Add me to the list of people dedicating themselves to trying something in this very area.
I don't exactly know what I'm creating yet (maybe there aren't terms for it yet), because I change things as I go and it's not done yet. But the current vision is a sustainable automation platform, where you can add/change/build/do anything (because it's open source) with what you're working with. So you can create yourself a "testing the app" button and "building the app" button, and that will become something that's available to you. Actually, I'm trying to make it so that those buttons will be automatically available for you as you naturally do the things you'd normally do, but I haven't gotten to this part yet. (Oh, and perhaps instead of buttons you have to press, new output can simply appear on your screen right away.)
In short, my vision agrees very much with what you're saying, but I still have a lot of work to make my project a viable building tool, and it is happening very slowly indeed.
