Working with iFrames in Cypress - Test Automation Cookbook

This was a big help. Thank you.

Is there a way to use find to get access to the class?

It almost worked for me, I needed to add one more line to make sure that the iframe isn't empty

.its('0.contentDocument.body')
.should('not.be.empty')
...

document.querySelectorAll('iframe')[1].contentDocument.body
It says that my 2 iframes have a null content :')
I can't understand

Can you please help me how to use xpath for iframes in cypress?

Hi dear friend,I would like to know if it is possible to access the third party iframe when it is already in production

thank you so much for this!
