Regression testing

[saiseetha]

Hi,
I've faced this interview question.Can anyone please give the answer.
Did you perform regression testing for the whole application?
How did you perform?
Thanks
Saiseetha.

Regression testing is done on the whole application.
Usually Regression testing done whenever a new build or feature of the application is developed. This to ensure that the new feature should work fine as well the old features are not affected by the new feature.

Generally Automation testing used for Regression testing since Repeating same tests whenever new build comes, manually is really hectic job.

Regression testing:

Once defects are found throughout the testing process those are documented in the test log and sent it back to the development team with corresponding testcase Id and reference id. Development team checks whether they are valid bugs or not and fixes it accordingly and sent it back to the Testing team for confirmation testing or so called re-testing.
But due to this fixation of code it might cause some adverse affect to the product under consideration.It might happen all the other scenarios those passed earlier due to this change been affected.So as a whole all the things are working fine or not we take care of with regression testing.

Regression testing is the re-execution of some subset of tests that have already been conducted to ensure that changes have not propagated unintended side affects. Regression testing is also done when there is a change in the Testing Environment..as per my experience test management tools (getzephyr dot com) will help to organize the whole process and make the work easy.

Hi
Regression Testing is done over whole product(or application) every time when some bug has been fixed by developer or some test environment or some test condition has been changed.It is also done when some build or release has been made.
Regression testing is the process of measuring the effect(or impact) of fixing bug in one module to all other module.

From my experience, we will do testing on whole application but we will not test with every single unit of feature. This is the cost related. So, my practice is selecting the test case that can represent each main feature and using it as regression test suite.

Hi

After any bug is fixed or after any new functionality is being added to any application, regression testing is done.
Regression testing is done to make sure that after fixing/modifying the application, other remaining modules in that application are affected or not due to the module fixed/changed/added.

Hi All
Regression Testing:
If some modification is done to the code,we need to check the previously designed code is working as previous or not.This testing technique is called as Regression testing.

Thanks

Hi saiseetha,

Regression testing is a testing process which tests the side-effects of a updated module on the side-by modules.
So, whenever a debugged module or new module added to the application we have to do regression testing but only for the neighbor modules of that debugged or new modules.

Thanks and regards
