What is autotest?
Autotest is "a framework for automated testing". It gives us a way to run automated tests and collect results. For more information, see their wiki: https://github.com/autotest/autotest/wiki
How is it used in Fedora?
We're currently using it as the test harness for AutoQA. It handles the dirty work of getting code onto test machines, running it, and holding all the results.
Currently there is a public autotest instance running at http://autoqa.fedoraproject.org. This instance is hosted by the Infrastructure team and managed by QA team. It is not integrated with Fedora account system, so public access to the autotest scheduler web-frontend is not enabled. However, test results are available and links to results are included in all test result emails.
