Quantum tests

[StefanoChiodino]

On my Mac there are 18 failing tests on master. I was a bit confused, but then noticed that then I submitted a PR they all passed on Travis. I also noticed that travis only runs tests on Linux and I'm assuming this is due to paths differences and that kind of stuff.

Even if you don't care about the system running on Mac this is not a good experience. I'd need to remember which tests are broken, why, wait for Travis to run, and hope that I didn't break them further.

I'll attach an export of the tests.
Test Results — Tox.pdf

What's the result if you run the py36 test only? tox -e py36

those would be included in the first list that I've attached, but here it is:

@StefanoChiodino just asking in case the other tests (py2) could be interfering.
