Which sentence is correct.
Defects have been fixed and tested by QA. No issues found furthermore. So, what should QA has to write?
Defect XXX has been verified. No issues found.
Defect XXX has been validated. No issues found
Verification answers the question: "Are we building the product right?" Does it conform to its specification?
Validation answers the question: "Are we building the right product?" Is it doing what the user really needs/wants?
To answer the question, it depends on the nature of the defect.
If you confirm the fixes for defect now allow the product to function as intended, you have verified the fixes.
If you confirm the fixes for the defect change the behavior to fulfill the intended usage, you have validated the fixes.
Adj. 1. verified - proved to be true; "a verified claim"
I think validated means the same, both are used for confirmations.
In this case the sentence should be:
Defect XXX fixes have been verified.
Since its not the defect that is verified, that would mean it was reproduced, but you want to say it was resolved correctly.
Personally I would just set a company standard, it doesn't really matter what the terminology is, as-long everyone in your company understands what it means.
Maybe its better to ask on https://english.stackexchange.com/
First of all QA dosen't (or rather can't) do antyhing on its on. Read the first sentence carefully, I've written "its" and not his or her. Any guesses why?
Well QA (I'm assuming you mean Quality Assurance) is a process. Process doesn't do anything. Someone implements the process to get something done. You might want to Google it to learn more about the process.
And now to the question, I prefer to write "Issue has been resolved by " and then close the bug. This works well with my project team/stakeholders. What others write is totally upto them and their team's mutual understanding.
Happy Testing :)
