What is Regression Testing?

Answer Posted / techie

Regression testing as the name suggests is used to test /
check the effect of changes made in the code.

Regression Testing is retesting unchanged segments of
application. It involves rerunning tests that have been
previously executed to ensure that the same results can be
achieved currently as were achieved when the segment was
last tested.

The selective retesting of a software system that has been
modified to ensure that any bugs have been fixed and that
no other previously working functions have failed as a
result of the fixes and that newly added features have not
created problems with previous versions of the software.
