How does the Ubuntu team assures that bugs won't appear again?
I have seen it several times. A package is unusable after installing.
Yes, sometimes the bugs get fixed very fast.
But I see no effort to improve the automated testing, so that the bug won't appear again.
Here are two examples which affected me during the last two weeks:
- https://bugs.launchpad.net/ubuntu/+source/vsftpd/+bug/1219857
- https://bugs.launchpad.net/ubuntu/+source/python3.4/+bug/1290847
There are more examples, but listing them is not part of the question.
One comment from the vsftp
bug page:
Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.
OK, but "testing" in the above quote is manual testing.
To ensure quality automated testing is needed.
For me manual testing is a waste of time. On the other hand, building automated tests does ensure quality.
Here again the question:
How does the Ubuntu team assures that bugs don't appear again?
History of this question
First the title was "How does the Ubuntu team do assure that bugs don't appear again?". Now it is "How does the Ubuntu team do automated testing?". This was done because I believe that manual testing is not a solution. Please don't down-vote answers which only explain the way manual testing is done.
