If the developer won't accept our sent bug, then we show it 
to our team leader or we can show it to our superior 
person. so he/she will go and discuss with developer or 
else they will conduct one meeting on that.

correct me if i'm wrong:)

Sometimes bug not reproducible in Dev Environment
at that situation dev doesn't accept
we will give him screen shots
If still debate occurs
we raise the issue in bug traige meeting

we just attach a screenshot...which act as a proof and we r 
on the saFER SIDE..

jyothsna is correct if the team lead or project manager 
doesnot accept with that bug we can directly intimate to 
the client that so & so was happening

We have put that issue in Release notes

In this type of situations we have to reproduce the defect 
and capture the snapshots of  that defect and send it  to 
the cocerned developer.some times due changes in the 
development and testing environments also this type of 
problems arises

first i will inform team leader.Then after team leader and
deleloper discussed 


or)snapshot send to developer

If the developer considers the bug as low level or does not 
accept it as a bug, thus pushing it into Not Accepted/Won’t 
fix state. Such bugs will be assigned to the project 
manager who will decide if the bug needs a fix. If it 
needs, then assigns it back to the developer, and if it 
doesn’t, then assigns it back to the tester who will have 
to close the bug.

I will try to reproduce that bug and send the reproduction 
details to respective developer.If still he/she is not 
accepting the bug then I will discuss the issue with my 
lead .Further my lead will decide what to do in this case.
(May be my lead will arrange meeting or communicate with 
developer).

Always report bugs properly with exact steps to reproduce, 
occurrence, severity, screen shots, logs etc. Report the 
bugs in the Defect tracking system. Convince the developer 
about the risk and the priority. If he still does not 
accept the bug - don’t release the product until the bug is 
acknowledged by the Team lead. And make sure to note them 
in the Release notes.
