The way it works at Google is that there is no syncing necessary. I edit code in a browser IDE. I build and run code on a cloud machine that is automatically synchronized with the state of a virtual workspace I'm editing with the browser IDE. No file containing code or test input is ever stored on my laptop's filesystem. This works great and is basically identical to working on my laptop directly except that my terminal is running over ssh rather than locally.
