Is this still a problem? I just ran a travis test with this file:

$ cat .travis.yml
language: "python"
python:
    - "2.7"
    - "3.4"
    - "3.5"
    - "3.6"
install:
    - pip install flake8 mock==2.0.0
script:
    - flake8 
    - python setup.py test

and the job passed just fine. I'll follow up with a PR
