Question

obj= {
  "element-id": 0,
  "measurement": [{
    "from": "2018-10-17T13:40:00Z",
    "to": "2018-10-17T13:45:00Z",
    "value": [{
      "value": 9,
      "label": "fw"
    }, {
      "value": 7,
      "label": "bw"
    }]
  }, {
    "from": "2018-10-17T13:45:00Z",
    "to": "2018-10-17T13:50:00Z",
    "value": [{
      "value": 6,
      "label": "fw"
    }, {
      "value": 8,
      "label": "bw"
    }]
  }]
};

var res = foo(obj);

-- Expected res output:
[ { address: 0,
    datetime: 2018-10-17T13:45:00.000Z, <- this is a javascript Date object
    day: '2018-10-17',
    In: 9,
    Out: 7 },
  { address: 0,
    datetime: 2018-10-17T13:50:00.000Z, <- this is a javascript Date object
    day: '2018-10-17',
    In: 6,
    Out: 8 }]

函数foo应该将对象obj转换为另一个对象。生成的res对象应该是一个数组，其元素的结构均相同，并且所有元素都应包含一个Date对象。我该如何测试？

这是我从您的帖子和评论中了解的内容。如有任何错误，请浏览我。

obj= {
  "element-id": 0,
  "measurement": [{
    "from": "2018-10-17T13:40:00Z",
    "to": "2018-10-17T13:45:00Z",
    "value": [{
      "value": 9,
      "label": "fw"
    }, {
      "value": 7,
      "label": "bw"
    }]
  }, {
    "from": "2018-10-17T13:45:00Z",
    "to": "2018-10-17T13:50:00Z",
    "value": [{
      "value": 6,
      "label": "fw"
    }, {
      "value": 8,
      "label": "bw"
    }]
  }]
};

let arr = [obj]
let foo = []
arr[0].measurement.map(data => {
	let d = new Date()
	foo.push({
		address: 0,
		datetime: d.toISOString(),
		day: d.toISOString().slice(0,10),
		in: data.value.filter(v => v.label == "fw")[0].value,
		out: data.value.filter(v => v.label == "bw")[0].value
		
	})
})
console.log(foo)

如何测试一个返回对象数组的函数，这些对象的元素包含javascript Date对象？
