scenarios with Cypress not recognizing dynamic class selectors during end-to-end tests

cypress testing react JavaScript

I'm working on a personal project and This might be a silly question, but Quick question that's been bugging me - I'm experiencing an scenario with my end-to-end tests using Cypress where it fails to recognize dynamic class selectors that are added after an API call..... For instance, I have a component that fetches data and updates its class based on the response. The specific class `item-loaded` gets added to the item after the API call completes, but Cypress need to seem to find it, resulting in an behavior: `CypressError: Timed out retrying: expected to find element: '.item-loaded', but never found it`. I've tried using `cy.wait()` to give it some time, but that doesn't seem to help. My test code looks like this: ```javascript describe('Dynamic Class Selector Test', () => { it('should find the item with loaded class', () => { cy.visit('/my-page'); // Wait for the API call to complete cy.intercept('GET', '/api/items').as('getItems'); cy.wait('@getItems'); cy.get('.item-loaded').should('exist'); }); }); ``` I also tried using `cy.get('.item-loaded', { timeout: 10000 })` to extend the timeout, but it still fails. I verified in the console that the class is indeed being added after some delay, but Cypress isn't picking it up. Any suggestions on how to handle dynamic class selectors in Cypress tests effectively? I'm using Cypress version 9.0.0 and React version 17.0.2. Thank you! I'm working on a application that needs to handle this. Any ideas what could be causing this? The stack includes Javascript and several other technologies. Any suggestions would be helpful.
