Abstract (at least 300 words to describe your proposal)

This presentation is an overview for a general audience of the systems in place, both computer and human, that help us find and fix software problems before those problems reach the people who use Wikipedia.

On the technical side, we will review and diagram the path taken by the automated regression tests that run in various browsers. We retrieve these tests from source control, use a Continuous Integration tool on one hosted service to start the tests, create new browser instances on another hosted service, point those browsers to the beta labs cluster and the test2wiki test environments, then collect and report the results of every test. This happens at least twice per day, every day.

Then we will trace the path of a software bug through the human beings who handle it. Someone working in Quality Assurance (usually the presenter of this talk) analyzes the test results and reports the bug. The Bug Wrangler assigns importance and alerts appropriate parties if necessary. The feature teams and developers discuss the bug and fix it. The Release Manager makes sure that the fix gets handled properly all the way to production. We will show examples where we prevented significant problems from reaching Wikipedia users.

We do not find bugs every day, but we do find them often. When that happens, the entire cycle from running the automated tests to getting the bug fixed before deployment happens routinely in less than twelve hours, day after day, week after week, month after month. We would like to tell you about it.
