Access a new window - cypress.io

Solution 1:

Accessing new windows via Cypress is intentionally not supported.

However, there are many ways this functionality can be tested in Cypress now. You can split up your tests into separate pieces and still have confidence that your application is covered.

  1. Write a test to check that when performing the action in your app, the window.open event is called by using cy.spy() to listen for a window.open event.
cy.visit('http://localhost:3000', {
  onBeforeLoad(win) {
    cy.stub(win, 'open')
  }
})

// Do the action in your app like cy.get('.open-window-btn').click()

cy.window().its('open').should('be.called')
  1. In a new test, use cy.visit() to go to the url that would have opened in the new window, fill in the fields and click the buttons like you would in a Cypress test.
cy.visit('http://localhost:3000/new-window')

// Do the actions you want to test in the new window

Solution 2:

I am not cypress expert, just started using it few days ago, but I figured out this kind solution for stateful application with dynamic link:

// Get window object
cy.window().then((win) => {
  // Replace window.open(url, target)-function with our own arrow function
  cy.stub(win, 'open', url => 
  {
    // change window location to be same as the popup url
    win.location.href = Cypress.config().baseUrl + url;
  }).as("popup") // alias it with popup, so we can wait refer it with @popup
})

// Click button which triggers javascript's window.open() call
cy.get("#buttonWhichOpensPopupWithDynamicUrl").click()

// Make sure that it triggered window.open function call
cy.get("@popup").should("be.called")

// Now we can continue integration testing for the new "popup tab" inside the same tab

Is there any better way to do this?

Solution 3:

// We can remove the offending attribute - target='_blank'
      // that would normally open content in a new tab.
      cy.get('#users').invoke('removeAttr', 'target').click()

      // after clicking the <a> we are now navigated to the
      // new page and we can assert that the url is correct
      cy.url().should('include', 'users.html')
