The openQA-based testing system has recently been integrated into KDE Linux (hooray!), and I thought it was about time I did a little write-up. The nature of KDE Linux, in which the whole system ships as a single signed image rather than a pile of packages, is (in theory) wonderful for reliability. However, this raises an uncomfortable question: how do we make sure that image actually works before we ship it to people? OpenQA is the answer!
