@jdufresne @sww314 how do we feel about codecov? I added it in a pique of interest at some point, anything you guys think works better or that we are missing?

This extra new line is causing flake8 to fail. If you remove it Travis should be green again.

@jschneier I have no strong opinion. I think most PRs -- especially features and bug fixes -- should come with tests. But I don't find the coverage report all the useful personally. I'm ok either way.

[sww314]

@jschneier I agree with Jon. Tests are critical for features and bug fixes. I do not pay much attention to the code coverage report.
