Javascript 检索Cypress fixture JSON数据的所有类似键值

我很难找到一种干净的方法从Cypress fixture JSON文件中的同一个key-in对象中检索所有值的值

例如，在下面名为myPeople.JSON的JSON文件中，我只需要people下所有对象的firstName值

如果我想检索people下的所有对象，我可以执行cy.fixturemyPeople.itspeople，它将漂亮地返回所有对象

事实证明，收回所有firstName值是很困难的。我尝试了以下方法来检索这些值，但它们没有达到我预期的效果

cy.fixture("myPeople").its("people").its("firstName") //This doesn't work likely because it expects a specific object under the people node to look up its firstName key's value

但是，如果传入显式索引，它将返回该索引的firstName值：

cy.fixture("myPeople").its("people").its(0).its("firstName") //This returns the value "Bob".

我在这里遗漏了什么？

不考虑Cypress本身，您似乎想要使用JavaScript映射函数

例如：

let people = {
  "people": [
    {
      "firstName": "Bob",
      "lastName": "Dawson"
    },
    {
      "firstName": "Tom",
      "lastName": "Wild"
    },
    {
      "firstName": "Sally",
      "lastName": "Rose"
    }
  ]
}

let firstNames = people.people.map(person => person.firstName)

console.log(firstNames) // --> [ 'Bob', 'Tom', 'Sally' ]

一个选项是使用简单的for循环，并从fixtures文件访问所有数组元素

describe('Get first Name from fixtures', () => {

  beforeEach(() => {
    //Load Fixture File
    cy.fixture('myPeople.json').as('myPeople')
  })

  it('Test', () => {
    cy.get('@myPeople').then((myPeople) => {
      for (var i = 0; i < myPeople.people.length; i++) {
        //Print the first Names
        cy.log(myPeople.people[i].firstName)
      }
    })
  })
})

在Cypress中，您可以像这样应用map.cy.fixturemyPeople.itspeople.thenpeople=>people.mapp=>p.firstName我知道这是一件小事，我完全想过头了。这就成功了，谢谢你@Ackroydd还专门为Cypress提供了一个简洁的解决方案，效果很好。在Cypress中，您可以像这样应用map cy.fixturemyPeople.itspeople.thenpeople=>people.mapp=>p.FirstName我知道这是一件小事，我完全想过头了。这就成功了，谢谢你@Ackroydd还专门为Cypress提供了一个简洁的解决方案，效果很好。
