Seems Travis can't install dependencies, though that was as clear as the error looked to me upon a quick glance.

This branch doesn't just remove olympia.perf but adds coverage tracking, can we split those please?

[andymckay]

I give up on coveralls, cannot get py.test to pickup pytest-cov, works locally just fine, but theres always that fun difference that travis use tox which is completely different from our local environments see also issue mozilla/addons#2401.

How that the coverage stuff is not in the PR anymore, lgtm

Should we open a github issue for properly integrating coveralls?

[andymckay]

Maybe, do developers want coveralls in?

[EnTeQuAk]

having an automatic coverage report is quite nice, it's more important for library-owners but if it works and the effort is reasonable, let's do it. Or at least try to integrate it at some point. I doubt it's important though.

Do consider alternatives to coveralls though, like https://codecov.io/ ? I don't know which one is the best, I just had to fight with coveralls in the past so maybe there are decent alternatives we should explore.
