- dont test font-wishlist.json
- remove checkFormat as we’re already doing a ton of image processing
and we already test these things in `test-responses.js`
- print to console.error whenever a mock passes. I know .error is
weird, but it’s the only way people can get feedback if they’re
watching on circle, or else it’s a long test to be starting at.
