New: As part of testing when you find an issue, you perform all the relevant checks, like whether it was occurring in the earlier release, if so then you will reopen the bug, if not then you will create new defect and the status of that defect will be "NEW"
Open: Once you open a new bug, it will be revised by Development/Project Manager and then he will assign it to the developer, then the status of the bug will be changed from NEW to OPEN
When a tester found a bug in a software during testing and the bug is verified by the T.L. then it is called the "New" state of a bug. When the Testing Lead sent the bug to Development Lead for modification and it is verified by the D.L. it is called the "Assigned" state of a bug. The bug is then transferred to development team to fix it. The developer open the bug it is called the "Open" state of a bug.
When a tester finds a bug he makes the status New and shows this to team lead who decides whether it is really bug and then changes the status to open and sends this to developer to fix the bug.
New : If a tested found an issue while doing testing then he logged the issue in Defect tracking system and reported the same to his lead/manager.
Open: Lead/manager has to be review the same issue if he feels it's really a bug then he changed the status to Open and reported same to development lead or else changed the status to Closed.
New: As part of testing when you find an issue you perform all the relevant checks like whether it was occurring in the earlier release if so then you will reopen the bug if not then you will create new defect and the status of that defect will be NEW
Open: Once you open a new bug it will be revised by Development/Project Manager and then he will assign it to the developer then the status of the bug will be changed from NEW to OPEN
if a tester is testing an application and finds a bug then it is called a New bug and then it is sent to development team and if the development team says that it is a really bug then it comes under the Open Stage.
There is NO OPEN status it is just a Terminology which is frequently used. When Tester Looged an Issue i.e BUG which is in NEW status and that particular Bug was not resolved untill that Particular Project's release time will say that there is still some OPEN defects for this release it is resolved fine otherwise will DEFER that Defect based on Business people Comments.
****In QC9.2 also there is No specific status like OPEN .
In QC 9.2 there is a specific status called Open that actually depends on the customization of the defect module in QC by your project admin. He may define the defect workflow as per your company process where open bug may not be there.
New Bug can be defined as the bug which was found freshly and had been logged with status as New.This is the Intail state of a Bug
Open bug can be defined as in such way that a bug which was in closed or terminated state can be set to status open and can be assigned back to a developer for solving. This is one of the example
Open bug may also be treated as a state next to New Bug.that means the bug had been identified as a valid one and had been assigned to person in active state.
Difference between New bug and Open Bug is nothing but firstly the tester is going the assign the status as New after that when ever the developer opens that defect and he will changes to status as open and then he is going tochange it into closed.
So the "New" status for a bug is given by Tester and "Open" status is changed by the developer when he is inthe process of fixing that defect..
