Visit a remote URL.

Syntax

cy.visit(url)
cy.visit(url, options)

Usage

{% fa fa-check-circle green %} Correct Usage

cy.visit('http://localhost:3000')    // Yields the window of the remote page

Arguments

{% fa fa-angle-right %} url (String)

The URL to visit.

Cypress will be prefix the URL with the baseUrl configured in your {% url 'network options' configuration#Global %} if you've set one.

{% fa fa-angle-right %} options (Object)

Pass in an options object to change the default behavior of cy.visit().

Option	Default	Description
log	true	{% usage_options log %}
onBeforeLoad	function	Called before your page has loaded all of its resources.
onLoad	function	Called once your page has fired its load event.
timeout	{% url pageLoadTimeout configuration#Timeouts %}	{% usage_options timeout cy.visit %}

You can also set all cy.visit() commands' pageLoadTimeout and baseUrl globally in {% url 'configuration' configuration %}.

Yields {% helper_icon yields %}

{% yields sets_subject cy.visit 'yields the window object after the page finishes loading' %}

Examples

Url

Visit a local server running on http://localhost:8000

cy.visit() resolves when the remote page fires its load event.

cy.visit('http://localhost:8000')

Options

Change the default timeout

// Wait 30 seconds for page 'load' event
cy.visit('/index.html', { timeout: 30000 })

Provide an onBeforeLoad callback function

onBeforeLoad is called as soon as possible, before your page has loaded all of its resources. Your scripts will not be ready at this point, but it's a great hook to potentially manipulate the page.

cy.visit('http://localhost:3000/#dashboard', {
  onBeforeLoad: function(contentWindow){
    // contentWindow is the remote page's window object
  }
})

Using onBeforeLoad

{% note info %} Check out our example recipes using cy.visit()'s onBeforeLoad option to:

• {% url 'Bootstrap app data' working-with-the-backend-recipe %}
• {% url 'Set a token to localStorage for login' logging-in-recipe %}
• {% url 'Stub window.fetch' stubs-spies-and-clocks-recipe %} {% endnote %}

Provide an onLoad callback function

onLoad is called once your page has fires its load event. All of the scripts, stylesheets, html and other resources are guaranteed to be available at this point.

cy.visit('http://localhost:3000/#/users', {
  onLoad: function(contentWindow){
    // contentWindow is the remote page's window object
    if (contentWindow.angular) {
      // do something
    }
  }
})

Notes

Redirects

Visit will automatically follow redirects

// we aren't logged in, so our webserver
// redirected us to /login
cy.visit('http://localhost3000/admin')
cy.url().should('match', /login/)

Protocol

Protocol can be omitted from common hosts

Cypress automatically prepends the http:// protocol to common hosts. If you're not using one of these 3 hosts, then make sure to provide the protocol.

cy.visit('localhost:3000') // Visits http://localhost:3000
cy.visit('0.0.0.0:3000')   // Visits http://0.0.0.0:3000
cy.visit('127.0.0.1:3000') // Visits http://127.0.0.1:3000

Web Server

Cypress can optionally act as your web server

Cypress will automatically attempt to serve your files if you don't provide a host. The path should be relative to your project's root folder (where cypress.json is located).

Having Cypress serve your files is useful in simple projects and example apps, but isn't recommended for real apps. It is always better to run your own server and provide the url to Cypress.

cy.visit('app/index.html')

Prefixes

Visit is automatically prefixed with baseUrl.

Configure baseUrl in the cypress.json file to prevent repeating yourself in every single cy.visit() command. Read more about {% url 'configuration' configuration %}.

{
  "baseUrl": "http://localhost:3000/#/"
}

cy.visit('dashboard') // Visits http://localhost:3000/#/dashboard

Window

Visit will always yield the remote page's window object when it resolves

cy.visit('index.html').then(function(contentWindow)){
  // contentWindow is the remote page's window object
})

Routing

Preventing XHR / AJAX requests before a remote page initially loads

One common scenario Cypress supports is visiting a remote page and also preventing any AJAX requests from immediately going out.

You may think this works:

// this code may not work depending on implementation
cy.visit('http://localhost:8000/#/app')
cy.server()
cy.route('/users/**', 'fx:users')

But if your app makes a request upon being initialized, the above code will not work. cy.visit() will resolve once its load event fires. The {% url cy.server() server %} and {% url cy.route() route %} commands are not processed until after cy.visit() resolves.

Many applications will have already begun routing, initialization, and requests by the time the cy.visit() in the above code resolves. Therefore creating a {% url cy.server() server %} will happen too late, and Cypress will not process the requests.

Luckily Cypress supports this use case. Simply reverse the order of the commands:

// this code is probably want you want
cy.server()
cy.route('/users/**', {...})
cy.visit('http://localhost:8000/#/app')

Cypress will automatically apply the server and routes to the very next cy.visit() and does so immediately before any of your application code runs.

Rules

Requirements {% helper_icon requirements %}

{% requirements page cy.visit %}

Assertions {% helper_icon assertions %}

{% assertions wait cy.visit %}

Timeouts {% helper_icon timeout %}

{% timeouts page cy.visit %}

Command Log

Visit example application in a beforeEach

beforeEach(function(){
  cy.visit('https://example.cypress.io/commands/viewport')
})

The commands above will display in the command log as:

When clicking on visit within the command log, the console outputs the following:
