Regression and Re-testing
Difference between Regression and Re-testing
AS now onwards we always link with testing topic. So i am also connecting you to the same topic.
Lets start I am sure that every tester pass through this condition that we confuse between Re-testing and Regression testing.
Re-Testing is mainly done after fixing a bug.to ensure that the is bug fixed/removed.
or Re-Testing is done to check same test case for multiple no. of data.
Same time Regression testing is start after having a change in the functionality of the application for which we have a test case or scripts.To check that is there any effect on our scripts response time and all after deployment of changes in code and functionality.
Now we are taking example of both the testing:-
1.Re-Testing:-

Regression Testing
|
|
Re-testing is done to
check that the test case which is failing in last execution passed now after
fixing the errors.
|
Regression testing is
somehow similar to Re-Testing. But the difference is that, it is done to
check that, Is there any effect after changing some functionality/code in the
application.
|
|
Re-testing is carried
out based on the defect fixed.
|
Regression testing is
planned after the change in back end code.
|
|
In Re-testing, We
mainly re test the test cases which are failing in the last execution.
|
In Regression
testing,We include the test cases which are passing in the last execution.
|
|
We cannot automate the
test cases for Re-testing.
|
Automation is used for
regression testing.
|
|
Defect verification is
comes under Re-testing.
|
Defect verification is
not comes under Regression testing.
|
|
Priority of Re-testing
over Regression testing is higher, so it is carried out before regression
testing.
|
Based on the
availability of resources the Regression testing can be carried out parallel
with Re-testing.
|
Now we are taking example of both the testing:-
1.Re-Testing:-
- we have a image uploading field which supports only certain image formats say JPEG, PNG etc. Suppose one of the image formats failed (say JPEG) and the developer fixed it. Testing the functionality, after fixing this bug is re-testing.
2.Regression Testing:-
- Testing and ensuring whether above new change has not altered the working of other fields on that page is regression testing.
