One of the most exciting features of Node in the past months is the new test runner. But for some reason people don't seem to be using it a lot! In this talk I'll guide you through all the coolest new features this new test runner has, including the ones that I have personally created and worked with. We will go internally in the Node code and see how mocks are implemented and how to work with them, we will also see the next steps for the runner and what we should expect for it in the future. So get ready to make your testing much more integrated with native assertions getting all the gold without having to sacrifice performance!
