Testing Lightning salesforce version cypress is stuck and not moving forward

[FarazQualitest21]

The moment i am logging in salesforce lighting my cypress is stuck (Your tests are loading)

Do someone have any solution that how can i test saleforce lightning version using cypress

Wouldn't be surprised if this has to do with the Salesforce login process and iframes. Cypress as a whole doesn't like/support iframes, which makes testing Salesforce apps nearly impossible. https://docs.cypress.io/guides/guides/web-security#Cross-origin-iframes

I had something working 3-4 years ago, but it was very flaky and constantly breaking.
Might be worth looking at another library like Playwright or UTAM, which has more support for iframes.

Best of luck!
