I've been experimenting a lot with using Jupyter Notebooks (http://jupyter.org/) to get many features of literate programming.
The tooling can be a bit clunky -- though JupyterLab and some plugins can go a long way. Importing notebooks into other notebooks or modules is still kind of weird even with the `ipynb` library.
However, on the otherside of it all, you have a collection of documents that contain documentation, code, and tests, all side by side and storable with proof of past execution.
I'll take this arrangement over someone's unit test and CI suite every day of the week.
