Hi ,

Regression Testing :

After getting confirmation that the bug
is fixed,we would validate if the fixation is giving rise
to any bugs.

Retesting: Re-execution of the same TestCases with
different set of data.

Answer / surii

Regression Testing : In this testing already tested
functionality is once again tested whenever there is a
change i.e. associated with inorder to check whether the
already existed functionality has got affected or not.

Retesting : In this testing already tested functionality is
once again tested with different sets of test data. Before
going to raise any defect it is a tester responsibility to
check whether that defect is a reproduceble or not. So test
engg. must confirm that defect wiht different sets of test data.

Retesting is performed in Regression testing but not vice versa.

Answer / shirish

Retest in done when you are not sure of the result like not
sure if you followed the given steps or just to make sure
the bug has really occurred. Retest is also done when you
want to show the bug appears on you system if the developer
denies it or show the steps to reproduce the bug.
Other condition when retest is done to see if its been fixed,

On the other hand regression is to check the bug is fixed
and no other bug has occurred while fixing that.
