I do think most of the comments here are missing the core point, which isn't so much about whether your development environment is running on your laptop or on the cloud, but more that it's possible to stand up your own environment with a functional version of your product. It's distressingly common that this isn't possible, and you can only test and integrate your code in a single shared development environment, or worse, production, and that neither of these are actually reproducible.
