Regression test will be done when we got modified build

there we execute test cases to determine whether defects
closed or not?

or checking 2 ensure that resolved bug has made any impact
on the remaining part of code

Answer / rajasundar

Testing the product accross the builds is called the
Regression Testing.

The process is :

The QE is given with build 1 and during testing he found
some of the areas are not working and those are identified
as bugs and he registered the bugs against that build.
Accepting that the dev. team address/fix all or some of
those bugs and they will release a new build for testing.

Now from build2 the method of testing is bit different..
1. Verifying the fixes (TBV - To Be Verified).
2. Identify the cases affected by the fix.
3. Executing some % of Legacy cases (Cases perfectly work
in Previous build).
3. Test Cases developed and ready to execute for new
functionality area.

The above process continues till Release Candidates.

Note : The bugs raised in the previous build should be
converted to Test cases for the next build.

Regression Testing-"Testing to ensure that introduction of
new functionality has not affected existing functionality"

Answer / psandhu

Regression Testing is as discussed in above answer is done
after the first build release, and in regression testing we
test if the bugs that exited in the Build are actually fixed
or not, we also apply testcases for new requirements (if
any) to check if the system is working fine.

Answer / parmod

Whenever tester gets the next fixed build:
1)He tests for the Fixed Bugs.
2)Test the whole application to check whether these fixes,
have not introduced new bugs.
3)If there are some update in the application, then test
cases need to be updated , and executed the same.

All of the above steps used, while doing regression testing.

Answer / archana

Hi Pramod,
i Agree with your answer. but a small confusion while
doing regression we do execute all the test cases? or only
few test cases which are related to particular bug??

Answer / neelavathy.r

Regression testing is nothing but, retesting the modified
build to estimate the bug fix work and the occurances of
side effects in the build.

First we are conducting test on failed and then passed
tests on modified build and then on related tests.

Answer / psandhu

Regarding the regression testing procedure, it is same as
testing, we just re-run all those test that were previously
run, but this time we make sure that the test cases match
the new chnages, or new requirements that were not there in
the system.

Answer / pradeep.b

regression testing:when ever the bug is fixed from
developement team we can verify whether the bug is fixed or
not and their related functionality is also working fine or
not.

Answer / neelavathy

The regression testing is conducted on modified build, as
soon as we get the modified build from the development team
we conduct testing on previously failed test and then passed
tests and then related tests. If any mismatches occur then
we are submitting the bug report to the lead.
