getCookie

Get a browser cookie by its name.

Syntax​

cy.getCookie(name)
cy.getCookie(name, options)

Usage​

Correct Usage

cy.getCookie('auth_key') // Get cookie with name 'auth_key'

Arguments​

name (String)

The name of the cookie to get. Required.

options (Object)

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

OptionDefaultDescription
domainHostname of the current URLRetrieves the cookie from the specified domain
logtrueDisplays the command in the Command log
timeoutresponseTimeoutTime to wait for cy.getCookie() to resolve before timing out

Yields Learn about subject management​

cy.getCookie() yields a cookie object with the following properties:

  • domain
  • expiry (if specified)
  • hostOnly (if specified)
  • httpOnly
  • name
  • path
  • sameSite (if specified)
  • secure
  • value

cy.getCookie() is not a query. It will not retry, or wait for the requested cookie to exist.

cy.getCookie() yields null.

Examples​

Session id​

In this example, on first login, our server sends us back a session cookie.

// assume we just logged in
cy.contains('Login').click()
cy.url().should('include', 'profile')
// retries until cookie with value=189jd09su
// is found or default command timeout ends
cy.getCookie('session_id')
  .should('have.property', 'value', '189jd09su')
  .then((cookie) => {
    // cookie is an object with "domain", "name" and other properties
  })

You can check the cookie existence without comparing any of its properties

cy.getCookie('my-session-cookie').should('exist')

If you need the cookie value, for example to use in a subsequent call

let cookie

cy.getCookie('session_id')
  .should('exist')
  .then((c) => {
    // save cookie until we need it
    cookie = c
  })

// some time later, force the "cy.request"
// to run ONLY after the cookie has been set
// by placing it inside ".then"
cy.get('#submit')
  .click()
  .then(() => {
    cy.request({
      url: '/api/admin',
      headers: {
        'my-token-x': cookie.value,
      },
    })
  })

Using cy.getCookie() to test logging in​

info

Check out our example recipes using cy.getCookie() to test logging in using HTML web forms, logging in using XHR web forms and logging in with single sign on

Rules​

Requirements Learn about chaining commands​

  • cy.getCookie() requires being chained off of cy.

Assertions Learn about assertions​

  • cy.getCookie() will only run assertions you have chained once, and will not retry.

Timeouts Learn about timeouts​

  • cy.getCookie() should never time out.
caution

Because cy.getCookie() is asynchronous it is technically possible for there to be a timeout while talking to the internal Cypress automation APIs. But for practical purposes it should never happen.

Command Log​

Get a browser cookie and make assertions about the object

cy.getCookie('fakeCookie1').should('have.property', 'value', '123ABC')

The commands above will display in the Command Log as:

Command Log getcookie

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

Console Log getcookie

History​

VersionChanges
