

Regression Testing is always Re Testing but Re Testing is sometime Regression Testing. If we are new version of application comes at that time we do Regression Testing.

testing of an application which is already tested to find is there any uncover bugs or not is called retesting. And testing of an application after the bug fixings or enhancements made to the application causing any errors in terms of functionality is known as Regression testing.

Tester should check the application if any errors occurs in your appliaction given to the developement teams, developer rectifies those bugs and again given to the tester. Tester again check the functionality of the application. This is regression testing. Retesting means if any additional features is added in your application on the basis of client requirements, tester check those functionality is retesting.

Hello! The answer is Retesting is the testing done again from the starting to check the stability of the software that wheather the functionalities are still existing or not while Regression testing is the testing done after the change is being made either after the fixation of Bug or by addition of new functionality to check wheather the change has no ill effect on the other part(surrounding Area where change is made) of the software.

retesting when we raise the bug and when the bug is fixed we are going test the bug raised by us is fixed and the problem is solved is called retesting regression when any change in the module or when when bug raised is fixed and we will check that whether the changes may not affect the modules which were previously correctly working

Retesting is to check the functionality with the multiple set of inputs. Regression testing is to test the application after modification are made(bug fixes). these test r done to know the function is stable or not

Retesting is basically done to test the functionality of the build whenever the new functionality is added in it. This include the re- execution of the previous test cases of the build plus the execution of the new test cases of added functionality. Whereas Regression testing is done to find out the impact(+ve or -ve if any) of changed/ added functionality over the new build formed.

retesting of a software system that has been modified to ensure that any bugs have been fixed and that no other previously working functions have failed as a result of the reparations and that newly added features have not created problems with previous versions of the software. Regration testing is based on continuously check the application as n when any new functionalities are added to ensure the system will meet its objective.

Retesting Testing : re-execution of test cases on same application build with different inputs or test data. This is done to make sure that the previous bug is resolved. We do retesting for only the changed Scenario Regression Testing : re-execution of selected test cases on modified build to ensure bug fix work completeness and correctness. We do all the test procedures once u make any new change or add a new functionality

Retesting is nothing but The reexecution of the test cases on the same build where as regression testing is nothing but suppose when a program is enhanced , testing is often done only on the new features , however adding source code to the program introduces errors in other routines and many of the old and stable functions must be retested along with the new ones.

Regression testing is execution of same test cases in subsequent build. For e.g. Login screen - In previous version, there was UID,password, OK & cancel button. After testing there were 100 cases. After testing new version, there added 25 more test cases. so total test cases are 125. So we just have to check that Help button is affecting to previous version of login. This is actually called as Regression testing. In Re-testing, tester can tell programmer for re-testing , he felt that there is still bug whatever fixed bug by that programmer. So that 25 bugs are called type of Re-testing.
