Travis CI config to run headless Node tests via Xvfb

.travis.yml

language: node_js
node_js:
  - '6.9.1'
  - '7.0.0'
sudo: false

addons:
  apt:
    packages:
      - xvfb

install:
  - export DISPLAY=':99.0'
  - Xvfb :99 -screen 0 1024x768x24 > /dev/null 2>&1 &
  - npm install

package.json

{
	"scripts": {
		"test": "electron-mocha --renderer test/*.js"
	},
	"devDependencies": {
		"electron": "latest",
		"electron-mocha": "latest"
	}
}
