[wandmagic]

Committer Notes

After switching the run environment of the dev-constraint script we neglected to update our method of finding the constraint directory path for windows.

this adds a github action to assure that the test script runs correctly in windows and linux

I am fine with that. Sorry for minor nits, I am fine with the action to test across platforms and everything else looks great.

output of the windows test doesn't fail but is not behaving as expected?!
I'm going to re-test on my windows box again before we merge this
