Is there a way to "Simulate" Vive input to allow developing for Vive without one?

I don’t have a Vive. Can’t afford one, don’t have room for one. But my buddy has one. I’d like to be able to make stuff he can run. I’m wondering if there’s a good way to simulate input from the Vive. I’m guessing no but I wanted to see if anyone had come up with something.
