What is the diff betwn Functional nad regression testing
and do u excute same test case or write new one for regression

Answer Posted / saff

as per my knowledge the test cases are written in the
beginning and they r executed once the built is done

so difference between fun and reg is

funtionality testing where we give some input and check
for output =expected one

regression is when we r checking the features of appln if
u find bug ,appln/module/system it is given for
rectification and rectified appln is givne back for
testing at this time ,after competing the testing of the
feature which is fixed, we have to check for the whole
aplln for verifying that whick are already working are
still working or not
so for this we have already wrote test cases which are also
funtional testing test cases only

so untill and unless there is any change in the requirement
we dont have to change our test cases

but if the regression testing is not overall coverage of
appln then we need to write different test cases ,
