Question { IBM, 22898 }

What is the difference between bottom-up and top-down
integraion?Which is effecive.

Answer

Generally products are developed with Bottom up approach.

Say we have have to deliver one application contains 10
modules. One by one module is develpoed and need to be
tested. but how will you invoke that singe module, you will
be needing Driver to invoke it. As sooner other modules
will finished they will be integrated with it and
similarily you will have complete application.

In top down you will have main module is ready to
accomodate other modules that are getting develpoed
simultaneously.

Correct me if i m wrong

Question { IBM, 18259 }

there are 100 test cases. and u got a bug at 85th test
cases. u reported it to dev and dev fixed that bug. when u
r doing regression testing from whic test case u'll do
tetsing?? will start from 85 th test case are u'll execute
100 test cases??

Answer

As we are in regression testing so we will log bug for it
and continue further testing if it has no severe impact on
the application like show stopper. While verifying the bug
after it got fixed, we will do re execute test cases which
can be effected by fix in new build.

If developer is not agree with your bug then what is your
response?

Answer

If Developer never agrees about the Bug, probably they
provide reason
1. This is running from last long and customer didn't have
any problem with this; so leave it but only if its severity
is very low
2. This is as by design time and acceptable, so leave this
too
3. otherwise He always say that he cannot reproduce the bug
in latest build , means due to some other fixes this issue
also has been fixed. Leave this too.
4. Except all above you can convince him only.
