Q: What is bug life cycle?
A: It is a process from where an issue is reported to closed status. Means, suppose an issue is reported from QA side to developer then developer make their status like resolved, not a bug (due to technical reason), referred to further process (low priority) then QA team review the resolved status issue & if get it is resolved then have the closed status.
For bug life cycle get an example: Like there is “contact form” and “QA/QA Team” reported bug to “developer” like “value of name field” is not passed with “email notification to admin/site owner” then “developer” reviewed the code again and after fixing this issue reported back to “QA or Team” then further “QA” will verify and get now “value of name field” is being passed with “email notification to admin” then “bug life cycle” is followed.
But still get some other related issue due to wrong implementation then bug life cycle will be processing for further and completed until problem is solved and “QA/QA Team” make status “fixed” on “defect report”
