Fixes #314.

defaults to no multiprocessing
raises warnings if multiprocessing is used

This is a boring PR, but f.ex before merge one needs #315 .

@alexcjohnson maybe I missed some other things, but I'd say this is done.

.travis.yml

-    - python  qcodes/test.py --skip-coverage
-    - python  qcodes/test.py --mp-spawn
+    - python  qcodes/test.py --skip-coverage -f
+    - python  qcodes/test.py --mp-spawn -f


do we really want to fail fast on travis? I'd think a full failure report is more useful.

Also, if we're not supporting multiprocessing for now anyway, is it really worthwhile running the tests in both modes?

yes, because there are still people that just use multiprocessing, and knowing when we break things is useful.
The -f was just so that people read the output, it seems like it's always ignored, so maybe if it's shorted it's easier ?

Oh right, I thought I was going to see that this PR disabled the multiprocessing tests but it didn't :) Good, so we leave both modes in.

If tests pass (which should be a requirement from now on, yes?), this doesn't shorten it at all. All it really does is shorten a horrendous multi-test failure into a single failure - which is enough to disqualify the commit, and it's nice that you get the feedback sooner, but I would still think the debugging cycle would be quicker if you could see all the failures at once. Of course it would be silly to debug only this way - after you see the error(s) on Travis then you test locally while fixing... dunno, if you prefer this way then leave it, in fact you could even go farther and chain the two commands so if the first fails, the spawn version doesn't even run.

@alexcjohnson it shortens the output of the failure, in general people should test locally but I bet most don't .
We could remove the multiprocessing tests all together :D But that's for another PR.

giulioungaretti · 2016-09-14T07:37:59Z

@alexcjohnson on a second though I think I abused the warnings a bit :D I think I will just keep it in the qcodes process !

Oh wow, merging this is going to be a bit tricky.

Just a couple of little cleanup comments, but after those I am happy with it.

Because multiprocessing is not open for public use, unless one really wants to use it. The test are incredibly coupled, so they needed some massaging too. Closes #314.

@giulioungaretti I missed this earlier - what's it about? We shouldn't ever get here, as add_parameter should error first...
