Comment 4 for bug 1372950

Boden, you missing the whole point.
From platform package maintainers point of view - when building package we just need to run unit tests without installing whole project.
Just to be clear, try to run test suit within tox by exclude int-tests part. And you'll see the issue.
Steps:
clone
build env
run testr

Thats all. For me it looks like a bug because of incorrect mocking and expecting that Trove is installed into the system(which actually tox does for its own env) which is wrong from developers point of view.
