Technical changes

In #1025, @benoit-cty mentioned issues with Xdist that were likely to come up with pytest-parallel. Do we not have them here?

The suggested library is not maintained: kevlened/pytest-parallel#104. Our stack is already suffering from outdated dependencies and I don't find it wise to add to this.

What is the performance gain we get from this implementation on some large models?

Fair enough. Performance is only remarkable for county packages like France. Implementing xdist requires changes to the test command. I propose we deal with those, needed nonetheless to upgrade to newest pytest.
