When is a defect a duplicate?
We have a minor debate going on in our QA team, and I'm curious what others think. Two test cases fail with similar behavior, but different execution paths. Two defects are opened. Development team says the root cause of both defects is the same, thus one is a duplicate of the other. The debate is whether duplicate defects are based off of application behavior or root cause.
In our organization, there's one defect (2nd one opened is a duplicate), but there are two test cases which fail.
