developer says it is not defect.then as a test engineer
what u will do?

Answer

When a developer say it is not defect. Then, ask the
developer to give a complete and proper justification note
to that effect. Then, if found that developer has mis-
understood the requirements/reproduction steps given in bug
report then convice him about his mistake.
In short if tester is sure that it is really a defect then
challenge the developer in a healthy manner.
