What is the difference between Re-test and Regression Testing?
Re- test - Retesting means we testing only the certain part of an application again and not considering how it will effect in the other part or in the whole application.
Regression Testing - Testing the application after a change in a module or part of the application for testing that is the code change will affect rest of the application.

Re-Test
You have tested an application or a product by executing a test case. The end result deviates from the expected result and is notified as a defect. Developer fixes the defect. The tester executes the same test case that had originally identified the defect to ensure that the defect is rectified.
Regression Test
Developer fixes the defect. Tester re-test the application to ensure that the defect is rectified. He also identifies a set of test cases whose test scenario sorrounds the defect to ensure that the functionality of the application remains stable even after addressing the defect.
On the other hand, if a particular functionality had undergone a minor / major modifications, the tester tests the application to identify defects in the changed functionality followed by the execution of certain set of test cases sorrounding the same functionality to ensure that the application is stable.
It is really very good information.
Thank you so much
If some other information you have then please mail me or comment on this site
Thank you
If you develop your tests before you write the programs, then you will know when coding is done, because the tests all pass. Then if you ever change anything, you run the same tests (and additional ones, as mentioned to test any new functionality), all of them, and if it passes, stop coding.
Regression testing:- We all know that development Life Cycle is subjected to continuous changes as per the req..of user.suppose if there is a change in the existing system which has already been tested. it is essential that one has to make sure that this new changes made to the existing system do not affect the existing functionality. foe ensuring this regression testing is done.
Thanks & Regards,

i was asked this question in interview ....
"is regression testing done only after a change or modification is done in the program,is it not done when a bug is found and fixed?"
....i was confused and said it is done in both cases
...what is the correct answer?
Regression testing:- We all know that development Life Cycle is subjected to continuous changes as per the req..of user.suppose if there is a change in the existing system which has already been tested.
I will give simple example where we have 2 modules i.e. Module A and Module B.suppose I have made changes in Module A
Retesting : Testing Module A only
Regression Testing : Testing Module A and Module B.
yes, it is done in both cases..
Regression testing- we re-execute the test cases on the following criteria-
1. T.C which is dependent on the bug fix or enhancement
2. T.C for f(x) which has shown high probability of failure in past.
3. T.C of a f(x) important for the end user.

retesting: retesting the failed testcases after fixing the bugs by the developer...
regrussion testing: testing whether those changes impact rest of the application or not
may i knw what is test bed..??
track matrix?
colud you give me perfect anwer for this..??
This is very nice and informative post
Thanks for the post on this mostly used topic. In my opinion:
Regression Testing is the execution of all or a select set of test cases which have passed on the previous build or release of the application under test in order to
validate that the original features and functions are still working as they were previously. These tests normally will not have already been executed against the
current build or release as normally only the new features and functions are tested prior to regression testing.
Retesting is the execution of one or a set of test cases which previously failed due to a suspected defect in the software which now is documented as being remedied.

Retesing means testing only those bugs which are fixed to make sure that they r really fixed or not
Regression testing means testing the unchanged features to make sure that the application is not changed because of the modifications done to the previous build...
Some will call retesting as unit regression testing...
