Load HTML string

[stychu]

Is it possible to load the HTML string I cypress??

I need a way to assert some element existence when doing API calls.

cy.request('/').its('body') <- returns me a HTML string as a response
Can I then somehow load it in the cypress to make operations like on normal page load?

If I do directly

cy.request('/').its('body').should('contain', somestring)

It does the job but unfortunately, this loads the whole HTML string to the cypress command log, and having few of this kind of assertions make cypress run out of memory.

You can skip logging them

cy.request('/').its('body', {log: false})
  .then(text => {
    if (!text.includes(somestring)) {
      throw new Error('Text does not have the expected string')
    }
  })

doing cy.document().invoke('open').invoke({ log: false }, 'write', html) seems to work.

@bahmutov Thanks for this article!
I'm facing a problem in writing the HTML to the document in case if the test already visited a website.
Here is the code snippet:
cy.visit('any url')
// wait until the page is loaded
cy.document().invoke({ log: true}, 'write', html)

Here is what i got:

Can you help me in this?

@OmarSlame can you provide a small repo with a reproducible example?

@OmarSlame did you find a solution for that issue? I am facing the same exact problem

Thanks!

@jprealini Yes, the below working in all cases:
cy.document().then((document) => { document.documentElement.innerHTML = EMAIL_HTML_BODY_YOU_WANT_TO_WRITE })
