# wrap

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

## Syntax

```javascript
cy.wrap(subject)
cy.wrap(subject, options)
```

### Usage

 **Correct Usage**

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

### Arguments

 **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](/llm/markdown/app/core-concepts/open-mode.md#Command-Log) |
| `timeout` | [`defaultCommandTimeout`](/llm/markdown/app/references/configuration.md#Timeouts) | Time to wait for `cy.wrap()` to resolve before [timing out](#Timeouts)                              |

### Yields [Learn about subject management](/llm/markdown/app/core-concepts/introduction-to-cypress.md#Subject-Management)

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

## Examples

### Objects

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

```javascript
const getName = () => {
  return 'Jane Lane'
}

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

### Elements

#### Wrap elements to continue executing commands

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

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

#### Conditionally wrap elements

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

### Promises

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](/llm/markdown/app/references/recipes.md#Logging-In) recipe for the
full example.

#### Simple example

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

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

#### Application example 

```javascript
// 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')
  cy.env(['username', 'password']).then(({ username, 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,
        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
  cy.visit('/')
  // 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:

```javascript
cy.wrap(foo())

cy.get('some-button').click()
cy.get('some-input').type(someValue)
cy.get('some-submit-button').click()

// 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()](/llm/markdown/api/commands/get.md) commands, one solution is to chain
off the final command using [.then()](/llm/markdown/api/commands/then.md):

```javascript
cy.wrap(foo())

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

## Rules

### Requirements [Learn about chaining commands](/llm/markdown/app/core-concepts/introduction-to-cypress.md#Chains-of-Commands)

- `cy.wrap()` requires being chained off of `cy`.

### Assertions [Learn about assertions](/llm/markdown/app/core-concepts/introduction-to-cypress.md#Assertions)

- `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](/llm/markdown/app/core-concepts/retry-ability.md)
  until all chained assertions have passed.

### Timeouts [Learn about timeouts](/llm/markdown/app/core-concepts/introduction-to-cypress.md#Timeouts)

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

## Command Log

***Make assertions about object***

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

The commands above will display in the Command Log as:

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