title: Run Functional Tests on an API Response using Chai-HTTP III - PUT method
challengeType: 2
forumTopicId: 301590
localeTitle: 使用 Chai-HTTP 测试 API 响应结果 (3)—PUT 方法
---

## Description
<section id='description'>
请注意，本项目在 <a href="https://repl.it/github/freeCodeCamp/boilerplate-mochachai">这个 Repl.it 项目</a> 的基础上进行开发。你也可以从 <a href='https://repl.it/github/freeCodeCamp/boilerplate-mochachai'>GitHub</a> 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，<code>'/travellers'</code> 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
<section id='instructions'>
发送 <br>

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

## Tests

```yml
tests:
  - text: 不应有未通过的测试
    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: 你需要测试 'res.status' 是否为 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: 你需要测试 'res.type' 是否为 '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.match(data.assertions[1].args[1], /('|")application\/json\1/);}, xhr => { throw new Error(xhr.responseText); })
  - text: 你需要测试 'res.body.name' 是否为 '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.match(data.assertions[2].args[1], /('|")Cristoforo\1/);}, xhr => { throw new Error(xhr.responseText); })
  - text: 你需要测试 'res.body.surname' 是否为 '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.match(data.assertions[3].args[1], /('|")Colombo\1/);}, xhr => { throw new Error(xhr.responseText); })
