I should have also added some of my own reasons why pytest is better

tests in Python:

PDB works seamlessly.
- Far less overhead in creating initial tests.
- Trivial fixture support
- Paramaterised tests -- this is incredibly essential / useful.
Another feature that's not often mentioned is pytest discovers tests
all on its
own. You can put a test anywhere labled test_*.py and it will work.
You can
run pytest anywhere in the source as well.
The above are starkly different from unittest where these features
don't exist
or are difficult / have a large overhead to implement.
Ok, I guess I have to adjust my draft of the Python guidelines:
https://lists.rtems.org/pipermail/devel/2020-March/058289.html
I converted an example test from unittest to pytest:

Using plain assert statements is quite nice. Also the "tmpdir" fixture
is really nice.
Chris, what do you think about using pytest in favour of the standard
Python unitttest?
