如何从赛普拉斯工具中的元素获取价值？

Question

I have a problem with taking value of the element like:

<div class="Test">Number 10</div>

Let say, that I have 10-20 classes with values like here, then I can use:

cy.get('.Test').invoke('text').as.('Field1')

to get proper value, but it is only possible in different test by using this.Field1. How to get value in the same test without using: then and .text() ?

Is it possible? I have many fields and I would like do it in one single test to check proper values in the next view.

Did anyone has similar problem? Thanks

It sounds as though you may want to use .its

cy.get('selector').its(propertyName).should('contain', 'string')

its needs to be chained off a previous command like get. You can also use this in a function as per Cypress's example

Cypress shows an example for DOM elements

Get the length property of a DOM element

cy
  .get('ul li')       // this yields us a jquery object
  .its('length')      // calls 'length' property returning that value
  .should('be.gt', 2) // ensure the length is greater than 2
})

You can access functions to then drill into their own properties instead of invoking them.

// Your app code
// a basic Factory constructor
const Factory = (arg) => {
  // ...
}

Factory.create = (arg) => {
  return new Factory(arg)
}

// assign it to the window
window.Factory = Factory

cy
  .window()                 // yields window object
  .its('Factory')           // yields Factory function
  .invoke('create', 'arg')  // now invoke properties on itv

You can drill into nested properties by using dot notation.

const user = {
  contacts: {
    work: {
      name: 'Kamil'
    }
  }
}

cy.wrap(user).its('contacts.work.name').should('eq', 'Kamil') // true
