mocking window.print

Had anyone tried mocking window.print?

I have a scenario where I need to click on a button that window.print’s something, in order to move to the next step, and the test remains stuck in the browser print dialog box at the moment.

I tried with

cy.visit(url, { onBeforeLoad: win => cy.stub(win, 'print').returns(undefined) })

also with

cy.window(win => cy.stub(win, 'print').returns(undefined))

but each time I click on the printing button, I’m prompted with the browser print preview box.

Thank you!

it('can stub print', function () {
  cy.visit('/inner.html', {
    onBeforeLoad: (win) => {
      cy.stub(win, 'print')
    }
  })

  cy.window().then((win) => {
    win.print()

    expect(win.print).to.be.calledOnce
  })
})

Hello @brian-mann I trying to stub print preview but getting, could you please help, Ultimately I want to close print preview or somehow avoid from opening,
expected print to have been called exactly once, but it was never called

My code looks like cy.window().then(win => { cy.stub(win, ‘print’).as(‘print’); });
cy.get(‘my locator’).click(); // this click event opens print widdow(Only after closing print preview window my API call happens). cy.get(‘@print’).should(‘have.been.calledOnce’);
