I recently saw something pretty cool on kaggle. When you fill out and run cells in their tutorial notebooks you get pretty much like live feedback, if you did it right or not. I would love to be able to implement my own exercises this way, so that I can hand those notebooks out to my class and the students would get immediate feedback on their programming.
So far I seem to be unable to find how this is done or maybe I miss the right words to put into Google. I found the nbgrader, but that isn't exactly what I was searching for.
Is there a way to do such evaluation directly in the notebooks, or does Kaggle probably use some other software in the backend to get this effect of direct evaluation?
Or can I maybe use unittests in some fashion to get such an effect?
