The Fedora Project holds regular Test Days to help put releases or individual components through their paces. This week, Fedora’s Test Day will focus on Cockpit, which will be part of the Fedora Atomic Host in Fedora 21.
If you’d like to participate, be sure to look over the Test Day on the Fedora wiki and check out the prerequisites, test cases, and how to file results and bugs.
Questions? Ask on the cockpit-devel mailing list.
