There is this tool called openQA which is open source and is used by SUSE, openSUSE, Fedora and to some extent by Debian to test distributions as an automated testing tool, you can think of it as Selenium but for operating systems.
While we have some documentation, we struggle a bit to spread the knowledge among users, and would like to know if stack overflow is really a good place to start building a knowledge base under a tag like selenium-webdriver for example does.
