How to use addPlatformInformation method in Cypress

Well this seems to work, so it tells me I have some more to learn about .should()

cy.get('.check-box-sub-text').should('not.exist');

You can specify which .collapse you want by the content of it's children

cy.contains('.collapse', 'Apple')  // gets the 1st collapse element where child has "Apple" text
  .find('item').eq(1)             // within that, get the 2nd <item>
  .should('have.text', 'Apple 2')

If your actual HTML is more complicated and you want to start with the title element,

cy.contains('.title', 'Apple')  // get the title child with "Apple" text
  .parent()                    // move up to div.collapse
  .find('item').eq(1)         // within that, get the 2nd <item>
  .should('have.text', 'Apple 2')

or siblings navigation

cy.contains('.title', 'Apple')  // get the tile child with "Apple" text
  .siblings('item').eq(1)       // 2nd item sibling
  .should('have.text', 'Apple 2')

I would not bother using the support/index.js, just make a dummy spec and run that

// my-top-10-tests.spec.js

import './login.spec.js' 
import './admin.spec.js' 
import './customer.spec.js'
// and so on

Your route should point to just the path, not the full URL. Try changing it to cy.route("/admin/portfolio/putstrategy").as("updatetrategy")

I'm assuming it's just a snippet from your test, but if you don't have cy.server() before you call into cy.route(), you'll need to add that as well.

I think you can use jQuery .position()

cy.get('#element1')
  .then($el => $el.position().top)  // get 1st top value
  .then(top1 => {
    cy.get('#element2')
      .then($el => $el.position().top)  // get 2nd top value
      .then(top2 => {
        expect(top1).to.be.gt(top2)
      })
  })

Notes

Cypress use jQuery to find elements. Chaining .then($el => ... exposes the jQuery object containing the element, so now you can apply other jQuery functions that are not part of the Cypress commands.

In fact, any other Javascript functions you want.

You can also make reusable functions

const getTop = ($el) = $el.position().top;

cy.get('#element1').then(getTop)  
  .then(top1 => {
    cy.get('#element2').then(getTop)
      .then(top2 => {
        expect(top1).to.be.gt(top2)
      })
  })

Be aware in my js file the following was added automatically;

const { contains } = require("cypress/types/jquery");

deleting this line of code, problem solved

Try to run again without import {cypress as cy} from "cypress"

Based on the Cypress Testing Library examples, instead of passing the role in an object (cy.findByRole({ role: "checkbox" })), you should be passing it as the first argument:

cy.findByRole("checkbox");

Beyond that, as Jonah pointed out, I think your test may be failing because you are trying to assign the return value of cy.findByRole to a variable. In Cypress, everything is asynchronous, so you need to chain your assertions. This is explained in more depth in the Cypress documentation.

Here is your test case rewritten with all of the above in mind:

cy.findByRole("checkbox").should("not.be.checked");
cy.get(".accordion__itemContent").invoke("display").equal("none")
cy.findByRole("checkbox")
  .check()
  .should("be.checked");
cy.get(".accordion__itemContent").invoke("display").equal("block")

Try inverting/reversing your logic.

Get the element with the text, and then its tr parent:

cy.contains('Example Text').parent('.tr');
