Promise A+ 测试

1. 安装一下

npm install promises-aplus-tests -D 

2. 手写代码中加入 deferred

MyPromise {
  ......
}

MyPromise.deferred = function () {
  var result = {};
  result.promise = new MyPromise(function (resolve, reject) {
    result.resolve = resolve;
    result.reject = reject;
  });

  return result;
}
module.exports = MyPromise;

3. 配置启动命令

// package.json

"scripts": {
  "test": "promises-aplus-tests my-promise"
},

开启测试

npm run test
