title: Run Functional Tests on an API Response using Chai-HTTP III - PUT method
challengeType: 2
---

## Description
<section id='description'>
As a reminder, this project is being built upon the following starter project on <a href='https://glitch.com/#!/import/github/freeCodeCamp/boilerplate-mochachai/'>Glitch</a>, or cloned from <a href='https://github.com/freeCodeCamp/boilerplate-mochachai/'>GitHub</a>.
In the next example we'll see how to send data in a request payload (body).
We are going to test a PUT request. The <code>'/travellers'</code> endpoint accepts a JSON object taking the structure :

```json
{
  "surname": [last name of a traveller of the past]
}
```

The route responds with :
 
```json
{
  "name": [first name], "surname": [last name], "dates": [birth - death years]
}
```

See the server code for more details.

## Instructions
<section id='instructions'>
Send <br>

```json
{
  "surname": "Colombo"
}
```

Replace <code>assert.fail()</code> and make the test pass.
Check for 1) <code>status</code>, 2) <code>type</code>, 3) <code>body.name</code>, 4) <code>body.surname</code>.
Follow the assertion order above, We rely on it.

## Tests

```yml
tests:
  - text: All tests should pass
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=functional&n=2').then(data => { assert.equal(data.state,'passed'); }, xhr => { throw new Error(xhr.responseText); })
  - text: You should test for 'res.status' to be 200
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=functional&n=2').then(data => { assert.equal(data.assertions[0].method, 'equal'); assert.equal(data.assertions[0].args[0], 'res.status'); assert.equal(data.assertions[0].args[1], '200');}, xhr => { throw new Error(xhr.responseText); })
  - text: You should test for 'res.type' to be 'application/json'
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=functional&n=2').then(data => { assert.equal(data.assertions[1].method, 'equal'); assert.equal(data.assertions[1].args[0], 'res.type'); assert.equal(data.assertions[1].args[1], '\'application/json\'');}, xhr => { throw new Error(xhr.responseText); })
  - text: You should test for 'res.body.name' to be 'Cristoforo'
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=functional&n=2').then(data => { assert.equal(data.assertions[2].method, 'equal'); assert.equal(data.assertions[2].args[0], 'res.body.name'); assert.equal(data.assertions[2].args[1], '\'Cristoforo\'');}, xhr => { throw new Error(xhr.responseText); })
  - text: You should test for 'res.body.surname' to be 'Colombo'
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=functional&n=2').then(data => { assert.equal(data.assertions[3].method, 'equal'); assert.equal(data.assertions[3].args[0], 'res.body.surname'); assert.equal(data.assertions[3].args[1], '\'Colombo\'');}, xhr => { throw new Error(xhr.responseText); })
