@nathanshammah I recall that you were looking into something for this? Did you have suggestions in mind?

For the main documentation, I don't know.

However if we want a list of tutorials/examples/implementations which are automatically executed this is great:
https://sphinx-gallery.github.io/stable/index.html
For example this is a typical result:
https://pytorch.org/tutorials/

The source of each example is just python script with comments. The rest is automatically built by sphinx-gallery.

@willzeng In the comment to #72 I meant that I think it is already done, as we have doctest as extension in the conf.py file. But building it and playing with the python block, I do not see a clear error message. So I will investigate this further.

@andreamari I really like sphinx gallery. We are currently adding it to QuTiP. I did not include it here as extension as it was giving some error in the conf.py but I think it would be amazing to include it, will look into it and ping you if I get stuck.

Ok, so there are basically three tools that help with this: mainly doctest (python core) and then pytest, which that does testing in general, and sphinx, which builds the docs.
It took some time to disentangle this, and I am not completely sure of the findings, but at least happy of what's somewhat clearer now:

For the code base, one can use doctest to test docstrings in modules. This can be called in various ways. Best would be to set up an automated script in a test file. pytest+doctest is also possible. In any case it would be nice to implement this inside CI workflow in the .github file.
For the documentation: Running from bash make doctest just like make html and make latexpdf, runs the tests of both modules (as it includes them in the autodoc) and of the guide, and gives a report. This is thanks to the sphinx-doctest extension inserted in the conf.py file.

Currently, I added a dummy example in factories.py on a private branch, to check what was happening, below is copied the quite long error message. Basically the modules need to be implicitly imported for doctest to properly run the script.
