The #1 programmer excuse for legitimately slacking off used to be “My code’s compiling”. These days it’s more likely “I’m running the tests”. We have time for a coffee (or two or three). That’s what we turn into code after all. We waste not only a lot of our time waiting until the very end of the build to see tests which we have just written failing, but also tons of resources making our CI servers sweat and having enormous queues of pending jobs. But what’s even more important - we switch contexts and thus we loose focus. Maybe we can test smarter? Join us in this workshop and bring your laptop to learn about a new tool we are working on that you stay in the zone and never waste time again. We know which tests you want to run.
