Hello <@715580668045951047>  thank you for your help. I'll for sure check out your lessons. I 'm subscibing your YouTube channel ;). You are doing greate job. 

For now I found the solution using stub

`const stub = cy.stub();
cy.document().then(doc => {
  doc.documentElement.requestFullscreen = stub
})
cy.get('input[name="password"]')
  .type(password)
  .then(() => expect(stub).to.be.called)`
