test CI testing (WIP)

[aixtools]

Just a test PR to better learn how CI testing is working.

Work in progress - should be safe to ignore.

I'm going to close this as you should be able to run the tests on your own fork as well for any necessary experimentation.

Brett, I do not have pypy3 on windows, and what this showed, imho, is that master is not passing it's own requirements. The only change made here is a comment added to tags.py, and it failed at the same point as the PR I submitted.

I have neither the skills nor the resources to research and fix Windows issues that have nothing to do with what I am trying to contribute.

I have no explanation for how it passed #243 - but it did not pass here.

I wish I could be more help, but I cannot for this particular matter.

For the record - I do try and run the tests as thoroughly as I can before I push anything. Learning how coverage works was a real challenge.

Happy holidays.
