Yield the object passed into .wrap(). If the object is a promise, yield its resolved value.


cy.wrap(subject, options)


Correct Usage

cy.wrap({ name: 'Jane Lane' })


subject (Object)

An object to be yielded.

options (Object)

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

Option Default Description
log true Displays the command in the Command log
timeout defaultCommandTimeout Time to wait for cy.wrap() to resolve before timing out


  • cy.wrap() yields the object it was called with.



Invoke the function on the subject in wrap and return the new value

const getName = () => {
  return 'Jane Lane'

cy.wrap({ name: getName }).invoke('name').should('eq', 'Jane Lane') // true


Wrap elements to continue executing commands

cy.get('form').within(($form) => {
  // ... more commands

  cy.wrap($form).should('have.class', 'form-container')

Conditionally wrap elements

  .then(($button) => {
    // $button is a wrapped jQuery element
    if ($button.someMethod() === 'something') {
      // wrap this element so we can
      // use cypress commands on it
    } else {
      // do something else


You can wrap promises returned by the application code. Cypress commands will automatically wait for the promise to resolve before continuing with the yielded value to the next command or assertion. See the Logging in using application code recipe for the full example.

Simple example

const myPromise = new Promise((resolve, reject) => {
  // we use setTimeout(...) to simulate async code.
  setTimeout(() => {
      type: 'success',
      message: 'It worked!'
  }, 2500)

it('should wait for promises to resolve', () => {
  cy.wrap(myPromise).its('message').should('eq', 'It worked!')
Wrap of promises

Application example

// import application code for logging in
import { userService } from '../../src/_services/user.service'

it('can assert against resolved object using .should', () => {
  cy.log('user service login')
  const username = Cypress.env('username')
  const password = Cypress.env('password')

  // wrap the promise returned by the application code
  cy.wrap(userService.login(username, password))
    // check the yielded object
    .should('be.an', 'object')
    .and('have.keys', ['firstName', 'lastName', 'username', 'id', 'token'])
    .and('contain', {
      username: 'test',
      firstName: 'Test',
      lastName: 'User'

  // cy.visit command will wait for the promise returned from
  // the "userService.login" to resolve. Then local storage item is set
  // and the visit will immediately be authenticated and logged in
  // we should be logged in
  cy.contains('Hi Test!').should('be.visible')

Note: .wrap() will not synchronize asynchronous function calls for you. For example, given the following example:

  • You have two async functions async function foo() {...} and async function bar() {...}
  • You need to make sure foo() has resolved first before invoking bar()
  • bar() is also dependent on some data that is created while after calling other Cypress commands.

If you wrap the asynchronous functions in cy.wrap(), then bar() may be called prematurely before the required data is available:



// this will execute `bar()` immediately without waiting
// for other cy.get(...) functions to complete
cy.wrap(bar()) // DON'T DO THIS

This behavior is due to the function invocation foo() and bar(), which call the functions immediately to return a Promise.

If you want bar() to execute after foo() and the cy.get() commands, one solution is to chain off the final command using .then():


cy.get('some-submit-button').click().then(() => {
  // this will execute `bar()` after the
  // other cy.get(...) functions complete



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


  • cy.wrap(), when its argument is a promise, will automatically wait until the promise resolves. If the promise is rejected, cy.wrap() will fail the test.

  • cy.wrap() will automatically retry until assertions you've chained all pass.


  • cy.wrap() can time out waiting for assertions you've added to pass.

Command Log

Make assertions about object

cy.wrap({ amount: 10 })
  .should('have.property', 'amount')
  .and('eq', 10)

The commands above will display in the Command Log as:

Command Log wrap

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