Tests should be able to run in parallel

[cdonovick]

pytest --workes=auto test_micro.py and pytest --workes=auto test_pe.py fail.

Given how long test_pe.py takes it would be nice to run it in parallel.

Are you using pytest-parallel or pytest-xdist?

[cdonovick]

-parallel. Does xdist work?

Doubt it, wanted to know to lookup the API for getting the thread ID so each thread can create their own unique test/build directory, but that has complications, so I think it makes more sense to do the approach you sketched (each test copies the required files to a tempdir)
