Support for jupyter notebook embeded tests

[ycopin]

Hi,
I'm a fairly naive user of pytest, mostly in some educational context. While it's easy to use doctest & unittest tests within a notebook (see e.g. this gist or my own user case, it seems impossible to do the same with pytest tests, without resorting to plugins or additional dependencies (e.g. ipytest).

I definitely don't know all the gory internal details of pytest, but I wonder why it's not possible to easily embed pytest tests within a notebook, so that I can illustrate different (easier to write) test methods?

What's the problem this feature will solve?

Embed and run pytest tests within a jupyter notebook.

Describe the solution you'd like

A few-line self-consistent solution as possible with unittest, see e.g. this notebook.

Alternative Solutions

The ipytest solution works fine (with extra features), but requires an extra-dependency. I'm looking for a minimal procedure, mostly to illustrate the writing of pytest tests.

Given that there is a project doing this already, and given how testing Jupyter notebooks is something rather exotic in the big picture... I really don't see why this would need to be part of the pytest core. What's the problem with an extra dependency, given that pytest (and Jupyter!) are already third-party packages anyways?

Closing this as not a core responsibility

Point taken, I just wanted to be sure I did not overlook an easy way around. Regarding dependencies, adding new ones to a university system you're not controlling is not always an easy task. Jupyter and pytest are well identified, ipytest much less so...
