update tests/ for pytest

[juippis]

Note: I have no idea what I'm doing.

I used https://pypi.org/project/nose2pytest/,
manually removed from nose.tools import...,
manually added import pytest,
manually sed'd assert_raises to pytest.raises,
and with these tests pass for me.

python3.8 -m pytest -vv -ra -l -Wdefault --color=no -o console_output_style=count -p no:cov -p no:flake8 -p no:flakes -p no:pylint -p no:markdown -p no:sugar -p no:xvfb
