ESLint Configuration for Mocha and Chai

Nobody likes false positives! The following configuration works with ESLint 4 with Chai's BDD style should and expect interfaces.

module.exports = {
 "env": {
 "mocha": true
 },
 "rules": {
 "no-unused-vars": [
 "error",
 {
 "varsIgnorePattern": "should|expect"
 }
 ]
 }
}
