Defect Life Cycle

Error: We can’t compile or run a program due to coding mistake in a program. If a developer unable to successfully compile or run a program then they call it as an error

Bugs:If testers find any mismatch in the application/system in testing phase then they call it as Bug.

Defect:After bugs is find when tester send to developer  that bugs is call defect

• Verified: The tester re-tests the bug after it got fixed by the developer. If there is no bug detected in the software, then the bug is fixed and the status assigned is "verified."
• Reopen: If the bug persists even after the developer has fixed the bug, the tester changes the status to "reopened". Once again the bug goes through the life cycle.
• Closed: If the bug is no longer exists then tester assigns the status "Closed." 
• Duplicate: If the defect is repeated twice or the defect corresponds the same concept of the bug, the status is changed to "duplicate."
• Rejected: If the developer feels the defect is not a genuine defect then it changes the defect to "rejected."
• Deferred: If the present bug is not of a prime priority and if it is expected to get fixed in the next release, then status "Deferred" is assigned to such bugs
• Not a bug:If it does not affect the functionality of the application then the status assigned to a bug is "Not a bug".
