# --description--

请注意，本项目在 [这个 Repl.it 项目](https://repl.it/github/freeCodeCamp/boilerplate-mochachai) 的基础上进行开发。你也可以从 [GitHub](https://repl.it/github/freeCodeCamp/boilerplate-mochachai) 上克隆。

接下来，我们将了解如何使用请求的 payload（body）发送数据。

我们需要测试一个 PUT 请求，`'/travellers'` 接收如下的 JSON 对象：

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

响应数据如下：

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

更多细节请查看服务器代码。

# --instructions--

发送  

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

替换 `assert.fail()` 使测试通过。 分别测试 1) `status`，2) `type`，3) `body.name`，4) `body.surname` 请按照以上顺序书写断言，顺序错误会影响此挑战的判定。

# --hints--

不应有未通过的测试

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=functional&n=2').then(
    (data) => {
      assert.equal(data.state, 'passed');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```

你需要测试 'res.status' 是否为 200

```js
(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);
    }
  );
```

你需要测试 'res.type' 是否为 'application/json'

```js
(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.match(data.assertions[1].args[1], /('|")application\/json\1/);
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```

你需要测试 'res.body.name' 是否为 'Cristoforo'

```js
(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.match(data.assertions[2].args[1], /('|")Cristoforo\1/);
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```

你需要测试 'res.body.surname' 是否为 'Colombo'

```js
(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.match(data.assertions[3].args[1], /('|")Colombo\1/);
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```
