安裝 mocha, chai,mochawesome,istanbul

npm install mocha chai mochawesome istanbul@1.0.0-alpha.2 --save-dev

注意1：

istanbul 版本為 "^1.0.0-alpha.2"

為 istanbul 支持ES6語法安裝依賴包：

npm i babel-cli babel-register babel-plugin-istanbul babel-preset-env cross-env mocha chai nyc --save-dev

注意2:

為了使 istanbul 支持ES6語法，在package.json加入： "nyc": {"require": ["babel-register"],"reporter": ["lcov","text"],"sourceMap": false,"instrument": false}

注意3:

為了使 istanbul 支持ES6語法，在.babelrc加入：

.babelrc

{"presets": ["env"],"env": {"test": {"plugins": ["istanbul"]}} }

package.json

{"name": "100","version": "1.0.0","description": "小貓快跳","main": "game.js","directories": {"test": "test"},"scripts": {"test1": "./node_modules/.bin/istanbul cover ./node_modules/.bin/_mocha test/*.js -- --require babel-register","test":"cross-env NODE_ENV=test nyc mocha"},"author": "wangshuxian6","license": "MIT","devDependencies": {"babel-cli": "^6.26.0","babel-plugin-istanbul": "^4.1.5","babel-preset-env": "^1.6.1","babel-register": "^6.26.0","chai": "^4.1.2","cross-env": "^5.1.3","grunt": "^1.0.1","grunt-contrib-watch": "^1.0.0","grunt-eslint": "^20.1.0","istanbul": "^1.0.0-alpha.2","mocha": "^5.0.1","mochawesome": "^3.0.2","nyc": "^11.4.1"},"nyc": {"require": ["babel-register"],"reporter": ["lcov","text"],"sourceMap": false,"instrument": false} }

mocha.opts

--require babel-core/register --recursive --reporter mochawesome --bail

最終：

運行nom run test 或 nom run test2 都可以
