To fix the reported bug ,modifications in the code will be 
done,Due to the modifications in code they may create some 
new bugs.For that we need to do regression testing

Regression testing is testing the modified build,whether it
is effecting the application or due to modified build any
new bugs are raised.

Retesting subset of test cases on the modified build in
order to ensure the application and check for the adverse
effects

Testing whether the bug fixing has not lead to other 
defects or bugs in the Software application is what 
Regression Testing means

Retesting of the software with the modifications made due 
to previous found bugs.

HI

   Regression Testing is to 
   
   1. To check the Build After Retest that the corrected
      Build should not cause any impact over the screen
      or Referencial Modules

   2. When the Build added with new features we go 
      for regression test.

Whenever enhancements added to the existing functionality 
then only we go for Regression testing why because new 
changes are whether effecting the old functionality or not.

                       (OR)

it is a type of testing. In which already tested 
fuctionality is once again tested in two scenarios.

1. whenever the defects are identified by the testengineer 
rectified by the developer and released to the testing 
department then the test engineer will once again test the 
defect functionality and the related functionality.

2.  whenever the new changes are incorporated by the 
developer and released to the testing department the 
testengineer will once again test the related old 
functionality in order to ensure that they remain same..

When the bug fixed by developers we have to check that 
application due to bug fixing there will be a probability 
occurring some other bugs else where in the program

Regression Testing : Testing an application after it get
modified in order to check whether there is any effect on
the other parts of the application after the modification.

regression testing:
                   this is conducted by the test 
engineer.to test the modified build .It is modified or not 
that is called regression testing

Regression Testing is Testing the software whether the bug 
fixed is working without affecting previously tested 
functionality. Regression Testing will be done when we got 
modified build
