The Plone community has a strong tradition of software testing and continuous integration. But what’s really happening during the half hour or so it takes to test a change to Plone, and is it serving us well? I’ll review our current test processes, the history of how we got here, and point out some opportunities to make it even better. The talk will be focused on testing Plone itself, but a lot of the techniques are also relevant to projects built on top of Plone, and to other web software.
