test-example.cy.js

import config from './config.json'
import MainPage from '../../page-objects/components/MainPage'
describe('Elements Exist', () => {
   it('Elements exist across the pages', () =>{
       cy.visit(`${config.URL3}`)
       //Element Exists
       cy.get('body')
           .then($body => {
               if ($body.find('.compare-total').length) {
                   return '.compare-total'
           }
           return '.both.text-reset'
           })
           .then(selector => {
           cy.get(selector)
       })
       //Improve Element Exist Method
       MainPage.elExists('.content-products.entry-content.flex-grow-0.order-5.order-md-4 > div > div:nth-of-type(1)')  
   })
