What is Retesting & Regression Testing? When do we use
retesting & regression testing(i.e In what situation)?
Please clear me.

Answer Posted / priyan

when a developer fix the bug and send the modified build to
a tester, first tester do Re-testing on that module or
application. Re-testing means, testing the module whether
the bug is fixed or not with multiple sets of data.. then

Regression testing : when the tester come's to conformation
that the big is fixed, then he starts Regression testing on
that modified build. in this testing, the tester test's or
checks whether the modified build is showing any impact on
other application or not.. means whether new application or
functionality is effecting other application or not.the
tester checks after fixation of bug,we got any side effects
in application or not...

why because , during the bug fixing some parts of coding may
be changed or functionality mat be manipulated.. in this
case the old test cases will up-dated or completely
re-written according to new feauter of application where bug
fixed area.....

if any mistake pls correct me .. tank u every body
