A library that's kind enough to tell you "No" when you need it.
npm install
npm install --global gulp (if you don't already have gulp installed)
gulp test to start karma in continuous integration mode.
Write tests! 😃
Needs Chrome 43+ (this is why currently karma is configured to ask for Chrome Canary). If you want to make it for an earlier version of Chrome or a rendering engine that doesn't keep DOM properties on prototypes, I am unlikely to take your patches. My apologies -- trying to keep this simple. However, would be happy have help to fix any cross-browser problems.
