I'd just like to let other Phaser game devs know, that using Nightwatch and my new Nightwatch extension, you can now end to end test your phaser games. It's early days for this Nightwatch extension, but you can test your states and that your game loads... And calling components in your game from the tests is going to be added in the next day or two. I've been trying to work out how to get a decent e2e test suite into Canvas based games developed for the web, and think this pretty much nails it. If you like it, please feel free to try it. https://www.npmjs.com/package/phase-2-e
