# Run Functional Tests on an API Response using Chai-HTTP III - PUT method

---
## Problem Explanation
To begin, open the file "tests/2_functional_tests.js" and locate the test 'send {surname: "Colombo"}'


---
## Hints

### Hint 1

Using the example above, look at the assertions and how they are making comparisons between the expected and actual values of the response

### Hint 2

You need to use .send() to attach the payload `{surname: 'Colombo'}` to the request

### Hint 3

Replace the `assert.fail()` statement with your own tests checking for status, type, body.name, and body.surname in that order. Remember, all of these values are contained in the response (`res`), and you should expect the response to be of type `'application/json'`.

```js
test('send {surname: "Colombo"}', function(done) {
  // we setup the request for you...
  chai
    .request(server)
    .put('/travellers')
    /** send {surname: 'Colombo'} here **/
    .send({ surname: 'Colombo' })
    // .send({...})
    .end(function(err, res) {
      /** your tests here **/
      assert.equal(res.status, 200, 'response status should be 200');
      assert.equal(res.type, 'application/json', 'Response should be json');
      assert.equal(
        res.body.name,
        'Cristoforo',
        'res.body.name should be "Christoforo"'
      );
      assert.equal(
        res.body.surname,
        'Colombo',
        'res.body.surname should be "Colombo"'
      );

      done(); // Never forget the 'done()' callback...
    });
});
```
