# --description--

As a reminder, this project is being built upon the following starter project on [Replit](https://replit.com/github/freeCodeCamp/boilerplate-mochachai), or cloned from [GitHub](https://github.com/freeCodeCamp/boilerplate-mochachai/). This exercise is similar to the preceding one. Look at it for the details.

Now that you have seen how it is done, it is your turn to do it from scratch.

# --instructions--

Within `tests/2_functional-tests.js`, alter the `'send {surname: "da Verrazzano"}'` test (`// #4`):

Send the following JSON response as a payload to the `/travellers` route:

```json
{
  "surname": "da Verrazzano"
}
```

Check for the following, within a `request.end` callback:

1.  `status`
2.  `type`
3.  `body.name`
4.  `body.surname`

Follow the assertion order above - we rely on it. Be sure to remove `assert.fail()`, once complete.

# --hints--

All tests should pass

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=functional&n=3').then(
    (data) => {
      assert.equal(data.state, 'passed');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```

You should test for 'res.status' to be 200

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=functional&n=3').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);
    }
  );
```

You should test for 'res.type' to be 'application/json'

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=functional&n=3').then(
    (data) => {
      assert.equal(data.assertions[1].method, 'equal');
      assert.equal(data.assertions[1].args[0], 'res.type');
      assert.match(data.assertions[1].args[1], /('|")application\/json\1/);
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```

You should test for 'res.body.name' to be 'Giovanni'

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=functional&n=3').then(
    (data) => {
      assert.equal(data.assertions[2].method, 'equal');
      assert.equal(data.assertions[2].args[0], 'res.body.name');
      assert.match(data.assertions[2].args[1], /('|")Giovanni\1/);
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```

You should test for 'res.body.surname' to be 'da Verrazzano'

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=functional&n=3').then(
    (data) => {
      assert.equal(data.assertions[3].method, 'equal');
      assert.equal(data.assertions[3].args[0], 'res.body.surname');
      assert.match(data.assertions[3].args[1], /('|")da Verrazzano\1/);
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```
