* Load CSS in PhantomJS
* Allow to take screenshot in PhantomJS while running tests
For that, one need to run this call:
window.top.callPhantom({'render': 'screenshot.png'});
* Make PhantomJS serve images
* Bonus: those tests now passe in Phantom too
* Add helper to make screenshot in tests
takeScreenshot();
or
takeScreenshot('path/to/screenshot.png');
This prevents us from adding /* eslint no-console: 0 */ each time
we need to use console.log/trace for debugging.
This also means that we will not be blocked if we forget a console
in the tests before commiting, but this should also happen while using
the inline "no-console" config, and given that this only affects tests
files, I think the confort of being able to use console easily worths
the risk of pushing a console in the tests files.
